Our understanding of venous hemodynamics (the study of blood flow) depends on tremendous improvements in ultrasound technology.

The best treatment for varicose veins can be achieved only by performing an ultrasound scan of the veins. Veins visible on the surface often have deeper sources underneath. Varicose vein disease can be very complex and each patient is unique. Therefore, every patient receives a painless ultrasound examination to pinpoint exact problem areas thus allowing for accurate diagnosis and mapping of leg veins so that a precise and personally adapted treatment of veins can be offered and provided.


Duplex Ultrasound scanner:

this non invasive examination combines Echography and Duplex measurements. Echography permits visualization of the vein features, i.e. position, connections. Duplex measurements use sound to obtain information about the direction and type of blood flow. This examination allows the physician to create a precise map of the patient's venous anatomy and blood flow and, therefore, determine how to correct it.

chiva diagnosisMapping with color-flow duplex ultrasound scanning is the most sensitive and non invasive examination, which enables to characterize the normality of deep venous system, the sites of reflux from deep to superficial veins and perforating veins, as well as the anatomical distribution of varicose alterations within the superficial system.

The complex variations of varicose vein anatomy and functional pathology in the lower limb are identified by a duplex hemodynamic cartography .

Colour duplex scanning has revolutionised the investigation of the lower limb venous system because it allows instant visualisation of blood flow and its direction.

Colour duplex scanning of saphenopopliteal junction. The calf muscles are manually compressed producing upward flow in the vein (top), which appears as a blue colour for flow towards the heart (panel A). Sudden release of the distal compression causes reflux, seen as a red colour indicating flow away from the heart (panel B)

C.H.I.V.A is a Conservative, vein preserving treatment based on duplex ultrasound examination.

chiva diagnosisWith C.H.I.V.A. we are now capable of treating patients in an almost non traumatic manner with an extremely selective surgical procedure that preserves the saphenous trunks by relieving them of hemodynamic overload.

C.H.I.V.A depends strongly on an extensive and sophisticated duplex examination by an experienced investigator.

Interpretation of venous hemodynamics using ultrasound signals is a major achievement which allows pre-operative mapping. This means that the surgical plan will vary from case to case and that the treatment is personalized and not standardized.
