Comparison of outcomes for short-neck and juxtarenal aortic aneurysms treated with the Nellix endograft versus conventional endovascular aneurysm sealing

The off-label use of the Nellix endograft for the treatment of JAA showed a higher rate of subsequent conversion to open repair for JAA patients (aortic neck length ≤4 mm), underlining the need for a proximal sealing zone. Longer term data are needed to verify the possible use of the Nellix endograft in selected short-neck aneurysms with aortic neck length >5 mm.
