    Abstract:
    Unlike other visceral artery aneurysms, pancreaticoduodenal artery aneurysms (PDAAs) should be treated regardless of their size. There are no reports on PDAA associated with celiac artery (CA) dissection. We, here, report the case of a patient with a ruptured PDAA with concomitant CA dissection. A 44-year-old Korean man presented to the emergency room of another hospital 29 days ago due to a sudden onset of abdominal pain. Contrast-enhanced abdominal computed tomography (CT) revealed a large right retroperitoneal hematoma and CA dissection. Subsequently, aortography revealed no specific bleeding focus. He underwent conservative treatment for 16 days, including a transfusion, and then was referred to us. His abdominal CT angiography revealed a diminishing retroperitoneal hematoma, a 7 mm × 8 mm PDAA at the anterior inferior pancreaticoduodenal artery aneurysm (PDA), and CA dissection. Selective celiac angiography revealed sluggish and diminished blood flow to the true lumen of the CA, and the hepatic, gastroduodenal, and splenic arteries were supplied by collaterals arising from the superior mesenteric artery (SMA). We performed elective coil embolization of the anterior PDA using the right femoral approach.We believe that postprocedural surveillance is required after CA dissection because of the potential risk of recurrent PDAA. Additionally, we suggest that hidden PDAA rupture should be considered for spontaneous retroperitoneal bleeding.
