Verschlüsse der Arteria radialis nach Herzkathetereingriffen – DGK-Stellungnahme
摘要
The transradial approach (TRA) is the preferred standard access for invasive coronary angiography and intervention, offering clear advantages in terms of mortality, bleeding complications, vascular safety and length of hospital stay. The European Society for Cardiology (ESC) guidelines 2023 and 2024 assign a class I‑A recommendation to TRA for acute or chronic coronary syndrome. The most frequent complication is radial artery occlusion (RAO), with a reported frequency of 5–15%. The RAO is usually asymptomatic, although about one third of patients experience mainly local discomfort. Severe impairment of hand perfusion is very rare and the incidence of clinically significant hand ischemia after TRA is below 0.1%. Key preventive measures include a meticulous puncture technique, adequate anticoagulation during the procedure, avoidance of arterial spasm and short nonocclusive hemostasis.Routine use of collateral tests such as the Allen test are unnecessary. The diagnostics of RAO should be reserved for clinically symptomatic patients. In selected cases medicinal, interventional or surgical treatment can be considered. The overarching aim is the sustainable preservation of the radial access as a safe, patient-friendly and safe standard access technique in interventional cardiology.
