Which statement about radial access is correct?

• A. Radial access reduces groin complications and allows quicker ambulation.
• B. Radial access increases risk of groin hematoma.
• C. Radial access is not used for diagnostic procedures.
• D. Radial access always requires a surgical cut-down.

Answer: (A)

Access through the radial artery is favored because it significantly lowers bleeding and other groin-related complications and allows patients to ambulate sooner after the procedure. The groin (femoral) approach carries a higher risk of hematoma, pseudoaneurysm, and longer bed rest due to the larger vessel and deeper location, so using the radial artery in the arm generally means quicker recovery and less time immobilized.

Radial access is routinely used for diagnostic coronary angiography and many interventions, so it is not limited to any narrow set of procedures. It also does not require a surgical cut-down; the entry is obtained percutaneously with puncture and sheath placement, followed by manual or mechanical compression to achieve hemostasis at the wrist.

Be mindful that radial access has its own considerations, such as the potential for radial artery spasm or occlusion and the need to ensure adequate collateral hand circulation in some patients. It isn’t always possible in every patient, but when feasible it offers the advantage of reduced groin complications and earlier ambulation.
