Computed Tomographic Findings in Dogs with Hepatic Bacterial Parenchymal Infection and Abscessation.

Animals (Basel)

November 2024

Southern Counties Veterinary Specialists, Independent Vetcare (IVC) Evidensia, Forest Corner Farm, Hangersley, Ringwood BH24 3JW, UK.

Bacterial liver parenchymal infections in dogs are rarely documented, and their imaging characteristics are scarce in the veterinary literature, especially in Computed Tomography (CT). This retrospective multicentric study aimed to describe the CT characteristics of parenchymal bacterial liver infection and abscessation in dogs and compare them with the human literature. Twenty dogs met the inclusion criteria.

Hepatic parenchymal hypoattenuation in dogs with diabetes mellitus on computed tomography consistent with hepatic steatosis.

Vet Radiol Ultrasound

January 2025

Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Purdue University, West Lafayette, Indiana, USA.

Hypoattenuation of the liver, consistent with hepatic steatosis or lipidosis, has been reported in veterinary patients. In people, measuring CT hepatic attenuation is diagnostic for hepatic steatosis, and hypoattenuation of the liver is defined as absolute if less than 40 HU or relative if the liver is 10 HU less than the spleen. The purpose of this study is to describe hepatic parenchymal attenuation in dogs with diabetes mellitus with or without diabetic ketosis (DK) or diabetic ketoacidosis (DKA), using the above categorization for absolute and relative hypoattenuation, as with humans.

Article Synopsis
  • The study investigates the relationship between elevated levels of lipoprotein(a) [Lp(a)] and high-sensitivity C-reactive protein [hs-CRP] and the occurrence of hypoattenuating leaflet thickening (HALT) following transcatheter aortic valve replacement (TAVR).
  • It included 307 patients who underwent TAVR, with 36.2% showing HALT within a year; results indicated that higher levels of both Lp(a) and hs-CRP significantly increased the risk of HALT.
  • Specifically, individuals in the top 25th percentile for both biomarkers had a 4.74 times greater risk of developing HALT, highlighting the importance of these markers in post-TAV

Article Synopsis
  • An adult tawny owl with head trauma showed severe neurological issues, including lethargy and an unresponsive left pupil during examination.
  • A series of tests, like CT scans and auditory responses, indicated brain damage and altered visual pathways, suggesting serious impacts from the trauma.
  • Understanding bird neurological injuries is crucial for prevention and treatment, highlighting the importance of advanced diagnostic tools in veterinary care.

Background: Device-related thrombosis (DRT) is a known complication to left atrial appendage closure (LAAC). The surface of a LAAC device should ideally have antithrombotic properties. The novel WATCHMAN FLX Pro (WFP) incorporates a fluoropolymer-coated fabric membrane designed to increase thromboresistance and facilitate endothelialization.
