A Case of Life-threatening Rupture of Small Renal Angiomyolipoma with an Unidentified Intratumoral Aneurysm during Follow-up.

We report a case of a life-threatening ruptured renal angiomyolipoma (AML) that did not meet the criteria for prophylactic treatment (tumor >4 cm or intratumoral aneurysm >5 mm) during follow-up. A woman in her 70s was followed up for a 2.5-cm AML with a rich vascular component.

Major and minor complications of the pancreas after transcatheter arterial embolization using n-butyl-2-cyanoacrylate for acute bleeding from pancreatic arteries.

Purpose: The purpose is to investigate the major and minor complications of the pancreas after transcatheter arterial embolization (TAE) using n-butyl-2-cyanoacrylate (NBCA) for bleeding from pancreatic arteries.

Materials And Methods: Thirty-three patients who underwent TAE using NBCA for acute bleeding from pancreatic arteries and their parent arteries followed by contrast-enhanced computed tomography (CE-CT) were evaluated retrospectively. Complications and risk factors were assessed using Mann-Whitney U test or Fisher's exact test for the univariate analysis.
