To evaluate the use of temporary intraluminal shunt (IS) during operations in our patients for asymptomatic carotid stenosis (ACS) of the internal carotid artery (ICA).Complications of ICA endarterectomy were reviewed in two groups of asymptomatic patients. In group A (144 patients, operation 1972-1985) temporary IS was used in 43 patients with the intraoperatively measured ICA back pressure50 mmHg. In group B (170 patients, operation 1986-1998) shunt was used in all cases.The incidence of neurologic deficit was higher ia group A than in group B (5.6% vs 1.2%, p0.05). Within group A, the incidence of neurologic deficit was significantly higher in the subgroup with back pressure50 mmHg, and thus without shunt, than in group B with routine use of shunt (6.0% vs 1.2%, p0.05). There were no differences in the incidence of shunt-related complications between the groups (3.0% vs 4.0%, p0.05). We had no mortality after operations of asymptomatic patients.The routine use of IS reduced the rate of intraoperative and early postoperative neurologic complications of asymptomatic carotid endarterectomy, and it was not associated with a higher incidence of complications. |
