[Is there still a place for the correction of chronic venous insufficiency of the lower limbs by valvuloplasty].
OBJECTIVE
Various surgical procedures, extravenous (VPE) AND intravenous (VPI) valvuloplasties were described for the treatment of superficial (IVCS) and deep (IVCP) chronic venous insufficiency.


METHODS
In 18 years: 153 VPE in limbs affected with IVCS. 9 VPE, 26 VPI (10 typical, 8 atypical, 8 autologous) and 38 other procedures in 74 limbs with IVCP selected and controlled by US (hemodynamic improvement or normalization = MNE) and X-ray (5 VPI).


RESULTS
IVCS: 153 VPE=8,2% of the general casuistry. ;: MNE) 90,2% ( mean follow-up. 5 y,4 m.); stable at 10 y 68%; best results in IVCS <20 y. (Chi-sq.P=0.05). IVCP: VPE=12,3% and VPI=35,6% of the interventions; 9 VPE: MNE 88,8%; 26 VPI: MNE 81,4%; hemodynamic normalization by VPE-VPI(n.7/27=25,9%) (mean follow-up.7 y.,8 m.).


CONCLUSIONS
VPE: Indicated in selected cases with IVCS and IVCP. In IVCP VPE-VPI are preferable than other procedures. Atypical and autologous VPI represents a technical progress in valveless syndromes.
