Klippel-Trénaunay-Weber Syndrome

Research output: Chapter in Book/Report/Conference proceedingChapter


Klippel-Trénaunay-Weber syndrome (KTWS) is characterized by a triad of cutaneous hemangiomas, hemihypertrophy, and vascular abnormalities. The prevalence of KTWS is 1: 100,000. The exact pathophysiology and genetic etiology of the disorder are unknown. Prenatal diagnosis using ultrasound has been reported. Diagnosis is based on limb hypertrophy with the association of subcutaneous cystic lesions. Postnatal treatment consists of symptomatic management.
