Trial summary

This study is a comparison of two different ways to treat blockage in the artery of the thigh. The first is an older way with incisions in the groin and just above the knee. A plastic tube is then inserted to make a bypass from the groin to the knee. The second treatment offered is through a needle hole in the groin. Read more about this study

About this study

Official title: A Prospective Randomized Comparison of Prosthetic Femoropopliteal Bypass Versus Viabahn Endoprosthesis for Treatment of Symptomatic Superficial Femoral Artery Occlusion

This study is a comparison of two different ways to treat blockage in the artery of the thigh. The first is an older way with incisions in the groin and just above the knee. A plastic tube is then inserted to make a bypass from the groin to the knee. The second treatment offered is through a needle hole in the groin. A thin plastic tube covering a metal stent is inserted into the artery and released to bypass the blockage from inside the artery. No incisions are needed. Patients are enrolled and then selected for one treatment method or another by chance. The patients will be followed for two years to see how the two different treatment methods work compared to each other.

Questions about this trial

What is this clinical trial studying?

A study testing Femoral-popliteal Bypass and Angioplasty and stent placement with Viabahn covered stent-graft(W.L. Gore & Associates, Flagstff, Arizona) of superficial femoral artery in people with Atherosclerosis and Lower Extremity Ischemia, run by Texas Vascular Associates at 1 site 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?

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: finished, as of the sponsor's last update on 9 Jun 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary artery/graft patency (time frame: 24 months). The study lists 3 primary outcomes in all. 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 NCT00693823, which also lists 3 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 9 Jun 2008.
