Efeitos da escleroterapia de varizes com espuma: parâmetros de refluxo no ultrassom com doppler

Abstract

Context: Chronic venous insufficiency (CVI) is one of the most prevalent chronic diseases, accounting for an important morbidity in the western world. Objective: Evaluate the effects of foam sclerotherapy using colored Doppler ultrasonography reflux parameters. Methods: A before and after study was used, nested in a randomized controlled trial, conducted between October 2013 and August 2015. Patients underwent foam sclerotherapy sessions in varicose veins with CEAP from 2 to 6. They were reassessed three weeks after their session with Doppler ultrasonography. Treated segment occlusion as well as reflux absence was analyzed, and also complications related to the procedure. Results: 135 limbs of 92 patients were treated, 95% of these were women, average age was 50.45 years old and average BMI was 32.54. Complete occlusion was observed in 53% of the treated segments and reflux improved in 70.1% three weeks after the procedure. Most complications were nodules and hyperchromic skin lesions. Conclusion: These results showed improvement of the ultrasonographic parameters after varicose veins treatment with foam sclerotherapy. Complications were, mostly, benign and around the expected rates.
