An 11-month-old male Miniature Poodle was found to regurgitate small volumes of fluid and food particles due to a diverticulum in the thoracic oesophagus. The diverticulum was removed surgically. Histologically the wall contained extensive scar tissue. Longterm recovery was uneventful and 5 months after surgery the dog is in good health

Relationship between apex cardiogram and left ventricular pressure events in Greyhound dogs.

Temporal relationships between the left apex cardiogram (ACG) and left ventricular and aortic pressure events were studied in 10 anesthetized Greyhound dogs. A close relationship existed between onset of the upstrokes of the ACG and left ventricular pressure. The nadir of the protosystolic upstroke of the ACG invariably occurred after the peak rate of change of left ventricular pressure increase (d/dt)LVP and the onset of aortic pressure increase, but occurred virtually simultaneously with the peak rate of change of aortic pressure increase (d/dt)A. The relationship between the protodiastolic nadir of the downstroke of left ventricular pressure and that of the ACG was close but variable. The ACG could be of value as a noninvasive examination technique in canine cardiovascular studies.

A method for indirect measurement of arterial blood pressure in the horse.

A method using the Doppler ultrasound principle for indirect determination of arterial blood pressure in the horse is described. The method is simple and suitable for field situations. Validation studies show that systolic and diastolic blood pressure measurements bear a close relationship to true values obtained by direct measurement.

The value of arterial blood pressure measurement in assessing the prognosis in equine colic.

Indirect arterial blood pressure was determined on 33 horses prior to surgical intervention for the diagnosis and/or correction of acute abdominal disorders and a relationship between low systolic blood pressure and non-survival was established. It is suggested that blood pressure determination should be used to augment other methods of clinical and laboratory examination in cases of equine colic.

Successful repair of a diaphragmatic hernia in a foal.

The diagnosis and successful surgical treatment of a diaphragmatic hernia in a 12 weeks old standardbred foal are described. The clinical syndrome in horses generally is contrasted with that seen in the foal described in this paper. Some of the factors contributing to the clinical signs are discussed.
