Medical Diagnoses in Grey's Anatomy: A Comprehensive Review of Medical Conditions in Season 11
- Oct 23
- 17 min read
Season 11 of Grey's Anatomy was a season of profound change, loss, and groundbreaking innovation. Picking up after Cristina Yang's departure, the season charted a new course, introducing Dr. Maggie Pierce and immediately challenging the surgeons with the fallout from the superstorm. The season's medical storylines were defined by a stark contrast: the brilliant, "impossible" surgeries versus the tragic, preventable failures. We witnessed the incredible fight to save Dr. Herman's life with an "inoperable" tumor and the pioneering development of robotic prosthetics. This was all set against the backdrop of personal tragedies, including April and Jackson's devastating loss and, ultimately, the shocking, protocol-defying death of Dr. Derek Shepherd, an event that changed the fabric of the hospital forever.

Episode 1: "I Must Have Lost It on the Wind"
Failed Mitral Valve Secondary to Endocarditis
An unidentified "lost camper" was rescued from the desert after being lost for what was estimated to be one or two months. He presented with extreme dehydration, malnutrition, unstable potassium, and severe Emphysematous Pyelonephritis (E.P.N.) (a necrotic kidney infection). During emergency surgery for his kidney, he went into pulseless V-tach. The new diagnosis was cardiogenic shock from a failed mitral valve resulting from endocarditis.
Fatal Traumatic Brain Injury
Mr. Peterson fell from his roof and presented with severe neurological trauma, hypertension, and bradycardia. The final diagnosis was an epidural bleed, which led to brain herniation. Despite efforts to lower his intracranial pressure (I.C.P.) with Mannitol, the injury was too advanced, and he died.
Other Conditions Mentioned:
Open-book pelvis: A severe, unstable pelvic fracture.
Stage 2 Osteosarcoma: Bone cancer.
Severe Emphysematous Pyelonephritis (E.P.N.): A gas-forming, necrotic infection of the kidney.
Pulseless V-tach: A life-threatening, non-perfusing cardiac rhythm.
Episode 2: "Puzzle with a Piece Missing"
Genetic Dilated Cardiomyopathy (RAF1 Mutation)
Robbie McCutcheon (22) was admitted for a large kidney stone but experienced sustained runs of ventricular tachycardia (V-tach). A work-up revealed dilated cardiomyopathy (DCM). Dr. Pierce, puzzled by the case, ordered a full exome panel, which was only updated the previous week. The test identified a RAF1 mutation as the cause. This discovery was a breakthrough, as the same mutation was found to be the cause of the previously idiopathic cardiomyopathy in the McNeil family children from Season 10.
Other Conditions Mentioned:
Ebstein's malformation: A congenital malformation of the tricuspid valve.
Double inlet left ventricle: A congenital heart defect in a fetus.
Stage IV small cell cancer of the lung: Advanced cancer with liver metastases.
Aortic dissection: A tear in the inner wall of the aorta.
Patent Foramen Ovale (PFO): A "hole in the heart" suspected after a patient had a stroke.
Episode 3: "Got to Be Real"
Targeted Muscle Reinnervation for Prosthetics
Jeff, a wounded warrior, was not a candidate for Dr. Torres's robotic leg because his nerves were not communicating with his muscles after a "crappy amputation." Dr. Avery proposed Targeted Muscle Reinnervation (TMR), a surgical procedure to reroute a nerve (like the deep peroneal) to a functioning muscle (like the biceps femoris). This created a new "traffic route" for nerve signals, allowing them to interface with the 13 sensors in the prosthetic limb.
Traumatic Brain Injury Complicated by Aneurysm and DIC
Steve (35), a motorcyclist who crashed without a helmet, presented with a depressed skull fracture. After surgery for a subdural bleed, a post-op CT scan revealed a large, growing aneurysm. While attempting an endovascular repair, he began to re-bleed and entered florid D.I.C. (Disseminated Intravascular Coagulation). With fixed and dilated pupils, he was declared brain-dead.
Other Conditions Mentioned:
Fetal Parabiotic Tissue Mass: An abnormal fetal mass requiring RFA (radiofrequency ablation) to interrupt its blood supply.
Polyhydramnios: An excess of amniotic fluid, which was removed.
Self-Harm and Undiagnosed Pregnancy: Historical records showed a patient admitted for wrist lacerations who was discovered to be pregnant.
Episode 4: "Only Mama Knows"
Spinal Cord Ischemia (S.C.I.) Secondary to TEVAR Complication
Roy Secord experienced a catastrophic complication following a TEVAR procedure. The newly placed graft cut off the blood supply to his spine, causing spinal cord ischemia (S.C.I.) and paralysis. When other maneuvers failed, Dr. Pierce performed an audacious open-heart surgery, replacing the aorta with a Dacron graft and rebuilding the aneurysm sac into a "secondary aorta" to redirect blood flow back to the spinal cord.
Ruptured Abdominal Mass with Peritonitis
Nadia, a young girl, presented with a rigid abdomen, peritonitis, and hypotension. An ultrasound revealed a ruptured mass the size of a soccer ball, which was impinging on her left hepatic vein. During surgery, the mass caused a penetrating liver injury. Dr. Grey controlled the severe hemorrhage by employing a balloon tamponade using a Foley catheter, stabilizing the patient.
Other Conditions Mentioned:
TEVAR (Thoracic Endovascular Aortic Repair): The procedure that led to the S.C.I.
Balloon Tamponade: The emergency technique used to control Nadia's liver bleed.
Suicide Attempt: Referenced as a past critical event.
Episode 5: "Bend & Break"
Spinal Epilepsy Secondary to Brachial Plexus Avulsion Injury
Emily suffered comminuted radius and ulna fractures after her arm was caught in a noodle-making machine. Post-operatively, she experienced crippling "shocks" of pain. The final diagnosis was spinal epilepsy: the initial injury had ripped nerves from her spinal cord (brachial plexus avulsion), forming fluid-filled cysts that manifested as pain. The treatment was a neurosurgery using a radiofrequency probe to burn the nerve endings of her spine.
Metastatic Thyroid Carcinoma of the Proximal Femur
David Lasher (33), a thyroid cancer survivor, presented with hip pain. A PET scan confirmed bone metastasis to the proximal femur. A total hip replacement was ruled out dueto his compromised surgical bed. Instead, the team performed a complex staged reconstruction using a free vascularized fibular graft (taking bone and its native vessels from his lower leg) to span the defect, saving his leg.
Esophageal Atresia in a Neonate
Baby Lee Franklin was born with esophageal atresia with a long 4-centimeter gap, preventing a simple connection. Dr. Karev opted for a staged procedure: sutures were attached to both ends of the esophagus and threaded out of the baby's back. The sutures were pulled gently each day to stretch the ends toward each other for a later anastomosis, requiring the baby to be in a medically induced coma for weeks.
Other Conditions Mentioned:
Spinal Epilepsy: The rare condition causing debilitating shocks of pain.
Free vascularized fibular graft: The innovative orthopedic technique used to save David's leg.
Esophageal Atresia: The congenital defect where the esophagus is in two separate pieces.
Mild fetal hydrops: Fluid accumulation in a fetus, necessitating cardiac intervention.
Episode 6: "Don't Let's Start"
Early-Stage Esophageal Adenocarcinoma
Jeremy Weaver (42) presented with chest pain he insisted was heartburn. An EGD revealed the true cause: an early-stage adenocarcinoma (tumor) of the esophagus, caused by years of intense acid reflux. He was scheduled for an esophagectomy (replacing the esophagus with a piece of his colon). Tragically, during the operation, he developed a third-degree A.V. block, progressed to v-fib, and died on the table from cardiac arrest.
Other Conditions Mentioned:
Left Ventricular Hypertrophy (LVH): An incidental finding on Jeremy's EKG.
Hypercholesterolemia and Hypertriglyceridemia: High cholesterol and triglycerides found in Jeremy's labs.
Congenital Cystic Adenomatoid Malformation (CCAM): A fetal lung mass requiring fetal surgery.
Hydrops: Excessive fluid buildup in the fetus, caused by the CCAM.
Third-degree A.V. block: The complete heart block that led to the patient's death.
Episode 7: "Could We Start Again, Please?"
Placenta Percreta and Fetal Sacrococcygeal Teratoma (SCT)
The fetus of Emily Jensen was diagnosed with a Sacrococcygeal Teratoma (SCT) and was bleeding into the tumor, causing anemia. Dr. Robbins decided to perform a C-section to resect the tumor. During the delivery, pulling the placenta caused catastrophic hemorrhaging. The final diagnosis for the mother was Placenta Percreta, a severe condition where the placenta had invaded through the uterine wall and into her bowel, bladder, and kidney. The invasion was undetectable on prior imaging. Despite transfusing 100 units of blood, the mother died. The baby, however, was saved.
Other Conditions Mentioned:
Sacrococcygeal Teratoma (SCT): The fetal tumor that was bleeding.
Placenta Percreta: The fatal condition where the placenta invades other organs.
Fasciotomy: A surgical cut to relieve pressure in a patient's swollen leg.
Hemopneumothorax: Blood and air in the chest cavity of a trauma victim.
Episode 8: "Risk"
Descending Necrotizing Mediastinitis Complicated by Brain Abscess
Holly presented with a high fever after a root canal. She was diagnosed with Descending Necrotizing Mediastinitis (DNM), an infection that spread from her neck down into her mediastinum, causing sepsis. She was also found to have an abscess in her brain ventricle. Her airway closed, requiring an emergency cricothyrotomy. A surgical disagreement arose over which to treat first: the chest infection or the brain abscess. The chest debridement was performed first, revealing the infection had adhered to her ascending aorta.
Other Conditions Mentioned:
Cricothyrotomy: An emergency surgical airway.
Constrictive pericarditis: Inflammation that required stripping the entire pericardium.
Osteogenesis Imperfecta: A congenital "brittle bone" disease.
Episode 9: "Where Do We Go From Here?"
Insulinoma
Brooke James drove her car off a bridge with her two children. The incident was initially treated as an attempted murder-suicide. However, Brooke was unresponsive with a low D-Stick reading. Dr. Grey hypothesized the cause was related to the pancreas. The final diagnosis was an Insulinoma, a benign, insulin-secreting tumor. The resulting hypoglycemia caused cognitive deficits, confusion, and erratic behavior, explaining the accident. Dr. Grey located and surgically removed the tiny tumor.
Other Conditions Mentioned:
Duodenal Perforation: A hole in the duodenum.
Bucket-Handle Injury: A type of mesenteric injury where the mesentery is torn from the bowel.
Osteogenesis Imperfecta (OI): A fatal prenatal diagnosis for a fetus.
Episode 10: "The Bed's Too Big Without You"
Leiomyosarcoma of the Inferior Vena Cava (I.V.C.)
Adrian Nelson (51) was diagnosed with a leiomyosarcoma located behind her liver and including the Inferior Vena Cava (I.V.C.). During surgery, the tumor was found to be far more extensive than scans suggested, having spread to the diaphragm and pericardium. To visualize the complex resection, the team used 3-D printing to create a tangible model of the "cyclops" tumor. Using the 3D model in the OR, the surgeons were able to successfully dissect and remove the entire tumor.
Other Conditions Mentioned:
3-D printing: The technology used to create a model of the tumor for surgical planning.
Twin-to-Twin Transfusion Syndrome (T.T.T.S.): A complex fetal surgery case.
T.R.A.P. Sequence: A fetal abnormality requiring Radiofrequency Ablation (R.F.A.).
Massive Butterfly Glioma: A large, complex brain tumor on the optic nerve.
Hypoplastic Left Heart Syndrome (H.L.H.S.): A severe, "impossible" congenital heart defect case.
Episode 11: "All I Could Do Was Cry"
Type II Congenital Disorder (Patient: Samuel Norbert Avery)
April Kepner and Jackson Avery's baby was diagnosed with a fatal Type II congenital disorder, later identified as Osteogenesis Imperfecta Type II. The condition meant the baby's bones were breaking in utero. Given the fatal prognosis, the parents arranged for an induction termination. They delivered their son, Samuel Norbert Avery, who lived for 43 minutes.
Butterfly Glioma and Cortical Blindness
Drew Hawkins was admitted with total cortical blindness caused by a butterfly glioma in his optic radiation. Despite the tumor being "everywhere," Dr. Shepherd successfully removed 98% of it, extending his life. Post-operatively, Drew unexpectedly regained his sight.
Gunshot Wound with Migratory Pellet
Brenda Bonaman (44) presented with a shotgun wound to the neck. A major complication arose when she went into labor—an occult pregnancy. The strain of childbirth dislodged a pellet, which migrated into her heart's right ventricle, causing V-tach. She required immediate open-heart surgery.
Other Conditions Mentioned:
Osteogenesis Imperfecta Type II: The fatal "brittle bone" disease.
Induction Termination: The procedure chosen to deliver Samuel.
Butterfly Glioma: An aggressive brain tumor extending into both hemispheres.
Cortical Blindness: Blindness caused by brain lesions.
Migratory Pellet: The shotgun pellet that traveled to the patient's heart.
Episode 12: "The Great Pretender"
Splenomegaly Secondary to Unregulated Hormone Therapy
Curtis Warren ("Curt") (31), a transgender woman, presented post-syncope with "off the charts" liver enzymes and estrogen levels. A CT scan revealed massive splenomegaly (a swollen spleen) from a clot, which had caused gastric bleeds. The condition was linked to unauthorized, off-shelf hormone treatments. Treatment involved a splenectomy and a mandate to begin regulated hormone therapy and counseling.
Fall Injuries Resulting from Faked Syncope
Hillary List arrived unconscious after falling down concrete stairs. She later admitted she had faked fainting to avoid rejecting her boyfriend's proposal. The fall was real, however, and caused an artery under her skull to bleed, requiring brain surgery, as well as a knee fracture.
Other Conditions Mentioned:
Splenomegaly: The dangerously swollen spleen.
Faked Syncope: The feigned fainting that led to real injuries.
Narcolepsy and Cataplexy: Considered as differential diagnoses for fainting.
Episode 13: "Staring at the End"
Massive Grade IV Astrocytoma (Dr. Nicole Herman)
The season's central medical arc focused on Dr. Nicole Herman's massive Grade IV astrocytoma. The tumor was deeply enmeshed, touching nearly every brain structure. When it began to invade her optic chiasm, threatening her vision, Dr. Amelia Shepherd moved forward with an ambitious 18-hour surgery. The plan involved using fluorescein dye to delineate the tumor borders and placing radioactive seeds post-resection.
Fetal Teratoma Complicated by Hydrops Fetalis
Glenda Castillo's fetus was diagnosed with a large, vascular teratoma. The tumor progressed, causing early signs of hydrops fetalis (fluid accumulation) in the baby and severe hypertension and congestive heart failure (CHF) in Glenda. Dr. Herman was forced to perform an emergent procedure to embolize the vessels fetoscopically.
Other Conditions Mentioned:
Grade IV Astrocytoma: Dr. Herman's massive, invasive brain tumor.
Fluorescein dye: Used to make the tumor glow during surgery.
Radioactive seeds: Placed for post-resection radiation.
Hydrops Fetalis: A life-threatening accumulation of fluid in the fetus.
Vasa Previa: A high-risk obstetric condition that resulted in fetal death.
Episode 14: "The Distance"
Resection of a Large Brain Tumor and Subsequent Blindness
Dr. Nicole Herman underwent her 18-hour "whale surgery." Dr. Amelia Shepherd used a special dye to make the tumor glow. She successfully removed the entire tumor, clearing it from the fornix, thalamus, and hypothalamus. Radioactive seeds were placed. However, despite the "impossible" surgical success, the tumor's progression or the surgery itself resulted in a major neurological deficit: Dr. Herman was left completely blind.
Fetal Tumor and Maternal Mirror Syndrome
Glenda Castillo was admitted for fetal surgery. Her condition was complicated by a low platelet count and Mirror Syndrome, where her health declined as her baby's fetal anemia worsened. When embolization failed, Dr. Robbins performed an open procedure, exteriorizing the uterus to resect the tumor. The baby went into cardiac arrest in-utero but was resuscitated. Both mother and baby survived.
Other Conditions Mentioned:
Blindness: The post-operative outcome for Dr. Herman.
Mirror Syndrome: The rare condition linking the mother and baby's health.
Fetal Anemia: The condition of the baby with the teratoma.
Fetal Cardiac Arrest: The baby's heart stopped during the in-utero surgery.
Lacunar Infarct: A small stroke observed on post-op imaging.
Episode 15: "I Feel the Earth Move"
Tension Pneumothorax and Subdural Hematoma
An earthquake hit Seattle. An 11-year-old girl named Ruby called from a remote cabin, where her mother had fallen and was unconscious. Her lips were turning blue. Listening over the phone, doctors suspected a Tension Pneumothorax. Dr. Hunt guided Ruby through a field needle thoracotomy using a skewer and a straw to release the trapped air. Upon arrival at the hospital, the mother was also diagnosed with a Subdural Hematoma (SDH), which was surgically evacuated.
Grade IV Splenic Laceration
Micah (14) fell from a chair lift during the earthquake. He developed abdominal tenderness, and in the CT scanner, he crashed into V-fib. He was diagnosed with a Grade IV splenic laceration and a rupture. He was rushed to surgery for a splenectomy.
Below-the-Stem Femur Fracture
Jean Dominy (75) fell and sustained a below-the-stem femur fracture (periprosthetic fracture) distal to her 15-year-old hip replacement. Due to her high cardiac risk, she received a less invasive plating procedure instead of a full hardware replacement.
Other Conditions Mentioned:
Field needle thoracotomy: The decompression performed remotely using a skewer.
Periprosthetic Fracture: The fracture around her existing hip replacement.
Hypochondria: A behavioral diagnosis applied to an anxious patient.
Episode 16: "Don't Dream It's Over"
Normal Pressure Hydrocephalus (NPH) Masquerading as Alzheimer's
Martin Davis (65), the driver in a fatal car crash, was combative and disoriented, which his wife attributed to his Alzheimer's. He later experienced a dramatic return to lucidity. An MRI confirmed he actually had Normal Pressure Hydrocephalus (NPH), which mimics Alzheimer's symptoms. The car crash had torn the sheath around his spinal cord, temporarily releasing the fluid and his symptoms. Upon learning his NPH-induced dementia had caused a pregnant woman's death, he refused the shunt that would permanently cure him, choosing to regress into his dementia to forget the trauma.
Other Conditions Mentioned:
Normal Pressure Hydrocephalus (NPH): The "curable" dementia caused by CSF buildup.
Unstable Pelvis: A trauma injury requiring stabilization with a binder.
Shattered Pelvic Veins: The source of a persistent internal hemorrhage.
Extradural Hematoma (Epidural Hematoma): The diagnosis for the pregnant patient who died.
Episode 17: "With or Without You"
Ruptured Abdominal Aortic Aneurysm (AAA)
Evelyn Hunt, Owen's mother, was admitted after a fall. Her report of dizziness before the fall led to further investigation. Her condition deteriorated rapidly, and she was diagnosed with a Ruptured Abdominal Aortic Aneurysm (AAA); the earlier symptoms were a sentinel bleed. Her "lucky fall" got her to the hospital just in time for a successful repair.
Chronic Liver Disease and Cholangitis
Danny (17), a patient with a history of biliary atresia and chronic liver rejection, developed cholangitis. He insisted on a risky surgery to re-create his biliary tree. Dr. Grey attempted a hepatico-jejunostomy and placed a shunt, but the anastomosis leaked, and he died from complications.
Sinus Leeches
Andrea presented with a persistent headache and nosebleeds after a trip to China. Examination revealed the cause was not an infection, but a leech living in her sinuses, which Dr. Hunt successfully extracted.
Other Conditions Mentioned:
Biliary Atresia: Danny's underlying congenital condition.
Cholangitis: The acute infection of the bile duct.
Hepatico-jejunostomy: The high-risk procedure attempted on Danny.
Sinus Leeches: The parasitic "critter" found in Andrea's nose.
Autism: The focus of a neurosurgical research study on rats.
Episode 18: "When I Grow Up"
Multiple Gunshot Wounds Leading to Traumatic Brain Death and Organ Donation
Two police officers, Pete and Brett Gibson, were admitted with multiple GSWs.
Pete Gibson suffered a GSW to the trachea and multiple GSWs to the chest and abdomen. He suffered a traumatic arrest, and after 14 minutes, he was declared brain dead.
Brett Gibson also had GSWs to the neck and abdomen. He suffered a large stroke during surgery, which also resulted in brain death.
Jared (15), the suspect, was also admitted with GSWs and a completely avulsed liver, requiring an immediate transplant. Dr. Bailey convinced the officers' mother to make a directed donation of Brett's liver to Jared.
Other Conditions Mentioned:
GSW to the trachea: The specific injury requiring an emergency cricothyrotomy.
Traumatic arrest: Cardiac arrest caused directly by severe physical trauma.
Avulsed liver: The liver was torn away from its blood supply.
Directed donation: The organ donation from Brett to Jared.
Episode 19: "Crazy Love"
Spondylolisthesis/Severe Spinal Misalignment
Marissa McKay, a junior golfer, presented with severe lower back pain, dismissed as growing pains. X-rays revealed a severe spinal misalignment (spondylolisthesis). During surgery, a rod slipped, causing a complete loss of spinal cord function. Dr. Torres was called in for an emergency anterior stabilization, drilling through the sacrum to anchor L5 to S1. Her spine was realigned, but she would never play golf competitively again.
Traumatic Penile Amputation
Thomas Archibald, a chef, suffered a traumatic penile amputation inflicted by his wife. Dr. Catherine Avery was called in to perform the microvascular reattachment, which included using a saphenous vein graft to ensure profuse blood flow. The surgery was "impeccable," with a good prognosis for regaining function.
Other Conditions Mentioned:
Spondylolisthesis: The severe "zigzag" misalignment of the spine.
Phalloplasty: The surgical reattachment of the penis.
Saphenous vein graft: Used to provide blood flow to the neophallus.
Episode 20: "One Flight Down"
Acute Myocardial Infarction Complicated by Ventricular Rupture
A small plane crash brought in multiple victims. The pilot, Sam Garrett (36), reported chest pain before the crash. During surgery for his traumatic injuries (including intestinal tears and a splenectomy), he crashed into cardiogenic shock. He was diagnosed with an MI (heart attack) that had progressed to a ruptured ventricle and cardiac tamponade. Because he couldn't go on bypass, the team used cyanoacrylate (medical glue) to secure a patch over the rupture.
Post-Traumatic Amnesia
The passenger, Kate Shaw, suffered temporary memory loss (amnesia) after the crash. Hourly neuro checks were ordered to rule out a stroke or an evolving intracerebral contusion. Her memory eventually started to return.
Other Conditions Mentioned:
Cardiac Tamponade: Caused by the ruptured ventricle.
Cyanoacrylate (medical glue): The unconventional material used to patch the heart.
Placental Abruption: A concern for a pregnant patient at the scene.
Episode 21: "How to Save a Life"
Massive Blunt-Force Trauma and Fatal Secondary Brain Injury (Dr. Derek Shepherd)
Dr. Derek Shepherd was broadsided by a semi-truck after saving victims of another accident. He arrived at a non-trauma center with a flail chest and potential brain bleed. He was conscious enough to repeatedly advise the staff, "I need a head C.T." The staff, however, skipped the CT and rushed him to an exploratory laparotomy for a suspected abdominal bleed, where they found an avulsed colon. Following the surgery, his condition declined, and a blown right pupil confirmed a critical, missed intracranial bleed. The neurosurgeon on call arrived too late, and the delay resulted in a non-survivable brain injury. Meredith was called to terminate life-sustaining measures.
Other Conditions Mentioned:
Flail Chest: A segment of the chest wall moves independently, sustained by Derek.
Avulsed Colon: The large intestine was torn away.
Blown right pupil: The clinical sign of a critical brain bleed.
Non-survivable brain injury: The final diagnosis for Derek Shepherd.
Episode 22: "She's Leaving Home (Part 1)"
Complex Polytrauma and Spinal Fracture
Dan Pruitt, a police officer, was diagnosed with a fractured cervical spine and fractured legs after falling from a building. His treatment was exceptionally challenging, including complications like a breaking down abdominal graft. He became a candidate for a bionic prosthesis, and his rehabilitation, using neural-controlled sensors (implied to be Derek's research), was successful.
Extensive Full-Thickness Burns
Anne was admitted with extensive thermal injuries covering 60% of her TBSA from a house fire. Her treatment involved agonizing debridement of her burns layer by layer to promote new skin growth.
Fatal Traumatic Brain Injury (Dr. Derek Shepherd)
The episode dealt with the immediate aftermath of Dr. Derek Shepherd's death from his MVC accident, prompting widespread grief and discussions about living wills.
Other Conditions Mentioned:
Bionic prosthesis: The advanced, neural-controlled limb used by Dan Pruitt.
Debridement: The agonizing process of removing burned tissue.
Spinal Abscess: A dangerous collection of pus near the spinal column.
Episode 23: "She's Leaving Home (Part 2)"
Emergency Preservation and Resuscitation (EPR)
During a tunnel collapse, Scott Henry (17) presented with penetrating trauma and was losing blood faster than it could be replaced. Facing imminent death, Dr. Hunt proposed the highly experimental EPR protocol, or "suspended animation." This involved draining his blood and replacing it with cold saline to drop his core temperature to 50°F, "stopping time." This bought the surgeons 60-90 minutes to repair an infra-renal IVC injury. After the repair, he was warmed back up and successfully regained a heartbeat.
Other Conditions Mentioned:
Emergency Preservation and Resuscitation (EPR): The "suspended animation" protocol.
Induced hypothermia (50°F): The state required for EPR.
Infra-renal IVC injury: The critical vascular trauma repaired during EPR.
Cervical Spine Dislocation: A complication of a C5-C6 fracture.
Episode 24: "Time Stops"
Uterine Atony, Postpartum Hemorrhage, and Leaking Carotid Pseudoaneurysm
Joan, the fiancée of a trauma patient, was admitted with a C5-C6 fracture. After delivering her baby, she was diagnosed with uterine atony, which led to a severe postpartum hemorrhage (PPH), successfully treated with a balloon catheter. She then deteriorated, with dropping oxygen saturation. The new diagnosis was a leaking carotid pseudoaneurysm that was compressing her trachea. The pseudoaneurysm was surgically repaired with a patch.
Penetrating Thoraco-Abdominal Injury
Keith, a trauma victim, was impaled by a piece of his car door. He was bleeding out so rapidly (estimated 5-6 minutes to live) and all ORs were full, so the team performed an exploratory laparotomy while he was still in the car in the ER bay. This allowed them to clamp the bleeding vessels before a high-speed transfer to an OR.
Other Conditions Mentioned:
Uterine atony: The failure of the uterus to contract after childbirth, causing hemorrhage.
Postpartum hemorrhage (PPH): Severe bleeding after delivery.
Leaking carotid pseudoaneurysm: A contained rupture of the carotid artery.
Exploratory laparotomy (in a car): The radical field procedure to clamp bleeding.
🔖 Key Takeaways
The Inoperable Tumor: A central arc involved Dr. Herman's massive Grade IV astrocytoma. Dr. Amelia Shepherd's ambitious, 18-hour surgical plan to resect the tumor pushed the boundaries of neurosurgery, culminating in a miraculous outcome with a tragic, life-altering complication.
Pioneering New Technologies: The season showcased cutting-edge medical advancements. Dr. Torres's work on robotic prosthetics led to the use of Targeted Muscle Reinnervation (TMR) to help a veteran control a "six-million-dollar robot leg."
The Shocking Death of a Main Character: The season's most devastating medical event was the death of Dr. Derek Shepherd. His case was a tragic lesson in medical protocol, as a non-trauma center's failure to order a head CT led to a missed epidural bleed and a fatal, non-survivable brain injury.
Complex Fetal Medicine: The fetal surgery program featured prominently, highlighting high-risk cases like Placenta Percreta (resulting in a mother's death), a fetal Sacrococcygeal Teratoma (SCT), and the heartbreaking diagnosis of a fatal Type II congenital disorder for April and Jackson's baby.
Mass Casualty Events: The surgeons were tested by multiple mass casualty events, including a sinkhole collapse, an earthquake, a gas tanker pileup, and a catastrophic tunnel collapse, which led to the use of the experimental Emergency Preservation and Resuscitation (EPR) or "suspended animation" protocol.
