Endovascular treatment for thoracoabdominal and paravisceral aortic aneurysms

Endovascular Exclusion of Thoracoabdominal and/or Paravisceral Abdominal Aortic Aneurysm

Not applicable Interventional University of California, San Francisco · NCT00483249

This study is testing a less invasive way to treat certain types of aortic aneurysms using a stent-graft to see if it can reduce pain and recovery time compared to traditional surgery.

What this trial studies

This study evaluates the safety and effectiveness of an endovascular approach to treat thoracoabdominal and paravisceral abdominal aortic aneurysms. The procedure involves placing a stent-graft over the aneurysm through small incisions in the groins and arm, as opposed to traditional surgery which requires a large incision. The goal is to reduce pain, minimize complications, and shorten hospital stays compared to standard surgical methods. Participants will be monitored for outcomes related to the success of the stent-graft placement and overall recovery.

Who should consider this trial

Good fit: Ideal candidates include individuals with significant aortic aneurysms who meet specific size and anatomical criteria and have a life expectancy of more than two years.

Not a fit: Patients with free ruptures of the aneurysm, pregnancy, or serious systemic infections are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this approach could offer a less invasive treatment option with fewer complications for patients with aortic aneurysms.

How similar studies have performed: Other studies have shown promising results with endovascular techniques for aortic aneurysms, indicating potential for success in this approach.
