Balloon expandable aortic stent-graft for the treatment of aortic aneurysm and rupture in a dog.
J Vet Emerg Crit Care (San Antonio)
November 2021
Department of Small Animal Surgery, The Veterinary Teaching Hospital, Koret School of Veterinary Medicine, The Hebrew University of Jerusalem, Rehovot, Israel.
Objective: To describe the successful placement of an aortic stent graft in a dog suffering from aortic aneurysm and rupture.
Case Summary: A 4-year-old neutered female mixed breed dog weighing 25 kg was presented with a chief complaint of acute onset of weakness and respiratory distress. On presentation, the dog was lateral and unresponsive, hypothermic, tachycardic, and tachypneic.
Assessing Patient-Specific Mechanical Properties of Aortic Wall and Peri-Aortic Structures From In Vivo DENSE Magnetic Resonance Imaging Using an Inverse Finite Element Method and Elastic Foundation Boundary Conditions.

The establishment of in vivo, noninvasive patient-specific, and regionally resolved techniques to quantify aortic properties is key to improving clinical risk assessment and scientific understanding of vascular growth and remodeling. A promising and novel technique to reach this goal is an inverse finite element method (FEM) approach that utilizes magnetic resonance imaging (MRI)-derived displacement fields from displacement encoding with stimulated echoes (DENSE). Previous studies using DENSE MRI suggested that the infrarenal abdominal aorta (IAA) deforms heterogeneously during the cardiac cycle.

Department of Radiology of the Erasmus University Medical Center, Rotterdam, The Netherlands.
Objective: The Bentall procedure is associated with several complications often accompanied by accumulation of fluid around the aortic graft. CT is the imaging modality of choice to detect these complications. Since these early complications are, however, not easily distinguished from physiological postoperative changes, our aim was to compare the appearance and amount of peri-aortic fluid on early CT scans following Bentall procedures with either an uncomplicated or a complicated course and follow-up.

Background: The majority of aorto-caval fistulae occur spontaneously, either as a result of rupture of an existing atherosclerotic abdominal aortic aneurysm into the vena cava or secondary to iatrogenic injuries during peripheral angiography or surgery. Aorto-caval fistula from an infected aortic aneurysm is a rare scenario, but potentially lethal.
Methods: Case report and review of the literature.
