Introduction:
The patterns of recurrent varicose veins after endovascular ablation of the saphenous veins are not well described.
Methods:
The current study describes the ultrasound defined recurrence patterns seen in 58 patients (79 limbs) who returned for evaluation of recurrent varicose veins from a cohort of 802 patients treated with endovenous laser ablation and subsequent sclerotherapy from March 2000 to March 2007 with clinical follow-up until May 2014.
Findings:
The most common ultrasound defined recurrence patterns leading to the varicose veins were new reflux in the anterior accessory saphenous and small saphenous veins as well as recanalization of the treated saphenous segment. Neovascularization at the saphenofemoral junction and incompetent perforating veins as the source of the recurrent veins were not seen.
Conclusions:
The patterns of recurrence following thermal ablation of saphenous veins are different to those seen after surgery. Specifically, new reflux in other saphenous veins is responsible for most recurrent varicose veins and neovascularity seems to be unusual following endovenous laser ablation.
