CPT® Code 37760

The procedure described by CPT® Code 37760 involves the ligation of perforator veins, specifically utilizing a radical Linton-type technique. Perforator veins are critical structures that connect the deep venous system, which includes the femoral and popliteal veins, to the superficial saphenous veins in the legs. This procedure is primarily indicated for patients suffering from severe chronic venous insufficiency, a condition characterized by the improper functioning of the veins, leading to symptoms such as swelling, pain, and the formation of venous ulcers. The ligation aims to treat incompetent perforator veins, which contribute to the backward flow of blood and exacerbate venous insufficiency. During the procedure, an open surgical approach is employed, which involves making a long hockey stick incision along the medial aspect of the calf, extending posteriorly to the medial malleolus. This incision allows for the development of subfascial skin flaps, enabling the surgeon to access and ligate the perforator veins effectively. The ligation interrupts the abnormal blood flow between the deep and superficial venous systems, thereby alleviating the symptoms associated with chronic venous insufficiency. If necessary, a skin graft may be applied to cover any defects created during the procedure, which involves harvesting skin from a separate donor site and suturing it over the defect. This comprehensive approach ensures that the underlying venous issues are addressed while also managing any resultant skin defects from the surgical intervention.
