Abstract

Twenty-eight mongrels were subjected to splenic artery implantation into the left kidney for a period of time varying from 7 days to 32 weeks. In 25 of the kidneys a renal artery stenosis was created. Angiography ex vivo, microangiography and histological examination showed that direct implantation of the splenic artery into the renal parenchyma regularly was followed by an initial thrombus formation in the implanted artery and an early recanalization of this thrombus. Newly formed vessels could be demonstrated in the vicinity of the intrarenal portion of the artery already during the second week after implantation. By way of these newly formed vessels three different types of communications were established between the implanted artery and the original intrarenal arteries.
