War injuries of the crural arteries.

Twenty-eight patients with military crural vascular injuries are presented. In the group undergoing immediate repair (21 patients), the time interval between trauma and surgery was 20 min to 30 h (mean 8 h 30 min). In those receiving delayed repair (seven patients), the interval between trauma and surgery was 3-47 (mean 14) days. Hyperbaric oxygenation therapy was used in conjunction with surgery and antibiotic therapy in 13 of the 28 patients. Explosive injuries were found in 14 patients and high-velocity missile injuries in nine; associated fractures were present in 20. Twenty of the 28 patients with crural vascular injuries had combined arterial and venous injuries, while eight had isolated arterial injuries. Twenty-five patients with distal ischaemia required arterial repair; five late amputations resulted. Military crural vascular injuries should be treated with soft tissue debridement, removal of foreign material, and microvascular arterial and concomitant vein reconstruction. This should be followed by external skeletal stabilization for bony and/or soft tissue instability, with fasciotomy for any associated compartment syndrome. The wound should be left open, with delayed closure or split skin grafting. It was felt that hyperbaric oxygen therapy reduced the amputation rate following combat-related crural vessel injuries.
