ABSTRACT
PURPOSE:
Sometimes, there are endograft shortenings during endovascular aneurysm repair (EVAR). They are associated with various changes of endograft position in a 3-dimensional (3D) space. The purpose of this study is to evaluate the accuracy of central luminal line (CLL) measurements and understand the degree of endograft shortenings.METHODS:
Preoperative 3D computed tomographic (CT) scans were evaluated for every EVAR case. Preoperative working lengths were measured with computerized software that allowed for centerline measurements on 3D reconstructions based on CT data. We compared preoperative CLL measurements and used the endograft length. In this study, the ipsilateral limb length comparisons were excluded, because the overlapped stent-graft length can influence the total ipsilateral limb length. Hence, only the contralateral limb lengths were compared with each other.RESULTS:
Preoperative contralateral lengths in the 9 limbs were studied. There was no large difference (below 10 mm) in almost all cases except for one (15 mm shortening), which was very tortuous aortoiliac anatomy. The mean difference between preoperative CLL measurements and the used stent-graft length was 4.48 mm.CONCLUSION:
Although these shortenings can be overcome with the deployment technique, the operator should prepare various length extensions in tortuous anatomy.
