The advent of endovascular prostheses to treat descending thoracic aortic lesions offers an alternative approach in patients who are poor candidates for surgery. We present a case of a type B descending thoracic aortic dissection with rapid aneurysmal evolution in a woman with a giant-cell arteritis, treated by endovascular repair: 26 months after, we observed the anterior dislocation of the distal segment of the stent. The dislocation required a second treatment in order to avoid the aortic wall rupture and to restore the axis of the prosthesis. This report emphasizes the difficulty of the endovascular repair in the giant-cell arteritis, because of the vascular fragility confirmed by the rapid aneurysmal evolution after the type B dissection and the appearance of the stenting complication.

Key Words: Endovascular repair; Giant-cell arteritis; Stent dislocation
