Plain-English summary
A 10-year-old dog was brought in for suspected laryngeal paralysis, but the vet found that the dog had no femoral pulses and a significant blood pressure difference between the front and back legs. A special imaging test called computed tomography angiography revealed a narrowing of the aorta, which is a serious condition that can affect blood flow. Fortunately, the imaging allowed the vet to see exactly where the problem was located. Treatment options would depend on the severity of the condition, and the vet would discuss the best course of action with the owner.

Abstract
Coarctation of the aorta has been described previously as either a post-mortem or angiographic finding in three dogs with clinical signs related to the aortic coarctation. A 10-year-old dog was presented for evaluation of suspected laryngeal paralysis. On physical examination, femoral pulses were absent bilaterally, with an indirect systolic blood pressure difference of 60 mmHg between the ipsilateral thoracic and pelvic limbs. Coarctation of the aorta was detected on a thoracic computed tomographic angiography study. The coarctation was pre-ductal in position, with extensive dilation of the descending thoracic aorta. Characteristic rib changes that are seen in humans with coarctation were not apparent in this dog. 3D reconstructions of the thorax provided high vascular definition with exact localization of the aortic narrowing.
