Abstract

Objectives: Describe imaging characteristics of soft tissue venous malformation on digital subtraction angiography (DSA) and evaluate the effectiveness of absolute ethanol.Methods: Retrospective and prospective cohort from July 2020 till May 2022 on 34 patients treated by DSA-guided percutaneous sclerotherapy using absolute ethanol. Patients after the intervention were followed up and evaluated the results of the sclerotherapy method after one month and three months later based on the following parameters: percentage of sclerosing of malformation and VAS pain score (Visual Analog Scale) pre-and post-treatment. The data is analyzed and processed by using SPSS 20.0. Results: The study includes thirty-four patients (9 men and 24 women) with soft tissue venous malformations. The mean age was 29.6 ± 16.9 years (range from 10 to 64 years). The classification of the malformation was analyzed based on the features of drainage venous, which was classified according to the classification of Puig et al. 2003. Among 34 lesions, there were 5/34 type I (14.7%), 24/34 type II (70.6%), 3/34 type III (8.8%), and 2/34 type IV lesions (5.9%). The total number of treatment sessions was 63, with 79.4% of patients having a sclerosed malformation percentage above 50% and 20.4% of patients having less than 50% sclerosed malformation percentage. After treatment, 94.1% of patients had an improvement in pain level, of which 95.7% of patients with moderate and severe pain improved their pain level to a mild pain level, with only one patient (4.3%) maintaining severe pain levels. Conclutions: DSA-guided sclerotherapy using absolute ethanol is an effective technique for treating soft tissue venous malformations.
