Complications and expected imaging findings after endoscopic retrograde cholangiopancreatography

Figure 11  Hepatic pseudoaneurysm. A and B: Axial (A) and coronal (B) computed tomography (CT) angiography in the arterial phase. C: Digital subtraction angiography during therapeutic intervention. A 63-year-old female patient presented with a rapid drop in hemoglobin and melena following the removal of a previous plastic stent. The patient developed progressively worsening periumbilical abdominal pain and exhibited signs of hypovolemic shock. Arterial phase CT angiography revealed a pseudoaneurysm originating from the left hepatic artery (yellow arrows). The digital subtraction angiography image showed successful embolization of the pseudoaneurysm with coil placement (blue arrow).
