Renal Artery Orientation Influences the Renal Outcome in Endovascular Thoraco-abdominal Aortic Aneurysm Repair

Renal artery orientation significantly affects the early RA outcome of FB-EVAR for TAAA. Intra-operative RA loss is predicted by type B RA orientation and branches, while early RA occlusion is predicted by type D orientation and branches. The present data suggest that in TAAA, fenestrations should be the first choice for renal revascularisation in type B and D RA orientations.
