Aims: To present two cases of thrombosis of the splanchnic veins, which is considered a possible fatal cause of intestinal ischemia, with the portal and superior mesenteric veins being the most affected. To discuss the etiological possibilities and emphasize the importance of using imaging exams for the definitive diagnosis. Case Description: Two women with splanchnic venous thrombosis showed nonspecific clinical manifestations. In the first case, the main symptoms were abdominal pain, bloody diarrhea, abdominal distension and nausea. In the second case, the patient presented with vague abdominal pain, anorexia and hypotension. In both cases the diagnosis was established by computed tomography.
