[Evaluation of the results of reconstructive operations in patients with occlusive diseases of the abdominal aorta and its branches].

The article deals with the results of studying regional microcirculation in 550 patients with chronic arterial insufficiency. Radioisotope study of blood flow in the muscles with isotopes 131I or 133Xe before and after muscular exertion, morpho-histological++ study of biopsies from a skeletal muscle, histochemical and ultrastructural study of the microcirculatory channel were carried out. Analysis of the findings made it possible to distinguish, according to the changes in circulation in the tissues, three clinical groups of patients (compensated, subcompensated, and decompensated), to determine the indications and contraindications for various types of reconstructive operations, and to prognosticate with high authenticity the outcome of the disease.
