Background: Occurrence of low blood taurine concentrations (B-TauC) and predisposing factors to taurine deficiency in English Cocker Spaniels (ECS) are incompletely understood.

Objectives: Investigate the occurrence of low B-TauC in a Swedish population of ECS and evaluate the association between B-TauC and dog characteristics, clinical variables, and diet composition.

Animals: One-hundred eighty privately owned ECS.

Myxomatous mitral valve disease (MMVD) is the most common acquired heart disease in dogs and its occurrence in small-and medium-sized dogs has been extensively investigated. MMVD has been described in large breed dogs as well, but substantial knowledge gaps remain. The aim of this study was to provide characteristics, survival times, and prognostic variables in large breed dogs with MMVD.

Aim: Determining the added value of preoperative geriatric screening (POGS) in the care path 'Infrarenal abdominal aortic aneurysm'.

Design: Retrospective observational study in a university hospital.

Method: For patients (>60 years) with non-acute aortic pathology, data on preoperative screening (including frailty measures) and treatment was automatically generated from medical records for the period 2018-2021 (42 months).

A 3-year-old Chihuahua was presented because of exercise intolerance, respiratory distress, and syncopal episodes. At the age of 10 weeks, the dog was diagnosed with a congenital small left-to-right shunting ventricular septal defect and a mild right ventricular outflow tract obstruction via echocardiography. At that time, the dog was asymptomatic, but the breeder's veterinarian heard a murmur.

Background: For surgical treatment of primary aortic infection and aortic graft infection, in situ reconstruction with autologous vein(s) has the lowest rates of re-infection and of graft thrombosis. In this study, we have assessed the outcome after autologous femoral vein reconstruction in patients with aortic (graft) infection and we provide insights into the specific technical surgical considerations of the procedure.

Methods: In this retrospective single-center study, all patients who underwent autologous femoral vein reconstruction because of primary aortic infection or aortic graft infection between January 2012 and January 2020 were included.

Background: The objective of our study was to analyze the efficacy of autologous superficial femoropopliteal vein reconstruction for primary aortic or aortic graft infection.

Methods: We performed a retrospective analysis of 14 patients treated for an infected aortic prosthesis or primary infected aorta between 2012 and 2014. Three patients had a primary mycotic aneurysm caused by a Salmonella or Coxiella burnetti infection.

Purpose: To evaluate the short-term feasibility, efficacy, and safety of a modular bifurcated stent-graft with an internal iliac artery (IIA) side branch for endovascular repair of aortoiliac aneurysms.

Methods: Between 2002 and 2005, 10 male patients (median age 75 years, range 59-83) were treated with a bifurcated stent-graft that included a unilateral side branch for the IIA. The median diameters of the abdominal aortic and common iliac artery (CIA) aneurysms were 56 mm (range 33-80) and 40 mm (range 27-60), respectively.
