Seattle (WA): University of Washington, Seattle; 1993-2020. The vascular malformation in the Parkes-Weber syndrome is an arteriovenous malformation, which grows in proportion to the growth of the child and also in relation to the hemodynamic changes such as increased blood flow, causing vessel dilatation, obstruction and thrombosis. Parkes-Weber syndrome resembles Klippel-Trenaunay syndrome in that it is associated with a combination of abnormal vessels characterized by a patchy capillary vascular malformation (port wine stain) on the surface. Clinical or radiologic findings of Parkes-Weber syndrome could be differentiated with that of predominent venous malformations with arerior-venous fistula.

Parkes Weber syndrome is a disorder of the vascular system, which is the body's complex network of blood vessels. Klippel-Trenaunay syndrome (KTS) presents with a classic triad of bone and soft-tissue hypertrophy, cutaneous capillary hemangioma (port wine stain), and congenital varicose veins. There was no high output cardiac failure in this case. Parkes Weber syndrome is similar to KTS except that an arteriovenous malformation (AVM) occurs in association with a cutaneous capillary malformation and skeletal or soft-tissue hypertrophy. The hallmarks of both PKWS and CM-AVM are the presence of fast-flow vascular malformations and capillary malformations (CM). children. The absence of high flow arteriovenous malformations is characteristic of this syndrome . The exact pathophysiology and genetic etiology of the disorder are unknown.
