A patient with Marfan's syndrome who developed an acute aortic dissection at 28 weeks of pregnancy treated with aortic root replacement.

The patient was a 31-year-old pregnant woman who gave birth to her first child by vaginal delivery 7 years ago. She was diagnosed with Marfan's syndrome based on physical findings; however, the condition was not diagnosed before the onset. The patient developed acute aortic dissection at 28 weeks of pregnancy. A cesarean section was first performed to save the patient's life; then, a total hysterectomy was performed to prevent the risk of postpartum hemorrhage. Furthermore, aortic root replacement was performed using a temporary mechanical valve. The patient and her child have survived without any complications.
