Ventriculoperitoneal (VP) shunt failures are common and are frequently associated with an obstruction of the peritoneal tube. This study aimed to explore the possible causes of peritoneal tube obstruction, which are largely unknown. From January 1981 to June 2018, we performed VP shunting in 646 patients with hydrocephalus. Among the procedures performed, 148 shunt revision procedures were performed in 98 patients with VP shunt failure. Of the study participants, 64 (43.2%) patients were diagnosed with peritoneal tube obstruction and five patients developed sheath formation that obstructed the end of the peritoneal tubes. Sheath formation around the peritoneal tube is a possible cause of VP shunt dysfunction.
脑室腹膜（VP）分流失败很常见，通常与腹膜管阻塞有关。本研究旨在探讨腹膜管阻塞的可能原因，这些原因在很大程度上尚不清楚。1981 年 1 月至 2018 年 6 月，我们对 646 例脑积水患者进行了 VP 分流术。在进行的手术中，98 例 VP 分流失败患者进行了 148 次分流修复术。在研究参与者中，64 名（43.2%）患者被诊断为腹膜管阻塞，5 名患者出现了鞘形成，阻塞了腹膜管的末端。腹膜管周围的鞘形成是 VP 分流功能障碍的一个可能原因。
