Of the 229 patients with ulcerous bleeding operated on, 27 (11.8%) died. In 19 of them, the death was caused by hemorrhagic syndrome with severe disorders in rheologic blood properties. Considerable decrease in capability of erythrocytes for deformation is, possibly, a pathogenetic link of the posthemorrhagic syndrome development.
