In adults, mesenteric venous thrombosis with extension into the portal system is a known complication of total proctocolectomy with pouch ileoanal anastomosis. Although frequently reported in adults, this complication is rare in pediatric patients undergoing this operation. We report 2 cases of adolescent patients with ulcerative colitis who experienced portal vein thrombosis after this procedure. Both were treated with systemic anticoagulation therapy with complete resolution of their clots. We recommend that mesenteric/portal venous thrombosis be considered in the differential diagnosis in any child presenting with fever, abdominal pain, and leukocytosis after restorative proctocolectomy with ileal pouch anastomosis and that imaging obtained to evaluate abdominal complaints in this population be directed toward ruling out this complication.
Introduction: Hepatic artery pseudoaneurysm (HAP) is a rare and potentially life-threatening condition associated with high mortality. This study aims to review the etiology, clinical manifestations, management, and outcomes of patients diagnosed and treated for HAP at the Mayo Clinic.
Methodology: This study was a retrospective chart review of medical records for patients diagnosed and treated for hepatic artery pseudoaneurysm (HAP) at the Mayo Clinic (Florida, Minnesota, and Arizona) between September 1, 1998, and June 30, 2022.
We report a case of an 87-year-old female with a ruptured hepatocellular carcinoma (HCC). She presented with sudden epigastric and right upper abdominal pain. The physical examination revealed mild tenderness in the right upper abdomen, a positive Murphy's sign, and no jaundice.

Background: Portal vein system-specific risk factors contributing to portal vein thrombosis in cirrhosis are poorly investigated.
Aims: To quantify contact system and intrinsic pathway activation in peripheral compared to portal venous blood in patients with decompensated cirrhosis.
Methods: Adult patients with cirrhosis undergoing transjugular intrahepatic portosystemic shunt underwent simultaneous blood sampling from a peripheral vein and the portal vein.
Purpose: To establish the normal ranges of the main portal vein (MPV), left portal vein (LPV), and right portal vein (RPV) diameters in children and adolescents using abdominal contrast-enhanced CT.
Methods: We retrospectively enrolled children and adolescents (under 19 years) who underwent abdominal contrast-enhanced CT examinations in our hospital between January 2018 and January 2024. Subjects with conditions potentially affecting the portal vein diameter were excluded.
