The use of Y-shaped interposition vein grafts in multiple digit replantations.

Y-shaped vein grafts that have been specifically selected from the venous anatomy on the dorsum of the foot have been used to bridge the arterial defects in multiple digit replantations. In this technique, the two outflow limbs of the Y-shaped vein graft are anastomosed to the distal digital arteries of two adjacent fingers before osteosynthesis. The inflow stem of the Y-shaped graft is then anastomosed to a common digital artery or to the superficial palmar arch to provide rapid and reliable restoration of arterial inflow simultaneously into two adjacent digits.
