Different enclograft configurations (fenestrated, transrenal, infrarenal) may varyingly affect aortic side branch movement. Renal artery motion was evaluated with 64-slice dynamic cine-computed tomography angiography before and after endovascular aneurysm repair in 16 patients (46 renal arteries). Center-of- mass displacement of the renals was determined per heartbeat for before repair for 3 different endografts; differences were compared, with significance at P < 0.5. Preoperative renal artery motion is significant (1.2 [SI) 0.5] mm, range, 0.6-2.). Neither transrenal nor infrarenal enclografts alter renal artery motion com- pared with before repair (P < .05). Renal artery motion after fenestratecl endovascular repair with renal stents reduces motion to 25% of the preoperative value (0.3 [SD, 0.1] mm, range, 0.2-0.5 mm; P = .01). Enclograft implantation without stentecl sidle branches does not change renal artery motion, potentially allowing significant movement of the renal artery relative to the fenestration. Routine stenting of fenestrations limits postoperative renal artery niotion to 0.3 mm, thereby preventing significant branch movement in relation the fenestration. [ABSTRACT FROM AUTHOR] |
