ABSTRACT: We could observe the endoluminal stent graft (SG) following thoracic endovascular aneurysm repair
(TEVAR) by a coronary artery angioscope and establish intravascular visualization of SG. The
patient was a 70-year-old woman with the distal aortic arch aneurysm and the descending aortic
aneurysm, and debranching TEVAR were performed. After 12 months follow up, urgent hospitalization
was required for chest pain, and cardiac catheter examination with a coronary artery angioscope
was performed. The endoluminal SG was observed. The observation in angioscope which
is a video image is better than CT that is a still image, and observation in blood vessel or SG is
possible. It may be possible to observe the endoluminal SG, allowing potential investigation of an
endoleak, or the covering status of the SG with the native aortic vessel wall, or the state of intimal
membrane formation in the endoluminal graft.
