Background : Acute superior mesenteric artery occlusion is a life-threatening disease that often has nonspecific symptoms. However, it should be suspected in those with known risk factors such as atrial fibrillation, cardiac thrombus or cardiac valvular disease.
Case Report : We reported two cases of acute thromboembolic occlusions of superior mesenteric artery that developed in acute cerebral infarction patients with confirmed atrial fibrillation.
Conclusions : Nonspecific symptoms of acute superior mesenteric artery occlusion should be closely monitored in acute cerebral infarction patients with atrial fibrillation, considering significance of early management of both vascular disease entities.
