摘要
目的 :评估低压力球囊预扩张、高压力冠状动脉 (冠脉 )内支架置入的可行性和效果。方法 :10 6例选择性支架置入的冠心病患者 ,低压力 (40 5 .3～ 6 0 7.9kPa)球囊预扩张后 ,冠脉内置入支架 ,高压力 12 15 .9～ 16 2 1.2kPa)释放。结果 :共 12 7处病变置入支架 135只 ,球囊预扩张平均压力为 4 86 .4kPa ,平均支架释放压力为 136 7.9kPa ,即刻支架置入和释放的成功率为 10 0 %。低压力预扩张冠脉内膜撕裂发生率为 3.9%(5 / 12 7处 )。结论 :选择性冠脉内支架置入 ,低压力球囊预扩张、高压力支架置入是一种安全、有效和可行的方法 ,可能减少冠脉内膜撕裂的发生率。
Objective:To evaluate the feasibility and efficacy of the low pressure balloon predilation and high pressure coronary stenting in patients with coronary artery disease.Method:After low pressure ( 405.3～ 607.9 kPa) balloon predilation, high pressure ( 1 215.9～ 1 621.2 kPa) was used in the coronary stent deployment in 106 cases.Result:One hundred and thirty five stents were implanted in 127 lesions. The average stent deployment pressure was 1 367.9 kPa and the procedure success rate was 100%. The coronary dissection rate was 3.9% and the restenosis rate was 9.3% in the follow six months after the operation.Conclusion:In selected patients received stent implantation, low pressure balloon predilation and high pressure coronary stenting is a safe, feasible and efficacious stent deployment method, which is able to decrease the rate of dissection and restenosis.
