- -antecubital fossa: shallow depression in front of the elbow
- 1) median cubital vein: H-shaped pattern, closer to the surface, typically larger, better anchored, and more stationary
2) Cephalic vein: lateral (toward the outer side of the body). H-shaped pattern. Harder to palpate, fairly well anchored, often the only vein that can be felt in obese patients.
3) Basilic: medial (toward the center of the body in supine position). venous distribution pattern. easy to palpate but not as well anchored and rolls more easily (increasing possible puncture to medial cutaneous nerve
or branchial artery
which underly this area).
