摘要
目的 研究对完全闭塞的血管成功ＰＴＣＡ术后，选择性置入支架的近期及远期临床疗效及血管造影结果。方法４９８例完全血管闭塞的病人中，能成功进行ＰＴＣＡ并置入支架，完成临床及血管造影随访的８４例病人，共放置９８个支架，观察其术后近期及远期临床事件发生率及血管造影的特点。结果 置入支架后，住院期间，５％的病人出现亚急性血管闭塞，无死亡，１例发生心肌梗塞，至半年随访终点时，共有３０％的病人出现再狭窄，血管闭塞率１３％，重施血管再通术２０％，半年后的无心脏事件率为６８％。结论对完全血管闭塞病人，选择性支架术明显降低再狭窄及血管闭塞率，减少临床心脏事件的发生率。
Objective This study investigated whether stenting improved the short and long-termclinical and coronary angiographic results of chronic coronary occlusions. Methods 104 patients with asatisfactory results after successful recanalization by PTCA of a chronic coronary occlusion from fourhundred ninety eight consecutive patients undergoing coronary angioplasty for chronic total occlusionwere rolled in the study, 84 of those patients (80 % ) with a total occlusion, underwent repeat angiography within 6 months (2. 5-9 months), 98 stems implantation aimed to cover the site of the occlusionas well as adjacent diameter stenosis>70% and all possibly induced dissections pertinent angiographicand procedural variables obtained at the time of the intervention and the clinical cardiac events were entered into the date base of computer to assess the outcome at follow up. Results During the six monthfollow up, the rate of restenosis and occlusion were 30% and 13% respectively' Conclusion Comparedwith previous reports on stand alone balloon angioplasty, stenting of nonactute total coronary occlusionslowers the 6 months restenosis and reocclusion rate, improve the clinical and angiographic results. It isrecommended regardless of the primary PTCA results.
