Minirail双钢丝球囊在冠状动脉介入治疗中的应用

The use of Minirail balloon catheter in coronary intervention

目的 评价一种新型球囊导管———Minirail双钢丝球囊在冠状动脉介入治疗中的有效性和安全性。方法 2 2例冠心病患者 ,其中男 16例 ,女 6例 ,平均年龄 (5 8 8± 8 7)岁 ,行择期冠状动脉介入治疗 ,靶病变 2 4处 (病变位于前降支 17处、回旋支 2处、右冠状动脉 5处 ) ,其中C型病变 5处、B2 型病变 14处、B1 型病变 5处 ,术前平均狭窄程度 91 18%± 5 95 % ,采用Minirail球囊导管行冠状动脉球囊成形术。结果 Minirail球囊扩张操作成功率 10 0 %。球囊扩张后残余狭窄 33 18%± 2 5 14% ;发生明显内膜撕裂 3例 ,慢血流 1例 ;其中 19例患者植入支架共 2 4个 ,术终残余狭窄 1 82 %±5 0 1%。无死亡、Q波性心肌梗死或需紧急冠状动脉旁路移植手术者。结论 Minirail球囊导管方便、实用、安全、有效 ,在冠状动脉介入治疗中具有一定临床应用价值。

Objective To evaluate the effectiveness and safety of a new designed balloon catheter, the Minirail balloon catheter in coronary intervention Methods Twenty two consecutive patients with coronary artery disease (male 16, female 6, mean age 58 77±8 69 years) were enrolled the study Selective angioplasty was performed for 24 target lesions (17 in LAD, 2 in LCX, and 5 in RCA) Among these target lesions were 5 type C, 14 type B 2, and 5 type B 1 lesions The average extent of narrowing before procedure was 91 18%±5 95% Target lesions were dilated with Minirail balloon catheters Results All of the target lesions were successfully dilated with Minirail balloon catheters The average residual stenosis was 33 18%±25 14% after balloon angioplasty Significant dissection was seen in 3 of the cases, and slow reflow in another one Twenty four stents were implanted in 19 cases The final residual stenosis was 1 82%±5 01% at the end of procedure No death or Q wave myocardial infarction happened No emergency bypass surgery needed Conclusion Minirail balloon catheter is safe, effective, and easy to be used in coronary intervention
