title: [Renal blood flow investigations with 133xenon and the Anger scintillation camera in the hyperacute xenograft rejection of the rabbit kidney (author's transl)].
abstract: The aim of this study was to demonstrate the advantage and validity of 133Xe-washout externally monitored by the scintillation camera. Until now there were no reports on quantitative blood flow studies in Hyperacute rejection of transplanted kidneys using a scintillation camera. Within 35 minutes after e-vivo hemoperfusion of rabbit kidneys by cats we found a simultaneous progressive decrease of renal blood flow, renal cortical blood flow as well as of the intrarenal distribution of renal cortical blood flow in all cases. The hyperacute rejection of xenografts could be verified in every case histologically. Using the scintillation camera we were able to detect regional perfusion defects caused by artifical air embolism as well as by preexisting cortical infarction.
