Category: Domestic dog

Thorax

From the case: Patent Ductus Arteriosus

x-ray

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.

Case Discussion

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.
