ABSTRACT

OBJECTIVE: To clarify the role of clinical anatomy of foot and ankle perforator veins (PV) in surgical treatment of varicose vein disease. MATERIAL AND METHODS: Anatomy of foot and ankle PV was assessed in 50 amputated lower extremities by anatomical dissection. RESULTS: There were 4-6 PVs at the medial surface of the foot. These veins connected medial marginal vein and vv. plantaris medialis (VPM). There were 2-3 PVs at the lateral surface of the foot. These veins connected lateral marginal vein and vv. plantaris lateralis (VPL). All PVs on the lateral surface of the foot constitute the neurovascular bundles. PVs flowing into vv. dorsalis pedis are localized on the medial surface of the medial marginal vein at the level of the ankle base. In most cases, we found an arterial branch nearby at the subfascial level. In anterior part of the plantar surface of the foot, we distinguished 4-5 small PVs (~1 mm) flowing into vv. digitales plantares through the commissural orifices of the aponeurosis. There were 6-9 vessels (~1 mm) along the fascial aponeurotic septa. These vessels connected superficial plantar venous network and plantar veins. Small arterial branch was found almost in all cases near these veins. Noteworthy is the area where the plantar veins lie on the quadratus plantae and are covered by a leaf of deep plantar fascia. This anatomy is similar to topography of posterior tibial veins. CONCLUSION: Foot perforator veins constitute the neurovascular bundles as a rule. Plantar vein topography and their relationship with PV confirm an existence of muscular-venous pump of the foot.
