[THE TREATMENT OF PATIENTS FOR ULCERATIVE-NECROTIC DEFECTS IN CHRONIC ISCHEMIA OF THE LOWER EXTREMITY TISSUES, USING BIOTECHNOLOGICAL METHODS].

The results of treatment of 53 patients, suffering "unreconstructable" affection of the lower extremities (LE) arteries and ulcerative-necrotic defects in their distal parts tissues, were analyzed. In 33 patients (the main group) the allotted mononuclear cells fraction, the bone marrow and the plasm, enhanced by thrombocytes, were applied, using multiple injections along a perimeter and into the bottom of the ulcerative-trophic defect in combination with autotransplantation of the bone marrow aspirate into the ischemized tissues--the shin muscles; in 20 patients (the comparison group)--the autotransplantation of the bone marrow aspirate was accomplished into the ischemized tissues--the shin and the foot muscles. In terms up to 3 mo postoperatively a clinical improvement in the main group was noted in 25 (75.

[Application of autologous aspirates as well as multipotent stromal cells of the bone marrow and adipose tissue in vascular surgery].

Basing on experiments, performed on laboratory animals, and on the literature data, there was proved stimulating influence of transplantation of stromal cells, residing in adipose tissue, in a kind of stromal-adiposal fraction towards angiogenesis and reparative processes in tissues in ischemic conditions. There was elaborated and introduced the tactics of treatment in patients, suffering chronic ischemia of the lower extremities tissues, using combined methods of surgical treatment, including the bone marrow aspirate (BMA) autotransplantation into the ischemized tissues, the rotation ostheotrepanation, reconstructive and endovascular interventions on proximal segment of the extremity. The efficacy and potential of application of the BMA and adipose tissue was proved in the treatment of patients, suffering ischemia of the upper extremities tissues, caused by thromboobliterating affection of peripheral vascular bed.

[Alternative method of surgical treatment for aortic arteritis in non-repairable forms of vessels damage].

The purpose of the work--the choice of optimal treatment tactics of patients at the extremity tissue ischemia due to nonspecific aortoarteritis (NA). In the surgical treatment of patients with NA, particularly with concomitant peripheral lesions, and to a greater degree of terminal arterial bed, significantly limited the possibility of direct revascularization. Conservative treatment and subthoracal sympathectomy are ineffective.

[The upper extremities revascularization in patients with brachial artery thrombosis due to its chronic damaging by crutches: new approaches to the treatment].

An optimal tactics of treatment of patients, suffering the upper extremities (UE) ischemia, caused by arterial thrombosis, occurred due to subclavian artery damage in those patients, who apply crutches for a long period of time, was elaborated. In modern medicine in patients with the UE arterial bed thrombosis with affection of its peripheral, and more in terminal, portion the possibilities of direct revascularization performance are significantly restricted, especially in patients, suffering from constant mechanical injury of armpit and its vascular content, caused by crutches. Application of the method, consisting of automyelotransplantation of the bone marrow aspirate, have permitted to regulate the disorders of microhemodynamics, using stimulation of angiogenesis and development of a collateral blood flow.
