Evaluation of Graft Material in Coronary Artery Bypass Grafting (CABG)
A study testing Coronary artery bypass grafting in people with Angina Pectoris, run by Region Örebro County at 1 site in Sweden.
Trial summary
The aim of the study is to evaluate the patency in different kinds of vessels used as graft material in coronary artery bypass grafting. The hypothesis is that vein grafts harvested with a pedicle of surrounding tissue have the same, or better, patency compared to radial grafts and that skeletonisation of the left… Read more about this study

About this study
Official title: Mid-term Patency of Radial Artery and No Touch Saphenous Vein as Grafts in CABG; A Randomised Controlled Trial.
The aim of the study is to evaluate the patency in different kinds of vessels used as graft material in coronary artery bypass grafting.
The hypothesis is that vein grafts harvested with a pedicle of surrounding tissue have the same, or better, patency compared to radial grafts and that skeletonisation of the left internal mammary artery does not effect the patency for this graft.
Read the detailed description
Patients undergoing coronary artery bypass grafting are included in the study.
Each patient receive a radial artery graft and a vein graft harvested with a pedicle of surrounding tissue to the right and left side of the heart respectively. The left internal mammary artery is used for the left anterior descending artery in a skeletonised or non-skeletonised fashion.
The evaluation is made with angiography up to 5 years after surgery.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The aim of the study is to evaluate the patency in different kinds of vessels used as graft material in coronary artery bypass grafting.
The hypothesis is that vein grafts harvested with a pedicle of surrounding tissue have the same, or better, patency compared to radial grafts and that skeletonisation of the left internal mammary artery does not effect the patency for this graft.
Detailed description
Patients undergoing coronary artery bypass grafting are included in the study.
Each patient receive a radial artery graft and a vein graft harvested with a pedicle of surrounding tissue to the right and left side of the heart respectively. The left internal mammary artery is used for the left anterior descending artery in a skeletonised or non-skeletonised fashion.
The evaluation is made with angiography up to 5 years after surgery.

Questions about this trial
What is this clinical trial studying?
A study testing Coronary artery bypass grafting in people with Angina Pectoris, run by Region Örebro County at 1 site in Sweden.
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 1 inclusion and 7 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: finished, as of the sponsor's last update on 8 Mar 2011. 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 Sweden. 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?
Functional grafts defined as opened or closed. (time frame: Up to 5 years after surgery.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 8 Mar 2011; AzTrials last refreshed its copy on 8 Nov 2026.
