A Cost-Effectiveness Model Comparing Endovascular Repair to Open Surgical Repair of Abdominal Aortic Aneurysms in Canada

OBJECTIVES: The primary risk of abdominal aortic aneurysms (AAAs) is rupture, which is associated with a high mortality rate. Elective surgical options for AAA include open repair (OR) and endovascular aneurysm repair (EVAR). EVAR is less invasive than OR, and therefore may have less surgical risk than OR. However, the graft used for EVAR is much more expensive then the graft used for OR. METHODS: A decision model with a 10-year time horizon …
