Endovascular treatment is increasingly being applied to aortic pathology. Chronic type B aortic dissection complicated by aneurysmal dilatation is pathology where endovascular graft deployment appears to offer a logical and low morbidity therapeutic solution. Reports confirm a high level of primary technical success and a low incidence of complications in fit patients following thoracic endovascular aortic repair (TEVAR). In chronic aortic dissection there is limited potential for inducing aortic remodeling. Stent-graft deployment can induce false lumen thrombosis, reducing the risk of disease progression and subsequent aneurysm rupture. Although there is currently no long-term evidence, this data will become available as the stent-graft registries mature. This review presents the current evidence for TEVAR in the management of chronic type B aortic dissection in “fit for surgery” patients. It discusses the natural history of the disease, goals and methodology of treatment and compares outcomes with established open surgical procedures.
