A PMCF Study in Patients With Infrarenal Aortic Aneurysm Treated With the E-tegra Stent Graft System

Study Overview
=================
Brief Summary
-----------------
The EASY post-market clinical follow-up study is undertaken to demonstrate safety and clinical performance of the E-tegra Stent Graft System used in endovascular treatment of infrarenal aortic aneurysm.

Detailed Description
-----------------
In this study, patients will be observed who receive an E-tegra Stent Graft for the treatment of infrarenal aortic aneurysm. The E-tegra Stent Graft will be implanted at the discretion of the treating physician. Participating physicians will provide their observations collected during routine care for patients they have decided to treat with the E-tegra stent graft. Informed consent of the patients to the use of their clinical records for study purposes will be obtained before their data will be collected in the post-market clinical follow-up study. All patients will be asked to complete questionaires focussing on the health status (HS) (SF-12) and Quality of Life (QoL) (WHOQOL-BREF). The period of data collection will be approximately 60 months from the date of intervention for each patient. Source document verification will be performed on 100% of the patients; data from all visits will be reviewed and verified against existing source documents. Complete DICOM image files of the CT scans as well as other imaging files (e.g. CEUS, MRT) will be sent to a CoreLab for independent second evaluation. There is no CoreLab screening before inclusion. All adverse events defined prior to study start, will be adjudicated by the Clinical Evaluation Committee (CEC).
