Analysis of Preoperative CT Scan Can Help Predict Technical Failure of Endovascular Treatment of TASC C–D Aortoiliac Chronic Total Occlusions

Background and Aims To evaluate if features of occlusion analyzable on preoperative computed tomography scan could predict risks technical failure or iliac rupture endovascular treatment TransAtlantic InterSociety Consensus C–D aortoiliac chronic total occlusion. Methods results All patients treated by techniques for a between 2009 2016 were included (107 patients, 148 arteries). We evaluated the location importance arterial calcifications. For this factor, divided into 3 groups: Black group with mild no calcifications, white moderate protrusive heavy endoluminal Technical occurred in 11 arteries peroperative 6. The external artery is most significate risk factor univariate (OR = 9.93; P 0.0012) multivariate analysis 15.26; 0.0006). presence calcifications further 13.88; 0.0365). Rupture rate was comparable groups. Conclusions Preoperative can but not rupture.
