Five transvenous instrumental membranotomies were performed in four patients with membranous obstruction of the hepatic segment of the inferior vena cava. Membranotomy was done with a specially designed instrument similar to a Tubbs' dilator, which was inserted through femoral or the right internal jugular veins. Pressure gradients across the membrane disappeared after membranotomy and the release of the stenosis was confirmed by angiography and ultrasonography. One patient needed a second membranotomy because of recurrent stenosis 7 years after the initial procedure.
对4例下腔静脉肝段膜性梗阻患者实施了5次经静脉器械膜切开术。膜切开术使用一种专门设计的类似塔布斯扩张器的器械，通过股静脉或右颈内静脉插入。膜切开术后，膜两侧的压力梯度消失，血管造影和超声检查证实狭窄已解除。1例患者在初次手术后7年因狭窄复发需要再次进行膜切开术。
