[Endarterectomy for carotid stenosis].

OBJECTIVE

To discuss the indications, anesthesia and surgical techniques of carotid endarterectomy (CEA).

METHODS

Twenty-two sides of carotid stenosis were revealed in 20 patients. CEA was performed under general anesthesia in 21 sides and local anesthesia in one. The time of carotid occlusion ranged from 27 to 52 minutes (average 35.5 min) in 20 operations, and intraoperative shunt was used in the other two. Fifteen operations were monitored with EEG.

RESULTS

The postoperative course was uneventful in 17 patients after 18 operations, while transient muscle strength decrease on contralateral side and ipsilateral lower facial paresis occurred after three operations in the other three patients. Nineteen patients were followed-up for 38 months on the average. Among nine patients with TIA, ischemic attacks ceased in eight and decreased in one. Improvement was achieved in six patients with cerebral infarction. One patient without symptoms of carotid ischemia was still normal after operation.

CONCLUSION

Carotid endarterectomy is a safe and effective way for treating carotid stenosis.
