简要总结
This is a single-center study to evaluate the safety and effectiveness of three investigational devices, the Cook Custom Aortic Endograft, the Zenith t-Branch Endovascular Graft, and the Surgeon-Modified Endografts in the treatment of Juxtarenal, Suprarenal, Thoracoabdominal, and Aortic Arch pathologies involving the at least one brachiocephalic artery or visceral vessels.
The three investigational devices offer an endovascular approach to treat complex aortic pathologies that cannot be treated with commercially available devices. This customized, endovascular approach has the potential to decrease hospital length of stay, pulmonary complications, and in-hospital mortality.
详细描述
Described as follows: Juxtarenal, Suprarenal, Thoracoabdominal aortic pathologies involving at least one visceral artery. Aortic Arch pathologies involving the at least one brachiocephalic artery.
Once the participant has signed the approved informed consent the following tests will be done to determine final subject eligibility and which device will be used:
Juxtarenal, Suprarenal, Thoracoabdominal: Clinical Exam, Blood Tests, CT Scans (with and without contrast), Abdominal Device X-ray, and Angiography.
Aortic Arch: Clinical Exam, Neurological Exam, Blood Tests, Echocardiogram, CT Scans (with and without contrast), Chest X-ray, and Angiography.
The participants will be followed for 5 years.

- •Signs that the inferior mesenteric artery (IMA) is indispensable (i.e. angiographic visualization or a large IMA, filling of superior mesenteric artery (SMA) via collaterals, stenosis of celiac or SMA or oblique views) and the indispensable IMA is not amenable to treatment with a graft branch or fenestration.
- •Branching, duplication, aneurysm or untreatable stenosis of the celiac, SMA or renal arteries that would preclude implantation of the investigational devices.

- •Proximal neck > 44 mm or < 28 mm in diameter
- •Inadequate landing zone to allow adequate distal seal of exclusion of false lumen perfusion in dissection.
- •Untreatable branch vessel stenosis.
