Is Evar Feasible in Challenging Aortic Neck Anatomies? A Technical Review and Ethical Discussion.

Based on the present analysis, EVAR appears to be a safe and effective procedure-and therefore recommendable-even in the presence of hostile anatomies, in patients deemed unfit for OR. However, in order to identify and pursue the patient's best interest, particular attention must be paid to the management of the patient's informed consent process, which-in addition to being an essential ethical-legal requirement to legitimize the medical act-ensures that clinical data can be integrated with the patient's personal preferences and background, beyond the therapeutic potential of the proposed procedures and what is generically stated in the guidelines.
