Abstract
Endovascular repair (EVAR) for abdominal aortic aneurysms (AAAs) is becoming the standard of practice in most vascular centers, even if some concerns remain about the occurrence of early and long-term failure and reintervention. A rare but potential catastrophic event is represented by retrograde type B aortic dissection (RTBAD). We report 2 cases of RTBAD after 425 standard EVARs performed in our institution. Both patients were treated for AAA without perioperative complication, and in both the patients, the presence of a preexisting disease of the thoracic aortic wall (ulcerated plaque in 1 case and aortic ectasia in the other) may have played an important role in the rapid evolution toward an early onset of the dissection. Only few cases of type B dissection after EVAR have been reported in literature, and the etiology of this complication remains uncertain. For the first time, our experience highlights the possible etiologic role of preexisting lesions of the thoracic aorta. In these cases, the only possible strategy may be to carefully study the entire aorta before an EVAR procedure, eventually switching the indication to an open surgical repair or carrying out a more aggressive management, treating the defects of the thoracic aorta.
