Aim

Evaluate intraoperative 3D CEUS vs uniplanar angiography during EVAR

Endoleak

Stent deformity

Renal artery perfusion

methods
Methods

Prospective study of consecutive infrarenal EVAR

Completion angiogram & 3D CEUS

Presence of endoleak characterised along with renal perfusion and device deformity

results
Results

19 paired 3D CEUS and completion angiograms

Endoleak:

3 on angiogram (Type 1a and 2x Type 2)

10 endoleaks with 3D CEUS (3x Type 1, 6 Type 2 and 1 Type 3)

1 patient: 3D CEUS identified 1a and 2b  neck ballooned  1a resolved

results1
Results

All renal arteries were patent on completion angio and 3D CEUS

No endograft deformity

Flow characteristics quantified by duplex in all cases

evar in patients with ckd
EVAR in patients with CKD

2 patients with CKD IV underwent EVAR using CO2 angiography and 3D CEUS

1 patient – no iodinated contrast

1 patient – 5ml contrast

Full completion imaging

No reduction in GFR

discussion
Discussion

3D CEUS identifies and characterises endoleak following stent graft deployment

Alternative to completion angiography

Allows quality control of EVAR with ultra-low or no iodinated contrast
