经桡动脉途径无保护冠状动脉左主干分叉病变介入治疗

 目的 探讨经桡动脉途径PCI在无保护左主干分叉病变中治疗的可行性和疗效.方法 回顾性分析我院无保护左主干分叉病变择期行PCI的患者22例,21例置入药物洗脱支架,单支架置入7例,双支架置入14例,14例置入双支架的患者均成功进行对吻球囊扩张,1例系支架术后再狭窄,单纯行切割球囊成形术.术后每15 d或1个月门诊复查1次,3～9个月行冠状动脉造影复查.结果 22例PCI均取得成功,术后达TIMI 3级血流,住院期间主要不良心脏事件1例(4.55%),冠状动脉造影复查显示支架内再狭窄2例(10.53%),1例再次行PCI术.术后平均随访(16.86±6.90)个月,随访期内死亡1例.结论 经桡动脉径路无保护左主干分叉病变PCI即刻成功率高,有较好的近、中期疗效.

Transradial percutaneous coronary intervention for patients with unprotected left main coronary artery bifurcation lesions

Objective To study the clinical effectiveness and feasibility of transradial percutaneous coronary interventional （rPCI） for patients with unprotected left main coronary artery bifurcation lesions. Methods Between June 2005 and October 2007, a total of 22 consecutive patients with unprotected left main coronary artery bifurcation lesions were treated by rPCI. Drug-eluted stents were employed in 21 patients, including single stent in 7 and double stents in 14. Single FlEA with cutting balloon in 1 patient with restenosis after stenting. Final kissing balloon post-dilatation was employed with a 100% success rate in 14 patients receiving double stents. Patients enrolled in the study under-went clinical evaluation every two weeks or one month after the procedure. Routine coronary angiography was performed 3 to 9 months after the procedure. Results Procedure success was achieved in 22 patients. The stenosis affected arteries had TIMI 3 flow at the end of the procedures. and angingraphic follow-up was conducted in 86.36% of patients （19/22） .In-hospital major adverse cardiac event （MACE） occurred in 1 patient. Restenosis was found in 2 patients, of whom 1 patient received PCI again. Mean clinical follow-up period was 16.86±6.90 months. There was one death during the follow-up period. Conclusions Transradial pereutaneous coronary intervention for the treatment of unprotected left main coronary artery bifurcation lesions is feasible and highly successful, bringing about near to or mediumterm good outcomes.
