To facilitate the accurate orientation of the surgical fields, we had developed a Multidimensional CT-based navigation system and clinically applied in thoracoabdominal aortic aneurysm repair with selective reconstruction of Adamkiewicz artery. Thirty patients who had thoracoabdominal aortic aneurysm were studied using Multidimensional CT imaging to identify their Adamkiewicz artery preoperatively. During navigation, the pointer location was measured by the sensor in the surgical field, and simultaneously, anatomical structures were visualized by the three-dimensional images. Then the position of the targeted intercostal arteries were successfully found in the real field, the targeted arteries and major visceral arteries were reconstructed. Hospital deaths were one patient and there was no paraplegia. A new navigation system was effective to improve an accurate orientation. Our clinical experiences exhibited that this system for thoracoabdominal aortic aneurysm repair provides a safe and effective surgery.
