| Summary: | Mini-invasiveness, ease of use and execution speed represent the reasons for endovenous laser ablation success. Nevertheless, the strategic choice remains the ablation of the saphenous trunk. Hemodynamic correction (CHIVA) represents an option, based on a saphenous-sparing therapeutic strategy. We tested the feasibility of a modified CHIVA strategy by means of endovenous lasers (EL) shrinkage of segmental great saphenous vein (GSV) tracts, in networks characterized by sapheno-femoral incompetence and re-entry perforators focused on the GSV. We report the follow up of the first 2 chronic venous disease [C<sub>1,2,3</sub>sEpAsPr<sub>1,2,3</sub>, venous clinical severity score (VCSS) 8 and 9 respectively] treated cases. At 1-year follow up both patients were C<sub>1,2,3</sub>sEpAsPr<sub>1,2,3</sub> and the VCSS were 1 and 2 respectively. The non-treated GSV tracts maintained their patency. ELs were herein used within a saphenous-sparing therapeutic plan, thanks to an accurate pre-operative hemodynamic assessment, which allowed the shrinkage of only the first saphenous trunk tract only. Proper technical and hemodynamic considerations are discussed.
