title: A comparative study of the degree of arterial recanalization in kidneys of dogs following transcatheter embolization with eight different materials.
abstract: 41 dogs were subjected to percutaneous arterial embolization of branches or the main trunk of the renal artery with or without prior injury to the kidney. 8 materials were used: homologous blood clot, muscle, fat, fascia, barium sulfate, plain catgut, gelfoam and polyvinyl alcohol (Ivalon). From the angiographic investigation over a relatively long period, it was observed that complete recanalization of the embolized vessels occurred only with blood clot and gelfoam; partial recanalization, with muscle fat and plain catgut; and no recanalization at all with fat, barium sulfate and Ivalon.
