A vena caval umbrella was implanted in twenty-eight patients for the prevention of recurrent pulmonary embolism. Eighteen of these patients were catastrophically ill at the time of reimplantation. Thirteen patients died after implantation, one from a recurrent pulmonary embolus originating in the vena cava. There have been two additional recurrent nonfatal emboli. Three of the thirteen long-term survivors had significant lower extremity edema. Our experience and that of others indicates that the inferior vena caval umbrella is comparable to other methods of incomplete interruption in terms of effectiveness, morbidity, and mortality. Its unique technical advantage is the simplicity of insertion in severely ill patients in whom abdominal surgery is undesirable.
为预防复发性肺栓塞，对28例患者植入了腔静脉滤器。其中18例患者在再次植入时病情严重。13例患者植入后死亡，1例死于源于腔静脉的复发性肺栓塞。另有2例非致命性复发性栓塞。13例长期存活者中有3例出现明显的下肢水肿。我们以及其他人的经验表明，在下腔静脉滤器的有效性、发病率和死亡率方面，其与其他不完全阻断方法相当。其独特的技术优势在于，对于不宜进行腹部手术的重症患者，植入操作简便。
