Management of acute type B aortic dissections

Abstract

This review will detail the etiology, classification, diagnosis and evolution in treatment of acute type B dissections. We will also review data from recent trials on thoracic endovascular aortic repair and its role in the management of type B aortic dissections to help determine which patients may benefit from placement of a stent graft. Expert commentary: As we see new technologies develop and obtain long-term results with TEVAR, the paradigm of management may shift toward a more aggressive operative approach to improve on the longterm mortality of patients with type B aortic dissections.

Intravascular ultrasound assisted sizing in thoracic endovascular aortic repair improves aortic remodeling in Type B aortic dissection

“…As TEVAR gains increasing significance, its optimal application is the key to the successful treatment of Type B aortic dissection by covering the proximal entry tear. The correct size and placement of the aortic stent graft has strong effects on remodeling, re-intervention rate, and subsequent outcome of patients [ 5 – 7 ]. Computed tomography (CT) is still the state-of-the-art technique for diagnosis and the planning of further treatment in most aortic diseases, which is at least partly due to its widespread availability.…”
