A 53-year-old woman was referred to us for reoperation of aortic root. Twenty-three years ago, she was diagnosed with aortitis and suffered from annuloaortic ectasia, aortic regurgitation, severe stenosis of left carotid and subclavian arteries and occulusion of the main trunk of left coronary artery. The left coronary system was perfused by collateral arteries from right coronary artery. She had undergone original Bentall procedure( Cooley graft 26 mm+SJM valve 25 mm) with coronary artery bypass grafting (CABG)[saphenous vein graft (SVG)-left anterior descending artery (LAD)]. When she was 52 years old, she suffered from angina on efforts. Computed tomography and catheter angiocardiogram revealed pseudoaneurysm formation due to detachment of right coronary artery button and occulusion of SVG. We underwent redo aortic root replacement (Hemashield graft 26 mm+On-X valve 23 mm) with redo CABG (SVG-LAD). Eight mm graft was interposed between composite valve graft and right coronary button. Postoperative course was uneventful. She was discharged from the hospital on the 17th day, and is now doing well without any symptoms.
一名53岁女性因主动脉根部再次手术被转诊至我院。23年前,她被诊断为主动脉炎,并患有主动脉瓣环扩张、主动脉瓣反流、左颈动脉和锁骨下动脉严重狭窄以及左冠状动脉主干闭塞。左冠状动脉系统由右冠状动脉的侧支动脉供血。她曾接受过初次Bentall手术(26mm的Cooley移植物+25mm的SJM瓣膜)及冠状动脉旁路移植术(CABG)[大隐静脉移植物(SVG)-左前降支动脉(LAD)]。52岁时,她出现劳力性心绞痛。计算机断层扫描和导管心血管造影显示,右冠状动脉纽扣状结构分离及SVG闭塞导致假性动脉瘤形成。我们为她进行了再次主动脉根部置换术(26mm的Hemashield移植物+23mm的On-X瓣膜)及再次CABG(SVG-LAD)。在复合瓣膜移植物与右冠状动脉纽扣状结构之间置入了8mm的移植物。术后过程顺利。她于第17天出院,目前情况良好,无任何症状。
