[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.
