Deep Vein Thrombosis (DVT) refers to the formation of a blood clot (thrombus) within a deep vein, most commonly in the lower extremities (legs, thighs, or pelvis). It is a potentially serious condition as the clot may dislodge and lead to pulmonary embolism (PE).
๐๐ฉ๐๐ค๐ก๐ค๐๐ฎ (๐พ๐๐ช๐จ๐๐จ)
DVT commonly occurs due to Virchowโs Triad:
-Venous stasis โ e.g., immobility, prolonged bed rest, long flights/travel
-Endothelial injury โ e.g., surgery, trauma, inflammation
-Hypercoagulability โ e.g., genetic clotting disorders, pregnancy, malignancy, hormone therapy
๐๐๐จ๐ ๐๐๐๐ฉ๐ค๐ง๐จ
-Surgery (especially orthopedic or pelvic)
-Prolonged immobilization
-Pregnancy and postpartum period
-Oral contraceptives or hormone replacement therapy
-Cancer
-Obesity
-Smoking
-Age > 60
-Previous history of DVT or PE
-Inherited thrombophilias (e.g., Factor V Leiden)
๐๐๐ฉ๐๐ค๐ฅ๐๐ฎ๐จ๐๐ค๐ก๐ค๐๐ฎ
-Blood flow slows or becomes turbulent (venous stasis)
-Injury to the endothelium initiates platelet aggregation and clotting cascade
-A thrombus forms, obstructing venous return
-Risk of thrombus dislodging and migrating to lungs (PE)
๐พ๐ก๐๐ฃ๐๐๐๐ก ๐๐๐๐ฉ๐ช๐ง๐๐จ
-Unilateral leg swelling (calf or thigh)
-Pain or tenderness in the affected limb (especially on palpation)
-Redness and warmth over the area
-Dilated superficial veins
-Positive Homanโs sign (pain in calf with dorsiflexion of the foot) โ not specific
-Often asymptomatic in early stages
๐๐ฃ๐ซ๐๐จ๐ฉ๐๐๐๐ฉ๐๐ค๐ฃ๐จ
1) D-Dimer Test
-Elevated in DVT but non-specific
2) Doppler Ultrasonography (Venous Duplex Scan)
-Most common diagnostic test
3) Venography (Contrast X-ray)
-Gold standard, but rarely used now
4) Blood coagulation profile โ To detect clotting disorders
5) CT Pulmonary Angiogram (CTPA) โ If PE is suspected
๐พ๐ค๐ข๐ฅ๐ก๐๐๐๐ฉ๐๐ค๐ฃ๐จ
โขPulmonary Embolism (PE) โ Life-threatening condition
โขPost-thrombotic syndrome (PTS) โ Chronic pain, swelling, skin changes
โขChronic venous insufficiency
โขRecurrent DVT
๐๐๐ฃ๐๐๐๐ข๐๐ฃ๐ฉ
โขMedical
1) Anticoagulation: Heparin, Low Molecular Weight Heparin (LMWH), Warfarin, DOACs (Apixaban, Rivaroxaban)
2) Thrombolytic therapy (in severe cases)
3) Inferior Vena Cava (IVC) filter โ If anticoagulation is contraindicated
โขSurgical
1) Thrombectomy โ Rarely performed, in severe cases
๐๐๐ฎ๐จ๐๐ค๐ฉ๐๐๐ง๐๐ฅ๐ฎ ๐๐ค๐ก๐ ๐๐ฃ ๐ฟ๐๐
โ Contraindicated: Mobilization or massage in acute undiagnosed DVT phase due to risk of embolization

1)Early Mobilization (when safe)
-Enhances venous return and prevents complications
2) Graduated Compression Stockings
-Prevents PTS and reduces swelling
3) Limb Elevation
-Reduces edema
4) Breathing Exercises
-Prevents PE and improves lung perfusion
5) Ankle Pumping and ROM exercises
-Enhances circulation in immobilized patients
6) Education
-Avoid prolonged immobility
-Encourage hydration
-Lifestyle changes: exercise, smoking cessation
๐๐ง๐๐ซ๐๐ฃ๐ฉ๐๐ค๐ฃ
-Early ambulation post-surgery
-Use of compression stockings or intermittent pneumatic compression (IPC) devices
-Anticoagulant prophylaxis in high-risk individuals
-Leg exercises during long travel
-Avoiding dehydration
๐๐๐ฎ ๐๐ค๐๐ฃ๐ฉ๐จ
-DVT is a medical emergency with risk of pulmonary embolism
-Prompt diagnosis and appropriate anticoagulation are critical
-Physiotherapists must screen carefully before initiating mobilization
-Patient education is essential in both prevention and rehabilitation...
