Types of Diagnostic Tests

What kinds of vascular tests are most common? What happens when you have one? Will it hurt? Will it mean you need surgery? Find the most commonly prescribed vascular tests detailed on these pages by clicking one of the links on the left. Be sure to ask your surgeon if you still have questions.

Carotid, Vertebral, and Subclavian Artery Doppler

This study determines accurate localization of disease in the extracranial carotid, vertebral and subclavian arteries, and classification of the extent of blockage and reduction of blood flow to the brain and upper extremities.

Upper and Lower Extremity Segmental Pressures

The purpose of this study is to identify, localize and quantify obstruction in the arterial circulation to the arms or legs.

Upper/Lower Extremity Arterial Duplex

Duplex imaging is used to determine exact location and the extent of an arterial obstruction without angiography, permitting the Physician to discuss potential interventions with the patient.

Learn More

Upper and Lower Extremity Venous Duplex

This study is to determine if a venous thrombosis is present in the superficial and/or deep veins of the extremity and to define its extent and location. Also to determine the extent of lower extremity venous valvular incompetency.

Learn More

Mesenteric Artery Duplex

To identify a hemodynamically significant stenosis of the arteries carrying blood to the intestines and correlate GI symptoms with the presence of intestinal ischemia. Also to monitor arterial blood flow after vascular reconstruction to the mesenteric arteries.

Learn More

Renal Artery Duplex

To determine the presence of an arterial flow reducing renal artery stenosis (RAS) or occlusion and to identify high resistance arterial flow within the kidney, which suggests intrinsic parenchymal disease in hypertensive patients.

Learn More

Renal Vein Duplex

To rule out renal vein thrombosis.

Learn More

Aortoiliac Duplex

To determine the diameter of a possible aneurysm, evaluate suspected arterial occlusive disease, assess the development of an iliac pseudoaneurysm after a catherization, and to assess the patency of an aortoiliac bypass graft.

Learn More

Inferior Vena Cava and Iliac Vein Duplex

To rule out the presence of thrombus within the IVC and/or iliac veins in suspected proximal deep venous thrombosis, and to evaluate the patency of the IVC in patients who have a filter.

Learn More

Arterial Bypass Graft Surveillance Duplex

To assess the patency of the bypass graft and determine the perfusion status of the distal aspect of the extremity.

Learn More

Hemodialysis Access Graft / Fistula Duplex

To monitor the graft/fistula by ultrasound, and identify potential obstruction of the lumen, inflow and outflow anastomosis sites.
