May warrant closer oxygenation monitoring in extensive distal AAD; leaves open causal mechanisms and targeted interventions.

The extent of aortic injury in acute aortic dissection is independently associated with the development of oxygenation impairment, likely mediated by systemic inflammation.
Kurabayashi et al. (2010) conducted an observational in Acute aortic dissection (n=49). Extent of acute aortic dissection (AAD%) vs. Lower extent of acute aortic dissection was evaluated on Oxygenation impairment (PaO2/FiO2 ratio ≤200) (OR 1.323, 95% CI 1.035-1.691, p=0.026). The extent of distal acute aortic dissection (AAD%) was an independent predictor of oxygenation impairment, with an odds ratio of 1.323.
