Successful endovascular correction of an endograft connected with the false lumen of a type B aortic dissection.

Thoracic endografting is widely used in the treatment of complicated acute type B aortic dissections to redirect the entire aortic flow toward the true lumen by covering the proximal entry tear. This procedure is challenging because endovascular navigation, maintaining position in the true lumen, can be difficult as there are frequently numerous reentry tears. There is obvious potential for complications such as malpositioning of the distal part of the endograft within the false lumen. This error can promote true lumen collapse and/or aortic rupture. This report details the endovascular correction of such a complication.
