Post-traumatic superior mesenteric venous thrombosis with subsequent extension to the portal vein.

Acute superior mesenteric vein thrombosis was first described in 1935 by Warren and Eberhardt. It is a potentially life-threatening condition, as it can lead to bowel ischemia and, ultimately, infarction. Its etiology may be primary or secondary to acquired prothrombotic conditions. Early recognition of mesenteric venous thrombosis is important, but can be challenging due to its nonspecific clinical presentation. Contrast-enhanced computed tomography is currently the gold standard for diagnosis. Systemic anticoagulation and surgical resection of the necrotic segment are the two main treatments. Here, we describe a case of acute post-traumatic superior mesenteric vein thrombosis, which was treated with systemic anticoagulation and resection of the ischemic bowel segment, with subsequent extension of the thrombosis to the portal vein.
