Comparison of extended arch vs hemiarch replacement in elderly patients with type A aortic dissection: the Shizuoka Kokuho Database.

Key Points

• To compare the outcomes of extended arch replacement (EAR) and hemiarch replacement (HAR) in elderly patients with type A aortic dissection (AAD).
• Analysis of data from the Shizuoka Kokuho Database.
• Assessment of postoperative mortality rates between the EAR and HAR groups.
• Comparison of reoperation incidence for bleeding.
• No statistically significant difference in postoperative mortality between EAR and HAR.
• Higher incidence of reoperation for bleeding observed in the EAR group.
