摘要
目的评价支架内再狭窄的再次血管成形术后，长期血管造影的随访效果。方法血管内再狭窄经再次血管成形术治疗并成功进行随访的１２９例病人共有１５６个病灶的血管造影随访资料进行分析。结果支架内再狭窄的病人成功行重复ＰＴＣＡ术者达９４％，成功完成血管造影随访的达９５％。重复血管成形术后的病人再狭窄率为２７％，病灶再狭窄率２９％。其中局限性病灶的再狭窄率为２０％，弥漫性病灶的再狭窄率达４４％（Ｐ＜０．０１）。结论支架内再狭窄的重复血管成形术成功率高，其长期再狭窄率不高，是一有效的治疗支架内再狭窄的方法。
Objective This study evaluated the Follow up angiographic outcome of successful repeat percutaneous interventional treatment after in stent restenosis and the successful rate and restenosis rate of repeat percutaneous intervention in stent restenosis Methods The subjects underwent repeat percutaneous intervention for the treatment of in stent restenosis and were entered in angiographic follow up program At the end, one hundred twenty nine patients (156 vessels disease) finished the 6 7±5 8 months angiographic follow up Results The primary successful rate for repeat bolloon angioplasty was 94%, the angiographic fellow up was performed in 95% of eligible patients (129 patients , 156 vessels) Restenosis was determined by quantitative angiography The rate of Restenosis defined as >50% diameter stenosis at follow up was 27% (based on patients) and 29% (based on lesions ) The rate of restenosis was 20% at focal lesions and 44% at diffuse in stent restenosis ( P <0 001) Conclusion The successful rate of repeat percutaneous interventional treatment for in stent restenosis was as high as 94%, the overall restenosis rate after repeat bolloon angioplasty for in stent restenosis is low The subgroup of patients with diffuse in stent restenosis is at higher risk of recurrent restenosis
