Operative Cases of the Distal Aortic Arch Aneurysm through Median Sternotomy / 日本心臓血管外科学会雑誌

ABSTRACT

Seven patients underwent surgical repair of the distal aortic arch aneurysm from January 1990 to October 1997. They were 5 men and 2 women ranging from 63 to 78 years of age (mean, 72.7 years). All patients were operated with a median sternotomy only. There was one operative death, which was ruptured case. However, there were no major complications in non-ruptured cases. This retrospective study suggests that it is possible to repair the distal aortic arch aneurysm through a median sternotomy approach alone, when 1) descending aorta originates with normal size just distal to sacciform aneurysm, 2) the maximum diameter of the aneurysm is over 70mm and 3) distal involvement of the aneurysm does not extend beyond the bifurcation of the trachea. It is useful to retract descending aorta proximally by three threads with pledget for distal anastomosis in inclusion technique.
