A 69-year-old man was under maintenance dialysis due to diabetic renal failure. He had a drop in blood pressure during dialysis, developed hematemesis, and was transported to our hospital. Emergency upper gastrointestinal endoscopy revealed diffuse erosion, mucosal sloughing, and edematous mucosa in the upper body of the stomach to the posterior wall of the antrum and to the greater curvature, which were considered to be an ischemic change. His underlying diseases included diabetic renal failure, chronic arteriosclerosis obliterans, cerebral infarction, internal carotid artery stenosis, hypertension, and myocardial infarction. Blood evaluation showed only mild inflammation and no fibrinolytic hyperactivity. Contrast-enhanced computed tomography (CECT) showed no occlusion of blood vessels. It was considered that the patient had a transient ischemic change due to blood pressure drop. The patient's condition improved with conservative treatment.
