Trends in the management of traumatic vertebral artery injuries.
From 1975 to 1988, 25 patients with a vertebral artery (VA) injury were treated. Admission neurologic status was intact in 14 patients (56 percent). Eight patients had deficits due to direct nerve or spinal cord injury, two patients had symptoms referable to vertebrobasilar ischemia, and one patient had a contralateral deficit due to an associated carotid artery injury. Twenty-two of 25 patients (88 percent) underwent diagnostic arteriography. Twelve patients (48 percent) with 9 occlusive and 3 minimal injuries were observed. Seven patients (28 percent), three with exsanguinating hemorrhage, were treated by operative exploration and VA ligation. Six patients (24 percent), two with a VA pseudoaneurysm and four with an arteriovenous fistula, were managed by percutaneous transcatheter embolization. The neurologic status was unchanged or improved in 22 patients (88 percent) at discharge. Two patients developed Horner's syndrome after VA ligation. Transient posterior circulation ischemia occurred in a single patient after percutaneous transcatheter embolization. There was no mortality. The majority of VA injuries are best managed by nonoperative methods. Untoward neurologic sequelae are rare. Operative intervention and VA ligation should be reserved for patients with active hemorrhage or large pseudoaneurysms and arteriovenous fistulas which cannot be embolized.
