Description of activity and work performed
The authors performed over 50 CEUS examinations in 27 EVAR patients in 6-month and 12-month period after the treatment.
The CEUS examinations were performed using two-bolus method,
using the first intravenous bolus of contrast media (SonoVue,
1,2 mL) to identify a possible endoleak,
and using the second intravenous bolus of contrast media (SonoVue,
1,2 mL) for further endoleak characterisation (early/late endoleak).
The results were compared with CT-angiography scans.
Endoleak type 2 was detected in three patients (11%),
in two cases caused by retrograde flow via lumbar arteries,
and in one case caused by retrograde flow via inferior mesenteric artery.
CT-angiography has verified CEUS findings in all patients (100%) agreement.
