切割球囊临床应用的有效性和安全性评价

Evaluation on the safety and efficacy of cutting balloon angioplasty

目的 探讨切割球囊临床应用的安全性和有效性。方法 对 1 3 1例患者 1 4 2处狭窄病变进行切割球囊或切割球囊 +支架治疗。结果 1 4 2处狭窄病变行切割球囊治疗中 4次失败 ,成功率为 97 2 %。切割球囊治疗支架内再狭窄、开口部病变、分叉病变和小血管弥漫性病变以及其他类型病变各为 6 9处、1 6处、1 9处、7处和 2 7处 ,7例切割球囊扩张后发生内膜撕裂 ,均为A型夹层 ,发生率为 5 3 %,术中无死亡和急性心肌梗死及其他严重血管并发症发生。失败原因与病变严重钙化以及切割球囊不能达到或通过狭窄部位有关。

Objective To evaluate the safety and efficacy of cutting balloon angioplasty(CBA) Methods 131 patients with 142 lesions underwent successful coronary angioplasty with CBA or with CBA+stent Results The procedural success rate was 97 2% The lesion types treated by CBA included 69 lesions with in stent restenosis, 16 with ostial lesion (LAD and LCX), 19 with bifurcation lesion, 7 with small vessel diffuse disease and 27 with proximal lesion The dissection A type rate for CBA was 5 3% There were no death, acute myocardial infarction and severe dissections complications after CBA CBA failed in four cases, the reason for that was related to tortuous vessel and severe calcium lesion Conclusion As a new device, cutting balloon is safe and effective in coronary angioplasty
