The FPV is a specific anatomic vein with standard relations to other anatomic structures and may become involved in varicose vein disease. FPV incompetence escapes clinical diagnosis but is easily detected by duplex ultrasound. The incompetent FPV can be avulsed by ambulatory phlebectomy (Muller technique) in an office setting under local infiltration anesthesia.

Routine preoperative duplex evaluation is mandatory if varicose vein surgery is to be done on patients with accurate diagnosis.
