[Intraoperative recanalization of type A chronic aortic dissection with a thrombosed false lumen]

A woman of 75 years old urgently admitted to our hospital for type A acute aortic dissection with a thrombosed false lumen, which had ulcer like projection (ULP) on enhanced computed tomography (CT) in the ascending aorta Aortic recanalization occurred in the operating room along with the establishment of extra corporeal circulation. Right axillar arterial perfusion directly struck the intimal tear site equaled to ULP, which caused intraoperative aortic recanalization. Graft replacement of the ascending aorta was successfully performed with the aid of hypothermic circulatory arrest and selective cerebral perfusion.
