Prognostic Factors in 26 Cats Undergoing Surgery for Extra-Hepatic Biliary Obstruction.

Surgical management of feline extra-hepatic biliary obstruction (EHBO) has poor survival rates with few prognostic factors reported in the literature. The etiology and clinical findings of feline EHBO and their influence on short-(2 weeks-6 months) and long-term (>6 months) survival and prognosis were examined in an observational clinical retrospective study of 26 client-owned cats undergoing surgery for biliary obstruction at one institution between 2012 and 2020. The etiology of EHBO was determined in 21/26 cats, which included inflammatory causes (14/21), neoplastic causes (6/21), and a duodenal foreign body (1/21).

Evaluation of a porcine vascular model to assess the efficacy of various hemostatic techniques.

Background: A novel live porcine model replicated the endoscopic surgical field of a carotid arterial injury of the human skull base. Hemostatic techniques were applied to jugular venous and carotid arterial injuries, including muscle patches, hemoclips, and aneurysm clips. Doppler imaging distal to the injury assessed flow through the repaired vessel.
