[Measurement of venous pressure by Doppler sonography: usefulness and limitations in saphenectomy].

: After a short mention on the many last methods for venous pressure measurement, the Authors presents a relatively new method of this measurement with the Doppler ultrasonography. They point out its utility with regard to safenectomy by a study on 42 patients whose, at the present, only 10 preliminary results are available. This results allow to verify the opportunity of to value preoperatory and precisely the pressure drop obtainable with the safenectomy.
