Small vessels study using a radiopaque dye

Abstract

The purpose of our research consists of studying a new dye which, besides allowing the macroscopic study of small vessels <FONT FACE=Symbol>¾</FONT> following the pioneer research of Salmon(3) <FONT FACE=Symbol>¾</FONT>, permits the radiographic study due to its radiopacity. To do so, ten rats were utilized and their abdominal aorta was catheterized for the injection of the dye towards the periphery, being the flow of the dye observed along the left femoral artery (the right one was cauterized for occlusion). The results of this injection revealed that the dye penetrates well in extremely small vessels and allows dissection without extravasations. Thus, we believe that this dye has the necessary requirements for the study of details of the vascular anatomy.
