| Abstract: | A retrospective study of 20 patients who underwent vena caval fenestration showed that in 50% of the patients the procedure was done for prophylaxis and in 50% it was done for therapeutic reasons. After this procedure five patients had persistent leg swelling, two had deep venous thrombosis, two had pulmonary emboli and one died of a respiratory arrest. We recommend limiting the use of vena caval fenestration to those patients who have verified pulmonary embolism while adequately anticoagulated or patients who have pulmonary embolism and a major contraindication to anticoagulation. |
