[Bentall Operation for Pregnant Women with Marfan's Syndrome].

A 35-years-old pregnant woman with Marfan's syndrome visited the emergent department. She had sudden severe back pain. She was at the 20th week of gestation. An emergent chest computed tomo-graphy scan showed Stanford type B acute aortic dissection. After admission, strict blood pressure control was started. According to aortic valve insufficiency and fluid retention with pregnancy, acute heart and respiratory failure was getting worse. It seemed risky for both mother and the fetus to continue pregnancy. After sincere and detailed discussion between the patient and our multidisciplinary medical team, the patient decided to continue pregnancy. An urgent Bentall operation was performed. A careful attention was paid for the fetus during and after the surgery. Strict blood pressure control was also continued. The mother and the 30-week-gestation newborn recovered uneventfully. During four years of follow-up, thoracic and thoraco-abdominal aortic replacement was performed. The patient survived all of these procedures without any complication.
