Vascular anomaly as a cause of late bleeding after endoscopic retrograde cholangiopancreatography: A case report

Figure 1 Bleeding part. A: Bleeding from a small branch of the gastroduodenal artery; B: Bleeding from a small arterial branch of the gastroduodenal artery supplying the left lobe of the liver; C: Bleeding from a small arterial branch of the right hepatic artery anastomosing with the left hepatic artery.

Figure 3 Disappearance of the bleeding point. A: After interventional embolization, the bleeding points in the small branches of the gastroduodenal artery were no longer detectable; B: After interventional embolization, the bleeding points in the small arterial branch of the gastroduodenal artery supplying the left lobe of the liver were no longer detectable; C: After interventional embolization, the bleeding points in the small arterial branch of the right hepatic artery anastomosing with the left hepatic artery were no longer detectable.
