A case of thrombosis of the superior mesenteric vein occurring in a young woman taking oral contraceptives: full and fast resolution with low molecular weight heparin.

Mesenteric venous thrombosis (MVT) is an unusual site of deep venous thrombosis. Little is known about risk factors of MVT, but available data seem to confirm a pathogenetic role of acquired thrombotic risk factors as well as inherited thrombotic risk factors. However, few cases on the association of MVT with oral contraceptive use have been described. We here report a case of MVT in a woman on oral contraception with fine and complete resolution after a fast diagnosis with abdominal ultrasound imaging and prompt therapy based on low molecular weight heparin.
