[A case of gastric antral vascular ectasia (GAVE) with chronic renal failure].

A 76-year-old woman was admitted to our hospital complaining of tarry stool, general fatigue and marked anemia(Hb 5.2 g/dl). Gastric endoscopic findings showed longitudinal red stripes and diffuse erythematous spots, indicating dilated vascular vessels. They resembled the stripes of a watermelon at the gastric antrum. The marked anemia was caused by chronic blood loss from the abnormally dilated mucosal and submucosal capillary veins in the gastric antrum. She was diagnosed as having gastric antral vascular ectasia(GAVE) with chronic renal failure(CRF). The association of GAVE and CRF is considered to be rare according to previous reports in Japan. Endoscopic argon plasma coagulation therapy was performed three times. After therapy, capillary dilatation disappeared, and the marked anemia was greatly improved. Argon plasma coagulation therapy was found to be a safe and effective procedure for this disease. Although GAVE is essentially a benign gastric disease, endoscopic therapy should be the treatment of first choice for this disease.
