Burns School of Medicine Honolulu HI USA e-mail emasuda@ dkessler@ Abstract Perforator veins PVs are one of three major venous systems in the leg directly linked to serious manifestations of chronic venous disease CVD including venous ulceration. Although its anatomical details are clearly defined the physiology and clinical importance of PVs continue to remain less explicit. This chapter will review the evidence to support the diagnosis indication for treatment noninvasive and invasive options for management of PVs. Introduction Nearly 100 years ago Homans presented a comprehensive description of the relationship between perforator veins and leg ulceration 1 . Despite its long history and the fact that perforator veins are frequently identified in the gaiter area beneath ulcers and areas of venous stasis dermatitis controversy still prevails over its clinical significance and role in producing the pathologic state. Additionally choices for treatment are highly variable and range from invasive eradication by long calf incisions to simple ablation by direct injections. This chapter will attempt to clarify the role of PVs in CVI and discuss the optimal diagnostic and therapeutic strategies. E. .
