Risk Comparison

DVT Warning Signs

⚠️Unilateral leg swelling (one leg larger than the other)
⚠️Calf pain or tenderness, especially with walking
⚠️Warmth and redness over affected area
⚠️Visible surface veins
⚠️Pain worse when foot is flexed upward

PE Warning Signs (EMERGENCY)

🚨Sudden shortness of breath at rest or with minimal exertion
🚨Chest pain that worsens with deep breathing (pleuritic)
🚨Rapid heart rate (palpitations)
🚨Coughing up blood (hemoptysis)
🚨Feeling faint or lightheaded
🚨Sudden collapse - CALL 911 IMMEDIATELY

Prevention Strategies

Stay well hydrated - drink at least 8-10 glasses of water daily
Move regularly - avoid prolonged sitting or standing
Perform ankle circles and calf exercises, especially during long trips
Wear compression stockings during long flights or car trips

Important Medical Disclaimer

This calculator is for educational purposes only and should not replace professional medical advice. VTE risk assessment and thromboprophylaxis decisions should be made by your healthcare provider based on your complete medical history. If you experience any warning signs of DVT or PE, seek immediate medical attention.

Note: Pregnancy increases VTE risk 4-5 fold. Risk continues for 6-12 weeks postpartum. Always follow your provider's thromboprophylaxis recommendations.

What is VTE (Venous Thromboembolism) in Pregnancy?

Venous thromboembolism (VTE) encompasses deep vein thrombosis (DVT) and pulmonary embolism (PE). Pregnancy increases VTE risk 5-10 fold due to Virchow's triad: hypercoagulability, venous stasis, and vascular injury. VTE remains a leading cause of maternal mortality in developed countries.

🦵

Deep Vein Thrombosis (DVT)

Blood clot in a deep vein, usually in the leg. Can break loose and travel to the lungs causing PE.

🫁

Pulmonary Embolism (PE)

Life-threatening condition where clot blocks arteries in the lung. Medical emergency requiring immediate treatment.

When to Assess VTE Risk

📅

Booking Visit

First prenatal appointment to establish baseline risk and plan monitoring.

🏥

Hospital Admission

Any admission during pregnancy (hyperemesis, preterm labor, etc.).

👶

Post-Delivery

Postpartum period is highest risk. Reassess after cesarean or complications.
