Superficial ulnar artery is a known abnormality. It replaces the normal ulnar artery and has a superficial course. Its accidental division during the raising of the radial forearm flap can seriously jeopardize hand circulation. The presence of this vessel can be diagnosed preoperatively by careful palpation, and its course can be confirmed by vascular Doppler. This abnormality was found in 9.38 percent of upper limbs in cadaver dissections. A similar incidence of 9.12 percent was observed in clinical practice. Superficial ulnar artery gives several good-sized fasciocutaneous branches in the forearm. A type C fasciocutaneous flap, similar to a radial forearm flap, can be raised with safety on this anomalous vessel. Over the past 4 years, six such flaps have been raised. The largest fap was 24 x 12 cm. The flaps can be made neurosensory. Palmaris longus muscle can be raised with the flap for bulk or as an active motor unit. The extralong pedicle with good-sized vessels makes free-flap transfer safe. The donor site heals uneventfully. The presence of this abnormality can be a trap to an unsuspecting surgeon but is in fact a boon if diagnosed in time.

BACKGROUND: The deep veins of the leg and their associated perforating veins provide the major conduits for the return of blood from the legs to the heart. In health intrinsic valves maintain a one-way flow of blood from distal to proximal leg. OBJECTIVE: To describe and illustrate the different deep veins, their relationship to each other, and to the superficial venous system. Of particular interest is the demonstration of the deep plantar plexus and its relationship to the anterior and posterior tibial veins and to the greater and lesser saphenous veins. The valvular system, which protects them from the effects of gravity, is also illustrated. METHODS: The various deep veins as well as their tributaries and perforating veins are described in detail and illustrated with simple line drawings. These depictions help clarify the relationships between the paired veins and the higher single veins. RESULTS: Hopefully this unified approach to the various groups of deep veins will allow a better understanding of their form and function. CONCLUSIONS: The deep venous system is an integrated group of veins beginning in the deep venous plexus of the foot and terminating in the lower pelvis. Following contraction of the foot, calf, and thigh muscles the blood flows from a multitude of high pressure veins to a single low pressure vein.
