我院自1988年9月,完全依靠本院人员成功地进行了2例经皮冠状动脉腔内成形术(PTCA),现报告如下。1 病例报告 例1,男,48岁.劳生心绞痛1月余。术前安静心电图ST段水平下降 0.5mm,B超潘生丁试验阳性;诱发心绞痛伴心尖部运动减弱。冠状动脉造影为单支病变- 右冠状动脉发出后降支前有1段90％狭窄处。PTCA术中经过顺利,扩张后遗留30％狭窄。术后心绞痛消失。5d安静心电图正常,完成次极量运动试验,但ST段仍水平下降1mm;B超潘生丁试验转为
Our hospital since September 1988, totally rely on our hospital staff successfully conducted 2 cases of percutaneous transluminal coronary angioplasty (PTCA), are as follows. 1 case report 1, male, 48 years old. Labor angina more than 1 month. Preoperative quiet ECG ST segment levels decreased by 0.5mm, B super-dipyridamole test positive; induced angina with apical movement decreased. Coronary angiography as a single lesion - right coronary artery after descending branch has a 90% stenosis. PTCA surgery after the smooth, 30% left after the expansion of the narrow. Angina disappeared after surgery. 5d quiet electrocardiogram normal to complete the submaximal exercise test, but the ST segment is still level down 1mm; B super diphtheria test to
