为评价V-Flex冠状动脉支架置入后的安全性和再狭窄的发生率，在124例冠心病病人中，138处血管病变植入174个V-Flex冠状动脉支架，成功率为100%。住院期间，1例病人因严重心衰死亡，4例病人出现非Q波心肌梗死，股动脉穿刺处血肿5例，其余病人均无支架相关并发症。122例病人6月临床随访中，16例（13%）出现胸痛或运动试验阳性；108例6个月后定量血管造影显示再狭窄率为24.0%。此结果提示，V-Flex冠状动脉支架对治疗冠状动脉狭窄病变具有较好的安全有效性，且再狭窄发生率低。“,”Aim To investigate the preventive effect of V-Flex stentimplanted into coronary vessels on coronary arteriosclerosis disease. Methods One hundred and seventy-four V-Flex stents implantations were attempted in 124 patients (age 62.5±6.2) with 138 arteriosclerosis wounded vessels. Lesion types were A in 8 vessels， B in 86 vessels and C in 44 vessels. Acute angiographic success was 100%. Results Smooth angiographic results were obtained in all cages. Complications were one non-stent-related death， four non-Q-wave myocardial infarction. Six-month control angiography was performed in 108 (27%) cases of eligible patients and revealed a restenosis rate of 24%. Conclusion Our study show that V-Flex is an excellent coronary stent for treatment of complex lesions， providing excellent results with a low complication rate.
