Dissection of Arch Branches Alone: An Indication for Aggressive Arch Management in Type A Dissection?

ABSTRACT:

Background

It is controversial if extension of aortic dissection into arch branches should be an indication for replacement of the arch and its branches in acute type A aortic dissection.

Methods

From 2008 to April 2018, 399 patients underwent open repair for an acute type A aortic dissection, and 190 patients had known innominate and/or left common carotid artery dissection without malperfusion syndrome, including no arch procedure (n = 1)/hemiarch replacement (n = 109) and zone 1/2/3 arch replacement (n = 80) with replacement of 1 to 4 arch branch vessels.

Results

Median patient age was 58 years. Preoperative comorbidities were similar between groups, except the hemiarch group had more coronary artery disease (22% vs 3%, P = .0002). Both groups underwent similar aor
