transradialne

Transradialne is an adjective used in some languages to describe techniques, devices, or procedures conducted through the radial artery, most commonly in interventional cardiology and radiology. In English, the corresponding term is transradial, referring to transradial access for cardiac catheterization and related interventions. The concept centers on obtaining arterial access via the radial artery at the wrist, then advancing catheters to the heart or other vascular beds.

Medical applications include diagnostic coronary angiography, percutaneous coronary intervention, and peripheral or neurovascular endovascular procedures performed via the radial approach. Before access, clinicians may assess ulnar and radial circulation using the Allen test or Barbeau test. After puncture, a thin-walled sheath is placed, and standard catheterizations are performed with fluoroscopic guidance. Hemostasis after the procedure is typically achieved with compression devices or manual pressure.

Advantages of transradial approaches include a lower risk of major access-site bleeding, earlier patient mobilization, reduced need for bed rest, and greater patient comfort, contributing to shorter hospital stays in many cases. Common challenges include radial artery spasm, small vessel diameter, anatomical variations, and occasional radial artery occlusion. The technique requires operator familiarity and appropriate equipment, including catheters compatible with the radial route.

Transradial access was popularized in the 1990s, notably by Dutch interventionalist Jan Kiemeneij, and has since become a standard option in many centers worldwide, though femoral access remains appropriate in certain situations.
