Objective To find out the follow-up results of early in-stent restenosis (ISRS) and develop effective way to improve clinical treatment and precaution of restenosis. Methods The data from a registry of 51 consecutive patients who underwent elective carotid artery angioplasty and stenting (CAS) at our institution between Jan. 2003 and Sept. 2005 were retrospectively reviewed. Complete data for 37 of these patients were available. All patients underwent duplex ultrasound scanning in follow-up period, which was used to determine the degree of restenosis. Results CAS was performed in 37 patients, 8.1% (3/37) were women. Mean age was (70.5±5.9) years. Mean time of follow-up was (12.2±7.7) months. Sixteen (43.2%) caces of ISRS ( gt;30%) were found by color duplex ultrasound scanning, but only 1 (2.7%) ISRS was found  gt;50%; 3 female patients had minor ISRS. Among all factors, female patients had higher incidence of ISRS than male (P=0.038); balloon-expanding after stenting and accompanying with other artherosclerosis of periphery vessel had correlation about ISRS (P=0.037, P=0.016). Conclusion The severe restenosis rate is acceptable. Female patients were more likely to have ISRS. Balloon-expanding maybe have effect on reducing incidence of ISRS and controlling artherosclerosis was helpful.
