Figure 3 (A-D): USG-guided thrombin injection. (A) Gray-scale image shows anechoic pseudoaneurysm arising from the anterior branch of right hepatic artery, which shows yin-yang pattern of color flow within (B) indicating recanalization (C) Shows USG-guided placement of 22G needle tip within the pseudoaneurysm (D) Increased echogenicity within the pseudoaneurysm is observed following thrombin injection and there is absence of color flow, suggestive of complete thrombosis
