A 4-year-old spayed female Boston terrier was diagnosed with a suspected meningioma involving the optic chiasm and resulting in vision loss. A vascular access port (VAP) was placed in the left medial saphenous vein to facilitate frequent anesthetic episodes for radiation therapy. Five days after placement, the VAP was nonfunctional with the silicon...

This chapter discusses conditions affecting the tarsal region (i.e. any of the structures affecting the tarsal joint and surrounding area). A brief discussion of the clinically relevant local anatomy is followed by a detailed description of the history, physical examination, and diagnostic findings typically found in patients presenting with pathol...

Nontraumatic spontaneous pneumoperitoneum suggests the presence of gastrointestinal perforation; early detection can be lifesaving. Horizontal beam projections have been reported to be more sensitive than standard radiographic views for detecting small volumes of free peritoneal gas. This prospective, experimental, analytical study compared both le...

Two male intact dwarf rabbits (Oryctolagus cuniculus), 20 and 26 months old, were diagnosed with traumatic long bone fractures of the radius/ulna and tibia, respectively. Transfixation pin splinting, a technique adapted from large animal orthopedics, was used to stabilize the long bone fractures in both rabbits. Bony union with return to normal lim...

In properly selected dogs, juvenile pubic symphysiodesis improves joint congruity, decreases hip laxity, and can reverse or prevent progression of degenerative joint disease in the hips. To be effective, surgery must be done at a young age and in hips that are only mildly to moderately lax. Juvenile pubic symphysiodesis is best viewed more as a pre...

Background Cor triatriatum dexter (CTD) is a rare congenital cardiac malformation with various manifestations and has been sporadically described in dogs. Clinically the dogs present with nonspecific signs of right heart failure or Budd-Chiari-like syndrome. Other associated concurrent cardiovascular anomalies are commonly reported. Diagnosis and f...

OBJECTIVE To determine the effect of arthrotomy alone or in combination with osteotomy of the proximal portion of the tibia on blood delivery to the patellar tendon of dogs. SAMPLE 24 canine cadavers. PROCEDURES One hind limb from each cadaver was assigned to 1 of 4 treatment groups: medial arthrotomy (MA; MA group), lateral arthrotomy (LA; LA grou...

An 11 yr old female mixed-breed Siberian husky was presented with a history of sanguineous vaginal discharge, swelling of the perineal area, decreased appetite, and lethargy. A single, large vaginal leiomyoma and multiple mammary tumors were diagnosed. Mastectomy and ovariohysterectomy were performed. The vaginal leiomyoma regressed completely afte...

The unfolded protein response (UPR), a conserved cellular response to stressors such as hypoxia and nutrient deprivation, is associated with angiogenesis and metastasis in tumor cells. This article discusses a pilot study conducted to determine whether components of the UPR could be identified in spontaneous canine tumors and whether they were up-r...

Objective: To determine the prevalence of circumcaval ureters and other caudal vena cava variations in cats and determine whether circumcaval ureters were associated with macroscopic evidence of ureteral obstruction. Sample: 301 domestic cat cadavers obtained from an animal shelter. Procedures: All cat cadavers were examined, and anatomic vari...

The objective of this study was to determine whether the protein Zhangfei could suppress the unfolded protein response (UPR) and growth of osteosarcoma cells. Dog (D-17) and a human (Saos-2) osteosarcoma cells were infected with adenovirus vectors expressing either Zhangfei or the control protein beta- galactosidase. We monitored cell growth as wel...

Methods: A combination of methods including computed tomography (CT) were used to diagnose a large undifferentiated sarcoma of the right mandible. A large segme...

To describe a technique for reconstruction of the rostral aspect of the muzzle of a dog after traumatic amputation. Clinical report. Adult female dog. A 6-year-old, intact, female, mixed-breed dog was admitted for facial reconstructive surgery after traumatic amputation of the rostral aspect of the muzzle. The nasal planum and the rostral portion o...

Objectives: The primary objective was to develop a repeatable radiographic technique for assessment of cranial tibial subluxation (CTS) and test the intra-observer and inter-observer repeatability of the chosen landmarks. A secondary objective was to determine the effects of digital radiographic magnification on CTS measurement repeatability. Met...

The aim of this report was to describe the clinical signs, diagnostic approach, treatment and outcome in the case of a tiger with a deformity of the paw. A 1.5-year-old tiger (Panthera tigris) was presented with lameness of the left thoracic limb. A deformity involving the first and second metacarpal bones, and a soft tissue separation between the...

Movie 2. Observe the marked improvement of the locomotion after 10 days after surgery.

Movie 1. Observe the lameness of the left thoracic limb in a tiger with ectrodactyly in the left front paw before the surgery.

For the purpose of determining factors associated with ovulation induction in rabbits, there is a need to examine the ovaries in a serial fashion. To this end, a study was designed to develop an approach that would permit serial evaluation of ovarian structures in vivo using ultrasound biomicroscopy (UBM) while preserving ovarian function in rabbit...

To determine the clinical effects of juvenile pubic symphysiodesis (JPS) treatment in hip dysplasia-prone puppies with comparison to similar untreated control puppies. Controlled clinical case study. Thirty-nine dysplastic puppies, of which six were part of the control group, with a positive Ortolani or hip distraction index (DI)≥0.40. The followin...

To measure one and two year effects of juvenile pubic symphysiodesis (JPS) in puppies defined as 'at-risk' for canine hip dysplasia (CHD) using the following objective hip conformation criteria: Acetabular angle (AA), dorsal acetabular rim angle (DARA) and hip laxity (PennHIP© distraction index (DI). Controlled clinical case study. Thirty-nine dysp...

Chronic tendinopathy injuries to the canine common calcaneal tendon are relatively common in large breed dogs and typically affect the distal portion of the tendon. In humans, poor blood supply, biomechanical faults, poor training methods and fluoroquinolone administration have all been linked with the development of Achilles tendinopathy. The most...

A chronic, partial mesenteric volvulus was found on laparotomy of an adult Bernese mountain dog with a 4-month history of intermittent vomiting, diarrhea, and weight loss. The dog had elevated cholestatic and hepatocellular leakage enzymes, increased bile acids, azotemia, isosthenuria, and a hypokalemic, hypochloremic, metabolic alkalosis. The dog...

An 8-year-old, castrated male golden retriever was referred for lethargy and inappetance. Severe pain was elicited on palpation of the left temporomandibular joint region. Computed tomography revealed aggressive bone destruction of the left bulla. Squamous cell carcinoma was diagnosed. Malignant tumor in the canine middle ear is rare.

The purpose of this study was to compare a trochlear block recession to a rotating dome trochleoplasty, a novel technique for the correction of patellar luxation in small animals. Twenty-eight limbs were used from 14 feline cadavers. With the stifles in flexion and extension, computed tomography was utilized to compare width and depth of the trochl...

To compare long-term outcomes of juvenile pubic symphysiodesis (JPS) and triple pelvic osteotomy (TPO) in dogs with hip dysplasia. Prospective clinical trial. 18 dogs with hip dysplasia (ie, distraction index > or = 0.5 in at least 1 hip joint and no, mild, or moderate radiographic evidence of degenerative joint disease [DJD]). Dogs between 4 and 5...

Osteocyte apoptosis caused by load-induced microdamage is followed by osteoclastic bone remodeling, and a causal link between apoptosis and repair has been suggested. The objectives of the present study were to use a chick model to examine the incidence of osteocyte apoptosis and the presence of osteoclasts during the first 96 hours following an os...

Peripheral quantitative Computed tomography (pQCT), a noninvasive method for measuring bone characteristics, was used to evaluate bone healing in 3 white leghorn chickens (Gallus domesticus) after radial osteotomy at 22 days of age. The time sequence for callus formation and mineralization over a 45-day period was examined by performing serial cros...
