Authors describe the pathophysiologic premises, technique and results obtained, in over two years, in N. 40 external valvuloplasties of the sapheno-femoral junction, performed with the following main indications: sapheno-femoral reflux and U.S. evidence of normal valve leaflets in the terminal valves of the long saphenous vein. Dilatation of the terminal segment of the long saphenous vein is reduced with the application of an external synthetic prosthesis and valvular function is restored. Good results have been obtained in N. 35 cases (87.5%). A careful pre- and peroperative procedure is necessary in order to avoid failures.

[Peripheral venous biopsy in the selection of autologous venous grafts].

Authors explain their experiences on the study and further clinical application of peripheral venous biopsy (dorsal food vein) as a systematic diagnose method for phlebopatic patients. Results from these experience seem to support the availability of this method to select patients candidates for an autologous venous graft in Cardiovascular Surgery. Peripheral venous biopsy, such as for the dorsal food vein, allows to individualize the possible injuries at the saphenous wall, previously its use for autologous graft; and it avoids the preliminary sample taking for biopsy. By this method, the requirement of an intraoperatory biopsy is also avoided and an eventual by-pass or substitution are better programmed.

[Malleable spatulas in surgery of primary and secondary varices of the legs].

A variant of Cigorraga's method, in order to eliminate communicant veins in lower limbs varix, is exposed. To localize and cut these communicants, two spatulas, one with rounded end and the other with semilunar and cutting end, are employed.
