To report a pitfall encountered during stenting of a complicated penetrating ulcer of the descending thoracic aorta. ⋯ Endoprostheses may present some drawbacks in terms of elasticity and adaptability to tortuous and angulated diseased aortas. Caution is advised in the treatment of penetrating aortic ulcers where the aortic wall is diffusely friable. In this condition, balloon dilation should be limited to the covered portion of the stent-graft to prevent stent distortion and erosion through the aortic wall.
