A patient is reported who underwent cardiac catheterization 4 years following coronary artery bypass grafting. Cardiac catheterization revealed the presence of a fistulous tract in the wall of the ascending aorta, originating at the site of aortic anastomosis of a saphenous vein bypass graft and ending in the superior aspect of the right sinus of Valsalva. This complication was felt to have resulted from a inadvertent localized dissection of the aorta during bypass surgery. The fistula was also imaged by ultrafast cine computerized tomography which proved a useful non-invasive method for follow-up examination.
报告了一名在冠状动脉搭桥术后4年接受心脏导管插入术的患者。心脏导管插入术显示升主动脉壁存在一个瘘管，起自隐静脉搭桥移植物的主动脉吻合部位，止于主动脉瓣窦右窦的上侧。这种并发症被认为是搭桥手术期间主动脉意外局部剥离所致。瘘管也通过超快速电影计算机断层扫描成像，这证明是一种有用的非侵入性随访检查方法。
