[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. In three or 60% of the patients the disease had first manifested by the clinical picture of peripheral thrombosis (shin and femoral edema); fever, chill and subsequent edema of both legs had been first manifestations in two patients. Aplasia of the infrarenal segment of the inferior vena cava was revealed in two patients; in other two patients aplasia of the infrarenal, renal, and partly suprarenal segments of this magistral vessel was found; in one patient the whole vein was aplastic except a small part of the suprarenal segment, where the hepatic veins and the right suprapolar renal vein flew into. To establish an early diagnosis of a congenital inferior vena cava anomaly, the protocol of examination of patients with venous diseases should include ultrasound mapping of the suprarenal and infrarenal segments of the vena cava; in cases of agenesia it should include computed and magnetic resonance tomography and retrograde cavagraphy.

[Features of correction of phosphate-calcium metabolism disorders in terminal renal failure]. / Osobennosti korrektsii narushenii fosfatno-kal'tsievogo obmena pri terminal'noi pochechnoi nedostatochnosti.

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. Conservative treatment was ineffective in 7 patients who consequently underwent total (4 cases) or subtotal (3 cases), parathyroidectomy. The response was achieved in 3, stabilization in 3, the disease advanced in 1 patients.

[The potentials of sympathectomy in treating lesions of the lower extremities in diabetics]. / Vozmozhnosti simpatéktomii v lechenii porazhenii nizhnikh konechnostei u bol'nykh sakharnym diabetom.

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.
