Endovascular management of extra-cranial supra-aortic vascular injuries

Supra-aortic vessel injuries are uncommon but can be life-threatening and surgically challenging. Trauma to these vessels may be blunt or penetrating, including iatrogenic trauma following the insertion of central venous lines, which may be preventable. Recent advances in technology have resulted in endovascular therapy becoming a common first-line treatment, and interventional radiologists now play a major role in the management of these vascular injuries. We review the literature on the endovascular management of these types of injuries and describe a spectrum of case-based extra-cranial supra-aortic vascular injuries managed at our institution and the range of imaging appearances, including active contrast extravasation, traumatic vessel occlusion, true aneurysms, pseudoaneurysms, and arteriovenous fistulae.
