[Successful surgical treatment for acute type a aortic dissection in a patient with late pregnancy]

We report a case of successful surgical treatment for acute type A aortic dissection in a patient in late pregnancy. The patient was a 42-year-old woman who was pregnant for the 1st time. She was taken to hospital with a sudden onset of chest pain at 30 weeks' gestation. She was diagnosed with acute type A aortic dissection with annuloaortic ectasia (AAE) and aortic regurgitation, and was transferred to our hospital for further treatment. Emergency cesarean section and hysterectomy were performed, followed by modified Bentall operation on the next day. The postoperative course was uneventful for both the mother and the infant. Considering the severity of acute type A aortic dissection with AAE, aortic repair might have been performed as soon as possible after cesarean section.
