Written informed consent will be obtained from the patient or patient's authorized representative prior to enrolment in the Registry. In case of emergent surgery, informed consent will be collected from the patient's family (or legal representative) before surgery, as well as from the patient after surgery (if unable to give it before intervention). This consent will be waived in case of death or severe neurological damage precluding adequate postoperative patient informed consent. The study will be conducted in accordance with the provisions of the Declaration of Helsinki.
