Percutaneous transluminal angioplasty (PTA) was performed with the Inoue balloon catheter in nine patients with membranous obstruction of the inferior vena cava (MOVC) between November 1988 and April 1991. There were five men and four women, aged 30.8 +/- 8.5 years. Two patients had had previous surgical treatment. Three patients had complete and six had incomplete MOVC. The caval pressure below the MOVC was 24.0 +/- 5.6 and 11.8 +/- 5.3 mm Hg (p less than 0.0001) before and after PTA, respectively. The caval diameter at the site of MOVC increased from 1.5 +/- 1.7 to 20.3 +/- 2.6 mm (p less than 0.0001), and the maximal caval diameter below the MOVC decreased from 28.7 +/- 12.9 to 19.8 +/- 9.9 mm (p = 0.006), before and after PTA, respectively. One patient died of massive pulmonary embolism following successful PTA. All the other eight patients remained asymptomatic during an 18.5 +/- 11.5 months (range 3.5 to 32) follow-up period. Two-dimensional ultrasonograms showed no recurrence of MOVC. We conclude that PTA with the Inoue balloon catheter is an effective and safe alternative to surgical treatment of MOVC.
1988年11月至1991年4月期间，我们使用Inoue球囊导管对9例下腔静脉膜性梗阻（MOVC）患者进行了经皮腔内血管成形术（PTA）。其中男性5例，女性4例，年龄30.8±8.5岁。2例患者曾接受过手术治疗。3例患者为完全性MOVC，6例为不完全性MOVC。PTA术前和术后MOVC下方的腔静脉压力分别为24.0±5.6和11.8±5.3 mmHg（p<0.0001）。PTA术前和术后，MOVC部位的腔静脉直径从1.5±1.7增加至20.3±2.6 mm（p<0.0001），MOVC下方的最大腔静脉直径从28.7±12.9减小至19.8±9.9 mm（p = 0.006）。1例患者在PTA成功后死于大面积肺栓塞。在18.5±11.5个月（范围3.5至32个月）的随访期内，其余8例患者均无症状。二维超声心动图显示MOVC无复发。我们得出结论，使用Inoue球囊导管进行PTA是MOVC手术治疗的一种有效且安全的替代方法。
