Ultrasound-Guided Technique in Distal Radial Artery Catheterization Study

This study employs a modified ultrasound-guided dynamic needle tip positioning technique for distal radial arterial cannulation. The technique uses an ultrasound probe with two wires to create an acoustic shadow, improving needle tip visibility. Real-time dynamic tracking assists in precise needle placement within the distal radial artery through the nose-horn region. This method is used for coronary angiography and potential percutaneous coronary interventions, aiming to increase success rates and reduce complications like hematoma, nerve injury, and arterial spasm, thus enhancing safety and efficiency.
