Abstract
Results: Of all cases, 10 (13.9%) endoleaks were detected using CTA. All five type I and III endoleaks requiring an intervention were detected by both modes of CDUS, while four of the five type II endoleaks were not. The single case of type II endoleak was suspected following the visualization of fresh thrombus formation. There was an inadequacy in detecting low flow endoleaks both using BFI and standard color Doppler mode. There was a strong correlation between the aneurysmal sac diameters measured using CTA and CDUS.
Conclusion: The CDU and BFI are capable of detecting type I and III endoleaks with similar sensitivity and specificity. These modes should be used in combination as confirmatory tests. For surveillance, CDUS promises accurate results without missing any potential complication requiring an intervention. Lack of detecting type II endoleaks may be negligible, as sac enlargement is the key for reintervention in this case.
