Surgical resection of a left auricular aneurysm in a dog

2019

Aneurysmal dilation of the atrial appendage (auricle) is rare in humans and dogs. Congenital and acquired etiologies are hypothesized. Although right auricular aneurysm has been described in dogs, this is the first case report of an aneurysm of the left auricle of a dog with an intact pericardium. In humans, because complications of arrhythmia and thromboembolic disease have been reported, surgical resection of left auricular aneurysm is recommended. This report describes the successful surgical resection of a left auricular aneurysm in a dog, including a one-year follow up. Surgical resection can be considered in dogs with auricular aneurysm.
