First, a local anesthetic is injected to ensure comfort during the process. Then a fiber or electrode is moved to the desired location within the vein through the small incision, using an ultrasound to guide the location. A solution is injected into the tissues around the vein to collapse the vein around the fiber or electrode and act as insulation for the energy’s heat. The heat causes the vessel to close and shrink. A follow-up ultrasound exam is performed, while at Portland Pain and Spine, to check for any adverse outcomes. The follow-up is mandatory and included in the cost.
