Abstract

Abstract Background: The endovascular techniques for repair of thoracic aortic aneurysms are significantly increased nowadays, so the possibility of endoleak is also raised.
Aim of Work: Pre-operative evaluation of the aortic aneu-rysm using the sac size as a predictor for endoleak after endovascular repair of the thoracic Stanford B dissecting aortic aneurysms.
Methods: The study was carried over one hundred and seven patients (88 males and 19 females, range 50-75 year old) from October 2016 to November 2017. Pre and post operative evaluation of all examined patients was done using Multislice CT angiography. Types of endoleak were docu-mented as well as the detailed assessment of the rest of the vascular tree was also done. Results: Receiver Operating Characteristics (ROC) curve analysis was performed for aneurysm sac size, area under the curve (AUC) was nearly optimal 0.938 (95% CI 0.891-0.984). The most suitable cut off point for aneurysm sac size was more than or equal to 6.2cm with sensitivity 83.9% and specificity 85.5%.
Conclusion: Based on our results, aneurysmal sac size combined with patient's age can be used as predictors for post interventional endoleak.
