Interventional therapy for carotid artery stenosis: Report of 40 cases / 中国微创外科杂志

ABSTRACT

Objective To summarize the experience of 40 patients with carotid artery stenosis treated by carotid artery stenting (CAS). Methods Endovascular plasty and stent placement were performed in 40 patients with carotid artery stenosis from October 2000 to July 2002. A total of 43 stents were placed into, comprising 39 WALLSTENT stents and 4 SMART stents. Out of the 40 cases, cerebral protection devices were used in 5 cases. Results The stent placement was completed successively in all the patients.Diameters of carotid artery all returned to 4mm or above.Mild intraoperative ischemic stroke occurred in 2 cases, and severe intraoperative ischemic stroke was found in other 2 cases visual field loss of the left eye in 1 case, with after-effects even 3 months after surgery; loss of consciousness and right hemiplegia in 1 case, whom was cured to full consciousness subsequently. The complication rate was 10% (4 of 40) and the rate of severe ischemic stroke was 5% (2 of 40). No complications were seen in patients with cerebral protection devices. Conclusions CAS is effective in the treatment of carotid artery stenosis. Carotid stenting with cerebral protection devices may further ensure the patients' safety.
