RESUMEN
We present the case of a 78-year-old woman who had unresectable advanced gastric cancer that had invaded the pancreas. Her hemoglobin level dropped to 7.0 g/dL during third-line chemotherapy. An upper gastrointestinal endoscopy showed a clot in the stomach, but the bleeding point could not be identified. She received a blood transfusion, but on the third day, she experienced a hemorrhagic shock. We conducted transcatheter arterial embolization(TAE)and subsequently performed embolization of the right gastroepiploic artery and the descending branch of the left gastric artery with an absorbable gelatin sponge. Following TAE, her hemoglobin level stabilized, and she was discharged from the hospital on the ninth day. We resumed chemotherapy, but she died 6.5 months after TAE due to the progression of gastric cancer. Based on this case, we suggest that TAE may be an effective treatment method for bleeding from unresectable advanced gastric cancer.
