本文总结31例经皮冠状动脉腔内血管成形术(PTCA)前后作运动核素心肌灌注断层显像,PTCA前冠状动脉平均狭窄82.58±16.04%,术后为17.7±6.21%,26例(83.9%)运动心肌灌注断层显像显示PTCA术后心肌缺血完全消失及明显改善。90.3%病例PTCA术后运动试验较术前进步。认为运动心肌灌注断层显像可做为判断PTCA疗效的有效方法。
This review summarizes the results of myocardial perfusion imaging in 31 patients before and after percutaneous transluminal coronary angioplasty (PTCA). The average coronary stenosis before PTCA was 82.58 ± 16.04%, after operation was 17.7 ± 6.21%, while in 26 patients (83.9% %) Myocardial perfusion imaging showed myocardial ischemia completely disappeared after PTCA and significantly improved. 90.3% cases of PTCA postoperative exercise test compared with the preoperative progress. That exercise myocardial perfusion tomography can be used as an effective method to determine the efficacy of PTCA.
