Endovascular Aneurysm Repair versus Open Repair in Patients with Abdominal Aortic Aneurysm
This chapter provides a summary of the landmark EVAR Trial 1, which compared endovascular repair of abdominal aortic aneurysms (AAA) with open repair in patients judged to be fit for both open and endovascular repair. Although endovascular AAA (EVAR) repair was associated with lower perioperative complications and mortality than open surgical repair, after 4 years of follow-up the outcomes of the two approaches were similar. Follow-up at 15 years found EVAR had inferior late survival, necessitating lifelong surveillance of EVAR and reintervention if necessary. The chapter describes the basics of the study, including funding, year study began, year study was published, study location, who was studied, who was excluded, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, gives a summary and discusses implications, and concludes with a relevant clinical case.
