Patient Data

Age: 22 years
Gender: Male

The superior mesenteric vein appears dilated. There is evidence of filling defect in the superior mesenteric vein and its tributaries due to an isodense material within the lumen of the veins suggestive of acute superior mesenteric vein thrombosis.

The thrombosis is extending from the spleno-portal venous confluence to the main tributaries of superior mesenteric vein.
There is mild mesenteric fat stranding noted.
Mild amount of free fluid noted in the dependent part of peritoneum.

Case Discussion

The superior mesenteric vein thrombosis is a well know complication of laparoscopic procedures, though a rare cause of intestinal ischemia. SMV thrombosis accounts for approximately 10% of all mesenteric ischemia.
