Diagnostic utility of ultrasound-guided fine-needle aspiration and needle-core biopsy sampling of canine splenic masses.

This prospective clinical study sought to determine the accuracy of cytopathologic examination and needle-core biopsy (NCB) against diagnoses obtained by excisional histopathology (EH) for canine splenic masses. Twenty-five masses were evaluated by ultrasound-guided fine-needle aspiration (FNA) and NCB tissue sampling. Each spleen was placed in a container and artificial skin placed over its surface.

American Canine Hepatozoonosis Causes Multifocal Periosteal Proliferation on CT: A Case Report of 4 Dogs.

American canine hepatozoonosis (ACH) represents an important but relatively uncommon differential diagnosis in a dog with fever, muscle wasting, profound leukocytosis, and/or musculoskeletal pain. Despite this, obtaining a definitive diagnosis can prove difficult. Peripheral blood smears and whole-blood polymerase chain reaction (PCR) rely on rare parasitemia, and the gold standard diagnostic test (skeletal muscle biopsy) is uncommonly pursued due to its invasive and costly nature.

In vitro effect of hydroxyethyl starch on coagulation in dogs as assessed by dynamic viscoelastic coagulometry.

Objective: To evaluate the effect of 6% hydroxyethyl starch (HES) 670/0.75 and 6% HES 130/0.4 dilution of canine whole blood on coagulation using dynamic viscoelastic coagulometry (DVC).

Objective: To evaluate outcomes of dogs with parathyroid carcinoma (PTC) treated by surgical excision and to describe the incidence of postoperative hypocalcemia, degree of hypocalcemia, duration of hospitalization, duration of calcium supplementation, and survival time.

Animals: 100 client-owned dogs with PTC admitted to academic, referral veterinary institutions.

Procedures: In a retrospective multi-institutional study, medical records of dogs undergoing surgical excision of PTC between 2010 to 2019 were reviewed.

Evaluation of the intervertebral disk, vertebral body, and spinal cord for changes secondary to percutaneous laser disk ablation.

Objective: To evaluate the intervertebral disk, vertebral endplates, and spinal cord for perioperative changes secondary to percutaneous laser disk ablation (PLDA) and correlate findings to clinical outcomes in dogs receiving thoracolumbar PLDA.

Study Design: Blinded study.

Animals: Thirty dogs.

Outcomes of dogs undergoing immediate or delayed surgical treatment for gastrointestinal foreign body obstruction: A retrospective study by the Society of Veterinary Soft Tissue Surgery.

Objective: To evaluate gastrointestinal injury and outcomes between dogs treated with immediate surgical intervention vs those treated with delayed surgical intervention for gastrointestinal foreign body obstruction (GIFBO).

Study Design: Retrospective cohort study.

Sample Population: Client-owned dogs (n = 855) from five referral hospitals.

Retrospective multicentric study comparing durations of surgery and anesthesia and likelihoods of short- and long-term complications between cats positioned in sternal or dorsal recumbency for perineal urethrostomy.

Objective: To compare the durations of surgery and anesthesia and the likelihoods of short- and long-term postoperative complications between cats positioned in sternal recumbency versus dorsal recumbency for perineal urethrostomy (PU).

Animals: 247 client-owned cats that underwent PU between January 2004 and December 2015 at 6 veterinary teaching hospitals and 1 private veterinary referral hospital.

Procedures: Medical records were reviewed, and signalment, presenting complaints, previous history of urethral obstruction or PU, diet fed, medications administered, indication for PU, durations of surgery and anesthesia for PU, suture type and size, suture pattern for skin closure, and short- and long-term postoperative complications were recorded.

Analysis of outcomes following treatment of craniodorsal hip luxation with closed reduction and Ehmer sling application in dogs.

To describe outcomes for dogs after treatment of craniodorsal hip luxation with closed reduction and Ehmer sling placement and investigate potential risk factors for sling-associated tissue injury or reluxation of the affected hip at or near the time of sling removal. Retrospective multicenter cohort study. 92 dogs.

Pulmonary artery banding in a cat with a perimembranous ventricular septal defect and left-sided congestive heart failure.

CASE DESCRIPTION A 6-month-old sexually intact male domestic shorthair cat was referred for evaluation of a heart murmur and ventricular septal defect (VSD). CLINICAL FINDINGS Physical examination revealed a grade 5/6 right apical systolic heart murmur. Findings on thoracic radiography were consistent with moderate right and left ventricular enlargement, left atrial enlargement, and enlargement of the pulmonary arteries and veins; an interstitial pulmonary pattern was also evident.

Comparison of methohexital and propofol as induction agents for evaluation of laryngeal function in healthy dogs.

Objective: To determine the influence of propofol or methohexital, with and without doxapram, on the examination of laryngeal function in dogs.

Study Design: Experimental study.

Animals: Forty healthy dogs randomly assigned to 4 groups: propofol with saline (n = 10), propofol with doxapram (n = 10), methohexital with saline (n = 10), or methohexital with doxapram (n = 10).

Surgical ligation of patent ductus arteriosus in a dorper sheep.

Objective: To report the diagnosis and treatment of a companion dorper wether with patent ductus arteriosus (PDA).

Study Design: Case report.

Animal: An 8-month-old dorper wether presented to its primary care veterinarian for a persistent cough and was referred for suspected heart failure on the basis of physical examination and thoracic radiography.

Recurrence of disk herniation following percutaneous laser disk ablation in dogs with a history of thoracolumbar intervertebral disk herniation: 303 cases (1994-2011).

OBJECTIVE To determine rate of recurrence of disk herniation in dogs that underwent percutaneous laser disk ablation (PLDA) because of a previous episode of suspected or confirmed thoracolumbar intervertebral disk herniation (IVDH). DESIGN Retrospective case series. ANIMALS 303 dogs that underwent PLDA and for which a minimum of 3 years of follow-up information was available (n = 294) or for which recurrence was documented within 3 years after the procedure (9).

Thyroglossal Duct Carcinoma in a Cat.

A 14 yr old castrated domestic shorthair cat presented for a fluid-filled structure in the ventral cervical region that had been present for 1 yr and had not resolved after repeated aspiration and drainage. Cervical computed tomography showed an approximately 10 cm, fluid-filled, multilobulated mass located on the ventrolateral right side of the cervical region extending into the thoracic inlet. Cytologic examination of the fluid revealed cystic fluid with evidence of chronic hemorrhage.

Traumatic lung injury attributed to tornadic activity-induced barometric pressure changes in two dogs.

CASE DESCRIPTION A 7-year-old castrated male Italian Greyhound (dog 1) and an approximately 1-year-old female Labrador Retriever (dog 2) were evaluated because of respiratory distress 8 and 10 days, respectively, after a tornado. CLINICAL FINDINGS No obvious external injuries were identified auscultation revealed decreased bronchovesicular sounds in the affected hemithorax of both dogs. Clinicopathologic changes were mild, with evidence of inflammation in both dogs.

An Unusual Case of Metastatic Seminoma in a Dog.

An 8 yr old, reportedly castrated male Boston terrier presented with a history of generalized hyperesthesia and intermittent shifting leg lameness. Physical examination revealed a caudal abdominal mass and bilateral shoulder pain. A complete blood count, serum biochemistry panel, and urinalysis were unremarkable.
