Ultrasound-guided foam sclerotherapy combined with sapheno-femoral ligation compared to surgical treatment of varicose veins: early results of a randomised controlled trial.

AIM: This study is a prospective randomised controlled trial comparing sapheno-femoral ligation, great saphenous stripping and multiple avulsions with sapheno-femoral ligation and ultrasound guided foam sclerotherapy to the saphenous vein. Primary end points were patient recovery period and quality of life and secondary end points frequency of complications on the two arms of the trial and the cost of the treatment. MATERIAL AND METHOD: Sixty patients with primary varicose veins due to GSV incompetence and suitable for day case surgery were randomly allocated to undergo ultrasound-guided sclerotherapy with sapheno-femoral ligation under local anaesthesia (n=30) or sapheno-femoral ligation, stripping and multiple avulsions under general anaesthesia (n=30). The study protocol included history, physical examination, assignment of CEAP class and assessment venous clinical severity score (VCSS), completion of the aberdeen vein questionnaire (AVQ) and colour duplex ultrasound. RESULTS: All treatments were completed as intended. Median time to return to normal activities was significantly reduced in the foam sclerotherapy group (2 days) compared to the surgical group (8 days) (p<0.001, Mann-Whitney). AVQ score was also significantly reduced at 3 months by 46% in the sclerotherapy group, and by 40% in the conventional surgery group (p<0.001, Wilcoxon). The time taken to complete treatment was shorter in the foam sclerotherapy plus SFJ ligation group: 45 vs. 85 min (p<0.001, Mann-Whitney). The overall cost of the procedure in the sclerotherapy group ( 672.97 pounds) was significantly less compared to conventional surgery ( 1120.64 pounds). At 3 weeks, there was no statistical difference in the complication rate between the two groups. At 3 months, median CEAP class dropped from four pre-operatively to one following treatment in both groups and the median VCSS score dropped from five to one in group one and from seven to three in group two (p<0.001, Wilcoxon test). In group one four patients (13%) had a recanalised vein which needed further sessions of foam sclerotherapy, resulting in a short-term closure rate of 87%. CONCLUSION: Ultrasound guided sclerotherapy combined with sapheno-femoral ligation was less expensive, involved a shorter treatment time and resulted in more rapid recovery compared to sapheno-femoral ligation, saphenous stripping and phlebectomies.     

Efficacy and safety of great saphenous vein sclerotherapy using standardised polidocanol foam (ESAF): a randomised controlled multicentre clinical trial.

AIM: To assess the safety and efficacy of sclerotherapy of the great saphenous vein (GSV) comparing standardised polidocanol foam to liquid polidocanol in a randomised controlled trial (RCT). METHODS: A multicentre randomised controlled clinical trial was carried out in which saphenous trunks were treated by sclerotherapy. 106 patients with primary varicose veins due to an incompetent GSV were treated with either standardised 3% polidocanol foam or 3% liquid polidocanol. The primary efficacy criterion was elimination of reflux (<0.5 sec) measured 3 cm below the sapheno-femoral junction (SFJ) by duplex ultrasonography 3 months after the last injection. RESULTS: A significantly greater number of patients were successfully treated by foam sclerotherapy resulting in 69% elimination of reflux compared to 27% patients treated with liquid sclerosant. The secondary endpoints of vein occlusion, reflux time, refilling time and patient satisfaction also improved significantly more in the foam group. The mean number of treatment sessions was 1.3 in the foam group compared to 1.6 in the liquid group. Differences between study centres occurred with a mean of 96% reflux elimination in 6 centres versus 39% in 4 other centres. Centres with a high response rate injected a higher mean volume (4.3 vs. 3.6 ml) in the first session in a vein with a smaller diameter (7.5 mm vs. 8.4 mm). No difference in adverse drug reactions was observed between treatment groups. CONCLUSIONS: Standardised 3% polidocanol foam is more efficient and equally safe compared to 3% liquid polidocanol for treatment of GSV. In comparison to other studies a relatively small volume was injected into relatively large veins.     

Ultrasound findings after radiofrequency ablation of the great saphenous vein: descriptive analysis

OBJECTIVE: As an emerging endovascular alternative to ligation and stripping of the incompetent greater saphenous vein (GSV), radiofrequency ablation was monitored with ultrasound scanning to evaluate anatomic results. Neovascularization and inflammation are potential consequences that lead to the appearance of small vessels. The natural history of the below-knee untreated GSV segment may be important in our understanding of ongoing chronic venous disease. An ultrasound follow-up study was conducted to determine the prevalence of small vessel networks, defined as veins and arteries less than 2 mm in diameter, adjacent to the saphenofemoral junction (SFJ); prevalence of small vessel networks adjacent to the treated GSV in the thigh; and fate of the below-knee untreated GSV distal to the ablated segment. METHODS: One hundred six extremities with radiofrequency ablation of the GSV for treatment of superficial venous insufficiency were followed up with high-resolution ultrasound imaging 4 to 25 months (median, 9 months) after the procedure. Ninety-three limbs had concomitant ligation and division of the SFJ and its tributaries, and 13 limbs underwent radiofrequency ablation without SFJ ligation. Ultrasound was used to evaluate patients for small vessel networks, and concomitant findings of small vessel networks and recanalization at the SFJ and adjacent to the treated GSV. The status of the below-knee segment of untreated GSV was evaluated for patency and reflux. Data analysis compared the findings in the ligation group with those in the no-ligation group, with the chi 2 test and Fisher exact test. RESULTS: We found small vessel networks in 65% (n = 69) of extremities: 15% (n = 16) at the SFJ only, 26% (n = 28) in the thigh only, and 24% (n = 25) at both the SFJ and thigh, resulting in a small vessel network prevalence of 39% (n = 41) at the SJF and 50% (n = 53) in the thigh. The prevalence of small vessel networks at the SFJ was significantly less after radiofrequency ablation with SFJ ligation (34%, 32 of 93) than after radiofrequency ablation without ligation (69%, 9 of 13; P = .035). Small vessel networks and GSV recanalization at the SFJ was more common in patients undergoing radiofrequency ablation without ligation (46%, 6 of 13) than after radiofrequency ablation with ligation (14%, 13 of 93; P = .014). The prevalence of small vessel networks in the thigh was not affected by SFJ ligation. The below-knee GSV was patent in 79% (84 of 106), and 58% (61 of 106) demonstrated reflux, a decrease from the pre-radiofrequency ablation rate of 71% (75 of 106), possibly because thrombosis extended distally beyond the ablated segment in 16% (17 of 106) of the legs. CONCLUSIONS: Small vessel networks were detected adjacent to or in connection with most of the radiofrequency ablation-treated GSVs. SFJ ligation was associated with fewer small vessel networks and proximal GSV recanalization. Most below-knee untreated GSV segments remained patent, and most exhibited reflux.     

Defining the role of extended saphenofemoral junction ligation: a prospective comparative study

OBJECTIVE: This study explores the added effect of extended saphenofemoral junction (SFJ) ligation when the greater saphenous vein (GSV) has been eliminated from participating in thigh reflux by means of endovenous obliteration. GSV obliteration, unlike surgical stripping, can be done with or without SFJ ligation to isolate and study SFJ ligation's specific contribution to treatment results. METHODS: Sixty limbs treated with SFJ ligation and 120 limbs treated without high ligation were selected from an ongoing, multicenter, endovenous obliteration trial on the basis of their having primary varicose veins, GSV reflux, and early treatment dates. RESULTS: Five (8%) high-ligation limbs and seven (6%) limbs without high ligation with patent veins at 6 weeks or less were excluded as unsuccessful obliterations. Treatment significantly reduced symptoms and CEAP clinical class in both groups (P =.0001). Recurrent reflux developed in one (2%) of 49 high-ligation limbs and eight (8%) of 97 limbs without high ligation by 6 months (P =.273). New instances of reflux did not appear thereafter in 57 limbs followed to 12 months. Recurrent varicose veins occurred in three high-ligation limbs and four limbs without high ligation by 6 months and in one additional high-ligation limb and two additional limbs without high ligation by 12 months. Actuarial recurrence curves were not statistically different with or without SFJ ligation (P >.156), predicting greater than 90% freedom from recurrent reflux and varicosities at 1 year for both groups. CONCLUSION: These early results suggest that extended SFJ ligation may add little to effective GSV obliteration, but our findings are not sufficiently robust to warrant abandonment of SFJ ligation as currently practiced in the management of primary varicose veins associated with GSV vein reflux.     

Reflux elimination without any ablation or disconnection of the saphenous vein. A haemodynamic model for venous surgery.

OBJECTIVES: to investigate the possibility of the haemodynamic suppression of reflux in the greater saphenous vein (GSV) without any high ligation and/or stripping procedure. DESIGN: prospective study; single group of patients. MATERIALS: forty patients affected by primary chronic venous insufficiency of all clinical classes, with demonstrated duplex incompetence both of the sapheno-femoral junction (SFJ) and the GSV trunk, with the re-entry perforator located on a GSV tributary. The re-entry point was defined as the perforator, whose finger compression of the superficial vein above its opening eliminates reflux in the GSV. METHODS: air-plethysmographic parameters as well as duplex scanning were performed both preoperatively, and 1 and 6 months later, respectively. Operation consisted in flush ligation and division from the GSV of the tributary containing the re-entry perforating vein. RESULTS: duplex investigation demonstrated both a forward flow and reflux disappearance in the GSV in 100% and 85% of the cases after 1 and 6 months, respectively. All air-plethysmographic parameters, with the exception of Ejection Fraction, improved significantly: Venous Volume changed from 150+/-9 ml to 114+/-7 ml (p <0.0001), Venous Filling Index from 4.9+/-0.5 ml/s to 2.3+/-0.2 ml/s ( p <0.0001), and Residual Volume Fraction from 42+/-3 ml to 30+/-2 ml ( p <0.0001). CONCLUSIONS: this study demonstrates that reflux in the GSV system is supported by a gradient of pressure between the anatomical point of reflux and the point of re-entry in the deep veins. Disconnection of the flow to the re-entry perforator without high ligation of the sapheno-femoral junction suppresses GSV reflux.     

Durability of reflux-elimination by a minimal invasive CHIVA procedure on patients with varicose veins. A 3-year prospective case study.

OBJECTIVES: to assess the outcome of a conservative and haemodynamic method for insufficient veins on an ambulatory basis (French acronym, "CHIVA") with preservation of the greater saphenous vein (GSV) for treatment of primary varicose veins. METHODS: duplex incompetence of the sapheno-femoral junction (SFJ) and the GSV trunk, with the re-entry perforating point located on a GSV tributary was demonstrated in 58 patients with varices (58 limbs). The re-entry point was defined as the perforator, whose compression of the superficial vein above its opening eliminates reflux in the GSV. Duplex scanning was performed preoperatively and at 7 days, and patients were followed prospectively at 1, 3, 6, 12, 24, and 36 months after CHIVA. Operation consisted in flush ligation and division from the GSV of the tributary containing the re-entry perforating vein (no additional high ligation is included). If reflux returned, SFJ interruption was performed in a second surgical procedure. RESULTS: the GSV diameter showed an average reduction from 6.6 to 3.9 mm 36 months after surgery. Reflux in the GSV system was demonstrated in all but five (8%) patients. Of the 53 patients with recurrent reflux, 46 underwent SFJ interruption. CONCLUSIONS: elimination of reflux in the GSV after the interruption of insufficient collaterals is only temporary.     

Closure of the cribriform fascia: an efficient anatomical barrier against postoperative neovascularisation at the saphenofemoral junction? A prospective study.

BACKGROUND: Neovascularisation at the sapheno-femoral junction (SFJ) ligation site in the groin may occur within one year after great saphenous vein (GSV) surgery. Several anatomical and prosthetic barrier techniques have been proposed to prevent this evolution. OBJECTIVE: A prospective study examined whether closing the cribriform fascia could reduce the incidence of postoperative neovascularisation in the groin. PATIENTS AND METHODS: Patients with primary varicose veins and incompetence at the level of the SFJ were included. After SFJ ligation in 235 limbs of 193 patients an anatomical barrier was constructed by closing the cribriform fascia. Postoperative duplex scanning was performed after 2 and 12 months. Results were compared with historical control groups in which either a silicone patch saphenoplasty or no barrier technique had been performed. RESULTS: After one year, 10 limbs had developed recurrent thigh varicose veins and duplex scan showed neovascularisation at the SFJ ligation site in 15 of 223 re-examined limbs (6.7%). This was comparable to the group of 191 limbs with silicone patch saphenoplasty (5.2%) (P=0.526) and superior to the group of 189 limbs without barrier (14.8%) (P<0.01). CONCLUSION: Interposition of an anatomical barrier by closing the cribriform fascia after SFJ ligation reduced ultrasound detected neovascularisation at the SFJ after one year. In primary varicose vein operations application of an anatomical barrier technique (without prosthetic patch) is an alternative option to prevent postoperative neovascularisation.     

Recurrent varicose veins: incidence, risk factors and groin anatomy.

OBJECTIVES: To investigate the recurrence rate after sapheno-femoral junction (SFJ) ligation and great saphenous vein (GSV) stripping for varicose veins (VV), to evaluate risk factors for recurrence and to classify the anatomy of the recurrence in the groin. Design. Clinical follow-up study. METHODS: Eighty-nine consecutive patients with 100 operated legs were re-examined clinically and with duplex after 6-10 years. Fourteen groins were re-explored, 13 after varicography. The anatomy in the groin was classified according to the Edinburgh system. The original medical records were examined to check for risk factors which could lead to a recurrence. RESULTS: Fifty-seven legs had incompetent veins in the groin according to duplex. In 54 of them, it was possible to define whether the incompetent veins emanated from the former SFJ. Varicography and operative findings correlated well to duplex. The main difficulty was to distinguish neovascularization from residual branches. No significant risk factor for recurrence was found in the medical records. CONCLUSIONS: Recurrence of VV after SFJ ligation is common irrespective of perioperative difficulties or the surgeon's experience. The anatomy of recurrence in the groin is difficult to classify according to the Edinburgh system mainly because neovascularization is difficult to verify.
