Complications of extremity vascular injuries in conflict.
BACKGROUND
The extremities remain the most common sites of wounding in conflict, are associated with a significant incidence of vascular trauma, and have a high complication rate (infection, secondary amputation, and graft thrombosis).


OBJECTIVE
The purpose of this study was to study the complication rate after extremity vascular injury. In particular, the aim was to analyze whether this was influenced by the presence or absence of a bony injury.


METHODS
A prospectively maintained trauma registry was retrospectively reviewed for all UK military casualties with extremity injuries (Abbreviated Injury Score >1) December 8, 2003 to May 12, 2008. Demographics and the details of their vascular injuries, management, and outcome were documented using the trauma audit and medical notes.


RESULTS
Thirty-four patients (34%)--37 limbs (30%)--had sustained a total of 38 vascular injuries. Twenty-eight limbs (22.6%) had an associated fracture, 9 (7.3%) did not. Twenty-nine limbs (23.4%) required immediate revascularization to preserve their limb: 16 limbs (13%) underwent an initial Damage Control procedure, and 13 limbs (10.5%) underwent Definitive Surgery. Overall, there were 25 limbs (20.2%) with complications. Twenty-two were in the 28 limbs with open fractures, 3 were in the 9 limbs without a fracture (p < 0.05). There was no significant difference in the complication rate with respect to upper versus lower limb and damage control versus definitive surgery.


CONCLUSIONS
We have demonstrated that prognosis is worse after military vascular trauma if there is an associated fracture, probably due to higher energy transfer and greater tissue damage.
