[Anesthetic management for gastrectomy in two gastric cancer patients after coronary artery bypass grafting using right gastroepiploic artery]

Abstract

We report two cases for anesthetic management of gastrectomy for gastric cancer which took place after receiving coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA). The first patient was a 75-year-old man after CABG using the RGEA 14 years before. He was diagnosed with gastric cancer and was scheduled for total gastrectomy. Preoperative coronary angiography (CAG) showed complete occlusion of the right coronary artery (RCA), whereas RGEA was patent. Because percutaneous coronary intervention (PCI) was hard to perform on the occluded RCA, proximal gastrectomy was carried out without lymph node dissection. The surgeons judged the surgery enough for radical treatment. Surgery was accomplished without any problems. The second patient was a 76-year-old man after CABG using the RGEA 15 years before. He was diagnosed with advanced gastric cancer and was scheduled for distal gastrectomy. Preoperative CAG showed the RCA partially occluded and the RGEA remaining patent. He received the scheduled surgery after confirmation of the success of PCI, performed preoperatively for reperfusion of the occluded segments. Although the RGEA was incised during the surgery, gastrectomy was accomplished without any problems in the cardiac function.
