经桡动脉行无保护左主干病变介入治疗

Percutaneous coronary intervention via radial artery for unprotected left main coronary artery diseases

摘要

摘要: 目的: 回顾性总结29例冠状动脉造影发现为无保护左主干开口及体部狭窄病例的冠脉介入治疗(PCI)资料，以探讨手术的安全性和可行性。方法: 术前给予常规药物治疗，经桡动脉途径行PCI，观察桡动脉穿刺成功率、PCI即刻成功率、手术时间、支架扩张时间和扩张压力、住院期间严重并发症发生率、出院前心绞痛发作情况评估及术前心电图（ECG）特点分析。结果: 29例患者桡动脉穿刺成功率和PCI即刻成功率均为100％，手术时间25～50（38±8）min，支架扩张时间3～7（5±1.3）s，支架扩张压力14～20（16.0±1.9）atm (1 atm=101.325 kPa)，住院期间无严重并发症发生，前臂肿胀3例，术后心绞痛显著缓解。术前胸痛发作时ECG特点：典型“左主干”心电图17例，胸前导联ST-T改变者10例，间歇性左束支阻滞2例。结论: 经桡动脉途径对无保护左主干开口和体部病变行PCI治疗，成功率高，安全有效。

Abstract: AIM: To assess the safety and feasibility of percutaneous coronary intervention (PCI) via radial approach for unprotected left main coronary artery stenosis. METHODS: Twenty nine patients with unprotected left main coronary artery stenosis were treated with PCI via radial approach and the parameters examined were successful recanalization of PCI, surgical time, dilating time and pressure of stent, along with in-hospital complications. RESULTS: The success rate of radial artery puncture and PCI was 100%. Surgical time was 25-50 min (average 30 min). Dilating time was 3-7 sec (average 5 sec) and dilating pressure was 14-20 atmospheres (average 16). There were no severe in-hospital complications. CONCLUSION: PCI via radial artery is safe and effective for patients with left main lesions. There is a high success rate.
