Study index: 96-10 Vendor Acuson Modality US Examination Ultrasound: Liver Findings Within the previously identified hepatic artery aneurysm there is now an echogenic focus consistent with embolization coils and less echogenic material representing thrombus within the aneurysm. A focal 1-cm hypoechoic area is seen adjacent to the area of echogenicity. Flow is seen within this area consistent with minimal residual aneurysm flow. The flow is seen to have an arterial wave form. Hepatic Artery Aneurysm with predominant clot within lumen following embolization. 1-cm residual focus with arterial flow present.
