摘要：
Improved systems and methods for removing blood from a blood vessel in preparation for endovenous laser ablation are described. The improved methods include one or more of: placing the patient in the Trendelenburg position, applying external compression around the vein, massaging the vein, cooling the vein externally, encouraging spasming of the vein, and removing blood with a suction device.
