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.
一项对20例行腔静脉开窗术患者的回顾性研究表明，50%的患者接受该手术是为了预防，50%是出于治疗目的。该手术后，5例患者持续存在腿部肿胀，2例发生深静脉血栓形成，2例出现肺栓塞，1例死于呼吸骤停。我们建议将腔静脉开窗术的应用局限于那些在充分抗凝的情况下已证实有肺栓塞的患者，或患有肺栓塞且有抗凝主要禁忌证的患者。
