Objective To explore clinical features and surgical strategies for patients with aortic dissection (AD) manifesting as pure aortic regurgitation (AR), avoid preoperative misdiagnosis, and provide reference for clinical diagnosis and treatment. Methods Clinical data of 5 AD patients who were preoperatively diagnosed as pure AR in Beijing Fu Wai Hospital from January 2005 to May 2012 were retrospectively analyzed. There were 4 male and 1 female patients with their median age of 41 (34-53) years. All the 5 patients were diagnosed as AD during the operation. One patient received aortic valvuloplasty, 1 patient received Wheat procedure, and 3 patients received Bentall procedure. Clinical manifestations, accessory examinations, intraoperative findings, surgical strategies and follow-up results were summarized. Results No postoperative death or complication occurred in this study. Echocardiogram of patient 1 before discharge showed that transverse diameters of the ascending aorta and aortic sinus decreased with satisfactory closure of aortic valves but no AR. Echocardiogram and CT all showed normal function in mechanical valves and patent blood vessel prosthesis in the other 4 patients. All the 5 patients were followed up for 4 (1-5) years and were alive during follow-up. Echocardiogram showed normal function in mechanical valves and patent blood vessel prosthesis without paravalvular leak in 4 patients and mild AR in 1 patient. Conclusion AD manifesting as pure AR is rare and easily misdiagnosed preoperatively. Careful analysis of medical history and accessory examinations can reduce the risk of misdiagnosis. Appropriate surgical strategies should be chosen according to intraoperative findings of intimal tears and aortic sinus damage of AD.
