Abstract
The objectives of treatment in iliofemoral venous thrombosis are to prevent fatal pulmonary embolism, further swelling of the leg with development of phlegmasia caerulea dolens and the severe post-thrombotic syndrome, by preservation of venous patency and normal valves. The experience of thrombectomy and temporary AVF are presented in 155 patients where technical details of management are emphasized. A new technique with percutaneous closure of the AVF after six weeks is described. No patient died due to fatal pulmonary embolism during or immediately after surgery. In a randomized study comparing surgery with conventional anticoagulant treatment follow-up venography of the iliofemoral segment demonstrated excellent results in 76% of the operated group and 36% in the conservatively treated group, while venography of the femoropopliteal segment revealed an occlusion in about one-third of the patients in both groups. Of the patients who had an open femoropopliteal segment it was noted that 52% in the surgical group and 26% in the conservative group had preserved valves with no reflux.
