Idiopathic superior mesenteric vein thrombosis leading to gangrenous ileum: A case report

This case underscores that idiopathic SMVT, although rare and often diagnostically challenging, can rapidly progress to life-threatening bowel gangrene even in the absence of known risk factors. Timely diagnosis using contrast-enhanced CT and a multidisciplinary approach-including prompt surgical intervention and postoperative anticoagulation-are critical to improving survival and reducing long-term morbidity. This case reinforces the importance of maintaining a high index of suspicion and implementing early, coordinated management in suspected mesenteric ischemia.
