Why the study?

Do acute-phase factors (maximum aortic diameter ≥40 mm and patent false lumen) predict chronic-phase aortic enlargement in patients with uncomplicated type B acute aortic dissection?

101 patients with type B acute aortic dissection who had no complications during the acute phase

Comparison

Maximum aortic diameter of ≥40 mm and a patent… vs Maximum aortic diameter of <40 mm and a closed…

Overview

High-risk features stratify enlargement risk in uncomplicated type B dissection; leaves open whether early intervention improves outcomes.

Structured PICO

Do acute-phase factors (maximum aortic diameter ≥40 mm and patent false lumen) predict chronic-phase aortic enlargement in patients with uncomplicated type B acute aortic dissection?

P
Population
101 patients with type B acute aortic dissection who had no complications during the acute phase
I
Intervention
Maximum aortic diameter of ≥40 mm and a patent false lumen during the acute phase (as risk predictors)
C
Comparator
Maximum aortic diameter of <40 mm and a closed false lumen
O
Outcome
Chronic-phase enlargement (≥60 mm) of the dissected aortasurrogate

Patients with uncomplicated type B acute aortic dissection who have a maximum aortic diameter ≥40 mm and a patent false lumen are at high risk for chronic-phase aortic enlargement and may benefit from earlier surgical intervention.
