Spontaneous pneumothorax in a dog secondary to Dirofilaria immitis infection.

A 5-year-old female spayed Labrador Retriever dog was referred to the Louisiana State University Veterinary Teaching Hospital for treatment of pneumothorax. Thoracic radiographs and computed tomography showed spontaneous pneumothorax, thoracic lymphadenopathy, pulmonary hypertension, and multifocal pulmonary bulla lesions. At surgery, numerous adult nematodes protruded from the parenchyma of the left caudal and accessory lung lobes and pulmonary arteries.

Spinal cord compression in a cat due to vertebral angiomatosis.

A 1-year-old cat was presented with general discomfort but no neurologic deficits on physical examination. An extradural spinal cord compression at the level of T10-11 and T11-12 was evident on myelography and computed tomography examination. Hemilaminectomy was performed to decompress the spinal cord.

Characterization of normal canine anterior cruciate ligament-associated synoviocytes.

This study was designed to identify and quantify synoviocyte phenotypes enveloping the canine anterior cruciate ligament (ACL) to test the hypothesis that there are at least two synoviocyte phenotypes, each with distinct quantities and topographical distributions. CD18 and HSP25 epitopes were colocalized in the synovium of 10 normal canine ACLs. Sagittal sections were prepared from medial, central, and lateral aspects of each ACL and phenotypes were quantified in the proximal, middle, and distal aspects of each section.

Repair of a coracoid luxation and a tibiotarsal fracture in a bald eagle (Haliaeetus leucocephalus).

A 4.5-kg, adult bald eagle (Haliaeetus leucocephalus) was presented after being found unable to fly. Crepitus was palpated in the left shoulder; however, the wing position was normal.

Evaluation of hemorrhage, sample size, and collateral damage for five hepatic biopsy methods in dogs.

Objectives: To compare the volume of hemorrhage, number of lobules, and portal triads available for histologic evaluation, and resultant collateral damage between 5 hepatic biopsy methods: biopsy punch, biopsy needle, ligature method, laparoscopic biopsy forceps, and ultrasonically activated scalpel (UAS).

Study Design: Experimental, repeated measures, block.

Animals: Twelve adult dogs.

Bursting tension of medium and large canine arteries sealed with ultrasonic energy or suture ligation.

Objective: To compare bursting tension of arteries > or =3 mm in diameter sealed with ultrasonic energy (UE) with arteries ligated with suture.

Study Design: Experimental, nested factorial design.

Sample Population: Vascular segments from canine cadavers.
