Anatomical Feasibility of Multibranched Off-the-shelf Endografts for Thoracoabdominal and Para-renal Aortic Aneurysms (TAMBE Study)

To evaluate the theoretical anatomical feasibility of multibranched off-the-shelf endografts in patients with thoracoabdominal and para-renal aortic aneurysms based on retrospective review of pre-operative imaging studies of the patients treated for this pathology in the San Raffaele Hospital's Vascular Surgery Unit in the past ten years.

Materials and methods:

The investigators review retrospectively the pre-operative contrast-enhanced computed tomography scans (CTA), stored in the hospital PACS, of the 562 patients treated at the San Raffaele Hospital's Vascular Surgery Unit, between January 2007 and January 2017 by means of open aortic aneurysm repair. All patients involved in the study have already signed informed consent for data collection and analysis at hospital admission.

Inclusion criteria:

• patient who underwent treatment of thoracoabdominal or para-renal aortic aneurysm at San Raffaele Hospital in between January 2007 and January 2017.
