PORTAL AND MESENTERIC THROMBOSIS IN PROTEIN S (pS) DEFICIENCY.

Portal and/or mesenteric thrombosis is a rare occurrence, and often an underlying hypercoagulable slate can be found. We describe a case in which a mesenteric infarction due to mesenteric venous thrombosis occurred as the first manifestation of an inherited type I deficiency of protein S, whereas signs of portal thrombosis emerged later.
