Endovenous ablation has become the preferred means to treat superficial venous insufficiency. Ablative technologies have evolved to include a variety of both thermal and non-thermal techniques. The reported thrombotic complications of endovenous heat induced thrombosis (EHIT) and deep venous thrombosis (DVT) associated with thermal techniques are low (<2% overall). However, the limited data on newer non-thermal technologies suggest these modalities may have thrombotic complication rates upwards of 6%. Additionally, the pathophysiology of thrombotic events related to mechanochemical ablative techniques may differ from EHIT, and thus, may have different implications for management. Described is a case report of a stroke after cyanoacrylate ablation of the great saphenous vein, and a review of the current literature reporting the thrombotic complications associated with current thermal and non-thermal techniques. There exists a need for high-volume studies on newer ablative techniques to fully understand their associated thrombotic complications. This review highlights the need for a comprehensive classification system and standard treatment algorithm encompassing of thrombotic complications associated with both thermal and non-thermal ablative techniques.
