From: Safety and efficacy of emergency transarterial embolization for mesenteric bleeding
A 74-year-old female with spontaneous mesenteric haematoma following a median arcuate ligament syndrome. Axial CT scan (A) showed a pseudoaneurysm without contrast extravasation of a pancreaticoduodenal artery, with mesenteric hematoma (*). Upper mesenteric angiography (B) showed a prominent gastroduodenal artery that feeds the common hepatic artery and confirmed a pseudoaneurysm of 9 mm, without possibility to catheterize the feeding artery (endovascular technical failure). After puncture under ultrasonographic guidance, a fluoroscopic image (C) showed filling of the pseudoaneurysm using contrast agent injection (black arrow) with a 22G-needle. Post embolization contrast-enhanced axial CT scan (D) showed the absence of filling of the pseudoaneurysm (white arrow’s head)
