Background and objective:        Ascending aortic aneurysm, aortic dissection and aortic valve regurgitation are emergency conditions that required Modified Bentall Operation. In the past, this technique has a high mortality rate and a lot of complications but now we improve the surgical technique that can decrease mortality and complications. This study was designed to determine surgical outcomes and complications in order to reduce operative mortality, consequences and to improve quality of life.

Methods:      This was a retrospective study chart review in patients which have been performed Modified Bentall Operation at Queen Sirikit heart center between 1 January 2011 – 31 December 2016 to study about the surgical outcome and its complications.    

Results: A total of 72 patients underwent the Modified Bentall Operation. There were 6 patients died postoperatively (8%) and postoperative complications are AF 23 patients (31%), Pneumonia 8 patients (11%), Acute kidney injury 14 patients (19%), Postoperative bleeding 6 patients (8%), Upper GI bleeding 5 patients (6%), Complete heart block 2 patients (2%), Stoke 2 patients (2%) Low cardiac output need to do ECMO support 1 patient (1%), Length of ICU stay is 5 ± 4 day, Length of hospital stay 20 ± 12 day

Conclusions:         Modified Bentall Operation patients with ascending aortic aneurysm or aortic dissection with aortic regurgitation has a good surgical outcome, although this study has higher mortality rate than others we study for improve the surgical outcome for the patients.
