Priority of resection in concomitant abdominal aortic aneurysm (AAA) and colorectal cancer (CRC): review of the literature and experience of our clinic

Abstract

The concomitant occurrence of abdominal aortic aneurysm (AAA) and colorectal cancer (CRC), although rare, always represents a therapeutic dilemma. The incidence of coexistence ranges between 0.49 and 2.1%. Both lesions should be treated to achieve best life expectancy. But the main controversy revolves around whether to treat them simultaneously or as staged procedures. In our institution, we treated seven cases of concomitant AAA and CRC. In five of them, synchronous conventional resection was preferred. In the latest two, which we present, endovascular aortic repair was chosen. No graft infection was documented.
