Abstract
Purpose
The therapeutical management of low-flow vascular malformations (LFVMs) is challenging because of high recurrence rate; multiple strategies have been proposed. This paper aims to report a single-center experience of direct puncture sclerotherapy of peripheral LFVMs, focusing on technical aspects and clinical outcome in mid-term follow-up.
Materials and methods
16 patients have been treated for peripheral LFVMs (mean age 36.1 years), complaining mild pain, swelling of the region of interest, and cosmetic nuisance. Preprocedural US and MR were acquired; angiography performed only in doubt vascular supply. Standard procedure consisted of direct puncture of the nidus using 20–23 gauge needles under US guidance and injection of up to 15 ml foam of sodium tetradecyl sulphate under fluoroscopic guidance. Clinical and radiological follow-up were assessed at 1, 3, and 6 months.
Results
Lesions were localized: 8 in the upper and 5 the in lower limbs, 2 in the cheeks, and 1 in the vaginal labia. All procedures have been technically accomplished (100%). At 6 month follow-up, technical and clinical success were obtained in all cases, while radiological follow-up showed 81.2% (13 patients) complete vessels thrombosis after multiple sclerotherapy sessions. No major complications have been recorded; five patients (31.2%) referred minor complications.
Conclusions
Sclerotherapy via direct puncture of LFVMs is a clinically effective procedure, well tolerated by patients, with reduced costs and mild minor complications rate; interventionalists should always clarify to the patients that multiple sessions would be performed and recurrences are expected at imaging follow-up despite clinical improvement.
