[Morphologic aspects of the results of intravascular embolization of patients with gastric hemorrhages].
The paper describes morphological alterations of 15 stomachs after endovascular embolization of the gastric artery performed for gastric hemorrhages of different etiology. Introduction of hemostatic sponge into the gastric artery results in thrombosis of its lumen followed by organization and recanalization of the thrombus. Elements of the hemostatic sponge do not resolve 1 1/2 months after introduction but do not prevent thrombus formation. Complications of embolization include the development of acute ulcers and necrotic foci in the gastric wall the extent of which depends on the development of network of intraorgan anastomoses. Complications of embolization may be prevented depending on the rate of its performance and previous alterations of the arterial walls. Epithelization of chronic gastric ulcers after embolization of the gastric artery proceeds rather slowly.
