New predictors of aneurysm sac behavior after endovascular aortic aneurysm repair

A systematic review of anatomic predictors of abdominal aortic aneurysm remodeling after endovascular repair

“…For AAA thrombus, a lower volume percentage was reported as a significant predictor of AAA expansion (HR=0.90, 95%CI 0.84-0.96, p=0.003), and similarly, a larger preoperative absolute volume was significantly associated with more AAA volume shrinkage at 6 months after EVAR (r=+0.41, p=0.03) 21,27 . In addition, a higher mean Hounsfield Unit value of the AAA thrombus was significantly associated with less sac shrinkage (HR=0.97, 95%CI 0.95-0.99, p=0.013) 18 .…”

“…The main findings of each study on the correlation of the anatomical parameter with AAA sac growth and shrinkage are presented in Table III [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] . A total of 27 anatomical parameters were Preoperative neck thrombus was indicated to predict less AAA sac shrinkage after EVAR 19,24,26,33 .…”
