Non-invasive Vascular Lab
The non-invasive vascular lab at Vascular and Vein
Specialists is an integral part of our vascular surgical practice. Our lab is accredited by The Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL) and all of our technologists are certified Registered Vascular Technologists (RVT). Our office based non-invasive vascular lab was established in 1980 and was the first in Greensboro.
The vascular lab performs non-invasive ultrasound duplex of the carotid, renal, mesenteric, aortic and lower extremity arteries.
We also perform ultrasound duplex for venous disorders such as varicose and spider veins and deep vein thrombosis (DVT) and vein mapping for planning of hemodialysis arterial venous fistula placement.
We also perform studies for Peripheral Arterial Disease (PAD) such as Ankle Brachial Indices (ABI) and all of the procedures performed in our lab are without radiation and painless.

Carotid Artery Duplex
Non-invasive ultrasound is used to determine amount of stenosis (blockage) in carotid arteries. We also perform duplex to recheck patients who have had carotid procedures to make sure they are not developing recurrent plaque build-up.
Renal and Mesenteric Artery Duplex
High blood pressure can be caused by narrowing of the arteries to the kidneys. Renal Duplex can determine if the renal arteries are narrowed and determine if underlying damage has already occurred to the kidney from long-standing high blood pressure. Patients can also develop blockages of the abdominal arteries. Duplex can check for narrowing of these arteries as well.
Aortic Duplex
Duplex can determine if you have an aortic aneurysm. We can also do serial exams over time to determine if your aneurysm is growing and also check for endoleak status post AAA repair.
Extremity Artery Duplex
Duplex ultrasound can show narrowings in the leg or arm arteries. We can also check for renarrowing after bypass surgery or stenting.
Ankle Brachial Index
By measuring the blood pressure in the patient's arm and comparing this to the leg. We can determine if the amount of blood flow to the leg is adequate or decreased.
