The impact of urgent computed tomography angiography for gunshot wounds in extremities with concomitant vascular injuries on diagnosis and postoperative outcomes

Abstract

Background and Objectives Computed tomography angiography represents one of the most important investigation modalities in the diagnosis and follow-up of vascular diseases. We prospectively compare between patients who have had preoperative computed tomography (CT) angiography and others who had not, to analyze the influence of CT angiography on the diagnosis and postoperative outcomes in gunshot cases. Methods A Cohort study to compare between patients who underwent preoperative CT angiography and others who had not, to analyze the influence of CT angiography on the diagnosis and postoperative outcomes in patients who suffer from urgent vascular reconstruction due to gunshot wounds in extremities with concomitant vascular injuries, in the time period from 17 February 2011 to 31 December 2011 in Al-Jalaa Hospital, Benghazi, Libya. Results During the study period, 89 patients were included, of whom 88 (99%) were males and 1 (1%) was female; the mean age was 29.5 years. Patients were arranged into two groups. The first group of 38 patients (43%) were operated urgently without preoperative CT angiographic evaluation. The second group of 51 patients (57%) have had a preoperative CT angiographic evaluation. Conclusion In the light of our study, we favor the immediate operative exploration of gunshot wounds in extremities with concomitant hard signs of vascular injuries without waiting for preoperative CT angiography, thereby minimizing the shock state and ischemic interval. CT angiography may be required for a more stable patient to avoid unnecessary surgical exploration.
