Key result
Emergency endovascular stent-grafting yields 6-month false lumen obliteration and carotid recanalization in retrograde ATAAD.

Does emergency endovascular repair improve outcomes in a patient with retrograde type A aortic dissection with malperfusion?
Emergency endovascular repair with a stent-graft successfully treated retrograde acute type A aortic dissection with malperfusion in an elderly patient.
Hypothesis-generating for emergency endovascular repair in retrograde type A dissection with malperfusion; requires validation in prospective studies.
An 81-year-old man became semiconscious and suffered back pain followed by chest pain. Computed tomography showed retrograde acute type A aortic dissection with entries in the proximal and middle descending aorta, and an occluded true lumen of the right carotid artery. Emergency endovascular repair was performed. Immediately after deploying a stent-graft, aortography showed recanalization of the right carotid artery and no blood flow in the false lumen of the ascending aorta and aortic arch. The postoperative course was uneventful. Computed tomography at 6 months after the procedure showed obliteration of the false lumen and a patent right carotid artery.

Takahashi et al. (2014) conducted a case report in Retrograde acute type A aortic dissection with malperfusion (n=1). Emergency endovascular repair (stent-graft) was evaluated on Postoperative course and CT findings at 6 months. Emergency endovascular repair using a stent-graft in an 81-year-old man with retrograde acute type A aortic dissection resulted in recanalization of the right carotid artery and obliteration of the false lumen at 6 months.
