Bypass to the tibial and peroneal arteries using the great saphenous vein in situ.
In 22 patients with extensive atherosclerotic disease of the lower extremities 24 long bypasses have been performed. The main indications for surgery were rest pain and imminent or manifest gangrene. The semiclosed in situ vein technique was used in all except one case. Five grafts thrombosed within 2 weeks postoperatively, one of them was successfully reopened. At discharge 20 grafts were patent, and most of the patients had relief of their ischemic symptoms. After 5 years 26% of the long vein grafts were patent. In comparison, almost 70% of in situ femoro-popliteal vein grafts were patent. One patient is still living with an open long vein graft 14 years after surgery. The in situ vein technique is especially suited for long bypasses. The poorer results in the present series is probably due to an extremely advanced atherosclerotic disease and a high percent of small fibrotic veins with a diameter of 3 mm or less.
