经皮冠状动脉成形术与支架置入术的临床应用

目的 分析经皮冠状动脉成形术(PTCA)及支架植入术(支架术)治疗冠心病的临床疗效。方法 212例冠心病患者中，稳定型心绞痛46例，不稳定型心绞痛78例，心肌梗死104例。单支血管病变84例，双支血管病变62例，三支血管病变66例。共处理病变血管298处，置入支架252枚。其中左前降支(LAD)118处，右冠脉(RCA)84处，左回旋支(LCX)84处，左主干(LM)2处。观察PTCA和／或支架术的成功率、并发症和术后6个月靶病变再血管化率。结果 PTCA和／或支架术的技术成功率为97．6％，临床成功率为97．2％；并发症发生率为11．3％，多为穿刺局部并发症。6个月靶病变再血管化率为2．83％。结论 PTCA和支架术是一种安全、有效的介入性治疗技术，成功率高、严重并发症少。

Clinical Application of Percutaneous Transluminal Coronary Angioplasty and Intracoronary Stent Implantation

Objective To evaluate clinical outcomes of percutaneous transluminal coronary angioplasty (PTCA) and stenting in the patients with coronary artery disease in our hospital. Methods Two hundred and twelve patients underwent PTCA and stenting, the patients suffered from stable angina, unstable angina and myocardial infarction were 46, 78 and 104, respectively. 84 patients had single vessel disease, 62 patients double vessel disease and 66 patients triple vessel disease. 298 lesions were treated with 252 stents implanted. 118 stents were implanted into LAD, 84 stents into RCA, 84 stents into LCX and 2 stent into LM. Results The technical success rate for PTCA and stenting was 97 6%, clinical success rate was 97 2%, complication was 11 3%. Most of complication was in peripheral puncturing sites. Restenosis rate in target vesseles 6 months after PTCA and/or stenting was 2.83%. Conclusion PTCA and stenting is an effective and safe therapy with a high immediate technical success rate and few major in|hospital events.
