Trial Summary

This is a study to assess the safety and effectiveness of endovascular treatment of thoracoabdominal (TAAA) and paravisceral abdominal (PVAAA) aortic aneurysms. The investigational operation involves placing a stent-graft over the aortic aneurysm.

Eligibility

Inclusion Criteria

     1. Aortic aneurysms:
    - greater than or equal to 6 cm in diameter in men,
    - greater than or equal to 5.5 cm in diameter in women,
    - and/or larger than 5 cm in diameter and enlarging at a rate of more than 5
       mm/year,
    - and/or iliac aneurysms larger than 4 cm in diameter.
     2. Anticipated mortality comparable to published rates with conventional surgical
         treatment.
     3. Life expectancy more than 2 years.
     4. Ability to give informed consent.
     5. Willingness to comply with follow-up schedule.
     6. Suitable arterial anatomy for endovascular repair.
Exclusion Criteria

     1. Free rupture of the aneurysm.
     2. Pregnancy.
     3. Known allergy to Nitinol, stainless steel, or polyester.
     4. Unwillingness or inability to comply with the follow up schedule.
     5. Serious systemic or groin infection.
     6. Uncorrectable coagulopathy.

Detailed Description

A TAAA or PVAAA is an abnormal enlargement of the aorta, the main artery in the chest and
abdomen. The standard operation for TAAA of PVAAA is performed through a long incision
extending down the side of the chest and the front of the abdomen. In the standard operation,
the weak area of the aorta is replaced with a fabric sleeve (graft). The investigational
operation is done making small incisions in both groins and the right arm and placing a graft
in the aorta through tubes that are inserted through the femoral and brachial arteries, than
fastening it in position with metal springs(stents). The combination of a stent and a graft
is known as a stent-graft. Compared with standard operation, the potential advantages of
endovascular TAAA/PVAAA repair include less pain, less disturbance of intestinal function, a
lower risk of pulmonary or cardiac complications and shorter hospital stay. The main
disadvantage of endovascular TAAA/PVAAA is an unknown success rate.

Important

Final eligibility is determined by the health professionals conducting the trial and the protocol approved by the Committee on Human Resources (CHR) at the University of California, San Francisco (UCSF). The Patient Consent Form for this trial is available upon request. For more information about this trial, please see the full posting at ClinicalTrials.gov.
