Diversion Venography-A Modified Technique in Klippel-Trenaunay Syndrome: Initial Experience

PURPOSE: To evaluate an initial experience with diversion venography, a modified venographic technique, to assess the deep venous system in patients with Klippel Trenaunay syndrome (KTS). MATERIALS AND METHODS: Eight patients with KTS underwent diversion venography of the affected lower extremities. The technique of diversion venography included the use of multiple methods to divert blood flow into the deep venous system, such as application of multiple tourniquets, cannulation of the tibial and popliteal veins, multiple imaging projections, and temporary endoluminal occlusion of the lateral venous system. All studies were done under general anesthesia before surgical or interventional procedures. RESULTS: The technique of diversion venography was successful in opacifying the deep venous system in all eight patients studied. No complications were encountered. CONCLUSIONS: Diversion venography successfully visualizes the deep venous system in patients with KTS. This can potentially expand the treatment options for these patients.
