🎙️ MSRA Podcast: Extradural Haematoma (EDH) – The Pressure Problem You Can't MissWelcome to The Deep Dive – your go-to for cutting through revision noise. Today, we’re zeroing in on Extradural Haematoma (EDH) – a trauma-linked neurosurgical emergency that's high-yield for MSRA and critical in real-world medicine.🧠 What Is Extradural Haematoma?• Blood collects between the skull and dura mater, often after trauma• Classically caused by rupture of the middle meningeal artery (MMA)• Classic CT appearance: biconvex/lens-shaped haematoma• Rapidly expands → raises intracranial pressure🧠 Mnemonic: “Skull-Dura = EDH” and “Pressure Problem”💥 Common Causes• Head trauma: falls, RTCs, assaults• Temporal/parietal skull fractures → injury to MMA• Dural sinus tears or diploic vessels also possible• In kids: less likely to have skull fracture due to pliable bones• Spinal EDH: procedures (epidurals), clotting issues, spontaneous bleeds⚠️ Risk Factors• Trauma, contact sports, coagulopathy• Anticoagulant use• Age extremes (older = fragile vessels; children = flexible skulls)📉 Pathophysiology• Bleeding into a tightly limited space• Dura sticks to skull – blood can't spread easily• Compresses brain → neurological deterioration• Lucid interval may occur but is not always present🩺 Clinical Features• Headache, vomiting, drowsiness• Seizures, focal neurology (e.g., limb weakness)• Unequal pupils (CN III palsy), bradycardia + hypertension (Cushing’s response)• Red flags: rapid deterioration, signs of raised ICP, post-trauma neuro decline• Spinal EDH: cord signs like incontinence or limb weakness🧪 Investigations• Non-contrast CT head: gold standard (shows lens-shaped bleed)• Bloods: FBC, U&Es, clotting profile, group & save• MRI for chronic/unclear cases or spinal EDH❌ Do NOT perform lumbar puncture if raised ICP is suspected🧰 Management Overview🔹 Stabilise first: ABCs, neck precautions, IV fluids🔹 Surgical evacuation: craniotomy or burr holes🔹 Indications for surgery:• >30cc haematoma• Any neuro signs• GCS < 9🔹 Medical options (if mild): close observation, repeat imaging🔹 ICP management: mannitol, hypertonic saline, head elevation🔹 Post-op care: monitor for seizures, complications, neurological rehab🧠 Anticoagulants? Hold. Seizures? Risk remains.📊 Epidemiology (UK)• Incidence: ~4 per 100,000/year• Male:female ratio ~4:1• Peak: teens (11–16), but prognosis worse in elderly• ~2% of all head injuries; 5–15% of fatal cases📈 Prognosis• Excellent if treated early• Mortality: ~5–30% overall• Predictors of poor outcome: older age, large bleed, delayed surgery, low GCS• Risk of post-traumatic seizures (esp. in alcohol misuse)• Delayed complications: post-concussion syndrome, spasticity, neuropathic pain📚 Extradural Haematoma MSRA Revision Resources📝 Revision Notes:https://www.passthemsra.com/topic/extradural-hematoma-revision-notes/🃏 Flashcards:https://www.passthemsra.com/topic/extradural-hematoma-flashcards/📖 Accordion Q&A Notes:https://www.passthemsra.com/topic/extradural-hematoma-accordion-qa-notes/🧠 Rapid Quiz:https://www.passthemsra.com/topic/extradural-hematoma-rapid-quiz/📊 Practice Quiz:https://www.passthemsra.com/quizzes/extradural-haematoma/🎧 Revision Pearl“Trauma + brief recovery + decline = Think EDH. CT now. Pressure kills.”Remember: MMA + lens-shaped bleed + early surgery = survival.Explore more top-tier MSRA revision tools at:🌐 https://www.passthemsra.com🌐 https://www.freemssra.com#MSRA #ExtraduralHaematoma #EDH #TraumaCT #Neurosurgery #MSRAFlashcards #MSRAQuiz #PassTheMSRA #MSRARevisionNotes #BrainBleed #LucidInterval #GPExamPrep #MedicalPodcast #DeepDivePodcast
