Abstract
OBJECTIVE
Endothermal ablation as endothermal laser ablation (EVLA) or Radiofrequency ablation (RFA) is being progressively more employed for small saphenous vein (SSV) insufficiency treatment. Prior studies have shown recurrence rates of 0% to 10% in incompetent small saphenous veins (ISSVs). The objective of this study is to determine the efficacy of redo venous ablations for symptomatic recanalized SSVs and to predict factors related with recanalization.
METHODS
A retrospective analysis of 2,566 procedures in 1,752 patients with CVI due to ISSVs from 2012 to 2018 was performed, using individual chart review for data extraction. All 2,566 procedures were performed using endothermal ablation in patients who failed initial conservative management. Postoperative duplex ultrasound scans were performed within 3 to 7 days. We defined a successful obliteration as a lack of color flow by postoperative duplex scan. We defined recanalization as the presence of reflux on duplex ultrasound in the target vessel at follow-up. We conducted follow-ups every 3 months in the first year, followed by every 6 months subsequently.
RESULTS
Among the 2,566 procedures, redo ablation was performed in 91 ISSVs (86 patients), including 58 women and 28 men. 54 procedures were performed on the left lower extremity, 37 were performed on the right lower extremity. The average Body Mass Index (BMI) was 32.2 ± 7.66. The mean age was 62.4 ± 15.10 years. Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) classes of the patients were: C1, 0; C2, 0; C3, 29; C4, 43; C5, 1; and C6, 18. The mean maximum diameter of the targeted veins, for the redo procedures, was 4.51± 1.33 mm. Forty procedures were performed using EVLA, 51 were performed using RFA. Initial technical success was 98.9%. Redo procedures had an early closure of 96.7%. At follow up after a mean duration of 24.9 ± 14.9 months, closure was 96.5%. No correlation was found between successful obliteration in the redo procedure and age, gender, CEAP, laterality, EVLA vs. RFA, BMI, or vein diameter.
CONCLUSIONS
Rates of successful closure for ISSVs on initial and redo procedures are comparable. The data validate the potential usefulness of performing redo SSV ablations.
