Emergency transcatheter arterial embolization for patients with acute massive duodenal ulcer hemorrhage

Figure 2 Angiographic changes before and after embolization of the gastroduodenal branch by microcatheter. A: Micro-catheter super-select to the gastroduodenal artery branch for angiography, and the exo-contrast agent is shown (indicated by the arrows); B: After embolization by micro-catheter, angiography showed that the bleeding had stopped; the distal end of the bleeding artery was kept open, to avoid widespread ischemia of normal tissue.
