[A case report of the preoperative diagnosis of thoracoabdominal aortic aneurysm by three-dimensional CT angiography].

A sixty-year-old woman with the thoracoabdominal aortic aneurysm (7 cm in the diameter) was evaluated by the newly developed three-dimensional CT angiography. The thoracoabdominal aortic aneurysm was scanned by spiral CT and three-dimensional images were generated preoperatively. The three-dimensional structures of the thoracoabdominal aorta with the aneurysm, the celiac trunk and the superior mesenteric artery were clearly visualized by this method. The thoracoabdominal aorta was replaced by the graft with the reconstruction of celiac trunk. The post-operative course was uneventful. The preoperative diagnosis of thoracoabdominal aortic aneurysm by this method was very useful in the determination of operative procedure in this case. Three-dimensional CT angiography may be the useful method in the preoperative diagnosis of the aortic surgery.
