目的观察边支球囊保护技术在分叉病变PCI术中的有效性及安全性。方法 89例患者冠状动脉真性分叉病变边支直径小于2.5 mm,随机分为观察组(44例)和对照组(45例)。观察组在PCI术中采用边支球囊保护技术,对照组在PCI术中采用钢丝保护技术。观察手术的安全性及有效性。结果两组PCI成功率均为100%,观察组手术时间、造影剂用量、边支受累情况及边支血管支架置入数量、术中并发症明显少于对照组(P<0.05);随访期间心血管不良事件发生率有降低的趋势。结论边支球囊保护技术简单、方便,在临床上有一定的应用价值。
Objective To observe the effectiveness and safety of percutaneous balloon protection in bifurcation PCI. Methods Eighty-nine patients with coronary artery bifurcation lesion with a diameter of less than 2.5 mm were randomly divided into observation group (44 cases) and control group (45 cases). The observation group used the technique of peri-branch balloon protection in PCI and the control group used the wire protection technique in PCI. Observe the safety and effectiveness of surgery. Results The success rates of PCI in both groups were all 100%. The operation time, contrast medium dosage, the involvement of the side branches and the amount of stent implantation in the observation group were significantly lower than those in the control group (P <0.05). During the follow-up period Cardiovascular adverse events have a decreasing trend. Conclusion The technique of balloon protection is simple and convenient and has certain clinical value.
