[A case of type A acute aortic dissection successfully treated with a ringed intraluminal graft: a new technique of...

A-77-year old woman was hospitalized at our hospital presenting with severe chest and back pain. A computed tomographic scan revealed acute type A aortic dissection and intraoperative ultrasound showed an entry near the brachiocephalic artery. Selective cerebral perfusion using flexible 12 Fr balloons was performed for brain protection. The distal aorta was trimmed just proximal to the entry using felt strips and a 24 mm ringed intraluminal graft (ILG) was inserted under it successfully. The patient did well after the operation. Insertion of a ringed ILG is a simple and easy technique, however if an entry is located near the aortic arch, insertion is difficult because of intimal retraction to the arch. And an additional intimal tear sometimes occurs at the site of tape ligation. The method which we presented seemed to provide safer insertion of the proximal ring without these problems.
