大動脈に対するステントグラフト留置後の画像診断

抄録

For the treatment of aortic diseases, abdominal endovascular abdominal aortic pair (EVAR) and thoracic endovascular aortic repair (TEVAR) have been widely used. More than a half of abdominal aortic aneurysms are now treated with EVAR. Thoracic descending aortic aneurysm is treated with TEVAR as the first choice.
In recent years, stent-graft treatment has been approved for insurance purposes to aortic dissection and its adaptation has spread further.
Unlike surgical replacement, stent-graft is a treatment that leaves a pathologic aorta even after treatment,and secondary intervention is more frequent than after surgical replacement. Therefore, follow-up imaging is required over a long period of time, and the role of radiologists is also important.
This review provides imaging findings after stent-graft placement. We also describe criteria to evaluate endoleaks, re-interventions or surgical treatments.
