Deep Venous Thrombosis (DVT) Explained | Risk Factors, Diagnosis & Treatment | CanadaQBank

Deep Venous Thrombosis (DVT) is a blood clot in the deep veins, usually of the legs—potentially life-threatening if it leads to pulmonary embolism (PE). But how do you recognize, diagnose, and manage it effectively? In this high-yield medicine video, we explain the pathophysiology, risk factors, clinical features, diagnosis, and management of DVT—perfect for USMLE, MCCQE, PLAB, and NCLEX exam preparation. What You’ll Learn in This Video: Definition: Formation of a thrombus in deep veins, commonly in the lower limbs (femoral, popliteal, or iliac veins). Pathophysiology: Virchow’s triad: Venous stasis, endothelial injury, and hypercoagulability. Risk Factors: Prolonged immobility, recent surgery, trauma, pregnancy, malignancy, oral contraceptives, obesity, thrombophilia (e.g., Factor V Leiden). Clinical Features: Unilateral leg swelling, pain, redness, and warmth. Homan’s sign (calf pain on dorsiflexion) may be present but is not reliable. Diagnosis: D-dimer: Screening test (high sensitivity, low specificity). Compression ultrasonography: Diagnostic test of choice. Venography: Gold standard (rarely needed). Management: Anticoagulation: Heparin → transition to DOACs or warfarin. Compression stockings to prevent post-thrombotic syndrome. IVC filter if anticoagulation contraindicated. Complications: Pulmonary embolism, post-thrombotic syndrome, recurrent DVT. High-Yield Pearl: “Unilateral leg swelling + risk factors = Think DVT until proven otherwise.” Perfect For: Medical students, residents, and healthcare professionals preparing for USMLE, MCCQE, PLAB, or NCLEX exams.
