Thrombose veineuse mésentérique et cave inférieure : CIVD et/ou mutation G 20210 A du gène de la prothrombine ?

The authors report the case of a 30-year-old man who died from pulmonary embolism and multiorgan failure caused by mesenteric and inferior vena cava thrombosis. The patient was found heterozygous for the prothrombin gene variant (G 20210 A). The family study showed the same asymptomatic anomaly in his brother. This recently described mutation is associated with an increased risk for venous thrombosis. The investigations and treatment of mesenteric venous thrombosis are discussed.
