In vitro comparison of proximal ulnar osteotomy and distal ulnar osteotomy with release of the interosseous ligament in a canine model.

Objective: To determine the effect of proximal ulnar osteotomy (PUO), distal ulnar osteotomy (DUO), and DUO with release of the interosseous ligament (DOLR) on displacement of the proximal ulna at the radioulnar joint.

Study Design: Experimental mechanical study.

Sample Population: Cadaveric, skeletally mature canine thoracic limb pairs (n=11).

Thoracoscopic subtotal pericardiectomy and right atrial mass resection in a dog.

Case Description: A 10-year-old spayed female Corgi mix was examined for a 3-week history of lethargy and weight gain.

Clinical Findings: Physical examination findings included muffled heart sounds and a distended abdomen with a fluid wave on ballottement. Thoracic radiography revealed a globoid cardiac silhouette, and thoracic ultrasonography indicated pericardial effusion and a pedunculated mass originating from the right auricle.

Proximal duodenal perforation in three dogs following deracoxib administration.

The purpose of this study was to describe the clinical and gross pathological findings, treatment, and outcome in three dogs receiving deracoxib that developed proximal duodenal perforation and subsequent septic peritonitis. Clinical findings were acute vomiting and anorexia following initiation of deracoxib therapy. Deracoxib dosages ranged from 2 to 3 mg/kg per os q 24 hours.

In vitro biomechanical comparison of polypropylene mesh, modified three-loop pulley suture pattern, and a combination for repair of distal canine achilles' tendon injuries.

Objective: To compare mechanical stability between a novel polypropylene mesh repair (Mesh), a modified 3-loop pulley suture (Suture), and a combination of the techniques (Suture+Mesh) for the repair of distal canine Achilles' tendon ruptures.

Study Design: In vitro mechanical evaluation.

Sample Population: Cadaveric canine Achilles' tendon/calcaneus units (n=34).

Retroperitoneal sarcomas in dogs: 14 cases (1992-2002).

Objective: To describe the clinical features, surgical and histologic findings, biological behavior, and outcome of dogs with retroperitoneal sarcomas.

Design: Retrospective study.

Animals: 14 dogs.

Intercostal thoracotomy closure: transcostal sutures as a less painful alternative to circumcostal suture placement.

Objective: To determine if transcostal thoracotomy closure resulted in less pain than circumcostal closure.

Study Design: Experimental cadaver and prospective clinical study.

Animals: Two canine cadavers and 13 adult, 22-29 kg dogs.

In vitro evaluation of the distribution of blood flow within a canine bipedicled latissimus dorsi muscle flap.

Objective: To identify the predominant perforating artery in the canine latissimus dorsi muscle and demonstrate that perfusion of the predominant perforating artery improves blood flow in segments of the latissimus dorsi muscle that are located distally from the thoracodorsal artery.

Sample Population: Latissimus dorsi muscles dissected from 7 dogs.

Procedures: Colored microspheres were used to determine the degree of perfusion of the latissimus dorsi muscle via the thoracodorsal artery, predominant perforating artery, or the thoracodorsal artery and predominant perforating artery together.

Medical and surgical treatment of pyothorax in dogs: 26 cases (1991-2001).

Objective: To compare outcomes of dogs with pyothorax treated medically versus surgically and to identify prognostic indicators for dogs with pyothorax.

Design: Retrospective study.

Animals: 26 dogs.
