Endovascular repair of the thoracic aorta: preoperative and postoperative evaluation with multidetector computed tomography.

Endovascular techniques have emerged as a minimally invasive alternative for the repair of the descending thoracic aorta, especially in high-risk patients. Multidetector computed tomography has a pivotal role, specifically in determining the candidacy or exclusion of patients for thoracic endovascular aortic repair and preoperative planning. In addition, multidetector computed tomography is used for follow-up assessment of the postsurgical aorta, so that potentially fatal complications can be correctly diagnosed and treated in a timely manner. In this pictorial review, we focus on the preoperative assessment of the pathologic aorta and evaluation after thoracic endovascular aortic repair.
