Superior masenteric vein thrombosis

A 43 year-old woman presented with severe non-specific abdominal pain of 1-week duration. She was on oral contraceptive pills for the past 6 years. Clinically patient appeared ill with no specific abnormal physical sign. Moderate amount of free fluid in the peritoneal cavity on ultrasound prompted an urgent abdominal computed tomography (CT) scan, which revealed thrombosis of the superior mesenteric vein. Further investigations revealed a hypercoagulable state with protein C deficiency. Patient responded well to anticoagulation and supportive therapy. One month later patient readmitted with vomiting and signs of intestinal obstruction. Barium study revealed a moderately long tight stricture at mid jejunum with proximal dilation. A by-pass surgery was carried out. She was well at 3 months follow-up.
