Radiofrequency obliteration in treatment of venous angiodysplasia

Abstract

Aim. This study aimed to investigate potential use of radiofrequency obliteration (RFO) of angiomatous tissues in patients with venous malformations.

Materials and Methods. A single-center study retrospectively involved 42 clinical cases [57.1% of men (n=24), aged 18-44 years; 42.8% of women (n=18) aged 18-56 years] of venous angiodysplasia, with a total of 46 interventions using RFO. Clinical manifestations of the disease were primarily characterized by pain syndrome (71.4%), cosmetic defect (100%), and edema syndrome (95.2%).

Results. Clinical improvement was possibly achieved with the reduction of the intensity of manifestations of angiomatous processes in 37 patients (88.1%). Stable and partial obliterations of caverns in the zone of exposure to radiofrequency were recorded in 37 (88.0%) and 5 (12.0%) patients, respectively. In caverns with small diameter, obliteration was achieved in 100% of the cases. Postoperative complications included bleeding (2.4%), burns in the zone of electrode introduction (2.4%), lymphorrhea (2.4%), and hypesthesia (2.4%). With this, according to the results of duplex scanning performed on control visits, no significant disease progression was observed. In the same patient, several complications could occur. All complications regressed within a month and required no treatment in hospital conditions.

Conclusion. RFO showed advantage as a minimally invasive treatment method of venous angiodysplasias. Results suggest that RFO can be recommended for use in patients with >1 cm depth of lesion with caverns of medium and large diameter as an independent treatment method and in combination with standard resection methods.
