Reporting Groups

	Description
TriVascular Stent Graft	This arm is for patients that receive the TriVascular Stent-Graft System. The TriVascular Stent Graft Systems was designed to treat patients with Abdominal Aortic Aneurysms(AAA). The stent-graft was designed to provide an alternate intraluminal blood conduit and isolate the aneurysm from the blood flow.

Hide Outcome Measure 2

Measure Type	Primary
Measure Title	Number of Participants Without a Type I, III, and/or IV Endoleak at 1 Month Follow-up Identified by Computed Tomography (CT).
Measure Description	A Type I endoleak is a persistent perigraft channel of blood flow that develops due to inadequate or ineffective seal at the graft ends (attachment zones). A Type III endoleak occurs in the midgraft region due to leakage through a defect in the graft fabric or between the segments of a multisegmental graft. A Type IV endoleak is seen on completion of angiography or subsequent contrast studies as any blush of contrast that is presumed to emanate from blood diffusion across the porous graft fabric or through small holes in the graft cause by sutures or stent struts.
Time Frame	1 month
Safety Issue	Yes

Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
