A 42-year-old woman presented with anterior ST elevation myocardial infarction. Urgent coronary angiography revealed tapering then occlusion of the distal left anterior descending (LAD) coronary artery with no flow in the distal LAD (figure 1A). Balloon angioplasty with a 2.0×8 mm balloon re-established flow into the distal LAD. An angiogram of the right external iliac artery was also performed (figure 1B).heartjnl;104/19/1607/F1F1F1Figure 1Invasive angiography of the left coronary system (A) and the right external iliac artery (B). The coronary angiogram (A) shows tapering and then occlusion (arrow) of the distal left anterior descending coronary artery.
Which of the following explains the abnormal appearance of the external iliac artery (figure 1B)?Atherosclerosis.Concertina effect.Fibromuscular dysplasia.Perforation.Multiple aneurysms.
一名42岁女性因前壁ST段抬高型心肌梗死就诊。紧急冠状动脉造影显示左前降支（LAD）冠状动脉远端逐渐变细然后闭塞，LAD远端无血流（图1A）。使用2.0×8毫米球囊进行球囊血管成形术使血流重新进入LAD远端。还对右髂外动脉进行了血管造影（图1B）。heartjnl;104/19/1607/F1F1F1图1左冠状动脉系统（A）和右髂外动脉（B）的有创血管造影。冠状动脉造影（A）显示左前降支冠状动脉远端逐渐变细然后闭塞（箭头）。
以下哪项解释了髂外动脉的异常表现（图1B）？动脉粥样硬化。手风琴效应。纤维肌发育不良。穿孔。多发动脉瘤。
