Patterns of superficial veins of the cubital fossa in Malays.

Patterns of superficial veins of the cubital fossa were studied in 170 male and 96 female Malays. Six venous patterns were observed. The less commonly known but clinically important patterns observed included absence of communication between basilic and cephalic veins (in 7.3% females and 8.8% males); an arched median cubital vein (in 2.0% females and 6.5% males); absence of the cephalic vein (in 1.0% females and 2.9% males) and two median cubital veins (in 1 male only). Awareness of these uncommon cubital venous patterns and their approximate incidence would be very useful for those performing venepuncture or venesection in Malays, especially under emergency conditions.
