桡动脉径路行冠状动脉分叉病变球囊保护边支技术可行性的临床研究

Clinical research of feasibility of percutaneous coronary intervention through radial artery in treating coronary artery bifurcation lesions with side branch protected by coronary balloon

目的 探讨冠状动脉分叉病变介入治疗（PCI）球囊保护冠脉边支技术采用桡动脉径路的可行性和安全性.方法 采用桡动脉径路对2013年9月至2014年9月43例冠心痛患者43处真性分叉病变（边支开口为局限病变,内径2.0～2.5 mm）行主支支架外侧球囊保护冠脉边支操作技术.结果 所有患者均经桡动脉径路行冠脉分叉病变介入治疗成功,无中转股动脉径路,技术成功率100％.穿刺处恢复良好,无血肿、假性动脉瘤等发生.结论 桡动脉径路行冠脉分叉病变球囊保护冠脉边支技术可行、创伤小、恢复快、并发症少,安全有效.

Objective To evaluate the safety and feasibility of percutaneous coronary intervention（PCI） through radial artery in treating coronary artery bifurcation lesions with side branch protected by coronary balloon.Methods Forty-three patients with true bifurcation lesions （the side branch ostiumlesions were localized and the side branch diameter was 2-2.5 mm） underwent interventional treatment by bifurcation access with the balloon dilation outside the main branch stent to reserve the side branch.Results All true bifurcation lesions was treated successfully through radial artery without transformation of femoral artery and the puncture site recovered well.No hematomas and pseudoaneurysms occurred.Conclusions PCI through radial artery with the balloon dilation outside the main branch stent to reserve the side branch proved safe and effective in the treatment of bifurcation lesions,and can reduce the complications and had fast recovery.
