Bypass graft surveillance is an ultrasound of the leg where an arterial bypass has been performed.
Through a hand-held transducer and gel applied directly on your skin, ultrasound uses non-radiation sound wave technology to create an echo image of the organs and vessels in your body.
The purpose of the scan is to check the arteries around the bypass graft site to check function and ensure patency.
You will be asked to lie on your back or front with your limb bent away from your body as much as is comfortable.
The ultrasound transducer will be placed along your skin and follow the line of your arterial system before and after bypass site.
Bypass graft surveillance uses colour imaging to understand the blood flow patterns and determine if there are any impeding areas.
Bypass graft surveillance usually takes about an hour.
Bypass graft surveillance is a non-invasive procedure so you can return immediately to your usual everyday activities.
Your bypass graft surveillance results will be reviewed and the report will be sent to your referring doctor. It is best to make an appointment with them to follow up on the results.
Venous bypass grafts are artificial blood vessels that surgeons create to bypass a blocked or weakened blood vessel.
The in situ bypass graft is a surgical procedure that is performed under local anesthesia. A graft (or tube) is taken from a blood vessel and supplies blood to the heart muscle. The region where the graft is taken from is called the (internal mammary artery) IMA.
