Objective: An inverse relationship between volume and mortality in some cardiothoracic surgical procedures has been previously established, leading to suggestions that acute aortic dissection should not be operated in community or low volume heart centers. We therefore reviewed our experience to compare with published data. Methods: Retrospective review of 27 patients who underwent proximal aortic surgery by a single surgeon at an inner city community hospital between May 2004 and April 2015. 16 patients, mean age 51.7 ± 13.6 years old, 75.0% males underwent emergency surgery for acute Stanford type A aortic dissection, while 9 with root or ascending aortic aneurysm, mean age 50.3 ± 15.0 years old, 88.9% males had elective proximal aortic surgery. 2 patients with arch aneurysm were excluded. Results: Four (25.0%) patients with acute dissection were in Penn class A, 3 (18.7%) Penn B, 3 (18.7%) Penn C and 6 (37.5%) Penn B+C. 10 (62.5%) patients underwent emergency root replacement with 60.0% (6/10) mortality all related to malperfusion including 2 patients with bloody stools, while 6 (37.5%) underwent supracoronary graft replacement with 16.6% (1/6) mortality from cardiac tamponade. The 5-year survival was 89.0%. In patients with aortic aneurysm, 8 (88.9%) underwent elective root replacement and 1 (11.1%) supracoronary graft replacement with zero mortality. Conclusion: Supracoronary graft replacement is performed for the majority of uncomplicated acute type A dissections and can be undertaken by the average general cardiac surgeon with acceptable results. Visceral malperfusion especially when associated with bloody stools portends a poor prognosis, and aortic dissection should be excluded in any Marfan patient presenting with acute abdomen. Delaying intervention in attempting transfer to a tertiary hospital can potentially increase preoperative mortality, known to rise with each passing hour from onset of acute dissection. Patients presenting therefore to community hospitals should probably undergo surgery there to avoid complications associated with delay. 展开更多
