What is vascular ultrasound?
Vascular ultrasound, also referred to as Sonography, Duplex Scans or Doppler Exams involves a noninvasive procedure with sound waves of high frequency to develop images of the veins and arteries. It is used instead of the older radiology procedures which are invasive while diagnosing vascular disease. Since vascular ultrasound is a non-invasive procedure, it’s considered relatively safer and highly costeffective.
The word “vascular” denotes the circulatory system of the body which is made up of arteries, blood vessels and veins. Vascular disease indicates the detrimental changes that take place within the blood vessels with the passage of time.
Uses of vascular ultrasound
Some of the uses of vascular ultrasound are as follows:
- The identification of narrowing or total obstruction of vessels all through the body.
- The identification of blood clots in veins, also referred to as deep vein thrombosis (DVT).
- Identifying aneurysms of vessels marked by unusual ballooning.
- Evaluate the viability of vessel for being used as graft.
- Evaluate the positive outcome of procedures
Peripheral vascular disease
Peripheral vascular disease indicates the disease associated to blood vessels outside the brain and the heart. Very often, it’s the narrowing of blood vessels that is responsible in carrying blood to the arms, legs, kidneys or stomach. There are two kinds of circulation disorders. These are as follows-
- Functional peripheral disease-They are devoid of any organic cause and don’t involve disorders in the structure of blood vessels. Normally the effects are for a short duration and are associated to spasm. An example of this disease is Raynaud’s disease. It’s triggered by emotional stress, low temperatures, smoking and working with any kind of vibrating machinery.
- Organic peripheral vascular disease. These are caused by changes in structure of blood vessels like tissue damage and inflammation. An example of this disease is peripheral artery disease. It’s caused as a result of buildup of fats in arteries which hinder the normal flow of blood.
Technicians of vascular ultrasound play a crucial role in the diagnosis as well as the treatment of patients suffering from blood vessel disorders, which includes but not restricted to atherosclerosis (cholesterol buildup and plague).
