Key result
Open anastomosis with circulatory arrest for acute type A aortic dissection repair resulted in a 30-day mortality of 16.9% compared to 9.8% for closed anastomosis, with similar long-term survival.
Why the study?
Does open anastomosis with circulatory arrest compared to closed anastomosis without circulatory arrest improve survival in patients undergoing acute type A aortic dissection repair?
Cohort (n=100)
Does open anastomosis with circulatory arrest compared to closed anastomosis without circulatory arrest improve survival in patients undergoing acute type A aortic dissection repair?
Absolute Event Rate: 16.9% vs 9.8%
In patients undergoing acute type A aortic dissection repair, there was no significant difference in survival or postoperative complications between open anastomosis with circulatory arrest and closed anastomosis without circulatory arrest.
No takes yet. Share an insight, caveat, or question.
Open anastomosis was associated with higher early mortality; leaves open optimal technique pending randomized data in acute type A repair.
Vohra et al. (2012) conducted a cohort in Acute type A aortic dissection (n=100). Open anastomosis (circulatory arrest) vs. Closed anastomosis (no circulatory arrest) was evaluated on 30-day mortality. Open anastomosis with circulatory arrest for acute type A aortic dissection repair resulted in a 30-day mortality of 16.9% compared to 9.8% for closed anastomosis, with similar long-term survival.
