Investigation of Venous Disease
An expert physical examination along with obtaining a medical history are important parts of the consultation to assess the veins and the condition of the skin. This will demonstrate the extent of the varices and detect any signs of leg swelling, discolouration or ulcers. Clinical examination is useful but it is also necessary to undertake duplex ultrasound scanning to define the exact anatomy of the faulty veins.
A duplex ultrasound scan is a non invasive investigation which is the gold standard for defining the anatomy of venous disease. With colour duplex ultrasound imaging all veins and arteries can be visualised so that the direction of the blood flow can be demonstrated and measured. It will detect leaky valves and blood flowing the wrong way down any varicose veins. A report is then produced to indicate the location of all incompetent veins as well as the origin of the problems. This investigation uses the same technology as that used to perform scanning during pregnancy to assess the developing baby.
