[Morphological studies of gastric arteries in patients with gastro-duodenal ulcer].

Microscopic lesions of the gastric arteries have been studied in 21 patients subjected to resection for gastroduodenal ulcer. The left gastric artery, particularly in patients with gastric ulcer, presents lesions to the intima and media and these can lead to obliteration of the lumen, classifiable as atherosclerotic disease. The seriousness of the lesions would seem to be independent of sex and age. In some cases gastric artery lesions were compared with those to the arterioles in the vicinity of the ulcer. At least as far as the gastric district is concerned, there would not appear to be any gravity correlation between large and small vessels. Some aspects of the vascular pathogenesis of gastroduodenal ulcer are discussed.
