Eight-year follow-up of a randomized clinical trial comparing ultrasound-guided foam sclerotherapy with surgical stripping of the great saphenous vein.

BACKGROUND: This was an 8-year follow-up of an RCT comparing ultrasound-guided foam sclerotherapy (UGFS) with high ligation and surgical stripping (HL/S) of the great saphenous vein (GSV). METHODS: Patients were randomized to UGFS or HL/S of the GSV. The primary outcome was the recurrence of symptomatic GSV reflux. Secondary outcomes were patterns of reflux according to recurrent varices after surgery, Clinical Etiologic Anatomic Pathophysiologic (CEAP) classification, Venous Clinical Severity Score (VCSS) and EuroQol Five Dimensions (EQ-5D™) quality-of-life scores. RESULTS: Of 430 patients originally randomized (230 UGFS, 200 HL/S), 227 (52·8 per cent; 123 UGFS, 103 HL/S) were available for analysis after 8 years. The proportion of patients free from symptomatic GSV reflux at 8 years was lower after UGFS than HL/S (55·1 versus 72·1 per cent; P = 0·024). The rate of absence of GSV reflux, irrespective of venous symptoms, at 8 years was 33·1 and 49·7 per cent respectively (P = 0·009). More saphenofemoral junction (SFJ) failure (65·8 versus 41·7 per cent; P = 0·001) and recurrent reflux in the above-knee GSV (72·5 versus 20·4 per cent; P = 0·001) was evident in the UGFS group. The VCSS was worse than preoperative scores in both groups after 8 years; CEAP classification and EQ-5D® scores were similar in the two groups. CONCLUSION: Surgical stripping had a technically better outcome in terms of recurrence of GSV and SFJ reflux than UGFS in the long term. Long-term follow-up suggests significant clinical progression of venous disease measured by VCSS in both groups, but less after surgery.

Surgery and endovenous techniques for the treatment of small saphenous varicose veins: a review of the literature.

In 15% of all patients, varicosis is caused by insufficiency of the small saphenous vein (SSV). In the past it was common to entirely remove the SSV by surgical procedure; however, recently minimally invasive techniques have taken over a significant number of varicose vein treatments. The aim of this paper is a review of the literature of all treatment modalities of the insufficient SSV. The search aimed to identify all papers published describing one or more treatments for SSV insufficiency. International literature databases were searched through for articles eligible for this review. Articles describing one or more treatment techniques for SSV insufficiency were eligible for this review. Also studies describing SSV as well as greater saphenous vein were included as long as they made a clear distinction in their results between the two groups. Studies were excluded if they did not use ultrasound examination to qualify outcome, as this is the golden standard to evaluate venous insufficiency. Seventeen articles were included in this review. Five articles on surgical treatment showed success rates varying from 24% to 100% (follow-up 1.5-60 months). Ten articles on endovenous laser ablation (EVLA) showed success rates varying from 91% to 100% (follow-up 1.5-36 months). Two articles on ultrasound-guided foam sclerotherapy (UGFS) showed success rates varying from 82% to 100% (follow-up 1.5-11 months). Statistical analysis showed a significant difference (P < 0.05) in success rate of 47.8% versus 94.9% for surgery and EVLA/UGFS, respectively. Most complications for all treatment techniques were mild and self-limiting. Rates of deep venous thrombosis were not described often and in the articles that mentioned it, varied from 1.8% to 3.5% (surgery) and 2.5-5.7% for EVLA. In the absence of large, comparative randomized clinical trials, minimally invasive techniques appear to have a tendency towards better results than surgery, in the treatment of the insufficient SSV.

Blocking the saphenofemoral junction during ultrasound-guided foam sclerotherapy-- assessment of a presumed safety-measure procedure.

OBJECTIVES: Ultrasound-guided foam sclerotherapy (UGFS) is a technique in which a mixture of sclerosing drug and gas is used to treat varicose veins. Several authors have demonstrated transient systemic effects after UGFS. These effects are not well understood but probably originate from a systemic distribution of the sclerosing foam. Therefore, safety measures have been developed to prevent foam from flowing into the deep venous system. The aim of the study is to evaluate whether blockage of the saphenofemoral (SF) junction by either manual compression or surgical ligation prevents microbubbles from leaking into the deep venous circulation. METHODS: To detect the distribution of microbubbles, radioactive pertechnetate (99mTcO4-) was added to the foam solution. Initially, in vitro trials were performed in the laboratory to investigate the effect of 99mTc on foam stability. The time taken for foam to liquefy was measured for foam alone and for the mixture with 99mTc. In subsequent research, eight varicose great saphenous veins (GSVs) were treated by UGFS. In three patients, this treatment was preceded by surgical ligation of the SF junction. In three patients, the groin was manually compressed during UGFS. In two patients, UGFS was performed without compression of the groin. RESULTS: In vitro, 99mTc did not influence foam stability; after 2.6 min all foam had reduced to liquid, regardless of whether 99mTc had been added or not. In vivo trials showed that all patients showed a decrease in the cumulative amount of 99mTc detected in the GSV following polidocanol-99mTc mixture injection. However, the decrease of radioactivity was slightly reduced when compression or ligation of the SF junction was performed. CONCLUSIONS: Blocking the SF junction during UGFS using either manual compression or ligation does not prevent, but may reduce the flow of foam into the femoral vein.

Two Dutch brothers with Borrone dermato-cardio-skeletal syndrome.

In 1993, Borrone et al. described two Italian brothers affected by a syndrome of severe acne, mitral valve prolapse, dysmorphic facies, and Scheuermann-like changes of the vertebral column. Since then, no further cases have been reported. Here, we report on two Dutch brothers with many features suggestive of this rare syndrome.
