Chronic typeB aortic dissection-what to do?

Abstract

Chronic typeB aortic dissection requires optimal medical therapy. However, secondary complications like organ or extremity malperfusion or development of aneurysmal dilatation require interventional therapy. Presentation of different endovascular treatment options for complications of chronic typeB aortic dissection. Analysis of current literature with regard to indications, techniques, results, and differential indications of interventional techniques for the treatment of chronic typeB aortic dissection complications. Endovascular implantation of an aortic stent graft is interventional standard therapy for treatment of aneurysmal dilatation of the aorta following typeB dissection. Technical problems are the proximal and distal landing zones and the treatment of persistent flow in the false lumen. Endovascular treatment of chronic complicated typeB aortic dissection is increasingly used compared to open surgical treatment because not only are more complex stent grafts (fenestrated and branched devices) available but also because of newly developed techniques for effective occlusion of flow in the false lumen (e.g., candy plug).
