Morphometric investigations of dog kidney infarcts after embolization of the renal artery with Spongostan.

A macroscopic morphometric method for evaluating the volume of infarcts in the kidneys of dogs 24 hours, 7, 14, and 24 days after renal artery embolization by means of Spongostan is described. The whole kidney was not infarcted, the volume of the infarcts being 60.15-81.87% (mean 71.1%) of the volume of the embolized kidney. In order to evaluate the distant morphological changes in the parts of the embolized kidney not involved in the infarcts, it would be necessary to carry out microscopic examinations and to have a longer observation period.
