and the ability to keep visceral vessels "in flow" whereas endografting requires a "seal-zone", replacing the "clamp position" of open surgery. Method:We propose division of the visceral segment into zones based on the location of this "seal-zone": -Zone 0: below the lowest renal artery -Zone I: between renal arteries -Zone II: between the upper renal artery and SMA -Zone III: between the SMA and CA -Zone IV: above the CA Results: We present our series of 61 complex EVAR based on this classification system.Mean operative time (hrs): Zone I/II (n¼20) 5.1, Zone III (n¼25) 6.9, Zone IV (n¼16) 8.6.Mean number of target vessels: Zone I/II 1.75, Zone III 2.9, Zone IV 3.5.Morbidity/mortality: zone I/II 35/0%, Zone III 48/16%, Zone IV 38/13%.Conclusions: Higher seal-zones reflect increasingly complex procedures and are associated with greater morbidity and mortality.The proposed seal-zone classification allows for accurate and reproducible differentiation between aneurysms requiring complex endovascular repair, replacing the surgical clamp-based classification.0780
