[Patch Repair by Anterolateral Thoracotomy with Partial Sternotomy for Saccular Aortic Arch Aneurysm with Severe Thoracic Deformity:Report of a Case].

An 87-year-old male was referred to our hospital for surgery of saccular aortic arch aneurysm. As he had a history of thoracoplasty on his left side due to pulmonary tuberculosis, his aortic arch adhered to the apex of the left thorax. Total arch replacement(TAR) via median sternotomy was considered difficult, and anterolateral thoracotomy with partial sternotomy (ALPS) was performed. During surgery, we considered TAR difficult even with ALPS approach. Taking account of his age, aneurysmectomy and patch repair were chosen instead of TAR to shorten operation time. Although he suffered from diffuse cerebral infarction, he was discharged without neurological deficit at 39 days after operation.
