Patients with KTW syndrome may have atresia of the deep veins, as well as many abnormal venous pathways involving the deep and superficial venous systems. KTW syndrome can produce such severe venous insufficiency that the otherwise normal lymphatic system becomes overwhelmed by the amount of lymph production, which leads to secondary lymphedema.
