Transient Thrombocytosis after Endovenous Laser Treatment for Primary Varicose Vein of the Lower Extremity

Abstract

We presented a case of a completely occluded great saphenous vein and transient thrombocytosis following endovenous laser treatment (EVLT) for primary varicose veins of the lower extremity. A 54-year-old man with a left saphenous varicose vein underwent EVLT surgery. Twelve-watt laser irradiation was delivered over the length of 33 cm of the saphenous vein. The cumulative exposure was 1042 J. Nine days after treatment, the platelet count increased up to 610 × 10³ /mm³ and returned to normal after 2 months. A complete occlusion of the great saphenous vein commonly occurs after EVLT, but no case of transient thrombocytosis has been reported.
