Abstract:Objective To summarize the experiences in surgical treatment of ascending aortic root aneurysms. Methods One hundred and one patients （age ranging from 14 to 72 years, mean 42.7 years） with ascending aortic root aneurysms were diagnosed as having Marfan syndrome （58 cases）, annuloaortic ectasia （34 cases）, bicuspid aortic valve （5 cases）, aorto arteritis （4 cases） combined with aortic valve incompetence （96 cases） and aortic valve stenosis （4 cases） , preoperatively with type A dissection （26 cases） and acute left heart failure （5 cases）. Our operations consisted of 4 Wheat procedures, 13 Cabrol or modified Cabrol procedures, 1 David and 83 Bentall procedures. Concomitant operations included hemi-arch replacement or descending aorta intraluminal stent grafting （16 cases）, total arch replacement or descending aorta intraluminal stent grafting （4 cases）, mitral valve replacement or anuloplasty （14 cases） and coronary artery bypass grafting （CABG, 8 cases）. Results The overall mortality was 6.9%（7/101）, and decreased to 3. 6%（3/83） after the year 2000. Main postoperative complications were low cardiac output （10 cases）, respiratory insufficiency （9 cases）, and renal inadequacy （9 cases）. Follow-up was completed in 94 patients. During the period of follow-up, one patient died and 5 patients with Marfan syndrome suffered with type B dissection. Conclusion Bentall procedure is the method of choice for ascending aortic root aneurysms. Preoperative left heart function and surgical techniques give the crucial impact on the outcome of surgery.
