Description
Yusuke Takei and nine colleagues reported in 2026 early-to-mid-term outcomes for zone 1 total arch replacement with a frozen elephant trunk in acute type A aortic dissection. The zone 1 approach moves the repair closer to the heart and adds a bypass to the left subclavian artery, aiming to balance safety against complexity.
Among 80 patients treated between 2014 and 2025, thirty-day mortality was 8.8 percent and in-hospital mortality 10.0 percent, with stroke in 12.5 percent and spinal cord injury in 5.0 percent. Freedom from aorta-related events fell to 81.5 percent at five years, while bypass-related freedom stayed higher. Most bypass events were silent blockages from technical issues. Bypass durability remains a concern, and careful follow-up matters for selected patients.
