Histopathologic diagnosis and patient characteristics in cats with small intestinal obstructions secondary to trichobezoars.

Objectives: The aim of the present study was to describe the distribution of gastrointestinal histopathology findings associated with gastrointestinal obstructions secondary to trichobezoar formation in cats.

Methods: A total of 100 surgical gastrointestinal biopsies were obtained from 44 cats with gastrointestinal obstructions secondary to a trichobezoar. Medical records, including signalment, type and duration of clinical signs, surgical reports and histopathologic analysis, were reviewed for each cat.

Computed tomography angiography aids in predicting resectability of isolated liver tumors in dogs.

Objective: To assess the accuracy of CT angiography (CTA) in predicting resectability, degree of surgical difficulty, and individual factors that may impact resectability of isolated hepatic masses in dogs.

Animals: Prospective study of 20 dogs with 21 isolated hepatic masses.

Procedures: All CTAs and surgeries were performed between June 16, 2013, and November 30, 2016, at The Animal Medical Center in New York.

Evidence of Leptospiral Presence in the Cumberland Gap Region.
