Extrahepatic portal vein obstruction has been reported to be associated with tumors of liver, bile ducts and pancreas. We report two cases, one with gastric leiomyosarcoma and another with Non Hodgkin’s lymphoma, complicated by portal vein block and presenting with gastric variceal bleeding. Portal vein block in both cases was due to direct vascular infiltration. Development of portal hypertension posed difficulties in management.

Outflow System

Closures in the splanchnic venous system (SVS) represent a broad medical problem. Anatomically, individual or even multiple sections of SVS may be affected at the same time. Main sections of SVS include the venous liver outflow system, the portal vein, and the upper mesenteric vein and its basin. Thrombosis is clearly the predominant cause of closure. The closures can present as acute, subacute, chronic occult or chronic manifest. The main pathological and anatomical units are the Budd-Chiari syndrome (BCS), extrahepatic portal vein obstruction (EHPVO) and mesenteric vein thrombosis (MVT). Advanced laboratory, imaging and intervention methods substantially modify the approach to prevention, diagnosis and treatment; surgical approach also plays a role. The problem of SVS closures is interdisciplinary.

Abstract Background Extrahepatic portal vein obstruction (EHPVO) is the most important cause of hematemesis in children. Intrahepatic left portal vein and superior mesenteric vein anastomosis, also known as meso-Rex bypass (MRB), is becoming the gold standard treatment for EHPVO. We analyzed the value of preoperative computed tomography (CT) in determining whether MRB is feasible in children with EHPVO. Results We retrieved data on 76 children with EHPVO (50 male, 26 female; median age, 5.9 years) who underwent MRB (n = 68) or the Warren procedure (n = 8) from 2013 to 2019 and retrospectively analyzed their clinical and CT characteristics. The Rex recess was categorized into four subtypes (types 1–4) depending on its diameter in CT images. Of all 76 children, 7.9% had a history of umbilical catheterization and 1.3% had leukemia. Sixteen patients (20 lesions) had associated malformations. A total of 72.4% of Rex recesses could be measured by CT, and their mean diameter was 3.5 ± 1.8 mm (range 0.6–10.5 mm). A type 1, 2, 3, and 4 Rex recess was present in 9.2%, 53.9%, 11.8%, and 25.0% of patients, respectively. MRB could be performed in patients with types 1, 2, and 3, but those with type 4 required further evaluation. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of CT were 100%, 83.8%, 42.1%, 100%, and 85.5%, respectively. Conclusions Among the four types of Rex recesses on CT angiography, types 1–3 allow for the performance of MRB.

ABSTRACT Objective: This study aims to evaluate dietary intake, nutritional status, and growth rate in children and adolescents with extrahepatic portal vein obstruction and portal hypertension. Methods: Outpatients aged 1-18 years, diagnosed with extrahepatic portal vein obstruction and portal hypertension, who had no associated diseases, and who had not been subjected to a venous shunt were included in this study. Two evaluations were carried out in this study: an initial (evaluation 1) and a final evaluation (evaluation 2), with a three-month minimum interval between them. In each evaluation, dietary intake was analyzed comparing the results with recommended energy intake using the Harris & Benedict equation and participants’ anthropometric data, such as weight, height, mid-arm muscle circumference, weight-for-age, height-for-age, and body mass index-for-age, based on the World Health Organization 2006 standards. Results: A total of 22 patients participated in this study. There was a significant improvement in weight, height, body mass index, and mid-arm muscle circumference measurements (p<0.001; p<0.001; p<0.017; p=0.0018 respectively) and in the relationship between dietary intake and energy recommended energy intake, according to the Harris & Benedict equation (p=0.0001) from the first and second evaluation. Conclusion: Extrahepatic portal vein obstruction and portal hypertension were not shown to be factors predisposing to malnourishment.
