ABSTRACT
Three canines were identified with aberrant drainage of the caudal vena cava to the left atrium, consistent with imperforate cor triatriatum dexter, and concurrent patent foramen ovale. All three had concurrent significant pulmonic stenosis with varying degrees of hypoplasia of the right ventricular outflow tract. Echocardiography, positive contrast studies, and angiography confirmed the diagnosis. Surgical redirection of the caudal vena cava bloodflow to the right atrium was attempted unsuccessfully in two symptomatic patients. The third patient was asymptomatic, and correction was not attempted. Possible embryologic causes and possible approaches in future cases are discussed.

Displacement of the tendon of the superficial digital flexor muscle was diagnosed in 9 dogs (10 tarsi). Four of 10 displacements occurred in Shetland Sheepdogs. All dogs had an acute onset of lameness with swelling over the proximal end of the tuber calcanei. Lateral displacement occurred in 8 tarsi and medial displacement in 2 tarsi. Nonsurgical treatment (exercise restriction, bandaging, and administration of anti-inflammatory medication) was ineffective in the 5 dogs in which it was attempted. Surgical reconstruction of the supporting soft tissues resulted in return to normal function in 9 cases available for follow-up evaluation.

Cecal-colic volvulus was confirmed by surgery in two dogs. Both dogs were intact, male Great Danes. The clinical and diagnostic findings were not specific for large bowel volvulus. Clinical signs included peracute to acute onset of vomiting, mild abdominal distention and pain, lack of feces, and tenesmus. Abdominal radiographs demonstrated severe dilatation of bowel loops in both dogs. One dog survived.

A mast cell tumor in the mandibular salivary gland was diagnosed in a 9-year-old English Setter. Dense infiltrating sheets of mast cells were present within the mandibular salivary gland, the medial retropharyngeal lymph node and in two subcutaneous masses on the flank. The salivary gland, lymph node, and masses were excised. The dog was treated postoperatively with the histamine receptor antagonist, cimetidine and the alkylating agent, chlorambucil. The tumor recurred at the angle of the mandible 4 months later and the dog was killed.

Quadriceps contracture associated with a healed malunion fracture of the left femur was diagnosed in a 1-year-old cat. The proximal portion of the distal fracture piece protruded through the skin of the thigh. The protruding bone was removed surgically and the area of ulcerated skin was debrided. Because the fracture was stable and the cat was able to bear weight on the affected limb, surgical correction of the malunion was not performed. Quadriceps contracture is uncommon in the cat.

Infraspinatus muscle contracture was diagnosed in a 4 1/2-year-old female Doberman Pinscher with lameness characterized by abduction and outward rotation of the right antebrachium and carpus. After infraspinatus tenotomy, the dog recovered. This case differs from previously reported cases of infraspinatus muscle contracture because of an associated history of blunt trauma.
