The vascular terminal network device in the anterior stomach wall.

The microcirculatory bed of the anterior stomach wall has been studied in man, dog, rabbit, guinea pig and rat, starting from the fact that in the modern gastro-duodenal surgery the various sectors of this stomach part have a special importance. The stomach microvascular network has been rendered manifest by microcorrosion preparations and by intravascular injections with coloured tracers (China Ink-gelatin, silver nitrate, methylene blue). Examinations under biocular magnifying glass and microscope of the histological slides, as well as of the block-transparentized ones in tetraline, have facilitated the microvascular morphometry as well as the calculation of some hemodynamic indices of blood flow evaluation in a limited territory of the anterior stomach wall. The obtained data can be of use when evaluating the microcirculation of the stomach parietal territories in selective vagotomies, anastomoses, plasties, resections and other operations of the stomach.
