Objectives: Porto-sinusoidal vascular disease (PSVD) refers to a broad spectrum of histological lesions and phenotypic expressions. There are only a few reported pediatric cases in the literature. The primary outcomes of this study were to describe the phenotype of children with PSVD, to specify their mode of presentation and their clinical, biological, histological, and radiological characteristics as well as to identify their underlying etiologies. Methods: This is a descriptive, retrospective, and monocentric study of children followed at our reference center for rare vascular liver diseases. Results: Our study included 30 children ages 2months to 17.4years at the time of diagnosis. in most cases, the diagnosis was made incidentally without manifestation of any clinical symptom but rather on the finding of splenomegaly on physical examination (n = 9) or biological abnormalities (n = 13). In the other cases, the main presenting symptom was an upper gastrointestinal bleeding (n = 6). At the first visit, liver laboratory values were either normal (37%) or slightly disturbed. Anemia and/or thrombocytopenia associated with hypersplenism were found in 60% of patients. Liver biopsy was necessary for diagnosis. A total of 80% of cases had no identified etiology. After a median follow-up of 4.5 years, 33% had not developed portal hypertension (PHT) and we reported the first pediatric case of hepatocellular carcinoma in PSVD children. Conclusions: PSVD is responsible for nonspecific symptomatology with variable evolution sometimes marked by serious complications requiring invasive treatments or even liver transplantation. Regular monitoring is essential to prevent, detect, and treat complications.
