[Embryogenetic malformations of the inferior vena cava, and their manifestations in adults].

Five male patients with congenital anomalies of the inferior vena cava aged 20 to 43 were examined. The diagnosis and the level of aplasia were established on the basis of complex instrumental examination (duplex scanning of inferior extremity veins, pelvic veins, and retroperitoneal veins; computed and magnetic resonance tomography of the abdominal cavity; pelvic phlebography; retrograde cavagraphy). Together with inferior vena cava anomalies, other malformations such as pulmonary arterial stenosis or duplication of renal collector system were diagnosed in two patients.

[Features of correction of phosphate-calcium metabolism disorders in terminal renal failure].

Mineral metabolism was studied in 27 hemodialyzed patients with terminal chronic renal failure (CRF). Because of progressing hyperparathyroidism the initial treatment included calcium drugs, active forms of vitamin D (videchol, oxidevit), almagel, bicarbonate hemodialysis and hemosorption. The condition improved in 8 and stabilized in 12 patients.

[The potentials of sympathectomy in treating lesions of the lower extremities in diabetics].

Investigations of the system of general and regional hemostasis in patients with diabetes mellitus and the IVth degree of ischemia of lower extremities have established the development of chronic hypercoagulation-thrombotic forms of disseminated intravascular blood coagulability. Prophylactics of thrombotic complications allows to avoid high amputations in 80% of the patients, to make only necrectomies, small amputations and dermoplasty.
