This book provides an elucidative account on the applications of arteriovenous fistulas. They are shunts between arteries and veins that can be seen in several organs of the human body like the brain, skin, eye and lung. They have a potential to be symptomatic by causing ischemia, using the process of steal phenomenon, or vascular congestion and consequent hemorrhage; for instance, intracerebral hemorrhage of a ruptured dural arteriovenous fistula. The etiology of these lesions is not completely understood. While some of these are congenital; others are acquired. Additionally, iatrogenic arteriovenous fistulas can be lifesaving in many cases, like in hemodialysis patients. This book offers a vivid and concise outlook on the diagnosis and management of arteriovenous fistulas all over the human body. It should be a valuable resource for medical students, residents, fellows, professors and researchers involved in this field.
