Duplex scanning (Doppler examinations) of arteries and veins of the head and neck, upper and lower limbs
Duplex scanning differs from ultrasound examination in that it allows the doctor not only to see arteries and veins and the surrounding tissues but also to evaluate in real time the direction of blood flow and its nature and to register blood flow velocity curve in time (spectrum).
During Doppler examinations, the proper course of blood vessels, diameter, structure and thickness of vessel walls, the state of the lumen, vascular permeability, the presence of obstacles to blood flow (atherosclerotic plaques, thrombi, tightness, tortuosities, etc.) and the influence of the detected changes on the blood supply to the examined organ are evaluated.
The study is safe and painless for patients. It requires no special training and can be done repeatedly if the follow-up is necessary.
Main complaints which require Doppler examination:
- seeing dark spots in vision,
- losses of consciousness,
- speech, vision and coordination disorders,
- coldness and numbness in hands and feet,
- paresthesia (creeping sensation),
- muscle weakness,
- limb pain on exertion (and then at rest),
- trophic ulcers.
Highly trained professionals work in AMC: professors, doctors of medical sciences, doctors of the highest category, and candidates of medical sciences. To perform the Doppler diagnostics, we use the most modern equipment that meets world quality standards.
Why should I have preventive medical examinations?
Many cardiovascular diseases may be asymptomatic for a long time. For example, atherosclerotic vascular disease can be detected at an early stage only during the examination. During its development, atherosclerosis becomes a cause of chronic ischaemic heart disease, myocardial infarction, acute and chronic cerebrovascular insufficiency, upper and lower limb ischaemia.
Dangerous diseases are also superficial vein thrombophlebitis, which is in the form of hardening, swelling, redness and tenderness along the subcutaneous veins, and chronic venous insufficiency. Its symptoms include a feeling of heaviness in the legs, increased fatigue in legs, bursting pain in gastrocnemius muscles, paraesthesia and oedema (worse in the evening), more evident subcutaneous vein pattern, the presence of tortuous varicose subcutaneous veins, skin discolourations and trophic ulcers of the lower third of the leg.
Urgent diagnostics and treatment is needed when oedema (usually one foot) and bursting pain in leg muscles suddenly occur. These symptoms may indicate an acute deep vein thrombosis. This condition requires the quickest possible ultrasound to confirm the diagnosis and perform the most appropriate treatment. Deep vein thrombosis of the lower limbs without early diagnostics and treatment can lead to life-threatening complication — thromboembolia of the pulmonary artery.
Duplex scanning of arteries of the head, neck and lower limbs is recommended for all men over 40-45 and women over 50 even in the absence of complaints.
If there are any complaints or diabetes or a genetic predisposition to atherosclerosis, the arterial examinations are necessary at any age.
