Risk factors analysis for restenosis after vertebral artery origin stenting
摘要
Abstract
Objective To investigate the in-stent restenosis after vertebral artery ostium stenting (VAOS),and to determine the risk factors for in-stent restenosis. Methods Respective analysis of clinical data of 775 cases received VAOS in Xuan Wu Hospital of Capital Medical University from Jan. 2006 to Dec. 2012. Severe stenosis of vertebral artery ostium were diagnosed by DSA,and followed-up by ultrasound. The risk factors were assessed by COX analysis for in-stent restenosis ≥50%. Results This study included 775 patients. Surgical success rate was 99. 87%(n=774),technique success rate was 99. 48%(n=771 ). Two patients had cerebral hemorrhage after operation,one of them was dead. Four patients had cerebral infarction. The mean follow-up period was 12 months. The restenosis rate was 35. 89%(234/652 ). 79. 91% of restenosis occurred within 12 months after operation. COX analysis showed the vessels diameter after stenting was the independent predictors of in-stent restenosis (P<0. 01). The in-stent restenosis rate of drug-eluting stents was lower than metal-bare stents (HR 0. 532,95%CI 0. 397-0. 713,P<0. 01). Conclusion The in-stent restenosis was peculiarly prone to the smaller vessels diameter after VAOS. Drug-eluting stents were superior to metal-bare stents in preventing in-stent restenosis.关键词
