EVAR follow-up, type II endoleak detection by color Doppler ultrasound. (A) Aortic cross-sectional view showing right and left limb with a hypoechoic right posterior channel within the aortic thrombus, color Doppler filling of this channel confirms the presence of an endoleak; (B) spectral analysis indicates bidirectional flow along the right posterior margin of the aorta consistent with a type II endoleak from a patent lumbar artery; (C) aortic cross-sectional view showing right and left limb and an anterior flow channel; and (D) spectral analysis indicates bidirectional flow at the anterior margin of the aorta consistent with a type II endoleak from the inferior mesenteric artery.
