[A case of extra-anatomic bypass for ruptured thoracoabdominal aortic aneurysm with tuberculosis]

Now aneurysmectomy and graft replacement is the most popular surgical method of aortic aneurysm, but there are many opinions about surgical methods and assist circulation for emergency operation of ruptured aortic aneurysm. We experienced the case of ruptured thoracoabdominal aortic aneurysm with tuberculosis, and rescued the patient by extra-anatomic bypass (EAB). A 60-year-old woman, who had been treated with tuberculosis for about 40 years, was operated on for cold abscess of her left psoas muscle by other orthopedic surgeons. At that time, massive bleeding happened, and she was transferred to us under diagnosis of ruptured thoracoabdominal aortic aneurysm. EAB, as emergency operation, was done because we considered it was dirty and dangerous to replace the prosthesis beside the abscess. The postoperative course was almost uneventful except the evidence of Gaffky's first stage. We considered EAB was an useful method for emergency cases and some infectious aortic aneurysms.
