Relationship between false lumen morphology and entry tear in acute type A aortic dissection.

Oh, look at us, we’ve been playing detective with aortic dissections! We’ve been rummaging through the records of patients who had emergency operations for acute type A aortic dissection between April 2011 and May 2022. We were particularly interested in the size, location, and position of the entry tear and pre-operative computed tomography findings.
We managed to confirm the characteristics of the entry tear in 134 out of 243 cases. The average age was 70.9 years, and 45.5% were male. We found that tear sizes at different aortic segments were not significantly different. But, oh boy, the tears posterior to the lesser curvature (PL) were significantly smaller than those anterior to the greater curvature.
And here’s the kicker: a thrombosed false lumen was associated with a significantly smaller tear size and position on the PL side in aortic cross-section. Our multivariate analysis showed that tear size, the presence of re-entry, and tear position anterior to the greater curvature were independent predictors of a patent false lumen.
So, in acute type A aortic dissection, larger tear size, the presence of re-entry, and tear position anterior to the greater curvature are risk factors for a patent false lumen. But remember, folks, these results are only valid for patients in whom intimal tears were detected during aortic surgery. Still, it’s a trend that may provide information for the pathophysiology of the disease. So, we’ve got that going for us, which is nice.
