title: [Hemorrhagic aneurysm of the celiac trunk. Diagnosis by ultrasound, CT and angiography].
abstract: The authors report their experience in the study of bleeding aneurysms of the celiac arteries. Eleven patients were examined with US, CT, and angiography (8 hepatic artery aneurysms and 3 splenic artery aneurysms). Clinical findings included digestive bleeding, upper abdominal pain, palpable pulsating masses, and jaundice. Patient history included blunt abdominal trauma, penetrating trauma due to gunshot, acute pancreatitis, recent hepatic biopsy. In all cases US showed an abdominal mass ranging in size from 2 to 10 cm. US findings included cyst-like lesions (8 cases), a lobulated solid-like lesion, and complex lesions (2 cases). Continuity of the lesion with adjacent arterial vessels was noted in 5/11 cases, and pulsing activity in 3/11 cases. US patterns, although not specific, play an important role in the diagnosis when associated to other elements such as arterial continuity, mass pulsatility, patient history, and gastrointestinal bleeding. They suggest the need for more specific imaging exams, i.e. CT and angiography, and help avoid dangerous diagnostic biopsies. CT was performed to confirm US findings in 5 cases, and detected either hypodense cystic masses, or inhomogeneous masses with arterial enhancement after bolus injection of cm. CT was used to better demonstrate the lumen, patency of the vessel, the walls of the vessel, and the parietal thrombotic component. The typical arterial enhancement was the decisive finding for the diagnosis, even though a total continuity with arterial vessels was never observed. Angiography was the method of choice for the preoperative demonstration of hepatic artery aneurysms (10 cases) and for occlusive treatment with Gianturco coils (3 cases).
