🤱 Postpartum Deep Vein Thrombosis Risk Simulator

Pregnancy Hypercoagulability

Placeholder: pregnancy shifts hemostasis toward clotting readiness.

• ↑↑: Factor VIII/fibrinogen (Placeholder short note)
• ↓: Protein S (Placeholder short note)
• ↑: Venous stasis (uterus) (Placeholder short note)
• 5x: Baseline VTE risk (Placeholder short note)

Why pregnancy is prothrombotic

Placeholder: evolutionary bleeding protection at delivery raises clot risk.

Cesarean Delivery Adds Thrombosis Risk

Placeholder: surgery, vessel injury, and immobility compound baseline risk.

• 2-4x: C-section vs vaginal (Placeholder short note)
• Present: Vessel wall injury (Placeholder short note)
• Hours: Post-op immobility (Placeholder short note)
• Higher: Emergency vs elective (Placeholder short note)

Surgical contribution to Virchow triad

Placeholder: endothelial injury plus stasis plus hypercoagulability converge.

Immobilization and Venous Stasis

Placeholder: reduced calf muscle pump slows venous return sharply.

• ↑ risk: Bed rest duration (Placeholder short note)
• Inactive: Calf muscle pump (Placeholder short note)
• ↑: Valve pocket pooling (Placeholder short note)
• ↓↓: Flow velocity (Placeholder short note)

Stasis as the clot nucleation trigger

Placeholder: pooled blood near valve cusps favors clot initiation.

Age, Obesity and Compounding Risk

Placeholder: additional factors stack multiplicatively on baseline risk.

• +risk: Age >35 (Placeholder short note)
• +risk: Obesity (BMI>30) (Placeholder short note)
• +risk: Prior VTE/thrombophilia (Placeholder short note)
• +risk: Multiple gestation (Placeholder short note)

Cumulative risk scoring

Placeholder: risk factor counts guide prophylaxis decision scoring.

Prevention — Ambulation, Compression, Anticoagulation

Placeholder: early mobilization and stockings restore normal venous flow.

• Effective: Early ambulation (Placeholder short note)
• Effective: Compression stockings (Placeholder short note)
• High risk cases: LMWH prophylaxis (Placeholder short note)
• ~65%: Risk reduction (Placeholder short note)

Combining prophylaxis measures

Placeholder: mechanical plus pharmacologic prophylaxis lowers DVT incidence.

Placeholder: early walking after delivery is the simplest effective prevention.
