Head and neck neurovascular trauma: Clinical and angiographic correlation

Abstract

A retrospective review of all angiograms done for craniocervical trauma, over an eight-year period at Groote Schuur Hospital identified 61 patients out of 823 angiographically studied who had extradural vascular injury and required endovascular treatment. Multiple lesions were identified in nine (14,8%) patients and associated injuries were found in 23 patients (37%). The mechanism of injury was blunt in nine (14.8%) patients and penetrating in 52 (85.2%). There was a statistically significant correlation between the presenting clinical feature and the underlying angiographic lesion. Patients with active bleeding were more likely to have a vessel laceration, an expanding hematoma was associated with false aneurysm and a pulsatile mass with arteriovenous fistula. Endovascular treatment with emphasis on vessel occlusion rather than preservation was successful in all cases except one which required surgical vessel ligation.
