Abstract
The Vascular Unit at Suez Canal University Hospital in Egypt covers a wide area with high rates of severe injuries. This is a prospective study of mangled extremities to identify risk factors associated with limb loss in these patients. Between December 2000 and August 2003, a prospective study on all patients with arterial injuries in mangled extremities was undertaken. All patients were scored using the Mangled Extremity Severity Score (MESS) and the Mangled Extremity Severity Index (MESI). During this period, arterial reconstruction was performed in 62 patients. Primary patency, secondary patency, and limb salvage rates were 81%, 85.5%, and 93.5%, respectively. The only factor affecting limb salvage (statistical trend) was the site of trauma (upper limb 100% vs lower limb 89%; p = .08%). There was no significant effect related to the mechanism of trauma (blunt 90% vs stab 100%; p = .125), MESS (< 7, 100% vs > 7, 91%; p = .22), and MESI (< 20, 100% vs > 20, 90.5%; p = .154). Upper limb injuries were the least likely to lead to amputation. We recommend that all injuries, whatever their score, should be surgically explored before treatment decisions are made.
