BACKGROUND: Among vascular anomalies, congenital venous malformations (VMs) are the most common lesions. Treatment of VMs is sometimes difficult or cumbersome, depending on their size and tissue involvement. Surgery may lead to invasive and mutilating excisions, often allowing only partial removal, with an increased risk of recurrence. Sclerotherapy is a mainstream technique, resulting in endothelium destruction, fibrosis, and subsequent shrinkage of the vascular lesion, also with a risk of recurrence. However, this technique may not be efficient in cases of large and infiltrating VMs. Endovenous thermal ablation has been found to be more effective than sclerotherapy for transmural vascular destruction and has therefore been employed in the treatment of VMs.
MATERIALS AND METHODS: In this observational retrospective case series, we describe a combined technique for the treatment of large intramuscular VMs in seven consecutive patients, associating endovenous laser ablation with sclerotherapy. Aim is to assess feasibility and safety of the procedure.
RESULTS: In these small series, we report a high immediate technical success, clinical and radiological improvement, with no complications.
CONCLUSIONS: The preliminary results presented herein show, that combining EVLA and sclerotherapy for the treatment of voluminous persistent intramuscular VM is safe and technically feasible. The combination of a wide direct intimal thermal damage with chemical sclerotherapy is the force of this approach. The small number of cases and the medium term follow up represent though a limitation.
