Distal lower limb arterial reconstruction with modified allograft saphenous veins

Cadaveric donor saphenous veins subjected to proteolytic enzymatic digestion, crossbonding and heparin bonding were used for arterial reconstruction in the legs of 13 patients threatened with amputation and without suitable autogenous saphenous veins. Distal anastomoses were to the tibial and peroneal vessels. Twelve patients (92 per cent) were discharged from hospital with functioning grafts; 9 grafts (69 per cent) continue to function 2-16 (average 8) months after operation. Amputation was avoided in 11 patients (85 per cent). Although early results are encouraging, late results are yet to be determined.
