title: [Role of the vasa vasorum in the process of remote vascularization of the Wesolowski Weavenit arterial prosthesis (experimental research)].
abstract: Experimental research was carried out for the purpose of studying the behaviour of the vasa-vasorum in a group of animals in which, by means of a Weavenit prosthesis, the section of aorta lying between the branches of the renal arteries and the trifurcation of the terminal oartic section had been substituted. From the results of the research the Authors conclude by asserting that above all the technique they used allowed excellent visualisation of the vasa-vasorum, as shown both by the histological preparation coloured with haematoxylin-eosin and by the preparations carried out under the stereomicroscope. Furthermore, in the microscopic observations there is the indisputable presence of vessels of varying calibre which, from the neo-adventitia through the meshes of the prosthesis, are carried to the level of the neointima, confirming that the vasa-vasorum constitute the most important reactive phenomenon for purposes of vascularisation of the prosthesis.
