[A case report of thoracic aortic aneurysm associated with tubular hypoplasia].

A 55-year-old female was diagnosed as thoracic aortic aneurysm associated with tubular hypoplasia. A saccular aneurysm occupied the aortic arch between left common carotid and left subclavian arteries, arising from the cranial wall of the tubular hypoplasia. The aneurysmectomy was performed under cardiopulmonary bypass with selective cerebral perfusion and woven Dacron graft was implanted. The post-operative course was uneventful and she was discharged 32 days after the operation. Aneurysm associated with coarctation usually is thin walled, therefore an early surgical treatment should be urged.
