摘要:
目的 用99Tcm-甲氧基异丁基异腈(99Tcm-MIBI)运动-静息心肌灌注显像评价经皮腔内冠状动脉成形术(PTCA)的疗效。方法 20例冠心病患者在PTCA术前和术后应用99Tcm-MIBI行运动负荷.静息心肌灌注显像,并对图像进行半定量分析。其中8例患者于术后6个月再次心肌灌注显像。结果 对20例患者的27支冠状动脉呈狭窄病变进行PTCA,术前血管的平均狭窄为(84.3±9.2)%,术后平均残留狭窄减为(31.2±9.1)%。运动负荷-静息显像显示可逆性缺损(心肌缺血)的心肌节段数由术前的55个(30.6%)减为术后的10个(5.6%),差异有显著性(χ2=38.02,P<0.005)。术后心肌灌注的改善率为81.8%,8例患者术后6个月心肌显像显示3例出现缺血节段,冠状血管造影证实为再狭窄。结论 99Tcm-MIBI运动负荷-静息心肌灌注显像是一种有效的无创性的判断PTCA术后疗效及再狭窄的方法。
Abstract:
Objective To evaluate the outcomes of stress-rest 99Tcm-MIBI perfusion imaging in patients with percutaneous transluminal coronary angioplasty (PTCA). Methods Twenty patients with coronary heart disease underwent repeated 99Tcm-MIBI stress-rest perfusion imaging before and after PTCA, and semi-quantitative analysis, 8 cases of them repeated coronary angiography after 6 monthes. Results Twenty patients with total of 27 coronary artery stenosis were distended, the average vascular stenosis were (84.3 ±9.2)% before PTCA, and were reduced to (31.2±9.1)% after PTCA. Stress-rest perfusion imaging showed myocardial segments were reversible defect (myocardial ischemia) from 55 (30.6%) befor PTCA to 10 (5.6%) after PTCA, there were significant difference (χ2=38.02, P<0.005). The improved rate was 81.8%, 8 patients underwent repeated stress-rest SPECT imaging after 6 monthes, 3 cases appears ischemia segment, and coronary angiography confirmed was restenosis. Conclusion 99Tcm-MIBI stress-rest perfusion imaging is a useful noninvasive method for evaluating the effect of PTCA and for restenosis.
