Complete thrombosis of the superior mesenteric vein extending to the portal-splenic confluence, with mesenteric congestion.
Case Discussion
Surprisingly little signs of abnormal small bowel despite complete thrombosis of the superior mesenteric vein. There is likely collateral venous flow allowing relatively normal perfusion of the small bowel to continue, and resulting in more insidious onset of symptoms.
