Minimally invasive surgical operations are the surgical procedures, which limit the size of incisions required. Consequently, they reduce the risk of infections, pain and wound healing time. Angioplasty and endovascular aneurysm repair are some examples. Such surgeries are guided by tracked surgical instruments in addition to preoperative or intraoperative images. Using cameras, ultrasonic and electromagnetic fields or a combination of these, the patient’s anatomy and the surgeon’s precise movements are captured and relayed in real-time. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of minimally invasive surgical operations. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. As this field is emerging at a fast pace, this book will help the readers to better understand the concepts of minimally invasive surgical operations.
