Outcomes of thoracic endovascular repair for type B aortic dissection with multichanneled morphology

MCAD was identified in a small but not insignificant number of our patients presenting with type B AD. Urgent or elective TEVAR was indicated in all our patients with MCAD. In patients with MCAD, full TL collapse was associated with worse outcomes, and this finding may indicate the need for more urgent or emergent repair.
