Pregnancy Management and Successful Outcome of Ehlers-Danlos Syndrome Type IV

Ehlers-Danlos syndrome type IV (EDS IV) is a rare but serious disorder of connective tissue that is characterized by the abnormal production or secretion of type III collagen. Experience with pregnant patients exhibiting this syndrome is limited. This report describes the successful management of a pregnancy in a woman with EDS IV that included activity restriction and complete bed rest after 32 weeks, use of 1-desamino-8-D-arginine vasopressin (DDAVP) before delivery to improve coagulation, and cesarean section before the onset of labor. The possibility of prenatal diagnosis based on genetic linkage studies also is discussed.
