[Klippel-Trenaunay-Weber syndrome].

Klippel-Trenaunay syndrome is an inherited disorder that is known to affect the venous system. Besides venous pathologies, arterial stenosis and aneurysmatic dilatations are extremely rare. In this report, we present a 7-year-old boy with Klippel-Trenaunay-(Weber) syndrome who developed iliac and femoral artery aneurysms and stenosis at different levels in his lower limb.
