We report two cases of two-stage surgery preceded by endovascular aneurysm repair for colorectal cancer with abdominal aortic aneurysm.
Patient 1: The patient was an 83-year-old man. He had refused to undergo surgery for abdominal aortic aneurysm despite recommendations by his physician. He presented with blood discharge and dizziness, and detailed examinations revealed the presence of cancer in the ascending colon with severe anemia, as well as abdominal aortic aneurysm measuring 100 mm along the short axis.
Patient 2: The patient was an 82-year-old man who presented with a chief complaint of abdominal distension. He had rectosigmoid cancer with colonic ileus, as well as abdominal aortic aneurysm measuring 54 mm along the short axis.
Considering the risk of infection with vascular grafts, we performed endovascular aneurysm repair followed by a secondary procedure. The secondary procedure for colorectal cancer was performed 7 days and 11 days after endovascular aneurysm repair for patient 1 and 2, respectively. A colonic stent was used prior to endovascular aneurysm repair in patient 2 in order to perform the subsequent procedures safely.
Given that both cases were treated safely within a short period of time, this strategy may be useful in colorectal cancer patients with abdominal aortic aneurysm.
