5 year old crossbreed dog

December 17, 2020 By Allison Zwingenberger

This week’s case is a 5-year-old female neutered crossbreed with exercise intolerance, exertional coughing, and hind limb weakness following exercise. How would you describe this dog’s radiographs? It has episodes of collapse and a PCV of 68%.

Findings

The cardiac silhouette is moderately enlarged, with increased sternal contact and a reverse-D shape on the ventrodorsal projection. The pulmonary vasculature is small in size. There is a diffuse bronchointerstitial pattern throughout the lungs. The mediastinum and pleural space are normal. The musculoskeletal structures appear normal.

Differential Diagnosis

The right heart enlargement, small vasculature, and pulmonary pattern are suggestive of pulmonary hypertension, likely due to a right to left shunt such as a patent ductus arteriosus.

Diagnosis

Echocardiography confirmed a patent ductus arteriosus and right ventricular enlargement, with pulmonary hypertension. This is consistent with Eisenmenger’s syndrome and is not surgically correctable. Phlebotomy was recommended to reduce the PCV.
