About this study
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.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A study testing Endovascular Branched Stent-Graft in people with Thoracoabdominal Aortic Aneurysm and Paravisceral Abdominal Aortic Aneurysm, run by Warren J. Gasper, MD at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 5 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Warren J Gasper, MD (415 750 2115, warren.gasper@ucsf.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Successful implantation of TAAA branched stent-graft. (time frame: 1 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00483249, which also lists 31 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Mar 2026.
