What are common radial access complications and their management?

• A. Spasm (vasodilators), hematoma (compression and monitoring), and rare radial artery occlusion (patent by ensuring proper technique)
• B. Infection, thrombosis, and anaphylaxis
• C. Pulmonary embolism, stroke, myocardial infarction
• D. Nerve injury, skin necrosis, edema

Answer: (A)

Radial access complications are mainly local to the access site, and the three most common issues are radial artery spasm, a hematoma at the puncture site, and radial artery occlusion, which is rare but important to prevent. Spasm happens when the artery constricts in response to catheter manipulation. It is best managed with vasodilators given intra-arterially, such as nitroglycerin or calcium channel blockers, to relax the vessel and ease catheter advancement. A hematoma forms from bleeding into the soft tissue around the puncture site. The key management is prompt compression to stop the bleed and careful monitoring to ensure it does not expand, while maintaining overall patient stability. Radial artery occlusion is uncommon but can hinder future radial access. Prevention centers on proper technique: using the smallest feasible sheath, adequate anticoagulation during the procedure, and achieving patent hemostasis during closure (compressing just enough to stop bleeding while allowing some arterial flow). This reduces the chance of a clot forming in the artery and helps preserve access for future procedures. The other listed problems—systemic events like infection, thrombosis leading to distant complications, or anaphylaxis, and nerve injury or skin issues—can occur but are not the typical trio seen with routine transradial access, and their management focuses on different mechanisms.
