Recent advances in endovascular techniques for management of acute nonvariceal upper gastrointestinal bleeding

Figure 8 Typical sandwich embolization in a 75-year-old woman with bleeding from a postbulbar duodenal ulcer at endoscopy. A: Angiography before embolization, guided by clip position (arrow): no evidence of active bleeding; B: Coil embolization of the distal and proximal gastroduodenal artery (with gelatine sponge in the arterial trunk), including the anterior and posterior superior pancreaticoduodenal arteries and the right gastroepiploic artery, to prevent retrograde flow (arrows). Bleeding stopped and no ischemic complications were reported.
