Purpose: To assess the various dimensions of an iliac branched device (IBD), after endovascular repair of an iliac aneurysm, with the use of an innovative computed tomography (CT) analysis software. Method: Retrospective case-control study conducted with a prospective kept database of 31 patients, electively treated for an aortoiliac aneurysm. The pre- and postoperative neck surfaces, diameters and curvature of the iliac arteries were calculated in the external iliac artery (EIA) and internal iliac artery (IIA). The postoperative apposition of the stentgraft with the arterial wall was calculated by determination of the endograft apposition area, shortest apposition length, and the percentage of arterial wall occupied by the stent. The maximum distortion ratio (D ratio) was determined postoperatively in the IIA to determine its influence on long-term outcomes and the applicability of the measurement. Results: Postoperative analysis of graft position shows that insufficient apposition is often achieved in the IIA, in contrast to the EIA. In doing so, the analysis shows that the origin, extent and location of postoperative complications can be accurately visualized. Conclusion: This is the first study focusing on the dimensions of the IBD in the IIA and EIA after deployment. The3mensio workstation and VIA software offer the option to accurately visualize the pre-operative arterial anatomy and morphology, and post-operative acquired apposition. In addition, we conclude that measurement of the D-ratio is an easily executable measurement which gives an accurate indication of the degree and location of fragile sites in the IIA sidebranch, which may be correlated to late occlusion of the AII.
