[Percutaneous balloon angioplasty in the treatment of membranous obstruction of the inferior vena cava].
Percutaneous transluminal angioplasty (PTA) was performed with Inoue balloon catheter in 20 patients with membranous obstruction of the inferior vena cava (MOVC) including 4 postoperative recurrent cases. 9 patients had complete and 11 had incomplete MOVC. The thickness of the membrane or web measured 1-5mm. one patient died of massive pulmonary embolism after successful PTA. The remaining 19 patients remained asymptomatic during 6-38 months. Two-dimensional ultrasonograms showed no recurrence of MOVC or thrombosis. The caval diameter at the site of MOVC increased from 1.7 +/- 1.5 to 20.3 +/- 2.6mm (P < 0.0001), and the caval pressure below the MOVC decreased from 340 +/- 76 to 160 +/- 72mm H2O (P < 0.0001), respectively.
