title: Endoaortic stent grafting of a giant infected hepatic-celiac pseudoaneurysm.
abstract: A 72-year-old man was admitted because of progressive right upper-abdominal distension and pain as well as concurrent remittent fever for 5 months. He had undergone a radical gastrectomy and catheter intubation in the common hepatic artery for chemotherapy 12 months before admission. The diagnosis of giant infected hepatic-celiac artery pseudoaneurysm was established. Coils embolotherapy was given in another hospital, but it failed. After admission, a computed tomographic aortogram showed a mass 10.3 x 8.5 x 8.1 cm in size in the right upper abdomen that originated from the common hepatic artery and the celiac artery. A celiac-super mesenteric artery (SMA) double catheter simultaneous digital subtraction angiography (DSA) further revealed that the entrance of the aneurysm opened directly from the abdominal aorta, the distance between the orifice of SMA and celiac axis was only 0.5 cm, and the diameter of the celiac trunk had been aneurysmally enlarged to 2.0 cm. A blood culture was positive for Bacillus pyocyaneus. After detailed discussion and preparation, a stent-graft complex was negotiated through the left femoral artery and deployed successfully into the abdominal aorta to seal the orifice of celiac trunk under the dynamic supervision of DSA. Completion angiography revealed that the hepatic-celiac pseudoaneurysm was completely excluded from aortic flow by the endoluminal stent-graft complex, while the SMA and renal arteries remained perfectly patent. The patient recovered uneventfully and was discharged without any residual symptoms. At a 5-year follow-up, the patient remained asymptomatic and was leading a normal life.
