Long-term durability of open abdominal aortic aneurysm repair

Distribution of additional aneurysmal arterial segments identified by surveillance imaging in 68 of 152 patients. Visceral and thoracic refer to the corresponding segments of the aorta.

Kaplan-Meier estimate for patients' freedom from graft-related interventions after open vs endovascular (EVAR) repair of abdominal aortic aneurysms (P value determined by Mantel-Cox log-rank univariate analysis). EVAR data are taken from Brewster et al.¹⁰

Kaplan-Meier estimate for survival of patients undergoing open repair of abdominal aortic aneurysms vs endovascular repair (EVAR; P value determined by Mantel-Cox log-rank univariate analysis). EVAR data are from Brewster et al.¹⁰

Kaplan-Meier estimate for survival of patients undergoing open repair of abdominal aortic aneurysms as stratified by age (P value determined by Mantel-Cox log-rank univariate analysis).
