A Simple Technique for the Study of Vascular Pattern

Abstract

MANY methods have been evolved for the purpose of demonstrating the microscopical vascular arrangements in tissues, difficulty having been encountered in selecting the ideal injection medium. The excellence of the results obtained by Trueta, Barclay, Daniel, Franklin and Prichard¹ in their investigations of the intra-renal circulation has brought into prominence the use of radio-opaque materials. It is evident from Barclay's account² of the methods that the injection procedure is without difficulty and results in good filling of vessels with a stable, homogeneous mass, but that the radiological and photographic aspects are more complex.
