This is the first book devoted entirely to distal radial access, a novel vascular access technique that has become a major topic of interest in interventional cardiology, interventional radiology and neurointervention. The rapid spread of distal radial access through social media has been remarkable, reflecting the wide curiosity surrounding this approach. While almost every interventionalist is aware of it, many have yet to fully grasp its clinical significance and the nuances of its proper implementation. Given its growing importance, this topic warrants a more structured, rigorous and comprehensive discussion. This volume aims to elucidate the scientific basis of distal radial access and provide a thorough critical review of the existing literature. Each chapter focuses on a different aspect of the technique and is written by leading experts from different institutions, ensuring a diverse perspective that enriches the content. With its commitment to scientific excellence, this book serves as the most comprehensive and up-to-date reference on distal radial access, written by the very pioneers who have contributed to its development and evaluation. It is intended primarily for interventional cardiologists, interventional radiologists, and neurointerventionalists who wish to improve their understanding and clinical practice in this evolving field.
