Cross-section through the 2 common iliac artery aneurysms. Retained patency of both legs of the stent-graft is shown by using the color Doppler mode. The blood flow in the aneurysm leg was not visualized, in addition to the lumen of the stent-graft; 1 - stent-graft lumen; 2 - aneurysm sack. Modality: (A) color Doppler, (B) power Doppler, (C) advanced dynamic flow (ADF).

The blood follow inside of the sack of the aneurysm was not observed (Figure 1A-1C).
(A) mSMI: the cross-section through the two common iliac artery aneurysms. 1 The zone flow in the aneurysm sack of the left common iliac artery. (B) mSMI: a longitudinal section through the sack of the left common iliac artery aneurysm. 1. The zone flow in the aneurysm sack of the left common iliac artery.

The flow zone was seen in trans-verse and longitudinal sections (Figure 2A, 2B). cSMI imaging enabled the visualization of similar images (Figure 3) but it was less pronounced than in the case of mSMI imaging.

By the end of the examination, CEUS imaging was obtained and the presence of an endoleak into the iliac artery aneurysm was revealed (Figure 4).
