目的：观察钢丝球囊锚定技术在严重弯曲伴钙化的冠状动脉病变介入治疗中的应用效果。方法选择56例经冠脉造影明确为严重弯曲伴钙化病变，在强支撑指引导管、病变部位充分球囊预扩张和双钢丝等技术基础上运用分支锚定技术行支架植入失败的患者，采用钢丝球囊锚定技术，评价其临床效果并观察并发症发生情况。结果47例采用钢丝球囊锚定技术成功植入支架，手术成功率达83.93%，其中2例术中发生慢血流现象，予以冠脉内注射盐酸替罗非班和地尔硫后恢复血流；另外9例因钙化严重，经血管内超声确认系360度内膜下严重钙化，改行冠脉内旋磨术后成功植入支架。结论钢丝球囊锚定技术处理严重弯曲钙化冠状动脉病变安全、有效。

Objective To observe the effect of application wire-balloon-anchoring technique in severe bending with calci-fied coronary artery disease.Methods To observe the complications and evaluate the clinical effects of wire-balloon-anchoring technique,5 6 patients with severe bending with calcified lesions diagnosed by coronary angiography were adopted the technique after failing to application of strong support of guiding catheter,full balloon pre-expansion and double-wire-branch-anchoring technique.Results Forty-seven patients with wire-balloon-anchoring technique successful stenting,success rate was 83.93%. Two patients with slow blood flow phenomenon restored blood flow after intravascular inj ection with tirofiban and diltiazem. Another nine patients with extreme calcification of 360 degree of intima diagnosed by intravascular Ultrasound (IVUS)were successfully stented after switching to apply rotational atherectomy.Conclusion Wire-balloon-anchoring technique is a safe and effective means of dealing with severe bending and calcified coronary artery lesions.
