Proximal arterial dilatation developing after surgical closure of long-standing posttraumatic arteriovenous fistula.

Concomitant discovery of long-standing arteriovenous fistula (AVF) and proximal dilatation is commonplace whereas the disclosure of proximal arterial dilatation several years after closure of AVF is much more surprising and less often described. The goal of this study was to call attention to this late complication, to evaluate its prevalence, and to describe the mechanism and outcome after treatment. Six new observations were added to 11 cases already published in the literature.

[Thrombogenic thrombopenia induced by heparin].

Three cases of heparin induced thrombotic thrombocytopenia are reported. Pathogenesis, clinical and biological manifestations as well as treatment are reviewed. Treatment consisted in replacing the heparin by a vitamin K antagonist or a low molecular weight heparin.
