PURPOSE: To report the midterm results of mechanochemical ablation (MOCA) for treating great saphenous vein (GSV) insufficiency. METHODS: In a 1-year period, 85 consecutive patients (median age 51.4 years; 71 women) undergoing MOCA with polidocanol in 104 limbs were enrolled in a prospective registry. The patients were evaluated at baseline and during follow-up (4 weeks and 1, 2, and 3 years) using duplex ultrasound, the CEAP (clinical, etiologic, anatomic and pathophysiologic) classification, the Venous Clinical Severity Score (VCSS), the RAND Short Form 36-Item Health Survey (RAND-SF36), and the Aberdeen Varicose Vein Questionnaire (AVVQ). Primary outcome measures were clinical and anatomic success. Secondary outcome measures included general and disease-specific quality of life and reinterventions. RESULTS: Technical success (99%) was achieved in all but 1 patient in whom technical problems with the device led to conversion to another method for treatment of 2 limbs. After a median follow-up of 36 months (interquartile range 12.5, 46.3), recanalization occurred in 15 (15%) of 102 successfully treated vein segments. Anatomic success was 92%, 90%, and 87% after 1, 2, and 3 years, respectively. The VCSS improved at all time intervals compared to the preprocedure median. The clinical success at 3 years was 83%. The AVVQ and RAND-SF36 scores showed an improvement at all time intervals compared to baseline values. Between 12 and 36 months, however, a significant deterioration was observed in VCSS, which was accompanied by worsening of disease-specific and general quality of life. CONCLUSION: In the longest follow-up of MOCA to date, this study shows MOCA to be an effective treatment modality for GSV insufficiency at midterm follow-up, but clinical results seem to drop over time.
