[Determination of local muscular blood flow in the hindlimbs of dogs following electrolysis of conducting vascular prostheses previously implanted in the abdominal portion of the aorta].
Peripheral blood flow in the posterior limbs in electrolysis of electroconductive vascular prosthesis preliminarily implanted into the abdominal aorta was experimentally determined on 25 mongrel dogs. Following reestablishment of the main blood flow a positive electrical potential (3--4 V) was fed on the prosthesis by means of a current conductor. Tissue blood flow was radiographically studied with xenon-133. Results of this investigation showed that during feeding the positive potential to the electroconductive prosthesis an increase of tissue blood flow occurred in the canine posterior limbs. After the cessation of the current feeding to the prosthesis the tissue blood flow occurred in the canine posterior limbs. After the cessation of the current feeding to the prosthesis the tissue blood flow decreased to the initial values. A conclusion was drawn that a positive potential from the source of direct current should be fed constantly to the electroconductive prosthesis or prolonged stable tissue blood flow increase.
