Celiac artery stenting: a new strategy for patients with pancreaticoduodenal artery aneurysm associated with stenosis of the celiac artery

We report a new strategy—celiac artery stenting—to relieve stenosis of the celiac arterial root. This was performed in two patients with pancreaticoduodenal artery (PDA) aneurysm associated with a stenotic celiac arterial root. The first patient was a 66-year-old man complaining of abrupt onset of upper abdominal pain. Abdominal computed tomography revealed a huge retroperitoneal hematoma behind the duodenum, and superior mesenteric artery (SMA) angiography demonstrated an aneurysm arising from inferior pancreaticoduodenal artery and celiac arteriography showed a stenotic celiac arterial root. Transcatheter embolization of the aneurysm was tried, but failed. Because of his unstable hemodynamics, emergent laparotomy with resection of the aneurysm was performed. Fourteen days after the operation, percutaneous transluminal angioplasty with celiac arterial stenting was done. The patient was discharged 2 days later, and has had no further bleeding episode for 3 years. The second patient was a 46-year-old woman, who also complained of acute upper abdominal pain. Abdominal computed tomography disclosed a huge retroperitoneal hematoma, and selective SMA angiography demonstrated an aneurysm arising from the inferior pancreaticoduodenal artery, and celiac arteriography showed a stenotic celiac arterial root. Because angiography showed no active bleeding from the aneurysm, percutaneous transluminal angioplastic stenting of the stenotic celiac artery was performed. She was discharged 5 days later and has had no further bleeding episode for 2 years. Celiac arterial stenting, as shown in our two patients, could be easily and safely employed in patients with PDA aneurysm associated with a stenotic celiac arterial root to release the stenosis of the celiac arterial root and to prevent further possible bleeding.
