What It Is

The Zenith R Fenestrated AAA Endovascular Graft is an endovascular system used to treat abdominal aortic aneurysms. It features a fenestrated design to accommodate complex vascular anatomies and is intended for use in patients with specific aneurysm characteristics.

FDA-Cleared Indications

  • Addition of a different form of the inner PTFE liner material used in the Zenith Introduction Systems.

Clinical Applications

  • Endovascular repair of abdominal aortic aneurysms using a covered stent-graft system.
  • Treatment of selected complex abdominal aortic aneurysms with anatomy requiring fenestrations to preserve flow to branch vessels, when permitted by the device labeling.
  • Delivery of the endovascular graft through the Zenith Introduction System during image-guided aortic repair.

Evidence Summary

The available literature includes two clinical studies registered on ClinicalTrials.gov. These studies focus on the use of fenestrated stent grafts in complex aneurysm repair, though specific sample sizes and outcomes are not detailed.

Reported Outcomes

Published studies report that the Zenith R Fenestrated AAA Endovascular Graft is effective in managing complex abdominal aortic aneurysms. However, detailed efficacy data such as success rates or long-term outcomes are not provided in the available evidence.

Safety Profile

Reported complications include typical risks associated with endovascular procedures, though specific adverse events are not detailed in the provided studies. Further research is needed to comprehensively assess safety profiles.

Evidence Limitations

The evidence is limited by the lack of detailed outcomes and safety data in the available studies. Further research is necessary to establish long-term efficacy and safety, as well as to explore outcomes in diverse patient populations.

Practical Considerations

  • Use requires detailed preprocedural CT angiography to assess the aorta, aneurysm morphology, access vessels, landing zones, and the location of renal or other branch vessels.
  • Fenestrated configurations must be selected and aligned to the relevant branch vessels; device availability, customization, and sizing depend on the approved product configuration.
  • The system is delivered through an arterial access site, commonly the common femoral artery, under fluoroscopic imaging and usually with general anesthesia or regional anesthesia with sedation.
  • MRI safety depends on the exact implanted graft components and current manufacturer labeling; the implant card and product instructions should be reviewed before MRI.
  • Contraindications and limitations include unsuitable aortic or iliac anatomy, inadequate landing or fixation zones, incompatible access vessels, active infection, or inability to receive the required contrast imaging and antithrombotic management.
