Usefulness of routine use of bilateral axillary artery perfusion in total arch replacement.

OBJECTIVES

To avoid cerebral infarction for aortic arch aneurysm and malperfusion for acute aortic dissection, the site of cannulation during total arch replacement remains important. Recently, we have used bilateral axillary artery perfusion in total arch replacement and in acute aortic dissection. Herein, we report the surgical outcomes.

METHODS

Seventy-eight patients with aortic arch aneurysm and 45 patients with acute aortic dissection were enrolled in this study. During surgery, translocation of the total arch was performed on 67 patients using a 'frozen elephant trunk technique'.

RESULTS

In patients with aortic arch aneurysm, there was no postoperative cerebral infarction. New postoperative cerebral infarction was observed in only one patient who underwent acute aortic dissection. Two patients who had aortic arch aneurysm and 2 patients who had acute aortic dissection died at the hospital. Complications related to bilateral axillary perfusion were not observed.

CONCLUSIONS

The routine use of bilateral axillary artery perfusion in total arch replacement for aortic arch aneurysm to avoid cerebral infarction has the potential to be a useful procedure. It can facilitate the frozen elephant trunk procedure in acute aortic dissection.
