Overview

Case report demonstrates severe portal hypertensive bleeding from vascular anomalies in a young adult, highlighting diagnostic challenges.

Key Points

  • To describe a rare case of portal hypertension due to splanchnic arteriovenous communication and its associated complications.
  • Case report of a 20-year-old man presenting with gastrointestinal bleeding and ascites.
  • Evaluation included advanced angiographic imaging to identify vascular anomalies.
  • Multidisciplinary management approach was undertaken, involving endoscopy and interventional radiology.
  • Presentation included acute upper gastrointestinal bleeding and ascites.
  • Evaluation revealed a superior mesenteric artery pseudoaneurysm communicating with the superior mesenteric vein.
  • The case resulted in an aneurysmal dilatation of the portal vein and significant portal hypertension.
