Venous Hemodynamic Changes in the Surgical Treatment of Primary Varicose Vein of the Lower Limbs

다국어 초록 (Multilingual Abstract)

Venous hemodynamic changes after the surgery of primary varicose veins were evaluated. (Materials and methods) We retrospectively analyzed 1,211 patients (1,407 limbs) who underwent surgery for primary varicose veins from 1994 to 2002. The venous hemodynamics were evaluated using air- plethysmography (APG) preoperatively and one month postoperatively in the viewpoints of ambulatory venous pressure (AVP), venous volume (VV), venous filling index (VFI), and ejection fraction (EF). (Results) The surgical modalities included 958 cases of greater saphenous vein high ligation (GSV HL) and stripping with varicosectomy (VS), 222 cases of short saphenous vein (SSV) HL and VS, 143 cases of external banding valvuloplasty of GSV and VS, and 44 cases using VNUSⓇ and VS. The reduction rate of VV was 20.9±14.1% in the GSV stripping group, 12.0±14.7% in the GSV valvuloplasty group, 18.3±16.1% in the VNUSⓇ group, and 20.6±15.9% in the SSV group. The reduction rate of VFI was 63.6±20.7% in the GSV stripping group, 38.8±40.9% in the GSV valvuloplasty group, 60.1±23.9% in the VNUSⓇ group, and 37.6±30.2% in the SSV group. The increasing rate of EF was 25.0±28.2% in the GSV stripping group, 21.0±30.0% in the GSV valvuloplasty group, 29.4±31.9% in the VNUSⓇ group, and 30.0±36.5% in the SSV group. The reduction rate of AVP was 25.4±32.2% in the GSV stripping group, -6.1±58.1% in the GSV valvuloplasty group, 28.4±38.5% in the VNUSⓇ group, and 14.1±49.0% in the SSV group. All of the patients showed improvements in venous hemodynamics by showing a decrease in VV, VFI, AVP, and an increase in EF. However, there was no difference in the change of venous hemodynamics according to the type of surgery.
