Haem: Post-Thrombotic Syndrome: Free MSRA Podcast

🎧Post-ThromboticSyndrome – Long-Term Leg Complications After DVT 🦵💥Welcome to anotherfocused MSRA Deep Dive — today we’re tackling Post-ThromboticSyndrome (PTS). If you've ever wondered why leg pain, swelling, or skinchanges persist long after a DVT, this episode is essential. We're breakingdown the why, who, how, and what to do — so whether you’re revising forthe MSRA or want clarity on a complexvascular issue, this is for you.🧠What You’ll Learn:• Definition: – PTS is a chronic condition that can develop after a DVT – Caused by long-term damage to vein valves and walls →leads to chronic venous hypertension• Pathophysiology: – Residual clot +inflammation damages valves – Leads to venous reflux, venoushypertension, and tissue hypoxia – Over time →capillary leakage, swelling, skin changes, fibrosis• Key Risk Factors: – Older age, obesity,recurrent DVTs – Inadequate ordelayed anticoagulation – Thrombophilia,cancer, prolonged immobility (flights, bed rest) – DVT in proximal veins (e.g. femoral, iliac) = higherPTS risk🩺Clinical Features:• Symptoms: – Chronic leg pain,swelling, heaviness – Worse at end ofday / with standing – Improved with leg elevation – Cramps, fatiguein the limb• Signs: – Hyperpigmentation, lipodermatosclerosis (woody skin texture) – Varicose veins, venouseczema, venous ulcers in severecases – Skin itching(pruritus)📊Investigations:• History & Examination: – Ask aboutprevious DVT – Look forpersistent swelling, skin changes, varicosities• Duplex Ultrasound: – Confirms venous reflux, residualthrombus, or valve dysfunction – Main non-invasivetool for diagnosis• Advanced Imaging (if needed): – Venography, MRvenography if considering interventions📍UK Epidemiology: – Affects up to 20–50% of patients post-DVT – Significant causeof long-term morbidity💊Management:• Conservative First-Line: – Compression therapy (graduated stockings) – Leg elevation, regularwalking – Weight loss,optimise cardiovascular risk factors• Important Guideline Note: – Stockings are not routinely recommended for preventingPTS post-DVT – But they are recommended for treatment once PTS isdiagnosed• Severe Cases: – Endovascular stenting or angioplasty for obstruction – Rarely: open veinsurgery – Ulcer management with dedicated wound careservices📈Prognosis:• Varies widely —early recognition + compression helps symptom control• Often chronic, butmanageable with consistent therapy• In severe cases,can impair mobility and quality of life• Ulcers can becomerecurrent, infected, or non-healing⚠️Complications:• Venous ulcers (persistent, painful, slow toheal)• Recurrent DVT• Chronic pain, mobility issues• Pulmonary embolism if new clots form• Psychosocial impact due to reduced activity +visible leg changes📚Memory Aids:• Think: “Post-DVT→ Persistent Damage”• Pain + Pigment + Puffiness = classic triad• Elevation helps → suggests venous cause• Ultrasound is key for diagnosis📝Revision Resources:• 📘 Revision Notes:https://www.passthemsra.com/topic/post-thrombotic-syndrome-revision-notes/• 🃏 Flashcards:https://www.passthemsra.com/topic/post-thrombotic-syndrome-flashcards/• 📂 Accordion Q&A Notes:https://www.passthemsra.com/topic/post-thrombotic-syndrome-accordion-qa-notes/• 🎯 Rapid Quiz:https://www.passthemsra.com/topic/post-thrombotic-syndrome-rapid-quiz/• 🧪 Practice Quiz:https://www.passthemsra.com/quizzes/post-thrombotic-syndrome/🌐Main Sites:https://www.passthemsra.comhttps://www.freemsra.com#MSRA#PostThromboticSyndrome #PTS #DeepVeinThrombosis #DVTComplications#MSRAFlashcards #Haematology #VenousHypertension #MSRARevision #PassTheMSRA#FreeMSRA #CompressionTherapy #VenousUlcers #MedicalPodcast #MSRAQuestionBank
