Thoracoabdominal aortic aneurysm (TAAA) is a complicated aortic disease. Most treatments for other aortic aneurysms have already shifted from conventional open surgery to endovascular operation; but for TAAA, open surgery remains the gold standard treatment. Several alternative treatments such as hybrid operation as well as endovascular techniques are utilized for the treatment of TAAA. Some of the procedures combine off-the-shelf devices such as the chimney procedure. Some other procedures required custom-made specialized stent grafts. A new off-the-shelf multi-branched endograft, T-branch graft, was released in late 2012, though it was not introduced into Taiwan until 2015. Ultimately, also we plan to report the experience of multi-branched endograft in Taiwan.
