What is the most common arterial puncture site for angiography procedures?

The common femoral artery is the most frequently used puncture site for angiography procedures due to several factors. It provides excellent access to the arterial system for both diagnostic and interventional procedures. The anatomical location of the common femoral artery is readily palpable and accessible in most patients, making it an ideal site for catheterization.

Additionally, performing procedures through the common femoral artery allows for larger catheters to be used, which is beneficial for certain interventions. It also has a relatively high flow rate and can accommodate larger bore sheaths for various angiographic techniques. Lastly, the potential complications related to access at this site are well understood, and protocols have been established to mitigate risks effectively.

In contrast, while the radial artery has gained popularity due to its lower complication rates and easier patient recovery, it is not as commonly used as the primary access site for angiography compared to the common femoral artery, especially in complex procedures. The subclavian artery is primarily used for specific scenarios requiring upper extremity access and may not be suitable for all angiographic needs. The popliteal artery is less frequently employed as a puncture site since it is located deeper and has a greater risk of complications, particularly related to access.
