Management of Aortic Dissection----New classification and Mid-term results

Division of Cardiovascular Surgery Xijing Hospital, Xi’an, China

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

Zone 4

Zone 3

Zone 4


Materials and Methods Mid-term results

  • From December 2001 to June 2009

  • 525 patients (492 male, 33 female)

  • The average age of 49.2 years old (37 ~ 73)

  • Acute dissection 491

  • Chronic dissection 34


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.)



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.



Results tears in Zone 4

Mortality Rate

  • Procedure related

    Complications

  • Heart failure

  • Renal failure

  • Cerebral insufficiency

  • Infection

  • Endoleak

  • Hepatic insufficiency

  • Iatrogenic dissection

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
