Background. There has been many techniques described to preserve the integrity of the aortic root with good outcomes for those with acute type A aortic dissection. However, whether to use these technique in emergency patients presenting with AADA remains controversial.
Methods. Between December 2019 and Feburary 2021, 11 patients underwent aortic root partial repair using a button technique.
Results. The postoperative echocardiography 1 month after operation showed mild regurgitation in 7 cases and moderate regurgitation in 2 cases. Two patients died because of low cardiac outflow. Temporary neurological dysfunction was observed in one patient and hoarseness occurred in one patient.
Conclusions. Our partial aortic root remodeling operation is very easy to operate and has a good short-term effect. It might be a useful strategy for acute type A aortic dissection in patients with one or two Valsalva sinuses affected.
