Obstetric Management of Loeys-Dietz Syndrome.

Abstract

Loeys-Dietz syndrome is associated with arterial tortuosity and aortic dissection. Pregnancy may be a period of increased risk for aortic dissection. A 16-year-old primigravid girl was referred to our center with a family history of aortic dissection. Loeys-Dietz syndrome was suspected, and genetic testing confirmed the TGFβ2 (c.988C>T) mutation. A cesarean delivery was performed at 36 weeks of gestation, with no cardiovascular complications. In this case, the uterine vessels were significantly tortuous; this may be an additional finding in Loeys-Dietz syndrome. Women with Loeys-Dietz syndrome warrant special consideration in obstetric management secondary to the risk for aortic dissection. It is recommended that a multidisciplinary team with knowledge about connective tissue disorders and expertise in aortic surgery coordinate maternal obstetric and cardiovascular care.
