Brewster at identified factors associated with long-term complications in patients undergoing endovascular repair of an abdominal aortic aneurysm, The authors are from Massachusetts General Hospital.
Patient selection: EVAR of an abdominal aortic aneurysm
A large aortic aneurysm was defined as >= 5.5 cm in diameter.
Risk factors for late rupture of the aneurysm:
(1) female gender
(2) late-onset endoleak
(3) first generation device
Risk factors for aneurysm-related mortality:
(1) need for reintervention (any type)
(2) family history of aneurysmal disease
(3) renal insufficiency (serum creatinine >= 2.0 mg/dL)
Risk factors for reintervention:
(1) use of a first generation device
(2) late-onset endoleak
Risk factors for conversion to open repair:
(1) use of a first generation device
(2) persistent or late endoleak
(3) any previous reintervention
(4) female gender
Factors associated with mortality after the procedure:
(1) unfit for open surgery
(2) older age
(3) 2 or more major comorbidities (overlaps with unfit for open surgery)
(4) large preoperative aortic aneurysm
