Currently, minimally invasive treatment including ultrasound-guided foam sclerotherapy (UGFS) is widely applied. However, in our country, the report concerning about UGFS is extremely rare. Between January 2018 and April 2019, we have performed UGFS for the residual or recurrent varices of 55 limbs in 51 patients after endovascular thermal ablation or surgery. The injection sites of sclerosant, using 1–3% polidocanol foam (<1 mL) are as follows; Incompetent perforator below the knee 10 cases, saphenous vein (Great 12, Short 8), saphenous tributary vein 2, accessory saphenous vein 1 and Giaconomi vein 1 case, respectively. After sclerotherapy, the compression was continued using bandage with pads overnight, then elastic stockings at least one month. The Doppler ultrasound examination has revealed that the venous reflux was disappeared 52 of 55 limbs 4 weeks later (28–35 day) post-sclerotherapy. The reflux remaining three cases was due to incomplete compression without elastic stocking, but residual reflux was disappeared by the additional sclerotherapy. The UGFS is effective and safe strategy for residual or recurrent varices, because no complication has occurred during follow up period ;mean 10.2 month post-sclerotherapy.
