[A successful surgical case of DeBakey IIIb dissecting aortic aneurysm in association with right aortic arch].
A case of chronic DeBakey IIIb dissecting aneurysm in association with right aortic arch is reported. A 49-year-old man having encountered an aortic dissecting episode two years ago, was examined more closely because the aneurysm became larger recently. Digital subtraction angiography (intra-venous and intra-aortic) showed DeBakey IIIb dissecting aneurysm associated with a right aortic arch with aberrant subclavian artery. The entry of the aneurysm was in the right descending aorta passing from left thorax to right. The operative indication was for enlarged false lumen in this case. Graft replacement of the aneurysm and closure of the false lumen in the right thorax was performed under partial cardiopulmonary bypass through right thoracotomy. Postoperative digital subtraction angiography showed that dissection was in the abdominal aorta but false lumen in the thorax was completely closed. The patient has made a comeback working. A case of dissecting aortic aneurysm associated with right aortic arch is extremely rare. To our knowledge, this is the third such case reported in Japan, but the first case of a successful graft replacement for dissecting aortic aneurysm associated with right aortic arch.
