Plain-English summary
A 12-year-old neutered male Chihuahua was brought in after showing signs of a stroke due to a brain infarction in the right side of his brain. Doctors used a special ultrasound technique called transcranial Doppler ultrasonography to check blood flow in his brain. Initially, blood flow was lower on the affected side, but after treatment, the blood flow improved, and the dog's neurological symptoms got better. This method proved to be a helpful way to monitor his condition without invasive procedures.

Abstract
A 12-year-old neutered male Chihuahua was diagnosed with acute brain infarction in the right middle cerebral artery (MCA) territory. Transcranial Doppler ultrasonography (TCD) was performed to assess the local cerebral blood flow at the time of diagnosis and after 4 and 31 hr. Initially, the right MCA retained blood flow but with a lower cerebral blood flow velocity (CBFV; 14.9 cm/sec) than the left MCA (27.9 cm/sec). The TCD vascular resistance variables were higher in the right than in the left MCA. An increase in the CBFV and a decrease in TCD vascular resistance variables were observed, consistent with improvements in neurological symptoms. TCD can be a non-invasive, and easy-to-use modality for bedside monitoring of cerebral edema and infarction.
