Neurological deficit and injuries involving the neck arteries

The management of 85 patients with penetrating injuries involving the external (n = 19), internal (n = 6) and common carotid (n = 46), vertebral (n = 10) and brachiocephalic (n = 4) arteries over a 5-year period in one hospital is reviewed. Sixty-three patients had no peroperative neurological deficit; 22 presented with localizing neurological signs. Where there was no deficit, the external carotid (n = 19) and vertebral (n = 10) arteries were ligated without adverse sequelae. Arterial reconstruction was performed of the internal carotid (n = 2) which resulted in a temporary neurological deficit in 7 patients and death in 3. Among the 22 patients with a preoperative neurological deficit, arterial reconstruction was performed in 18, which involved the common carotid in 17 patients and the internal, carotid in 1 patient. There was complete neurological recovery in 11 patients and 2 patients died. Four comatose patients had cerebral revascularization performed without fatality and with complete recovery in 3 of them. CT head scanning was not routinely employed for logistic reasons but has proved of limited value. No intraluminal arterial shunts were used in this series. It would seem that arterial reconstruction is not harmful and may well be beneficial to the young patient with extracranial cerebral arterial injury associated with a neurological deficit. Shunts are probably unnecessary for routine use.
