- Abstract
- Purpose : To evaluate the association between the Society for Vascular Surgery/American Association for Vascular Surgery (SVS/AAVS) anatomical severity grading (ASG) score and operative outcomes in fenestrated endovascular repair (f-EVAR) for juxtarenal aortic aneurysm. Methods : A review was conducted of all patients treated at our clinic with commercially available, custom-made f-EVAR devices between June 2007 and December 2011. Preoperative computed tomography (CT) scans were analyzed in a dedicated vascular 3-dimensional workstation for calculation of the ASG score. Of the 100 patients treated with f-EVAR during the study period, 88 (69 men; mean age 70 years, range 50-82) had high quality CT scans available for generating... (More)
- Purpose : To evaluate the association between the Society for Vascular Surgery/American Association for Vascular Surgery (SVS/AAVS) anatomical severity grading (ASG) score and operative outcomes in fenestrated endovascular repair (f-EVAR) for juxtarenal aortic aneurysm. Methods : A review was conducted of all patients treated at our clinic with commercially available, custom-made f-EVAR devices between June 2007 and December 2011. Preoperative computed tomography (CT) scans were analyzed in a dedicated vascular 3-dimensional workstation for calculation of the ASG score. Of the 100 patients treated with f-EVAR during the study period, 88 (69 men; mean age 70 years, range 50-82) had high quality CT scans available for generating semiautomatic centerline-of-flow reconstructions needed to calculate the ASG score. The mean score was used to divide the patients into high and low score groups for comparison of operative outcomes. Results : A total ASG score ≥24 was associated with longer procedure time (357±121 vs. 298±131 minutes, p=0.03) and more frequent intraoperative adjunctive maneuvers (48% vs. 29% of patients, p=0.05). An ASG neck score ≥7 was associated with longer procedure time (365±126 vs. 288±119 minutes, p<0.01), more operative adverse events (31% vs. 14% of patients, p=0.05), higher radiation exposure (53828±37341 vs. 38788±25846 μGym (2) , p=0.04), and more frequent postoperative complications (46% vs. 18% of patients, p<0.01). An ASG aneurysm score ≥5 was associated with operative adverse events (44% vs. 19% of patients, p=0.04). No relationship was found between the ASG score and blood loss, contrast volume, fluoroscopy time, or hospital stays. Conclusion : The ASG score is associated with operative adverse events, intraoperative adjunctive maneuvers, radiation exposure, and postoperative complications in patients treated with f-EVAR for juxtarenal aortic aneurysm.
