The most common test for PVD is the ankle-brachial index (ABI), a painless exam in which ultrasound is used to measure the blood pressure in the feet and arms. A blood pressure cuff and a Doppler unit (microphone) are used to determine pressures in the leg. A Doppler device is placed on the skin over the pulse. If there are any blockages, the Doppler makes a specific sound that will be detected by the technologist. This screening procedure takes approximately 15 minutes. A physician must refer you for this procedure.
Based on the results of your ABI, as well as your symptoms and risk factors for PVD, the radiologist can decide if further tests are needed. If your screening test indicates you are at moderate or high risk for PVD, you will return to one of our centers for a Doppler Ultrasound scan. This more extensive color exam will take approximately one hour. Echoes from the sound waves will create an image on a TV-like monitor. A vascular interventional radiologist will interpret these results, along with your history, and discuss with you and your physician any further testing or treatment.
Angioplasty a balloon is inflated to open the blood vessel. Thrombolytic therapy clot-busting drugs are delivered to the site of blockages caused by blood clots. Stents a tiny metal cylinder, or stent, is inserted in the clogged vessel to act like a scaffolding and hold it open. Stent-grafts a stent covered with synthetic fabric is inserted into the blood vessels to bypass diseased arteries. Our vascular radiologists, after interpreting your Doppler Ultrasound exam, and after consulting with your physician, may determine that you are a candidate for one of the above procedures. They will be available to discuss the procedure, risks and expected results at the time of your visit.
