[Preoperative cartography of varices].

Thanks to ultrasonography it is possible to obtain more precise therapeutic indications. Dynamic scintigraphy of varicose veins is the result of pulsated Doppler but almost of colour Doppler that completely modifies the understanding of phenomenons. The aim of this complete examination is to avoid either haemodynamic or anatomical tramps. If need be, pre-operative echo-marking will follow scintigraphy. To achieve scintigraphy the first imperative is to investigate the main "vanishing points" between deep and superficial systems. Then it is necessary to locate the main incontinent axis to erradicate. From this complete examination it is possible to infer a treatment adapted to every case. This new tactical approach of diagnostic and therapy is to strengthen relationship and dialogue between the angiologist practitioner and the surgeon.
