Use of ultra-low contrast dose CT aortography for the management of aortic aneurysmal disease.
J Cardiothorac Surg
October 2024
Department of Radiology, Westmead Hospital, Sydney, NSW, 2145, Australia.
Article Synopsis
- The study explores using low volumes of iodinated contrast in computed tomography aortography (CTA) to minimize the risk of kidney damage in patients with severe renal insufficiency.
- It involved 12 CTA scans performed with only 20 mL of contrast to assess the image quality, using both quantitative (signal-to-noise and contrast-to-noise ratios) and qualitative evaluations by medical professionals.
- Results showed that most scans met quality standards for diagnosis and surgical planning, suggesting that ultra-low contrast volumes can be effective and safe for high-risk patients.
Trash Feet and Mesenteric Ischemia as a Rare Manifestation of a Complicated Abdominal Aortic Aneurysm: A Case Report.
Vasc Endovascular Surg
February 2025
Service of Vascular Surgery and Angiology, Ospedale Regionale di Lugano, Centro Vascolare Ticino, EOC, Lugano, Switzerland.
Background: Abdominal aortic aneurysms and atheromatous plaques are well-established potential culprits in the development of cholesterol embolization. This embolic phenomenon can result in the occlusion of peripheral arteries in the forefoot or toes, commonly referred to as "trash foot".
Case: A 61-year old patient exhibited severe symptoms and signs of lower limb and mesenteric ischemia, represented clinically by abdominal pain, hematochezia, and bilateral plantar necrotic lesions, attributed to embolization from a previously unknown large infrarenal abdominal aortic aneurysm.
The Use of Advanced Three-Dimensional Computed Tomography During Simple and Complex Endovascular Aortic Aneurysm Repairs.
Ann Vasc Surg
September 2024
Department of Vascular Surgery, Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, CA.
Background: Endovascular aneurysm repair (EVAR) success depends on imaging technology both in the planning and operative phases. Endovascular repair requires intravenous contrast and radiation exposure to the patient as well as radiation exposure to the operator. Recent developments in imaging technology attempt to merge preoperative imaging with intraoperative imaging to improve the efficiency and accuracy of EVAR.

December 2024
Department of Vascular Surgery, Heart Vascular and Thoracic Institute, Cleveland, OH, USA.
Introduction: Aortic graft infection (AGI) is a rare complication following endovascular aneurysm repair and is associated with substantial morbidity and mortality. The traditional management of AGI is intravenous antibiotic therapy and surgical explantation. In this case series, percutaneous drainage was used as a bridge therapy in the treatment of AGI.

May 2023
Division of Vascular Surgery at VCU Health, Richmond, VA. Electronic address:
Background: Post endovascular aneurysm repair (EVAR), surveillance with computed tomography-aortography (CTA) remains the most common practice, per Society for Vascular Surgery (SVS) guidelines. Chronic exposure to both radiation and intravenous (IV) contrast has raised concerns about long-term CTA follow-up (FU). As we have selectively used ultrasound (US) as a sole modality for post-EVAR surveillance, we sought to review our outcomes in this subset of patients.
