摘要
目的探索冠状动脉内支架植入术在冠心病治疗中的应用价值。方法对５２例冠心病患者中的２６例行经皮冠状动脉腔内成形术（ＰＴＣＡ），２６例的２９支冠状动脉行ＰＴＣＡ术并植入３３个支架，其中急性心肌梗塞患者占３６．５％，陈旧性心肌梗死者占７．７％，不稳定性心绞痛者占５５．８％；多支病变者占６９．２％，Ｂ２型以上病变占６７．３％。结果３３个支架植入全部成功。术后随访２周～２年，２６例ＰＴＣＡ术后４例心绞痛复发，２例复查冠脉造影证实原靶血管再狭窄。２６例冠状动脉支架植入术后１例心绞痛复发，其中２例无保护左主干冠状动脉支架植入术成功，心绞痛症状缓解。结论冠状动脉支架植入术明显降低了靶血管急性闭塞和再狭窄的发生率；无保护左主干冠状动脉支架植入术是可行的。
Objective To investigate the clinicel application of intracoronary stent implatation in the treatment of coronary atherosclerotic heart disease.Methods Thirty three intracoronary stents were implanted in to 29 coronary arteries under procedures of percataneous transluminal coronary angioplasty in 52 patients 36.5% patients had acute myocardial infarction,55.8% had unstable angina pectoris,and 7.7% had old myocardial infarction.Of the lessions,69.2% were of multiple vessel,67.3% B2 and C type.Results All stents were implanted successfully;All clinical results were recorded during 2 years.Four cases after PTCA and one after PTS had recurrence of chest pain.Two cases of unprotected left main coronary artery disease(LMCA) treated with stents successfully.Conclusion This study demostrated that stenting results in a large,smooth lumen and a lower incidence of restenosis and abrupt closure compared to PTCA.Unprotected left main coronary artery disease also can be treated with stent.
