Decision making in AAA repair in 2012: open or endo?

Area of Science:

• Vascular Surgery
• Medical Decision Making
• Health Services Research

Background:

• Evidence for elective endovascular abdominal aortic aneurysm (AAA) repair is extensive, posing challenges for clinicians and patients.
• Comparative data on short- and long-term outcomes between endovascular repair (EVAR) and open repair (OR) is crucial for informed decision-making.

Purpose of the Study:

• To present recent, relevant data comparing EVAR and OR for AAA repair in a concise format.
• To guide objective patient counseling by synthesizing evidence on survival, reinterventions, complications, and quality of life.

Main Methods:

• Analysis of data from four randomized trials on elective AAA repair.
• Inclusion of post-hoc analyses focusing on causes of death, reinterventions, renal function, complication prediction, and quality of life.

Main Results:

• EVAR demonstrates a three-fold reduction in operative mortality compared to OR.
• Survival curves converge over time, diminishing the long-term survival advantage of EVAR.
• Higher risks of reintervention and complications are associated with EVAR, particularly in older patients with larger aneurysms.
• Quality of life benefits from EVAR are short-lived and may be surpassed by OR in some domains.

Conclusions:

• Objective patient counseling requires presenting the trade-offs between EVAR's reduced operative mortality and increased reintervention/complication risks.
• EVAR may be more beneficial for younger, lower-risk patients, while OR might be preferable for older patients with larger aneurysms.
• Understanding long-term outcomes and quality of life differences is essential for physicians and healthcare managers, even if not directly discussed with all patients.
