Mesenteric vein thrombosis associated with oral contraceptive administration during pregnancy.

A case is reported of mesenteric venous occlusion in a young woman who by mistake received oral contraceptives during pregnancy. A resection of the damaged small bowel was performed followed by an end to end enteroenterostomy. It is suggested that the hypercoagulable state normally found in pregnancy was aggravated by the hormonal intake and lead to the mesenteric vein thrombosis.
