Medical records of eight dogs presenting with acute onset of neurological signs and a diagnosis of brain infarction as determined by computed tomography (CT) imaging were reviewed.
Retrospective single-centre case review.
Ischaemic infarction in the territory of the rostral cerebellar artery was identified in three spaniel-breed dogs. All cerebellar infarcts were non-haemorrhagic. Telencephalic infarcts were identified in five dogs, in the territories of the middle cerebral artery (2/5) and rostral cerebral artery (3/5). One of these dogs had an ischaemic infarction, but all other infarctions appeared haemorrhagic. All dogs were geriatric (≥ 8 years old), with concurrent medical conditions identified in six dogs. One dog was euthanased after diagnosis because of the severity of its neurological signs and one dog was euthanased as a result of associated renal disease 2 months after diagnosis. Six dogs were alive at least 1 year after diagnosis.
CT is useful in the diagnosis of cerebrovascular accident in dogs, which can present as a spectrum of images with early changes in attenuation and subtle mass effects detected after infarction. CT is particularly sensitive for detecting haemorrhagic infarction, but under-represent ischaemic and lacunar infarctions when compared with MRI.
回顾8只出现急性神经症状且经计算机断层扫描（CT）成像确诊为脑梗死的犬的病历。
回顾性单中心病例回顾。
在3只西班牙猎犬品种的犬中发现了小脑前动脉供血区域的缺血性梗死。所有小脑梗死均为非出血性。在5只犬中发现了大脑梗死，分别位于大脑中动脉（2/5）和大脑前动脉（3/5）供血区域。其中1只犬为缺血性梗死，但其他所有梗死均表现为出血性。所有犬均为老年犬（≥8岁），6只犬伴有其他疾病。1只犬因神经症状严重在诊断后实施安乐死，1只犬在诊断后2个月因相关肾病实施安乐死。6只犬在诊断后存活至少1年。
CT对犬脑血管意外的诊断有用，其可呈现一系列图像，在梗死后可检测到早期密度变化和轻微占位效应。CT对检测出血性梗死特别敏感，但与MRI相比，对缺血性和腔隙性梗死的显示不足。
