—A. L. de Medina et al published (Angiologia 2, 1962) an analysis of 165 patients who had been treated for vascular trauma during the period from 1945 to 1961. There were 182 arterial and 27 venous lesions, the majority of them caused by gun bullets. Dr. Medina and co-workers concluded that in vascular trauma immediate intervention is indicated, for not only does one find an aseptic field—the arterial and venous conditions are best then for reconstruction. Six hours after the onset of ischemia, the nerve cell may show functional alterations, and irreparable lesions may supervene. Such lesions, if not treated early, may produce false aneurysms and arteriovenous fistulae, and in that event correction is much more difficult.
