Minimally invasive surgery incisions for varicose veins in the calf are mainly based on the varicose vein, with varicose saphenous veins being located on the anterior medial side and varicose saphenous veins on the posterior side. Calf varicose veins are mainly varicose saphenous veins or small saphenous veins in the calf, so the minimally invasive surgical incision is mainly based on the location of the varicose veins. The course of the great saphenous vein starts on the medial side of the dorsal venous arch of the foot and travels through the anterior aspect of the inner ankle and up the medial side of the calf into the medial side of the thigh. Therefore, when the saphenous vein is varicose in the calf, the minimally invasive surgical incision is usually made in the medial aspect of the calf. The course of the small saphenous vein starts on the lateral aspect of the dorsal venous arch of the foot and travels upward through the posterior aspect of the ankle to the posterior aspect of the calf into the thigh. Therefore, when the small saphenous vein in the calf is varicose, the minimally invasive incision is usually made at the back of the calf.
