The authors report the results of 8 cases of percutaneous transluminal coronary angioplasty of occluded arteries: the artery concerned was the proximal segment of the left anterior descending artery in 5 cases and the proximal segment of the right coronary artery in 3 cases. All patients had unstable angina with a very positive exercise stress test. The conservation of viable myocardium was the result of an excellent collateral circulation from the controlateral vessel in all patients. In 7 out of the 8 cases, the guide wire and dilating balloon were correctly positioned by opacifying the distal segments of the occluded artery by injection of contrast into the controlateral artery. Almost simultaneous injection of the occluded and controlateral vessels allowed evaluation of the length of the occlusion. Controlateral opacification disappeared immediately after adequate recanalisation to reappear during inflation of the balloon. These cases show that in patients with chronic coronary occlusion, opacification of its distal segments by injection of contrast into the controlateral vessel seems to be helpful and without risk to the patient.
作者报告了8例经皮腔内冠状动脉成形术治疗闭塞动脉的结果：其中5例病变动脉为左前降支近端，3例为右冠状动脉近端。所有患者均患有不稳定型心绞痛，运动负荷试验呈强阳性。所有患者存活心肌得以保留是对侧血管良好侧支循环的结果。8例患者中有7例，通过向对侧动脉注射造影剂使闭塞动脉远端显影，从而正确定位导丝和扩张球囊。几乎同时对闭塞血管和对侧血管进行注射可评估闭塞长度。充分再通后，对侧显影立即消失，球囊扩张时又重新出现。这些病例表明，对于慢性冠状动脉闭塞患者，向对侧血管注射造影剂使闭塞动脉远端显影似乎是有益的，且对患者无风险。
