Abstract: Objective To investigate the role of contrast enhanced ultrasound (CEUS) in detecting type Ⅰ and Ⅱ endoleaks after endovascular abdominal aortic aneurysm repair (EVAR).Methods PostEVAR patients who met the inclusion criteria were enrolled.All of patients underwent CEUS and computer tomography angiography (CTA) examination.The following parameters were evaluated:ultrasound contrast agent within aneurysmal sac,location and source of endoleaks,wash-in time of endoleaks and stentgraft since contrast agent injection.Analysis was performed to observe different types of endoleak features in CEUS.Results Nine cases were enrolled and all the cases had endoleaks.Three cases were type Ⅰ,6 cases were type Ⅱ.The wash-in time of type Ⅱ endoleaks delayed 9.8 seconds compared to type Ⅰ,and the results of CEUS diagnosis were consistent with CTA.Conclusions CEUS is an effective way to detect endoleaks.This technique can be used as a supplement for CTA in follow-up of post-EVAR patients.
