Arterial Disease

Carotid Duplex Study

A carotid duplex study is an ultrasound of the carotid arteries, which are found in the neck. It is done in the office by a trained sonographer (ultrasound technologist). The ultrasound uses sound waves to see if there is plaque build up in the arteries. Plaque build up can cause narrowing of the carotid arteries which may decrease blood flow to the brain. Decreased blood flow can cause symptoms such as dizziness, unexplained syncope (passing out), change in sight, or stroke.

Abdominal Aortic Aneurysm

This test is an ultrasound of the aorta, one of the large arteries in the abdomen. It is done in the office by a trained sonographer (ultrasound technologist). The ultrasound uses sound waves to see if there is an abdominal aortic aneurysm (AAA). An abdominal aortic aneurysm is an enlargement or weakening of the walls of the aorta. An abdominal aortic aneurysm does not usually cause symptoms until it becomes an emergency. As a result, this screening test may be done if you have a history of coronary artery disease (hardening or blockages of the heart arteries) or peripheral artery disease (hardening or blockages of the arteries of the legs or neck). This is also recommended as a screening for men, aged 65-75, who smoke or have previously smoked.
