We herein present the case of a 66-year-old man with both gastric cancer and an infrarenal abdominal aneurysm. The patient's medical history included bladder cancer, chronic renal failure, and ischemic heart disease. We performed a simultaneous endovascular aneurysm repair (EVAR) and total gastrectomy. Following the procedure, the patient remained in the intensive care unit for 3 days. Oral feeding was resumed on postoperative day 7, and the patient was discharged from the hospital on postoperative day 13 with no complications. Despite the patient's medical problems and higher operative risk, he tolerated simultaneous EVAR and total gastrectomy, and had a good outcome after undergoing these simultaneous procedures.
