Arterial Duplex Scan
Lower Limb Ultrasound
- Assess blood flow in the legs
- May help in diagnosis of various conditions
- Used to detect peripheral artery disease
Our Specialist Vascular Sonographer administers an arterial duplex ultrasound procedure to look inside the arteries in the legs. Using high-frequency sound waves, we can create a colour map of the leg arteries to identify and diagnose various conditions, such as:
The sonographer will record the quality of blood flow in your lower limbs to assess the extent of the narrowing of the arteries in given areas. Your results will be available right away after the scan.
As it is a non-invasive scan, there is no recovery time, and you do not have to do anything to prepare before your appointment.
Should your sonographer identify abnormalities, they may refer you for treatment or suggest lifestyle changes you can make to improve and manage your condition.
Once you are comfortable, a gel is applied to your legs, and an ultrasound probe is used to examine your arteries.
Blood pressure readings will be taken of your ankles throughout the scan; you will be able to hear the ‘swooshing’ sound of the ultrasound. These sounds alert your clinician to where your blood flow is abnormal.
There is no discomfort associated with the procedure.
Your doctor may refer you for an arterial duplex scan if they believe you could be living with problems such as:
You may also be referred for an arterial duplex ultrasound if your clinician wishes to see if a procedure or lifestyle change to restore blood flow has been successful.
The scan can take between 30 and 60 minutes to complete. The process may take a little longer if your sonographer requires you to exercise at various intervals during the scan.
