Value of multislice computed tomography angiography (MCTA) in neglected post traumatic vascular injuries of the extremities

摘要

Objectives To evaluate the role of MCTA in detecting neglected vascular injuries in the extremities. Study design This study included nineteen patients with previous trauma history, with clinically suspected vascular lesion. CTA was done for every patient and followed by surgical treatment. Results Out of the nineteen patients included, eighteen patients were accurately diagnosed by MCTA to have vascular lesions (94.7%), pseudoaneurysm in 10 (55.6%) patients, stenosis in 4 (22.2%) patients, AVF in 2 (11.1%) patients, and occlusion of an arterial segment in 2 (11.1%) patients. One patient (5%) had metallic artifact that alters image interpretation The accuracy of CTA in detecting vascular lesion in the examined patients was 94.7% with sensitivity and specificity of 94.4% and 100%, respectively. Conclusion MCT angiography is an initial accurate diagnostic method in evaluating patients with suspected neglected extremity trauma.
