Can phlebectomy be deferred in the treatment of varicose veins?
OBJECTIVE
This study was designed to observe the clinical sequelae of varicose veins after great saphenous vein (GSV) ablation and to assess possible predictability of spontaneous varicose vein regression.


METHODS
Patients with symptomatic varicose veins secondary to GSV insufficiency treated with radiofrequency ablation (RFA) were enrolled in the study. Up to five of the largest varicose veins in each limb were mapped, sized, and documented before RFA. No varicose vein was treated either at the time of RFA or within 6 months postoperatively. Varicose vein status was recorded at follow-up visits.


RESULTS
Fifty-four limbs in 45 patients were included. A total of 222 varicose veins were documented before RFA (4.1 +/- 1.1 varicose veins per limb) with an average size of 11.4 +/- 3.7 mm. During the follow-up period, complete resolution of visible varicose veins was seen in 13% of limbs after RFA alone, and 63 (28.4%) varicose veins spontaneously resolved. A further 88.7% (141/159) of varicose veins decreased in size an average of 34.6% (4.3 +/- 3.4 mm). Preoperatively, 19.4% of varicose veins were above the knee and 75.7% were below the knee. Complete varicose vein resolution was 41.9% (18/43) above the knee and 25.6% (43/168) below the knee. For the above-knee varicose veins, 88.4% (38/43) were located medially, and all the resolved ones (47.4%, 18/38) were medial varicose veins. Resolution rates of the 168 below-knee varicose veins were 30.6% (33/108) of medial, 23.1% (6/26) of anterior, 20.0% (3/15) of lateral, and 5.3% (1/19) of posterior.


CONCLUSIONS
Great saphenous vein ablation resulted in subsequent resolution or regression of many lower-limb visible varicose veins. With further study, the predictability of varicose vein regression may perhaps be increased, which can then direct the treatment strategy to further leverage the advantages of minimally invasive endovenous procedures.
