CT angiography of acute aortic syndrome in patients with chronic kidney disease.

The term acute aortic syndrome (AAS) refers to a range of different entities, including dissection, intramural haematoma and penetrating atherosclerotic ulcer. Patients with chronic renal disease and particularly those with dominant polycystic kidney disease are susceptible to this pathology, given the underlying renal arteriopathy and hypertension. Imaging plays a crucial role in diagnosing, grading and guiding management of these patients, with computed tomography angiography (CTA) being on the frontline.

Translumbar and Transhepatic Tunneled Dialysis Catheter Placements in the End Stage Renal Disease Population.

For end-stage renal disease (ESRD) patients requiring hemodialysis, reliable vascular access is crucial, especially when conventional supradiaphragmatic options are exhausted. This study reviews the technical aspects, clinical outcomes, and complications of translumbar and transhepatic tunneled dialysis catheter (TDC) placements. These alternative infradiaphragmatic approaches provide essential hemodialysis access for patients with central venous occlusions.

Diagnostic performance of Photon-counting CT angiography in peripheral artery disease compared to DSA as gold standard.

Background: Photon-counting (PC) CT has the potential to improve diagnostic confidence and image quality of CT angiography (CTA) in patients with peripheral artery disease (PAD).

Purpose: To retrospectively evaluate the diagnostic performance of Photon-counting CT angiography for the assessment of stenotic disease in patients with PAD compared to digital subtraction angiography (DSA) as gold standard.

Materials And Methods: All patients undergoing PC CTA followed by DSA between November 2021 and November 2023 were included in this institutional review board approved HIPAA compliant retrospective analysis.
