[Retrograde mechanochemical ablation of the great saphenous vein in treatment of stage III chronic venous insufficiency].

Presented herein is a clinical case report regarding successful treatment of a trophic ulcer of the right tibia by means of endovenous mechanochemical ablation of the great saphenous vein using the FlebogrifTM device. According to ultrasonography findings, the patient was found to have insufficiency of the saphenofemoral junction, axial truncal reflux, and the absence of incompetent perforator veins in the area of trophic disorders. Taking into account the clinical and ultrasound picture of the disease, the decision was made on the feasibility of performing crossectomy and retrograde mechanochemical ablation of the great saphenous vein. The chosen modality of the invasive intervention did not require tumescent anesthesia, allowed a catheter to be placed under the ulcer bed and, unlike thermal methods, excluded the risk of damage to the subcutaneous nerves and soft tissues. The operation made it possible to eliminate pathological truncal reflux along the entire length, which contributed to rapid healing of the trophic ulcer, relief of varicose disease symptoms, and significant improvement of the patient's quality of life. This clinical case report indicates the possibility of application of retrograde endovenous mechanochemical ablation in a patient with varicose disease, axial reflux and open venous ulcer (C6) and warrants further research in this direction.
