This is the first textbook entirely dedicated to the endovascular treatment of complications related to arteriovenous accesses for hemodialysis (native fistulas and prosthetic grafts). The book addresses the anatomy of upper limb arteries and veins as well as the clinical presentation of patients and the way to perform and read a fistulogram. Many details and illustrations are provided, clarifying the subtleties in catheterization and the dilation of stenoses. From a strategic point of view, it is explained for the first time that many stenoses must either be ignored or deliberately underdilated. A wealth of images helps to understand the different stages of access recovery from thrombosis.
