title: [Substantiation and varieties of complex surgical treatment tactics for pyo-necrotic forms of diabetic foot].
abstract: For the period from 1996 to 1998 in the Division of wounds and wound infection of A.V. Vishnevsky Institute of Surgery 92 patients with pyonecrotic forms of "diabetic foot" underwent thorough examination and treatment. The patients were divided into groups by the form of "diabetic foot": with pyonecrotic forms of "diabetic foot" without critical ischemia (group 1) and with it (group 2). In 18 patients of both groups the data of electron autoradiography were used to reveal peculiarities of the wound process. Group 1 patients had at admittance a large number of neutrophiles in various stages of destruction in biopsies of the wound. In patients of group 2 a great majority of the vessels in biopsies of the wound were in different stages of destruction with lost connections between their separate cells or some of their part absent. Separate cells (endotheliocytes and pericytes) which make up the walls of destroying vessels, were synthesizing RNA and were functionally active. In both groups, the studied parts of the wound before plastic repair of its defect usually represented as well developed granulation tissues with a number of microvessels and cells. Intensive synthesis of PNA in the cells of microvascular wall evidenced of their high functional activity, and the synthesis of DNA in them showed their ability for proliferation, i.g.--for growth. Thus, microangiopathy was reversible, and the solution of the problem of critical ischemia should be considered in the light of macroangiopathy. Thus, in patients of group 1 the cause of pyonecrotic damage consists in infection process, while in patients of group 2--in combination of infection with ischemia of the extremity. In both groups pyonecrotic disease of the extremity ruses at the background of severe disturbances of cellular immunity.
