Requirements for a method of transvenous inferior vena cava interruption.
Six requirements were defined that would characterize a safe and effective technique of transvenous inferior vena cava (IVC) interruption: (1) the instrument should be placed transjugularly under local anesthesia; (2) the instrument should have "built-in" capability for venography; (3) the technique should produce complete occlusion of the IVC; (4) the occluder must adapt to any variable in IVC diameter; (5) the intracaval device must have no sharp edges, pins, or points; and (6) the technique must permit simultaneous heparin therapy. These specifications were met by a catheter-delivered detachable balloon that could be inflated to any needed diameter. This technique was used in 96 patients, with a follow-up period to ten years. Time and experience confirm the validity of the six requirements for a safe and effective technique.
