Ultrasound in Venous Disease


Venous DiseaseLower limb venous system consists of a superficial system – immediately under the skin and deep system – surrounded by muscles and deep willing. The disease affects the superficial venous system causing varicose dilatation of the veins network. Regardless of the mechanism of production of varicose veins is important to realize that in standing, these varicose veins are filled with blood.

The volume of blood that normally exists at the superficial venous system level varies being influenced by many factors such as heat, sustained muscle activity, etc. In the case of varicose veins in the entire venous system the surface is swollen as a whole and stores an amount 3 to 8 times higher than the normal one under the same conditions. A simple mathematical calculation shows that doubling the diameter of the vein the volume increases four times. So it is stored at the varicose veins level of the lower limbs a massive amount (1-2 liters, about 25-40%) of the total blood volume of the body.

The changes in circulating blood volume to raising in standing, forces the heart to work harder, thereby increasing the frequency of attempts to compensate for this loss of blood volume, thereby it is tired more quickly. This “stuck” blood in varicose throughout the day it is stolen from all the organs: brain, heart, liver, kidney, suffering in their turn. In the evening, crossing in supine (lying) this blood stalled in the veins level throughout the day returns suddenly in circulation causing dilation of the heart. This flux/reflux of the blood causes changes at the level of the heart walls and valves.

Venous Doppler ultrasound examination is the first choice to investigate the varicose disease being painless, non-invasive, low-cost, which can be repeated as often as needed, without the risk of radiation, with her help ​​being able to reveal hidden varicose packages in the fat from the legs, most often affected by this disease are patients weighing more than ideal.

Echocardiography performed in these patients allows the detection of changes that cannot be detected by clinical examination and the electrocardiogram, allowing early diagnosis of some diseases and can begin as early as possible of an appropriate treatment, which helps the heart in her work.

Last generation devices, equipped with multiple accurately ultrasound probes allow the visualization of both superficial and deep veins as well as the hearts, blood flow direction, incompetent valves, especially the measurement, recording and storage of information for a quick and easy comparison at subsequent examinations . This allows establishing a treatment plan and appropriate follow-up for each patient.
