Massive inferior mesenteric vein - portal hypertension

Case contributed by Dr Chris O'Donnell

Presentation

Presents with acute lower abdominal pain, no history of liver disease

Patient Data

Age: 85
Gender: Male

Grossly cirrhotic liver and splenomegaly with a massively enlarged inferior mesenteric vein entering the pelvis associated with mutiple collaterals communicating with the left iliac vein

Case Discussion

One of the common porto-systemic collateral pathways that allows for decompression of raised portal venous pressure is the superior rectal vein (arising from the inferior mesenteric vein) entering the upper anal canal producing haemorrhoids. In this case there is an unusual anastomosis between inferior mesenteric vein branches and the left iliac vein
