BACKGROUND: The start of the armed conflicts in Libyan society in 2011 led to a dramatic increase in the incidences of unusual types of brachial artery injuries, which were previously uncommon. In this study, the postoperative outcomes have been compared prospectively between patients who have had injuries at the proximal anatomical half of the brachial artery with those who suffered injuries at the distal anatomical halfMETHODS: A cohort study was undertaken to compare patients who had an injury at the proximal anatomical half of the brachial artery (considered as the first group) and patients who had an injury at the distal anatomical half of the brachial artery (considered as the second group). This was undertaken to analyse the influence of the anatomical site of injury on the postoperative outcomes in patients who underwent urgent surgical repair procedures at the hospital from February 2011 to December 2016RESULTS: Out of fifty-one patients, 31 (60.8%) patients had gunshot injuries, 12 (23.5%) had explosive injuries, four (7.8%) had stab wounds and four (7.8%) were victims of road traffic accidents. There were 13 (25.5%) patients in the first group and 38 (74.5%) patients in the second group. Three patients (5.9%) had postoperative arterial occlusion due to thrombosis, while two (3.9%) had postoperative graft occlusion due to thrombosis; the other two (3.9%) had compartment syndromeCONCLUSION: Based on the anatomical background, critical limb ischaemia and postoperative ischaemic complications, as well as delayed limb amputation, are more associated with the injuries to the proximal anatomical half of the brachial artery due to poor collateral circulation at this level

Keywords : brachial artery; gunshot injury; arterial repair; limb ischaemia; venous graft.
