After TIPS: relapse of ascites requiring at least 2 paracenteses or persistence after 2 months will be considered as treatment failure. A hemodynamic and angiographic control will be performed. Patients will be treated by refection of the shunt. If severe encephalopathy occurs and persists despite treatment, the diameter of the shunt should be decreased or the TIPS occluded. Total occlusion of the shunt or relapse of ascites after the reduction of its diameter will be also considered treatment failures.
