Background and purpose: The thalamic infarct is frequent among ischemic stroke. We aim to determine the frequency of the thalamic infarct and analyze the different arterial territories affected in patients with thalamic syndrome. Patients and Methods: It was a prospective study. It focused on patients hospitalized in the neurology department of our university hospital, and covered the period from January to December, 2012. Only inpatients respondents to clinical and radiological criteria for diagnosis of thalamic ischemic stroke were included. All were evaluated with detailed clinical and neuropsychological evaluation, computer tomography scan (CT scan), routine blood studies, electrocardiogram, and transthoracic echocardiography. All standard risk factors were recorded in these patients. Results: A total of 768 files were analyzed of which 219 cases of cerebral infarction were selected. Among them, 12 patients had lesions involved only thalamic nuclei, which giving the frequency of 5.48%. The mean age was 59.33 years old with a ratio sex of 1.7. The clinical signs most observed were motor deficits (8/12), speech disturbances and anterograde memory impairment (7/12), and. sensory loss (5 cases). The high blood pressure was the main risk factor in all patients. The left thalamic ischemia was most frequent with 7/12 cases. The arterial territories affected were formed by the thalamotuberal arteries in 5/12, thalamoperforating arteries, (4/12), thalamogeniculate arteries, (3/12) and posterior choroidal arteries in 2/12, giving fourteen lesions. Conclusion: Thalamic infarct solely is not so rare and all its arterial branches may be affected. The sensory deficits and abnormal involuntary movement remain the embarrassing and difficult symptom to manage.
