Chronic type B aortic dissection is a distinctive condition that needs individual treatment strategies and different considerations than in therapy of acute or subacute type B aortic dissection. The most common indication for treatment of this complex disease is aneurysmal dilatation of the dissected aortic segment. While open repair of the enlarged dissected aorta remains the best option for good-risk patients and patients with connective tissue disorders in high-volume centers with respective expertise, endovascular management of chronic type B aortic dissection with postdissection aneurysms has significantly gained ground in the past years. But the concept of TEVAR with implantation of a tubular stent-graft into the thoracic aorta to seal the proximal entry tear and reroute the blood flow into the true lumen alone, is not associated with satisfactory results. This is mainly due to the sparse remodeling capacity of the aortic tissue compared to earlier stages of the disease as the aortic wall and the dissection membrane are thickened and more rigid. On the other hand, it is restricted by the most limiting factor for endovascular success in chronic type B aortic dissection: persistent false lumen perfusion. This problem also affects patients with residual dissection after surgical repair of a DeBakey type I aortic dissection or dissection after ascending aortic repair for other pathologies. Hence, it is evident that strategies to achieve endovascular false lumen occlusion are of increasing importance and novel techniques have been introduced to solve the problem of persisting false lumen flow. Thus, the evolution of a large variety of techniques to address the false lumen perfusion issue indicates that complicated chronic type B dissection involves a high diversity in clinical presentation and morphology. A large armamentarium of catheter skills as well as critical individualized treatment strategies are required to address the heterogenous morphological disease pattern for each individual patient. The rapid development in endovascular techniques gives new directions for treatment indications and strategies in chronic aortic dissection and enables new insights into this old disease.
