Popliteal Vein Tributaries

venae tributariae venae popliteae

The popliteal vein receives the small saphenous vein, the geniculate veins, and the anterior and posterior tibial veins as it courses through the popliteal fossa. The small saphenous vein joins the popliteal vein at a variable level above the popliteal crease — the saphenopopliteal junction, which is the primary target in small saphenous varicose vein treatment.

Clinical Notes

The saphenopopliteal junction anatomy is highly variable and must be mapped preoperatively with duplex ultrasound before small saphenous vein treatment. Popliteal vein thrombosis produces calf and popliteal pain, leg swelling, and carries significant risk of pulmonary embolism. The popliteal vein is compressed by popliteal artery aneurysm, Baker's cysts, and by tight knee bracing, producing deep venous obstruction. Endovenous ablation targets the saphenopopliteal junction for small saphenous reflux.

Saphenopopliteal Junction Incompetence

Reflux at the small saphenous-popliteal vein junction producing posterior calf varicosities, mapped by duplex ultrasound and treated by endovenous ablation or ligation at the junction.
