Thromboembolism after pelvic surgery is usually from the veins -
• MC site of DVT: Calf veins (soleal veins)
• MC site thrombosis for pulmonary thromboembolism: Femoropopliteal veins
• Calf veins are the most common site of DVT in post-operative period, but risk of embolism from calf venous thrombosis is extremely low.
• DVT of femoropopliteal veins are the most common site of pulmonary thromboembolism.
