Early obstruction of the venous tubing is a frequent complication after peritoneovenous (PV) shunting for ascites in cirrhosis and results in a high incidence of shunt failure. A titanium catheter tip, developed because of this material's thromboresistance, was employed in 13 consecutive cirrhotic patients receiving a LeVeen shunt for intractable ascites. While the mean interval before shunt occlusion was 4 +/- 3 months in our previous studies, none of the patients in the present series had venous catheter occlusion during follow-up, which averaged 8 +/- 2 months. The use of titanium in the venous tubing of PV shunts may significantly prolong the patency and function of these devices.
早期静脉导管阻塞是肝硬化腹水患者行腹腔-静脉（PV）分流术后常见的并发症，导致分流失败的发生率很高。由于钛这种材料具有抗血栓形成特性而研发的钛质导管尖端，被应用于连续13例接受LeVeen分流术治疗顽固性腹水的肝硬化患者。在我们之前的研究中，分流闭塞前的平均间隔时间为4±3个月，而在本系列研究中，随访期间平均8±2个月，无一例患者出现静脉导管闭塞。在PV分流术的静脉导管中使用钛可能会显著延长这些装置的通畅时间和功能。
