Mesenteric vein thrombosis triggered by blunt abdominal trauma in a patient with the primary antiphospholipid syndrome.

The antiphospholipid syndrome is defined by the presence of autoimmune antiphospholipid antibodies in serum together with venous, arterial or small-vessel thrombosis and/or morbidity with pregnancy. Superior mesenteric vein thrombosis represents a rare complication associated with this syndrome; triggering events such as surgical procedures, drug administration and anticoagulation withdrawal have been reported. We describe a case of superior mesenteric vein thrombosis triggered by blunt abdominal trauma in a 47-year-old man with the primary antiphospholipid syndrome.

Gastrointestinal leiomyoma and von Recklinghausen's disease: mesenteric angiography demonstrative of a rare association. Report of a case.

We report a 51-year-old woman with known neurofibromatosis of von Recklinghausen, who presented twice with melena, caused by a jejunal leiomyoma. The diagnosis was made by arteriography and confirmed by surgery. In order to exclude an intestinal smooth muscle tumour we believe that mesenteric angiography should be the initial procedure of choice in patients with neurofibromatosis presenting with a gastrointestinal bleeding.
