 A 71-year-old man experienced bleeding on day 8 after duodenal GIST resection. a: Pseudoaneurysm of GDA (⇧). b: Since there was no evidence of active bleeding and the patient’s general condition was stable, the PHA was balloon-occluded, and hemostasis was achieved with coil embolization at the GDA transection (black arrow). c: Contrast image after GDA transection coil embolization (black arrow). The procedure was terminated after confirming that there was no bleeding and that the hepatic blood flow was preserved. The following day, bleeding from the drain was observed, and another angiogram was performed. d: Hemorrhage from the dorsal pancreatic artery was observed (⇧). e: The dorsal pancreatic artery is coil-embolized (black arrow), and a Viabahn stent graft was inserted to close the GDA coiling area (white arrow). f: The procedure was terminated after confirming hepatic arterial blood flow and hemostasis. Abbreviations: GDA, gastroduodenal artery; GIS, gastrointestinal stromal tumor; PHA, proper hepatic artery
