Whether there is any possible abdominal aortic aneurysm surgery for gastric lymphoma?

My grandmother is 89 years. A month ago doctors diagnosed her gastric lymphoma. Currently, my grandmother take antibiotics that were prescribed by oncologists. At a later time, the oncologist will decide whether to use chemotherapy treatment. At the same time I wanted to highlight that my grandmother has to have an abdominal aortic aneurysm surgery. My questions - whether the operation of the abdominal aorta may be an obstacle if she has lymphoma of the stomach and whether the abdominal aortic aneurysm surgery may be an obstacle if the oncologist decides to use chemotherapy ??????
