The surgical treatment of predominantly venous defects

The predominantly venous defects consist of the truncular forms, as there is aplasia or obstruction in the truncular dilatation; and they consist of the extratruncular forms as there are the infiltrating ones and the limited ones, according to the Hamburg classification. The web or membranous obstruction of the inferior vena cava (IVC), dilatation or aneurysm of the jugular vein, infiltrating "cavernous angioma" and localized venous defects are the main lesions of those classifications reported in this communication. Jugular dilatation and localized extratruncular lesions have had good therapeutic results. Webs of the IVC can be treated by membranectomy, either by finger, transcardially, or balloon, percutaneously, and cavo- or mesoatrial shunt; however, membranectomy, along with cavoplasty as a radical treatment for such an entity, is advocated by the authors. The infiltrating extratruncular form is the unsolved important issue concerning its thorough resection. Skin graft taken from a resected tissue mass through a reversal split thickness skin graft by a drum type dermatome, removal of the lesion along with muscle layer(s), and staged operations are recommended.
