Duplex ultrasound is the better decision for evaluation of reflux while in the lower extremities. It is affordable, noninvasive, and usually satisfactory towards the patient. It offers strong creation, localization and quantitation of venous reflux having a surprisingly high sensitivity (95%) and uniqueness (100%). Angioscopic remark of incompetent vein valves in chronic venous has confirmed duplex ultrasound results insufficiency. Yamaki has demonstrated that high-peak reflux velocities (“>>30 cm/s), reflux duration higher than 3 s and an enlarged valve annulus measured by duplex ultrasonography at the saphenofemoral junction are all closely linked to angioscopically deformed and incompetent terminal valves (kinds III and IV of Hoshino).
Sclerotherapy really started prior to ultrasound imaging’s progress. By detecting crepitus phlebologists of the 1950s produced means of making sclerosants and observed the circulation of healing foam. Nevertheless, all credit for your origin of foam sclerotherapy, as we learn it today, would go to Juan Cabrera of Granada, Spain. It was he who mixed the production of great foam under ultrasound guidance with administration of the broker. The analysis should start out with proof of the medical history. A household and particular venous record are of great significance. Within the particular heritage, the reasons for the cure ought to be confirmed. The patient’s view of the targets of the process should.
