[The autovenous by-pass by distal arterial occlusion of lower limbs in patients with diabetes mellitus].

Results of the autovenous by-pass in situ by distal combined arterial occlusion of femoral-popliteal and ankle arterial segments were analyzed. The main group consisted of 43 patients with diabetes mellitus and lower limbs ischemia grade IV in 81,4%. The comparison group consisted of 77 patients without diabetes and critical lower limbs ischemia in 84,4%.

[Formation of vertebral-subclavian steal syndrome in abnormal origin of the left vertebral artery from the aortic ark].

Presented herein is a clinical case report concerning the formation of vertebral-subclavian steal syndrome combined with occlusion of the left subclavian artery and an abnormal origin of the left vertebral artery from the aortic arch. Duplex scanning data and angiography findings showed that the collateral compensation of haemocirculation in the upper extremity took place through the subclavian-vertebral collateral net. Doppler ultrasonography signs of the latent steal syndrome were revealed in the intracranial segment of the left vertebral artery and were confirmed by the findings of the reactive hyperthermia test.

[Assessment of therapeutic efficacy in thromboses of the inferior vena cava by means of colour duplex scanning].

A total of two hundred and twenty-eight 18-to-83-year-old patients diagnosed with thrombotic occlusion of the lower-limb deep veins were examined in order to evaluate the possibilities of colour duplex angioscanning as a method aimed at monitoring both the course of and efficacy of treatment for acute venous thrombosis, as well as at preventing thromboembolic complications. Studied were the localization, incidence rate, and complications of the course of various types of venous thrombosis. It was demonstrated that an uncomplicated course the disease was observed in more than 80% of cases.

Ultrasound criteria for embologenicity of venous thrombosis.

Altogether 136 patients aged 17 to 79 years with a diagnosis of acute and subacute thrombosis of lower limb deep veins were examined by duplex scanning in order to derive the ultrasound criteria for embologenicity of inferior vena cava thrombosis. The authors evaluated thrombosis standing (from the emergence of the first clinical signs to its diagnosis), the length and site of the floating portion, the area of the transverse section of the thrombus, the character of the external contour, and the degree of thrombotic mass mobility. It has been established that: along with the generally accepted criteria for floating thrombi there is a number of the echographic characteristics which exert a significant effect on the probability of embolic complications; the degree of thrombotic mass mobility has a material effect on the incidence of thromboembolic complications and may be classified as insignificant, moderate and pronounced while embolic complications are largely present when the mobility of thrombotic masses is moderate or pronounced; the incidence of thromboembolic complications is significantly higher in the presence of a floating thrombus having uneven hypo- and isoechogenic contour and heterogeneous structure.
