Blood flow in the mucosa of fundus and antrum behave quite contrary after TV: Whereas mucosal flow of the fundus is reduced, mucosal flow of the antrum increases significantly. But 3 weeks after TV flow values of the fundus are in the range of the initial blood flow and are decreased significantly in the antrum. The early diminution of the blood flow in the mucosa of the fundus can be partly responsible for the favourable effect of TV, which is observed on erosive bleedings in this region.
