Deep Vein Thrombosis (DVT) is a serious vascular condition where a blood clot (thrombus) forms in the deep veins, usually in the legs. If untreated, the clot can dislodge and travel to the lungs, causing a life-threatening pulmonary embolism (PE).
Incidence
- More common in hospitalized, immobile, and post-surgical patients.
- High risk in pregnancy, obesity, and smokers.
- Annual incidence: ~1 in 1,000 people.
Definition
DVT is the formation of a blood clot in a deep vein, often in the legs or pelvis, leading to pain, swelling, and risk of embolization.
Etiology (Causes & Risk Factors)
1. Virchow’s Triad (Mnemonic: "VIS")
- V – Venous Stasis (Prolonged immobility, bed rest, travel).
- I – Injury to Vessel Wall (Surgery, trauma, IV catheters).
- S – State of Hypercoagulability (Cancer, pregnancy, smoking).
2. Risk Factors (Mnemonic: "THROMBOSIS")
- T – Trauma or surgery.
- H – Hormonal therapy (Birth control, pregnancy).
- R – Reduced mobility (Paralysis, long flights).
- O – Obesity.
- M – Malignancy (Cancer-associated hypercoagulability).
- B – Blood disorders (Factor V Leiden, Protein C/S deficiency).
- O – Old age (>60 years).
- S – Smoking.
- I – Infections or inflammatory conditions.
- S – Stroke or previous DVT history.
Pathophysiology of DVT (Mnemonic: "CLOT")
- C – Coagulation cascade activation leads to fibrin clot formation.
- L – Loss of blood flow (stasis) promotes clot development.
- O – Obstruction of venous return causes leg swelling & pain.
- T – Thrombus can embolize → Pulmonary Embolism (PE).
Clinical Features (Mnemonic: "CLOTS")
- C – Calf pain & swelling (unilateral).
- L – Localized warmth & redness.
- O – Obstruction of venous return → Heavy feeling in leg.
- T – Tenderness along the deep vein.
- S – Sudden breathlessness → Suspect Pulmonary Embolism (PE).
Signs of DVT
- Homan’s Sign – Calf pain on dorsiflexion of the foot.
- Pratt’s Sign – Tenderness on squeezing the calf.
Complications
- Pulmonary Embolism (PE) – Clot breaks off and blocks lung arteries.
- Post-Thrombotic Syndrome (PTS) – Chronic leg pain & swelling.
- Venous Ulcers – Due to poor circulation.
Laboratory Investigations
1. Blood Tests
- D-dimer test – High levels indicate clot breakdown (Sensitive but not specific).
- Coagulation Studies (PT, APTT, INR) – Check for clotting disorders.
2. Imaging
- Doppler Ultrasound (Gold Standard) – Detects vein blockage.
- Venography – Most accurate but invasive.
- CT Pulmonary Angiography (CTPA) – If PE is suspected.
Management of DVT
General Measures (Mnemonic: "WALK")
- W – Wear compression stockings.
- A – Avoid prolonged sitting or standing.
- L – Leg elevation to improve circulation.
- K – Keep moving (Early mobilization after surgery).
Allopathic Treatment (Mnemonic: "ABCs of DVT")
- A – Anticoagulants (Heparin, Warfarin, Rivaroxaban).
- B – Blood thinners (Low molecular weight heparin – LMWH).
- C – Clot busters (Thrombolytics – Alteplase, Streptokinase) in severe cases.
Surgical Treatment
- Inferior Vena Cava (IVC) Filter – Used if anticoagulation is contraindicated.
- Thrombectomy – Surgical removal of clot (Rarely needed).
Homeopathic Treatment
5 Homeopathic Medicines with Symptoms
1. Hamamelis Virginiana
- Engorged, painful veins with bruised sensation.
- Varicose veins with burning pain.

3. Vipera Berus
- Severe pain and swelling of veins.
- Leg feels as if it will burst.
- Relieved by keeping legs elevated.
- Bluish, swollen veins with extreme tenderness.
- Effective in deep vein thrombosis with risk of gangrene.
4. Arnica Montana
- Painful swelling due to trauma or surgery.
- Bruised, sore feeling in limbs.
- Worse from touch, better with rest.
- Prevents clot formation after injury.
- Useful in preventing post-surgical thrombosis.
5. Fluoricum Acidum
- Varicose veins with ulceration.
- Burning pain, worse in warmth.
- Weak veins that rupture easily.
- History of venous insufficiency and clot formation.
- Useful in chronic venous congestion.
