Background:
The simultaneous surgical treatment of thoracic aortic arch aneurysm (TAA) and lung carcinoma is extremely rare.
Case Presentation:
We report the simultaneous surgical treatment of TAA and squamous cell carcinoma of the lung in a 72-year-old Japanese man. We performed a one-stage operation that consisted of aortic arch replacement for aortic arch aneurysm with a 3-branched artificial vessel under separate cerebral and systemic extracorporeal circulation, and left upper lobectomy for lung cancer via a left lateral thoracotomy.
Conclusions:
Although patients should be carefully selected for this procedure, the simultaneous surgical treatment of TAA and lung carcinoma can be performed safely.
