A bypass graft ultrasound views and records the blood flow following a surgical graft procedure (bypassing diseased vessels with man-made material or healthy veins from your arms or legs). Ultrasound is a procedure that uses sound waves to "see" inside your body. This procedure uses sound waves to create a color map of the the blood flow to the graft area and can identify blood clots, narrowing or blockage of the vessel causing pain or limping. At the S. Mark Taper Foundation Imaging Center, we have a specialized team of physicians, nurses and technologists who are experts in ultrasound radiology.

During Your Exam
- The vascular technologist will explain your exam and answer any questions you may have.
- Your procedure will be performed with you lying on the examination table on your back with your hands at your sides or on your stomach.
- The technologist will apply warm gel to your leg(s).
- A transducer, a small, microphone-like device, will be placed over various locations on your leg(s).
- You blood pressure will be taken at both your foot and your arm.
- You will not feel any pain; however you will feel mild pressure from the transducer and blood-pressure cuff.
- Sound waves will bounce off the muscle tissue in your leg(s) and the blood moving in your arteries and graft. This creates "echoes." The echoes are reflected back to the transducer. A television monitor shows images as the transducer converts the echoes to electronic signals.
- These images may be viewed immediately or photographed for further study.
- Additionally, you may hear unusual sounds as the technologist views and records the blood flowing through the veins and arteries in your leg(s).
- Your exam will take approximately 30 minutes.
After Your Exam
- There are no post-exam instructions.
- Your study will be reviewed by a vascular surgeon and the results sent to your physician. Your physician will discuss these results with you and explain what they mean in relation to your health.
- If you have any problems related to your procedure, please call 310-423-8000.
