Midterm results of radiofrequency ablation for incompetent small saphenous vein in terms of recanalization and sural neuritis.
Dermatologic Surgery : Official Publication for American Society for Dermatologic Surgery [et Al.] 2014 April
BACKGROUND: Safety and effectiveness of radiofrequency ablation for incompetent small saphenous vein is not established.
OBJECTIVE: To report midterm clinical and ultrasonograhic results of radiofrequency ablation (RFA) for small saphenous vein (SSV) in terms of recanalization and sural neuritis.
METHODS AND MATERIALS: We examined 39 patients (46 limbs) who had been examined using a duplex scan more than 1 year after RFA of SSV. Postoperative clinical results, risk factors for SSV recanalization, and sural neuritis were analyzed.
RESULTS: CEAP score and CIVIQ2 score improved significantly in all patients (CEAP: 2.45 to 1.43 (p = .03); CIVIQ2: 25.34 to 13.21 (p = .01). SSV obliteration rate was 93.4% at 1 year and 89.1% at 2 years. Preoperative peak reflux velocity in the recanalization group (54.9 cm/s) was significantly higher (p < .01) than in the obliteration group (29.8 cm/s). Sural neuritis were detected in 12 limbs(26.1%), and median symptom duration was 3 months. The total length of RFA ablation was not different between the groups with and without postablation sural neuritis.
CONCLUSION: RFA is an effective and safe treatment modality for incompetent SSV. Peak reflux velocity can be a risk factor for recanalization. Length of RFA segment in SSV does not affect recanalization and postablation sural neuritis.
