We report a case of chronic localized thoracoabdominal aortic dissection with an entry located just above the celiac artery which was successfully treated by patch aortoplasty. The patient was a 55-year-old man who complained of abdominal and back pain. CT scan and angiography showed a localized thoracoabdominal aortic dissection the entry of which was located just above the celiac artery. The patient underwent resection of the aneurysm and patch aortoplasty with the aid of a femoro-femoral bypass. The postoperative course was uneventful. Localized thoracoabdominal aortic dissection has been reported in only 5 cases, including our case, in the Japanese literature.
