What is the arterial puncture angle for the femoral site?

Explanation:
Accessing the femoral artery is best done with the needle directed straight in toward the vessel, essentially a perpendicular angle to the skin. The femoral artery sits relatively deep under the groin and runs more or less vertically, so a 90-degree approach increases the likelihood of entering the lumen on the first attempt by piercing the anterior wall cleanly. A steeper, near-perpendicular angle also minimizes the chance of skimming along the vessel wall or advancing too far, which could risk injury to posterior structures. In contrast, arteries that are more superficial, like the radial, are commonly cannulated with a shallower angle (around 30-45 degrees) because they are closer to the skin surface. So for the femoral site, the appropriate puncture angle is about 90 degrees.
