Gastro: Budd-Chiari Syndrome: Free MSRA Podcast

⚕️FREE MSRA PODCAST –Budd-Chiari Syndrome🎧 A clear, high-yield breakdown of this hepatic vein outflow obstructionsyndrome – perfect for exam prep andreal-life clinical scenarios. 🧠Key Learning Points📌Definition• Budd-ChiariSyndrome (BCS) is a rare condition caused byobstruction of hepatic venous outflow, leading to liver congestion andimpaired function. The blockage may result from thrombosisor external compression.📌Causes & RiskFactors• Hypercoagulable states:Polycythaemia veraEssential thrombocythaemiaProtein C/S or antithrombin III deficiencyFactor V Leiden mutationAntiphospholipid syndromeParoxysmal nocturnal haemoglobinuria (PNH) • Other:Malignancies (e.g. HCC, renal cell carcinoma)Pregnancy, oral contraceptivesInfections (e.g. TB, amoebiasis)Congenital webs of the IVC💡 Mnemonic: "My Proliferation & Clotting Crew"📌Pathophysiology• Blocked hepaticveins → ↑ hepatic pressure• Liver congestionand swelling• Collateral vesselsdevelop but often insufficient• Chronic damage →fibrosis → cirrhosis📌Symptoms• Classic triad:Sudden abdominal painAscitesTender hepatomegaly• Also: jaundice, oedema, dilated abdominal veins, splenomegaly, encephalopathy💡 Mnemonic: "ACHES": Ascites, Congestion, Hepatomegaly, Encephalopathy, Splenomegaly📌DifferentialDiagnosis• Cirrhosis• Portal veinthrombosis• Right heartfailure• Constrictivepericarditis• Hepaticveno-occlusive disease (post-BMT)• Infections (e.g.CMV, TB), autoimmune liver diseases📌Diagnosis• Doppler ultrasound – first-line, detects absentor reversed hepatic flow• MRI/CT with contrast – detailed imaging ofhepatic vasculature• Liver biopsy – shows central lobular congestion• Blood tests – LFTs (mild ↑), clotting profile,thrombophilia screen💡Clue: Prominentcaudate lobe + reversed flow on Doppler📌Management• Anticoagulation – lifelong in many cases• Thrombolysis – if clot is acute and accessible• Angioplasty ± stent – to open narrowed veins• TIPS (Transjugular Intrahepatic Portosystemic Shunt)– to relieve portal pressure• Liver transplant – for decompensated liverdisease• Symptomatic care – diuretics, fluidrestriction, low salt for ascites📌Complications• Liver failure• Portalhypertension• Variceal bleeding• Hepatorenalsyndrome• Spontaneousbacterial peritonitis (SBP)📌Prognosis• Depends on stageat diagnosis, underlying cause, and response to treatment• Good prognosiswith early diagnosis and effective management• 5-year survivalcan exceed 90% if treated appropriately 📎More MSRA Resourcesfor Budd-Chiari Syndrome📝 Revision Notes: https://www.passthemsra.com/topic/budd-chiari-syndrome-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/budd-chiari-syndrome-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/budd-chiari-syndrome-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/budd-chiari-syndrome-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/gastroenterology-for-the-msra/ Hashtags#MSRA #MSRARevision#MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes#MSRAAccordions #MultiSpecialtyRecruitmentAssessment #MSRAOnlineRevision#MSRARevisionWebsite #BuddChiariSyndrome
