Current Status
Distal radial access (DRA) has rapidly gained acceptance as a novel vascular access option in interventional cardiovascular medicine. Rapidly, DRA has evolved to address the complications of forearm radial artery occlusion following catheterization. This innovative approach has quickly demonstrated significant advantages over conventional transradial access (TRA). Indeed, DRA is associated with a lower rate of radial artery occlusion, faster and easier hemostasis, and reduced access-related bleeding. These benefits have been progressively demonstrated in multiple registries and trials and have recently been validated by meta-analyses. In addition, the versatility of DRA extends beyond interventional cardiology and radiology to a wide range of percutaneous vascular procedures. Despite its significant advantages, DRA faces some challenges, including a steeper learning curve, higher failure rates, and an increased need for puncture attempts. However, there is considerable potential to improve success with specialized materials and ultrasound-guided puncture. Overall, DRA represents an important evolution in vascular access, offering improved patient outcomes and efficiency. This chapter underscores the transition from conventional TRA to DRA and highlights the adaptability and efficacy of the technique in modern medical practice.
