[Arterial thrombosis of the arm and hemorrhagic rectocolitis. Report of a case]. / Thromboses artérielles des membres supérieurs et rectocolite hémorragique à propos d'un cas.

Several cases of arterial thrombosis associated with inflammatory enterocolitis affections have been reported. In all but one case reported in the literature the outcome was favorable. A 40 year old woman developed thrombosis of the radial and ulnar arteries during an acute episode of ulcerative colitis. The course of the thrombotic lesions was irreversible and all fingers of the right hand had to be amputated. The corticotherapy as a possible predisposing factor for these thromboses is discussed, but their onset during an inflammatory episode suggests a role for the inflammatory enterocolitis. A thrombocytosis (807,000 platelets/mm3) could have predisposed to their onset, and in this case the hemostatic disturbances and fibrinolysis associated with the ulcerative colitis could have played a major role.
