Prenatal diagnosis and hemodynamic evaluation of Klippel-Trenaunay-Weber syndrome

Abstract
Klippel-Trenaunay-Weber syndrome is a rare congenital soft-tissue anomaly which is characterized by the presence of multiple hemangiomata, arteriovenous fistulas and limb hypertrophy. We report the ultrasound findings in two cases of early prenatal diagnosis at 17 and 18 weeks of gestation. The pathogenesis of the syndrome and involvement of the cardiovascular system are discussed.
