Radiographic complicated and uncomplicated descending aortic dissections: aortic morphological differences by CT angiography and risk factor analysis
Authors' conclusion
We identified significant morphological differences and predictors for adverse events in patients presenting complicated and uncomplicated descending dissections.
Study context
- Population
- Patients with acute descending aortic dissection, April 2009–July 2021
- Participants
- 209 patients
- Exposure
- Complicated vs uncomplicated acute descending aortic dissection
- Complicatedn = 74
- Uncomplicatedn = 135reference
- Outcome
- Early aortic failure:
- Reoperation
- Diameter progression
- Early mortality
Methodological detailsDetailed CTA measurements (slice thickness ≤ 3 mm) in multiplanar reconstruction
- Detailed CTA measurements (slice thickness ≤ 3 mm) in multiplanar reconstruction
