1 Surveillance of a coiled renal artery aneurysm by contrast-enhanced ultrasound with Definity 
Gavin Low, MBChB, MRCS, FRCR, Sean D. Winters, MD, FRCPC, Richard J.T. Owen, MB BCh, MRCP, FRCR  Journal of Vascular Surgery  Volume 54, Issue 6, Pages (December 2011) DOI: /j.jvs Copyright © 2011 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Angiographic images of the left kidney with the catheter tip in the main renal artery. A, Demonstrates a 1.5-cm saccular aneurysm (arrow) originating at the bifurcation of a lower pole branch of the renal artery. Posttreatment image (B) shows a dense Gugliemi Detachable Coil (GDC) mass within the aneurysm sac. No contrast filling of the aneurysm is identified; there is no residual neck demonstrated. The main renal artery and its branches are patent, and there is normal parenchymal enhancement of the kidney.

3 Fig 2 Corresponding sagittal grayscale (A) and color Doppler scan (B) images of the left kidney. A, Shows the aneurysm (arrow) as an echogenic focal area associated with dense posterior acoustic shadowing. In (B), blood flow is seen in the renal artery (arrow), but the coil material prevents assessment of the aneurysm.

4 Fig 3 Corresponding sagittal contrast-enhanced ultrasound scan (A) and grayscale ultrasound scan (B) images of the left kidney. A, Shows no contrast filling of the aneurysm (straight arrow), patency of the adjacent renal artery (curved arrow), and uniform enhancement of the renal parenchyma (star). Dynamic real-time (over continuous 3-minute duration) contrast-enhanced interrogation using multiple imaging projections coupled with magnification of the returning echo signal by a factor of 500 to 1000 times enables contrast-enhanced ultrasound scan to overcome the limitations of standard and color Doppler scan.
