MORHOLOGICAL AND FUNCTIONAL ASPECTS OF THE APPLICATION OF FEMORAL VEINS FOR AORTOILIAC RECONSTRUCTION IN EXPERIMENT

The aim of the study. To study the functional adequacy of different vascular conduits. Material and methods. The morphological and functional qualities of femoral vein in comparison with those of superficial vein and artificial prosthesis in 12 pedigreeless male dogs weighted 15,3 ± 3,7 kg have been studied. All the dogs underwent ilio-femoral bypass with combined conduit, sewn from the fragments of femoral vein, superficial vein and polytetrafluorinethylene vascular prosthesis. The specimens were obtained in the interval of 3, 6, 9 and 12 months. Mann-Whitney`s U-criterion, a non-parametric method for comparison of two independent samples was applied to compare the quantities that are not subject to Gauss` distribution. Results and discussion. The apex of morphological-functional rebuilding of veins, caused by their involvement in arterial flow, seems to appear in the interval from 3 to 6 months since the implantation. The changes of femoral vein occur earlier then those of subcutaneous vein. The dystrophic signs are less expressed in femoral vein. The morphological-functional properties of femoral vein differ from those of superficial vein. A peak of regenerative processes on the surface of the artificial vascular prosthesis falls on the term of 6 months. The later termed involutive processes prevail over the regenerative processes.
