[Two cases of stent graft repair for thoracic aortic dissection: usefulness of three-dimensional computed tomogram].
We carried out stent graft repair in two patients with Stanford type B thoracic aortic dissection. A 51-year-old male was admitted to our hospital because of thoracic aortic dissection. Chest CT revealed an aneurysm of the distal aortic arch. The entry was pointed out 1 cm distal from the take off of the left subclavian artery in three-dimensional CT (3 D-CT). He was treated with a Gianturco stent which was anchored into the 30 mm Hemashield graft under selective cerebral perfusion. Another case was a 72-year-old male with a descending aortic aneurysm. 3 D-CT showed that the entry existed 4 cm proximal to the celiac artery. We performed transluminal implantation of the spiral Z-stent covered with the woven Dacron graft. 3 D-CT was useful for the preoperative management and the surgical treatment of thoracic aortic dissection.
