A Rare Cause of Acute Abdomen: Thrombosis in the Ileocolic Branch of the Superior Mesenteric Vein

Superior mesenteric vein thrombosis is a rare cause of acute abdomen. Patients usually complain of non-specific abdominal pain, which may show progress with secondary complaints, such as nausea, vomiting, and hematochezia. Mesenteric vein thrombosis has a mortality rate of 15% to 40%; early diagnosis plays an important role in treatment. An 80-year-old male patient presented at the Near East Universiry emergency department with complaints of fever and abdominal pain, underwent contrast-enhanced abdominal computed tomography, and was diagnosed with thrombosis in the ileocolic branch of the superior mesenteric vein. The complaints were treated with low molecular weight heparine (LMWH), and surgical intervention was not necessary.
