Management of Aortic Dissection----New classification and Mid-term results
Dinghua Yi, et al
Zones based on hybrid procedure Mid-term results
Criado Zonation， 2005 (According to stent graft, suitable for aneurysm)
Xijing Classification, 2006 （According to primary tear, suitable for dissection ）
Zone 1 Mid-term results
Materials and Methods Mid-term results
For dissection with primary tears in Zone 1 (+2,3,4), open surgery remains the gold standard (including Bentall, total arch replacement, concomitant CABG etc.)
Frozen elephant trunk technique was applied in patients with multiple tears (Zone 1 +Zone 2,3,4)
Ascending aorta to bilateral common carotid artery bypass should be established before endovascular exclusion for primary tears in Zone 2.
Bilateral common carotid artery bypass should be established before endovascular exclusion for primary tears located in the Zone 3.
TEVAR became the gold standard for dissection with primary tears in Zone 4
Results tears in Zone 4
Discussion tears in Zone 4
Defining zones according to the tear location is useful for planning a hybrid approach
Zone 2：Ascending aorta Bypass +TEVAR
Zone 3：Carotid Bypass+TEVAR
Zone 1：Ascending Aorta Replacement
Zone 4: TEVAR
