[Ultrasonography of the popliteal fossa. Survey of a small saphenous arteriole before sclerotherapy].

Routine investigation by ultrasonography with pulsed Doppler was carried out in 125 patients, candidates for sclerosing injections of the short saphenous. Study of the contents of the popliteal fossa, of the short saphenous, of the position of its junction in relation to the joint line of the knee, as well as detection of a possible satellite arteriole of the short saphenous was undertaken from a hemodynamic and topographic standpoint. A small calibre satellite arteriole of the short saphenous was a virtually constant finding, situated deep to the junction of the short saphenous, parallel to the latter at its origin, and interposed between the popliteal and short saphenous veins.
