The London Clinic has a team of very highly experienced Clinical Vascular Scientists who have provided an extensive fully specialised vascular ultrasound service to The London Clinic for over 20 years.

The team assesses outpatients and inpatients for a wide range of peripheral vascular diseases using non-invasive ultrasound machines. We provide detailed reports with stored images, and will liaise as appropriate with referring doctors.

The service runs a clinic every weekday as well as an on call service for urgent scans that require same day assessment evenings and weekends.

What is a Vascular Ultrasound scan?

A vascular scan is a non-invasive, painless scan using high frequency sound waves to assess the blood flow in the arteries and veins throughout the body. This is done by placing a probe on the skin with some ultrasound gel and then passing the probe across the skin with light pressure.

You will lie on a bed or stand on a step depending on the test you are having. You may be asked to remain fairly still for the scan. Once the scan is finished you can leave straight away.

Types of Vascular Ultrasound scan

Carotid Duplex Scan: It makes use of two types of ultrasound – B Mode and Doppler – to scan neck arteries that feed the brain. It takes up to 30 minutes. It is performed to check for symptoms including transient ischemic attacks ('mini strokes'), stroke, or screening for very early disease of narrowing or blockage of the vessels.

Lower Limb Arterial Duplex Scan: This is an ultrasound of the leg arteries from your abdomen to your ankle. It takes up to one hour. This is for intermittent claudication - pain in the legs when walking, acute ischemic disease (sudden blockages of the arteries), and aneurysms (short enlargement of the artery).

Lower Limb Venous Duplex Scan: This is an ultrasound scan of the leg veins and takes up to 45 minutes and is for deep vein thrombosis - acute and chronic, varicose veins.

Aortic Duplex Scan: A scan of the main abdominal arteries. It takes up to 30 minutes. This is for abdominal aortic aneurysms - short enlargement of the main artery in the abdomen and endo-vascular stent follow-ups - graft used to treat the enlargement.

Upper Limb Venous Duplex Scan: An ultrasound scan to check for thrombosis which is an acute blockage of the arm veins or thoracic outlet syndrome (compression of the arm veins by the musculoskeletal system in the neck/shoulder region).

Upper Limb Arterial Duplex: An ultrasound scan of the arteries of the arm. The scan takes up to 45 minutes. The scan is used for detecting symptoms of Ischemia and thoracic outlet syndrome (compression of the arm veins by the musculoskeletal system in the neck/shoulder region).

Fistula assessment (pre and post dialysis): These are ultrasound scans of the arms to assess the veins for dialysis patients and to monitor any access fistula veins after they have been created for dialysis. The scans take up to 45 minutes.
