Evaluation of Branch Endografts in the Treatment of Aortic Aneurysms

Zenith t-Branch Study Cohort: The purpose of this study is to collect information on the Cook Zenith t-Branch endovascular stent-graft system and the Terumo Arch Branch for the treatment of aortic aneurysms. Terumo Arch Branch Study Cohort: The purpose of this additional study arm to the current IDE clinical trial is to collect a priori information on the Terumo Arch Branch Endograft for the treatment of proximal thoracic aortic pathologies that cannot be treated with conventional thoracic endografts.

Zenith t-Branch Eligibility Criteria: Inclusion Criteria The patient must have one of the following: 1. Degenerative, atherosclerotic thoracoabdominal, suprarenal and juxtarenal aortic aneurysms (fusiform or saccular):≥55mm in diameter in a male or ≥50mm in diameter in a female, or 2. Thoracoabdominal aortic aneurysm with a history of growth ≥0.5 cm per year, or 3. Penetrating ulcers: ≥20mm in depth or 4. Chronic type B aortic dissections: ≥50mm total aortic diameter or 5. Symptomatic pathology (aneurysm, ulcer or chronic dissection) of any size. Additional criteria for LP material • Iliofemoral access vessels \
