Carotid Artery Ultrasound
Ultrasound evaluation of the carotid arteries that screens for buildup of fatty plaque — one of the leading causes of strokes. Carotid arteries are the main blood vessels to the brain. They can develop a buildup of plaque caused by atherosclerosis, or hardening of the arteries. When the buildup becomes very severe, it can cause a stroke. A stroke occurs when part of the brain is damaged by these vascular problems; in fact, 80 percent of strokes are “ischemic strokes” where part of the circulation to the brain is cut off, usually due to blockages in the carotid arteries. The process is similar to the buildup of plaque in arteries in the heart that causes heart attacks. Strokes are the third leading cause of death in the United States according to the National Center for Health Statistics.
Peripheral Arterial Disease Testing
This test uses ultrasound and blood pressure measurements to check for peripheral arterial disease (plaque build-up) in the lower extremities. If you get leg cramps when you walk, it may be a sign of PAD. Learn more about keeping your legs healthy. Peripheral arterial disease (PAD) occurs when atherosclerosis, or hardening of the arteries, causes a buildup of plaque in the blood vessels that carry oxygen and nutrients to all the tissues of the body. As these plaques worsen, they reduce essential blood flow to the limbs and can even cause complete blockages of the arteries. Early on, PAD may only cause difficulty walking, but in its most severe forms, it can cause painful foot ulcers, infections, and even gangrene, which could require amputation. People with PAD are three times more likely to die of heart attacks or strokes than those without PAD.
Abdominal Aortic Aneurysm
The abdominal aorta serves the entire lower half of the body.
Abdominal Aortic Aneurysm (AAA) is an enlargement or “bulge” that develops in a weakened area within the largest artery in the abdomen. The pressure generated by each heartbeat pushes against the weakened aortic wall, causing the aneurysm to enlarge. If the AAA remains undetected, the aortic wall continues to weaken, and the aneurysm continues to grow. Eventually, the aneurysm becomes so large, and its wall so weak, that rupture occurs. When this happens there is massive internal bleeding, a situation that is usually fatal. The only way to break this cycle is to find the AAA before it ruptures. Nearly 200,000 people in the U.S. each year are diagnosed with an AAA, which can be deadly without treatment
