Abstract

|
|
A study was made for investigation of fine vascular alterations in gastric ulcer by microangiographic technique.
Specimens were removed by routine surgical technique of gastric ulcer, and ir_dia ink wts infused in 150 cm H,O pressure following irrigation with procaine heparin saline dextran solution. Frozen section was made in 100-200P thickness after fixation of the specimens with 10% formalin for one week, then observed under microscope.
The results obtained were as follows:
1. The microangiographic findings of normal gartric mucosa represented a characteristic pattern of distribution which is perpendicular to mucosal surface and showed a vascular network with abundant anastomoses in its base.
2. It was also demonstrated in normal gastric wall that the vessels in submucosa are virtually parallel with the mucosal surface and form the so-called submucosal vascular network, in muscularis propria, however, the large piercing vessels run somewhat perpendicularly without significant anastomoses, and in subserosa, the arterioles branched from main arteries are distributed longitudinally or crossly with emitting their fine branches.
3. In the cases of acute mucosal erosion, partial loss of terminal portion of the mucosal vessels was recognized and there was no significant abnormalities in other layers.
4. In chronic gastric ulcer, there was noted that the fine vessels are low in height and sparsely distri buted to the ulcer surface with demonstrating fibrotic changes and tissue edema in deep layer.
