Key result
Aortic dissection sparing the ascending aorta was associated with better survival (42.1% survived 6-69 months) compared to ascending aorta involvement, where no patients survived beyond 3 weeks.
Observational (n=62)
No
Absolute Event Rate: 42.1% vs 0%
Aortic dissection involving the ascending aorta carries a dismal prognosis with no survival beyond 3 weeks, whereas distal dissections have better survival and distinct clinical features like marked systemic hypertension.
No takes yet. Share an insight, caveat, or question.
Underscores dismal prognosis with ascending involvement; leaves open whether modern care improves distal dissection survival.
Lindsay et al. (1967) conducted an observational in Aortic dissection (n=62). Dissection sparing the ascending aorta vs. Dissection involving the ascending aorta was evaluated on Survival. Aortic dissection sparing the ascending aorta was associated with better survival (42.1% survived 6-69 months) compared to ascending aorta involvement, where no patients survived beyond 3 weeks.
