Abstract

Persistent left cranial vena cava (PLCVC) is a remnant vessel connected with the coronary sinus and draining into the right atrium. A 3-month-old intact male Bichon Frise was evaluated for the presence of a mechanical murmur auscultation in the local animal hospital. No significant clinical signs were present on physical examination except mechanical murmur. Patent ductus arteriosus (PDA) was diagnosed in the imaging procedure. During the left thoracotomy, PLCVC was found. The vascular malformation made the surgical process difficult by hiding PDA from the left thoracotomy surgical view. PLCVC and the vagus nerve was carefully dissected and lifted to secure a clear surgical view of PDA. The ductus arteriosus was ligated. Computed tomography angiography (CTA) was performed postoperatively. On CTA, left brachiocephalic vein retaining connection with the coronary sinus draining into the right atrium was observed. CTA is highly recommended for dogs with PDA to provide better postoperative results.
