Extra-hepatic portal vein thrombosis in children: Single center experience.

Aim of the study: We aimed to discuss our experience in management of children with extra-hepatic portal vein thrombosis (EHPVT).

Material and methods: This retrospective cohort study included 62 children with EHPVT. All patients' records were reviewed. The patients' socio-demographic data, post-natal history, disease presentation and clinical examination were collected. Data from laboratory investigations - complete blood count, liver function tests, renal function tests, abdominal ultrasound/Doppler studies, upper endoscopic findings and treatment regimens - were collected whenever available.

Results: Of the 62 patients, 62.9% were male and 37.1% were female. The mean age at disease presentation was 3.5 ±2.7 years. The main initial clinical presentation of the disease was hematemesis and/or melena (30 cases; 48.4%). History of umbilical catheterization (UVC) was present in 60% of cases. The thrombophilia profile was assessed in 17 patients, of whom 12 (70.6%) were found to have a coagulation disorder. Splenomegaly was present in 91.7% of the patients. Hematological abnormalities in the form of cytopenias were present in most cases. Ultrasound revealed the presence of collaterals in 76.2%. Upper endoscopy showed the presence of varices in 45 cases, all of which needed endoscopic intervention, while in 11 cases the varices were either low grade or absent and thus were subjected only to medical treatment with propranolol and 6 cases were lost to follow-up. Splenectomy was done in only one case and 2 cases underwent the Rex operation.

Conclusions: Variceal bleeding is the most common clinical presentation of EHPVT in children. UVC is still the main etiological factor of EHPVT in our cohort especially with presence of thrombophilic disorder.
