摘要: Purpose:To compare unenhanced and enhanced ultrasound imaging to biphasic computed tomography (CT) in the detection of endoleak after endovascular abdominal aortic aneurysm (AAA) repair.Methods:Fifty-three patients (44 men; mean age 70 years) were examined during 96 follow-up visits AAA repair. All had color Doppler power studies performed before administration an contrast agent. Biphasic (arterial delayed) CT was on same day, independently scored record presence or absence level confidence observation.Results:The sensitivity techniques detect improved with use media, ranging from a low 12% 50% Doppler. However, failed 9 type II endoleaks identified by (86% negative predictive value fo...
