Background: We performed this single-centre prospective study, aimed to analyse the safety and efficacy of ultrasound-guided foam sclerotherapy for primary isolated small saphenous vein (SSV) insufficiency.
Methods: From June 2017 to June 2019, patients with primary SSV insufficiency and receiving ultrasound-guided foam sclerotherapy were included in this study. The collected data included demographics of patients, clinical treatment results, occlusion rate and the patient's venous clinical severity score (VCSS) before and after surgery at 6-month follow-up.
Results: A total of 26 patients (14 women and 12 men) underwent ultrasound-guided sclerotherapy in 26 lower limbs, and were followed up at 1 week, 1 month and 6 months after surgery. Short-term complications included two severe pain during injection, one with vasovagal syncope, four with hyperpigmentation and two phlebitis. During 6-month follow-up, 22 were found to have complete thrombosis, and four showed partial thrombosis. There was a clear inverse relationship between SSV occlusion and SSV diameter (r = -0.502, P < 0.05), and pre-operative VCSS evaluation (r = -0.598, P < 0.05). At the same time, there was a weak inverse relationship between SSV occlusion and the volume of foam used (r = -0.357, P < 0.05). The pre-procedural VCSS score was 8.42 ± 3.25 and the post-procedural VCSS score was 7.16 ± 3.14. Deep vein thrombosis, nerve injury and other important complications did not occur.
Conclusions: This study shows that ultrasound-guided foam sclerotherapy is a safe and effective method for symptomatic SSV insufficiency, with less adverse reactions and better effects.

Chronic venous disease has a major impact on the quality of life of millions of patients. Large randomized controlled trials have established ultrasound-guided foam sclerotherapy (UGFS) as a safe and effective treatment option for both saphenous vein insufficiency and tributary disease. Ultrasound guidance is a critical component of sclerotherapy of non-visible veins.

Background: Treatment of symptomatic varicose veins has changed dramatically in the last few years with guidelines now recommending endovenous surgery as first-line intervention. Previously, this was achieved by laser or radiofrequency ablation of the target vein, requiring infiltration of tumescent anesthesia to reduce the risks of thermal damage to surrounding tissue. Endovenous cyanoacrylate injection (VenaSeal™) is a nonthermal, nontumescent endovenous closure technique, increasing patient comfort and is readily performed under local anesthesia only and thus is a feasible technique for in-room treatment.

Article Synopsis
- Spontaneous hemorrhage from varicose veins can be a dangerous complication, and a two-step clinical protocol was developed to prevent immediate bleeding and ensure long-term results.* -
- The protocol involved a prospective registry of patients, where they received ultrasound assessments and immediate treatment through foam sclerotherapy, followed by planned endovenous ablation within eight weeks.* -
- Out of 59 patients treated, 95% had identifiable underlying issues, and while 52 received the immediate sclerotherapy, only 7 did not; results indicated no recurrent bleeding post-treatment, with a 7% rate of late hemorrhage in long-term follow-up.*
