[Results of using the domestic vascular prosthesis "Ekoflon"]. / Rezul'taty ispol'zovaniia otechestvennykh sosudistykh protezov "Ekoflon".

The aim of the work was to study long-term results of application of a vascular transplant from modified polytetrafluoroethylene "Ekoflon". The investigation included 121 reconstructions performed during the last 6 year, 53 prostheses being implanted in the aorto-femoral position, 68--in the femoro-popliteal-tibial position. The long-term results have shown that the transplant "Ekoflon" in the position of the aorto-femoral shunt is not inferior to textile analogues and even has a number of advantages. When it is used below the inguinal fold the results of patency were worse than those with the autovenous one. But when there is no adequate autovein, under conditions of critical ischemia, prosthesis "Ekoflon" might be the material of choice for saving the lower extremity. The dynamic ultrasound duplex scanning and histological investigation of the prosthesis samples have shown an original morphogenesis of its "implantation".

[Venous occlusive plethysmography in assessment of hemodynamics in arterial thrombosis of the lower extremities]. / Primenenie venoznoi okkliuzionnoi pletizmografii v otsenke gemodinamiki pri tromboze arterii nizhnikh konechnostei.

With the use of a method of venous occlusive plethysmography changes, in regional arterial and venous hemodynamics in 75 patients with arterial thrombosis as well as in 47 after reconstructive intervention at the immediate period, and in 25--at the late period were studied. It was established that in ischemia progression, the volume blood flow rate at rest and maximum rate decreased, indicating severe impairement in reserve possibilities of blood flow, maximum venous outflow reduced, venous filling of the vessels increased. In thrombosis, rough disorders in reserve possibilities of blood flow in the aorto-iliac segment were noted. After operation, dynamics of the indices didn't depend on type of reconstructive intervention and was determined only by adequacy of blood flow restoration in the extremity.
