In Situ Vein Bypass for Limb Salvage
(608) 265-4420 or
In situ vein bypass is one of the methods used for revascularization of lower extremities to avoid amputation. This method has been under development since the 1950s. Many surgeons abandoned the procedure due to early failures; however, new methods in valve disruption prompted renewed interest in this limb-saving procedure.
In 1981, Dr. Charles Acher introduced the retrograde valve disruption technique at the University of Wisconsin using the Hall Valvulatome. This has led to improved patency and limb salvage rates.
With experience in more than 400 patients with limb-threatening ischemia, the limb salvage and secondary patency rates are 90% at six years for femoral popliteal bypasses.
These improved limb salvage rates allow more independent living and improve life quality for patients with severe limb-threatening vascular disease.
