Multicenter, single-arm retrospective and prospective registry is being conducted to confirm the clinical performance and safety of GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis when used as a Bridging Stent with Branched and Fenestrated Endografts in the Treatment of Aortic Aneurysms Involving the Renal-Mesenteric Arteries.

Up to 15 sites in Europe will be required to enroll a minimum of 220 patients that have had treatment with GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis when used as a Bridging Stent with Branched and Fenestrated Endografts in the Treatment of Aortic Aneurysms Involving the Renal-Mesenteric Arteries.

The registry procedures consist of two phases, retrospective phase and prospective phase.

The retrospective phase consists only of the collection of retrospective data (baseline, treatment and FU data) from the source documents available at the site from the time of the treatment until the enrollment date (ICF signature).

The prospective phase consists in collection of follow-up visits from the enrollment up to 5 years. The FU data collected prospectively can change from subject to subject depending on the index procedure date. Diagnostic imaging, treatment interventions, and follow up will be determined by physicians based on clinical practice standards.

Inclusion Criteria:

1. Patients treated with the GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis as a Bridging Stent in conjunction with a branched/fenestrated stent graft to allow endovascular aneurysm repair from 31 December 2021 until 01 January 2017
2. Age ≥18 years at the time of implant
3. Provision of informed consent by the patient or next of kin/legal representative (for deceased patients at registry entry, unless a waiver was granted), according to local regulations.

Exclusion Criteria:

1. Patient treated for ruptured aneurysm or who were otherwise hemodynamically unstable at the time of the procedure
2. Patient treated for acute or sub-acute dissection, <90 days from onset of symptoms
3. Patient treated using physician-modified endovascular grafts
4. Patient intended to be treated with chimney, periscope, octopus, sandwich technique per the pre-treatment case plan
5. At the time of treatment, patient had known coagulation disorders including hypercoagulability that were not amenable to treatment
6. Patient was pregnant at the time of treatment.
7. Participation in another drug or device investigational study within one year of device implant, that can confound the registry endpoints.
8. Patient had known or suspected systemic infection (including treatment for mycotic aneurysm) at the time of implant.

The registry has been designed with broad eligibility criteria to capture real-world data about GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis used as a Bridging Stent in conjunction with a branched/fenestrated stent graft to allow endovascular aneurysm repair.

Patients will be identified from hospital database.
