| Abstract: | Traumatic vessel injury can cause bleeding, thrombosis, embolization, or malperfusion due to external compression and spasm. Non-traumatic causes of acute large arterial emergencies include rupture of an aneurysm and pseudoaneurysm, dissection, embolization, and thrombosis in hypercoagulability syndromes. Ultrasonography is, of course, the imaging modality of choice in emergency cases; however, in central vascular injuries, spiral CT with contrast enhancement is the imaging modality that provides the most information. Angiography may be necessary for detailed information and before intervention. Stent-grafts are used to close large vascular lacerations, ruptured aortic aneurysms, and the entry tear of dissections. Interventional radiology methods play a major role in managing vascular emergencies. [ABSTRACT FROM AUTHOR] |
