Duodenal ulcer caused by coil wiggle after digital subtraction angiography-guided embolization: A case report

Figure 1  Esophagogastroduodenoscopy performed seven days before the acute gastrointestinal bleeding.

Figure 2 Digital subtraction angiography images before and after arterial embolization. A: Digital subtraction angiography image showed extravasation of contrast agent at the branch of gastroduodenal artery (orange arrow); B: Digital subtraction angiography showed successful embolization of gastroduodenal artery branch.
