One-step mini-invasive treatment of abdominal aortic-iliac aneurysm associated with colo-rectal cancer.

BACKGROUND: Endovascular aneurysm repair (EVAR) is still now a controversial technique, which remains the subject of a number of prospective randomised trials. Although questions remain regarding its long-term durability, objective evidence exists which demonstrates its reduced physiological impact compared with conventional open repair, especially for older population and for the concomitant treatment of aortic abdominal aneurysm (AAA) and abdominal neoplas, such as colo-rectal cancer (CRC). In these patients it may reduce the high perioperative mortality. PATIENTS AND METHODS: Abdominal aortic aneurysm and colo-rectal neoplasm are occasionally discovered concurrently. Simultaneous operative treatment may be in these cases an effective management strategy, alternative to a staged procedure. The medical record of three consecutive patients undergoing mini-invasive colectomy for cancer and abdominal aortic aneurysm repair were reviewed. Data collected included mode of presentation, preoperative evaluation, colo-rectal pathology and in-hospital morbidity and mortality. Long term follow-up was obtained through office records and telephone contact. RESULTS: In one patient a asymptomatic colo-rectal mass was identified in the course of CT-scan evaluation for AAA; in the other two patients AAA was discovered during CT-scan oncological evaluation for symptomatic CRC. All patients underwent successfully concomitant repair of AAA and CRC by means of EVAR procedure and mini-invasive colo-rectal resection. Pathology revealed adenocarcinomas in all three cases. Perioperative follow-up revealed minor postoperative complications. Two years follow-up showed no cases of graft infection, and no interference of vascular procedure on oncological course of the colo-rectal malignancies.
