The long-term safety and clinical efficacy were assessed.</p><p><strong>Results: </strong>A pre-emptive TIPS was performed on seven patients with a mean age of 9.2 years (± standard deviation: 2.2).

No variceal bleeding was observed during the median follow-up of 9 years (IQR 8.1-12.9). In two patients with advanced PHT and rapidly progressive liver disease, severe thrombocytopenia could not be stopped. Subsequent liver transplantation revealed biliary cirrhosis in both patients. In the remaining patients with early PHT and milder porto-sinusoidal vascular disease, symptomatic hypersplenism did not occur, and liver function remained stable until the end of the follow-up.
