ZEnith AlPHa for AneurYsm Repair
- Conditions
- Aneurysm
- Registration Number
- NCT03165279
- Lead Sponsor
- Philippe Cuypers
- Brief Summary
To prospectively collect 'real world' performance data on the Zenith AlphaTM Abdominal Endovascular Graft for endovascular aneurysm repair, inside and outside instructions for use. To assess clinical efficacy of the low-profile device to treat patients with abdominal aortic aneurysm (AAA), to assess the use of the new delivery and deployment system of the Zenith AlphaTM Abdominal Endovascular Graft. Primary endpoint is the proportion of subjects who experience successful treatment at 1 year post-implant; defined by technical success and clinical success.
- Detailed Description
The ZEPHYR registry has two major objectives:
1. to prospectively collect 'real world' safety, durability and clinical performance data on the Zenith AlphaTM Abdominal Endovascular Graft in subjects with infrarenal abdominal aortic or aorto-iliac aneurysms.
2. To increase the clinical evidence about the safety and effectiveness of the Zenith AlphaTM Abdominal Endovascular Graft by creating a database that can be pooled and/or compared with databases available on this and other stent graft systems.
The ZEPHYR registry is a multi-center, post-market, non-randomized, single-arm prospective study. The study has no controls, as it is descriptive in nature. It will recruit approximately 450 subjects from high-volume sites across Germany and the BeNeLux. Study is open to consecutively enrolled subjects (20-50 per site) whou in the opinion of the investigator are candidates for endovascular AAA repair. The sites are recommended to schedule the subject's post-operative follow-up visits based on the current standard care in endovascular aneurysm repair (EVAR) therapy, which is generally at 1 month, 1 year and annually thereafter.

All-cause mortality at 1 month, 1 year and at 2 years All-cause mortality
Endoleak at initial procedure, 1 month, 1 year and at 2 years Any type of endoleak; tabulated by type (Ia, Ib, II or III)
Amount of secondary procedures to correct endoleaks From the day after the initial procedure up to 2 years after the initail procedure (which is the end of the follow up period for this registry) Secondary procedures to correct endoleaks
Amount of secondary procedures for occlusion and/or kinking to restore stent graft function (endovascular and open procedures) From the day after the initial procedure up to 2 years after the initail procedure which is the end of the follow up period Amount of secondary procedures for occlusion/kinking to restore stent graft function (endovascular and open surgical procedures)
Amount of secondary surgical interventions for stent graft infection From the day after the initial procedure up to 2 years after the initail procedure which is the end of the follow up period Amount of secondary surgical intervention for stent graft infection
Amount of major lower limb amputation From the day after the initial procedure up to 2 years after the initail procedure (which is the end of the follow up period for this registry) Amount of major lower limb amputation
Which kind of vascular access is used during surgical intervention at the primary procedure Vascular access can either be unilateral, bilateral, open access or percutaneus access
Access site complications during procedure up to 45 days Hematoma, false aneurysm, vessel injury, primary conversion to femoral cutdown, surgical reintervention postoperative, false aneurysm at puncture site
Amount of secondary open surgical interventions From the day after the initial procedure up to 2 years after the initail procedure (which is the end of the follow up period of this registry) Amount of secondary open surgical interventions
Major adverse events at 1 month, 1 year and at 2 years all-cause mortality, bowel ischemia, myocardial infarction, paraplegia, procedural blood loss \>1000 cc, renal failure requiring dialysis, respiratory failure, stroke
