Shared decision-making and specific informed consent in patients with aortic aneurysms.

One-quarter of patients who were indicated for elective surgical repair of aortic aneurysms rejected surgery after shared decision-making, which involved presenting patients with an informed consent form followed by a clarification meeting for them and their families to analyze each item. The only factor that significantly influenced a rejection of the procedure was the size of the aneurysm; patients who rejected surgery had smaller aneurysms than those who accepted surgery. Up to 26% of patients with aortic aneurysms refused surgical repair. The proposed technique, whether open or endovascular, did not influence patients' decisions. Patients with smaller aneurysms were more likely to refuse aortic aneurysm treatment.
