目的 探讨经皮冠状动脉腔内成形术 (PTCA)及冠状动脉内支架植入术 (CASI)对冠状动脉狭窄及完全闭塞的疗效。 方法 对 30例冠状动脉粥样硬化性狭窄或闭塞 ,1例缺血性心肌病冠状动脉狭窄和 1例多发性结节性动脉炎致急性心肌梗塞患者的 5 0支病变血管实施 PTCA或 CASI术。术前、术后和随访期复查冠状动脉造影图像。结果 手术总成功率 96 .9%,1例冠心病急性心肌梗塞患者术后 2周因心原性休克死亡 ,1例冠心病患者 PTCA术后 3月再狭窄而再次手术 ,随访期 30例患者病变血管内径较术前明显增大。结论 PTCA及 CASI术对各种原因引起的冠状动脉狭窄及闭塞有肯定的疗效 ,成功率高 ,并发症少。
Objective To investigate the effect of percutaneous transluminal coronary angioplasty (PTCA) and coronary stenting (CASI) on coronary artery stenosis and complete occlusion. Methods PTCA or CASI was performed in 30 patients with atherosclerotic coronary artery stenosis or occlusion, 1 coronary artery stenosis of ischemic cardiomyopathy and 1 patient with acute myocardial infarction caused by multiple nodular arteritis . Preoperative, postoperative and follow-up review of coronary angiography. Results The operation assembly rate was 96.9%. One patient with acute myocardial infarction died of cardiogenic shock 2 weeks after operation, and one patient with coronary artery disease underwent restenosis after 3 months of PTCA. During the follow-up period, 30 patients’ The diameter was significantly increased compared with preoperative. Conclusions PTCA and CASI have definite curative effect on coronary artery stenosis and occlusion caused by various causes, with high success rate and few complications.
