[Viability of the kidney following autovenoplasty of its artery].
A segment of one of the renal arteries of the dog was substituted for a piece of the femoral vein of the same dog. Along the site of vascular anastomoses the kidney was excluded from general blood circulation. The results of the vessel plastics were not always favourable. Inspite of the independence of anastomoses in the course of operation, the lumen of the substituted piece of the renal artery underwent deformity in a number of experiments, the circulation of the kidney was disturbed, the parenchyma of the organ was injured, a part of renal bodies and tubules were atrophied, intraorganic vessels, especially glomeruli were reconstructed. The alterations were of focal character. In general the structure of the kidney was preserved. In most experiments the substitution of the renal artery for the own vein did not cause any disorders. The wall of the transplanted vein was soon reconstructed--artealized, the renal parenchyma kept normal structure. The success of vascular plastics and the full value of blood circulation was controlled by removing the twin organ. Animals with one kidney lived practically unlimited time without obvious disorders, the content of nitrogen in the blood was normal, no alterations were found in intraorganic vessels and the renal parenchyma.
