Abstract

PURPOSE: To assess the success of direct percutaneous puncture of the recanalized paraumbilical vein (RPUV) for access and visualization of the portal vein (PV) to guide transhepatic puncture during transjugular intrahepatic portosystemic shunt (TIPS) creation. The predictive value of successful catheterization based on preprocedural vein diameter was analyzed. MATERIALS AND METHODS: A retrospective review of all TIPS procedures from 2002 to 2008 performed at a single institution was conducted, and a subset of procedures in which portal venography was attempted via the paraumbilical vein were identified. In this subset, TIPS outcomes and diameters of the RPUV near the skin puncture site and left PV junction were measured and analyzed with a two-tailed Student t test. RESULTS: During the study period, 114 TIPSs were created. RPUV punctures were found in 22 patients (19.3%) and portal venography was successful in 14 of the 22 patients (64%), all without complications. In the remainder (n = 8), access via the RPUV failed secondary to a small vein diameter (<0.3 cm; n = 3), moderate to severe vessel tortuosity (n = 4), and distal thrombosis (n - 1). Puncture, catheterization, and portal venography was successful when the paraumbilical vein measured a mean of 0.75 cm at the skin and a mean of 0.84 cm at the junction with the left PV when analyzed against the failed attempts. CONCLUSIONS: Portal venography via the RPUV is a feasible and probably safe alternative to other methods of PV opacification during TIPS procedures.
