Abstract

Abstract: This research was conducted to describe computed tomographic angiography (CTA) diagnosis and surgical treatment in two vascular ring anomaly (VRA) dogs. Using CTA to confirm VRA before surgery,which was left 4th intercostal thoracotomy for ligaturing the ligamentum arteriosum. Case 1 was followed by esophageal balloon dilatation. CTA confirmed persistent right aortic arch (PRAA) in both dogs and also revealed other vascular anomalies, ectopic origin of the right carotid artery and persistent left cranial vena cava, respectively. After surgery, the esophageal stenosis was fully corrected, and regurgitation was disappeared. CTA can be used in diagnosis of VRA more accurately, which is of benefit to surgical plan. The surgical treatment for PRAA is effective in dogs.

Key words: vascular ring anomaly, persistent right aortic arch, ectopic origin of the right carotid artery, persistent left cranial vena cava, CT angiography, thoracotomy
