Clinical Trial Summary

The INNER-B-APAC post-market clinical follow-up study is undertaken to demonstrate the safety and clinical performance of the E-nside TAAA Multibranch Stent Graft System used in endovascular treatment of patients with thoracoabdominal aortic aneurysms.

Description:

In this study, patients will be observed who are planned to be treated an E-nside TAAA Multibranch Stent Graft System for endovascular repair of a degenerative, atherosclerotic thoracoabdominal aortic aneurysm. The E-nside TAAA Multibranch Stent Graft will be implanted at the discretion of the treating physician. Participating physicians will be asked to provide their observations collected during routine care for patients he/she had decided to treat with the E-nside TAAA Multibranch Stent Graft System. Informed consent of the patients to allow the use of their clinical records for the purpose of this observational study will be obtained before data are being collected. Patient data will be documented in an eCRF at the following time points: Pre-operative planning, intervention(s), discharge(s) from hospital, 30 days, 3-6 and 12 months follow-up. The period of data collection will be approximately 12 months (depending on the time point of the 12 months FU visit) from the index procedure for each patient. A 100% source data verification will be performed regarding patient information and consent, criteria of patients to be documented, pre-operative planning, intervention(s), treatment results, adverse events, death, and reintervention. Complete DICOM image files of the CT scans will be sent to a CoreLab for independent second evaluation.
