[Experimental restoration of the renal artery. Comparative study of 3 procedures (author's transl)].
Presentation of theee procedures of experimental revascularization of the renal artery under microscopically controlled surgered (study of 19 dogs): --10 dacron velvet grafts, --6 hypogastric autografts, --3 spleno-renal autografts. Results obtained by three means of investigation: selective angiography, measurement of renal flow using radioactive xenon, microscopic study of the anastomoses and the grafts: --10 dacron 10 failures, --6 hypogastric autografts, 4 successes 2 failures, --3 spleno-renal autografts, 3 successes. Comparative study of the different experimental and clinical works on these subjects. Dacron grafts must be banned for calibers less than 4 mm in diameter. Hypogastric autografts give good congruence of the anastomoses, poses no problems with preservstion, but necessitates two sutures which spoil the results. Spleno-renal autografts, when possible, seem to be an ideal means connnection. A single suture, no nutritional problems and rapidity of execution.
