Mesenteric venous thrombosis

Symptoms: In most cases, mesenteric venous thrombosis is a slowly progressive process characterized by chronic abdominal pain, which is at times worse after eating. Less commonly, acute thrombosis of the mesenteric veins can lead to rapid progression of symptoms with severe, escalating abdominal pain, sometimes accompanied by vomiting and diarrhea. Signs and tests: CT scan is the diagnostic tool of choice for mesenteric venous thrombosis, and can outline the extent of thrombosis and the degree of vascular compromise to the intestine. Ultrasound of the abdomen and mesenteric veins is also used to determine the presence of clot in the veins.
