Nadroparin Versus TIPS in Cirrhotic Patients With Refractory Asymptomatic PVT

Using the transjugular approach, TIPS was created under local anesthesia. The first branch of the left or right portal vein (PV) was punctured by RUPS-100 set guided by digital subtraction angiography. After successful access into PV, direct portography was performed and all visible varices and/or concurrent spontaneous portosystemic shunts (SPSS) were embolized with coils and n-butyl cyanoacrylate. A polytetrafluoroethylene-covered stent (Viatorr Endoprosthesis, GORE and Associates, Flagstaff, Arizona, USA) with a diameter of 8 mm was implanted and fully dilated.

Nadroparin calcium will be subcutaneously injected with the dose of 85IU/kg q12h
