Abstract
Thoracic endovascular aortic repair (TEVAR) is particularly indicated in a patient with complicated type B dissection. The object of this communication is to report a case of deployment of the endograft in the false lumen, to propose a protocol in order to prevent it and discuss the possible surgical options when this complication has occurred. A case of complicated acute type B dissection is described where the endovascular prosthesis was positioned in the false lumen. The literature on the subject is briefly reviewed for the insertion techniques and conversion to surgery. The occurrence was recognized and treated with replacement of the entire aorta from the sinotubular junction to a level of the eighth thoracic vertebra under deep circulatory arrest with selective antegrade cerebral perfusion. TEVAR for complicated type B dissection should be carried out according to a precise and stepwise protocol in institutions familiar with all the different options of conversion to open repair.
