Surgical approaches to vertebral artery injuries

Twenty patients with penetrating injuries of the vertebral artery who were treated as emergencies were subjected to the following operative approaches: five cases, Henry's approach (posterior) and modified Henry's approach (anterior); five cases, limited exposure and application of metal clips; four cases, plugging of the arterial defect with Oxycell or crushed muscle; three cases, control with ligatures and non‐conventional exposure of the artery; one case, inflation of a balloon catheter within the vertebral canal; one case, repair of the lacerated first extraosseous part of the vertebral artery. One patient died from exsanguination on the operating table, before any repair was possible. The overall mortality was 20 per cent and the mean hospital stay 6·1 days. Thirty‐five per cent of the patients presented with neurological complications, and 55 per cent left the hospital well. No advantage of Henry's classical approach over limited exposure and control with metal clips was shown, when mortality, hospital stay and long‐term problems were compared. Because of its relative simplicity we suggest that the metal clipping of the vertebral artery, above and below the site of injury, is an effective technique that can be used to stop the bleeding. One case presented as a false aneurysm of the vertebral artery, following a stab wound. This was successfully treated with excision of the aneurysm and vertebrovertebral artery bypass, using a saphenous vein graft. Copyright © 1988 British Journal of Surgery Society Ltd.
