Effect of Doppler ultrasound in the treatment of venous leg ulcer by foam sclerotherapy for perforating veins closure / 国际外科学杂志

ABSTRACT

Objective To evaluate the clinical effects of color Doppler ultrasound in perforating vein closure by foam sclerotherapy for the treatment of venous leg ulcer.Methods Choosing the patients with venous ulcers (classified as C6) that underwent superficial and perforating veins closure by ultrasound-guided foam sclerotherapy in the Department of Vascular Surgery,First Affiliated Hospital of Chongqing Medical University,during December 2014 to August 2016.All patients were followed up by color Doppler scanning for veins closure,and the postoperative healing of skin ulcers were observed at the same time.Results A total of 114 patients with 119 limbs were enrolled,which were confirmed 1-3 perforating vein lesions by ultrasound.An average of 2.1 perforators were closed per leg (1-3 perforators).The average follow-up period was 11.3 months (1-21 months).The healing rate is 100％ and all the insufficient perforating veins were occlusion 1 month postoperative.Three cases of ulcer recurrence,and 8 cases of insufficient perforator recanalization were found.Serious complications did not appear.Conclusions Color doppler ultrasound can improve the safety and efficacy of perforating vein closure by foam sclerotherapy for the treatment of venous leg ulcer,and it has a high clinical value.
