Cross-limb vascular shunting as an auxiliary to major limb revascularisation.

A 40-year-old male motorcyclist suffered a near-total amputation of his right foot. His limb was successfully salvaged with the aid of a cross-leg vascular shunt. Temporary arterial flow from the contralateral limb was transmitted via a pressure monitor tube to perfuse the avulsed part. This allowed the surgeon to carry out unhurried wound debridement, dissection of vital structures and skeletal fixation. The cannulation port was placed well distal to the proposed definitive anas<$>tomosis, to reduce damage to the endothelium. This procedure could be a valuable adjunct in major limb replantation, particularly in cases of prolonged ischaemia.
