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.
