Brachial artery reconstruction using the heparin-bonded Sundt shunt.

Fracture stabilization is often desirable prior to vascular repair in the management of major extremity injuries. This principle is particularly important when long vein grafts are required to minimize the risk of anastomotic disruption during the orthopedic portion of the procedure. However, in situations associated with prolonged periods of preoperative ischemia, early reperfusion of the injured extremity would be optimal. This report illustrates two cases of brachial artery injury in which heparin-bonded shunts were used to establish blood flow to the distal extremity before fracture fixation. The shunts were interposed between disrupted arterial segments and reestablished distal perfusion while associated fractures were internally stabilized. Thus, early revascularization allowed the orthopedic repair to proceed in an unhurried fashion. After adequate stabilization of the fracture, arterial reconstruction was completed using saphenous vein interposition grafts. This technique potentially could improve extremity salvage rates and facilitate the repair of arterial injuries associated with unstable long bone fractures.
