Factors Influencing on the Aneurysm Sac Shrinkage after Endovascular Abdominal Aortic Aneurysm Repair by the Analysis of the Patients with the Aneurysm Sac Shrinkage and Expansion

Figures

• 

  Fig. 1 Period until sac shrinkage or expansion 5 mm detection or follow-up period for patients with sac diameter change less than 5 mm. The longest follow-up period for patients with the sac diameter change less than 5 mm was shorter than the longest period until shrinkage or expansion 5 mm detection.

  Fig. 2 ROC analysis for aneurysm sac shrink/expand and number of patent LA at the end of EVAR. Significant relationship was observed between aneurysm sac shrink/expand and number of patent LA by ROC analysis (AUC = 0.7556, p = 0.0003). The cutoff value of patent LA number was estimated as 2 by the Youden’s index. ROC: receiver operating characteristic; EVAR: endovascular aneurysm repair; LA: lumbar artery; AUC: area under the curve.
