Hybrid Technique to Correct Cerebral Malperfusion following Repair of a Type A Aortic Dissection

A 49-year-old man with drowsy mentality was diagnosed with acute type A
aortic dissection; he underwent an emergency operation. When selective
antegrade cerebral perfusion
was initiated, the right regional cerebral oxygen saturation (rSO2)
decreased as compared to the left one. Adequate blood flow was perfused
through the branch of the artificial graft, after distal anastomosis,
but the right rSO2 did not recover. Angiography revealed another intimal
tear on the right common carotid artery. A stent was then inserted. The
right rSO2 promptly increased to the same level as that of the left
one. The patient was discharged without any neurologic complications.
