Management of Right Thalamic Capsular Lacunar Infarct

Immediate Triage and Admission

Patients with right thalamic capsular lacunar infarcts should be admitted to an intensive care or stroke unit with neuromonitoring capabilities for close monitoring and comprehensive treatment 2
The American Heart Association recommends transfer to a higher-level center if comprehensive care and timely neurosurgical intervention are not available locally 2
Neurosurgical consultation should be sought early, even for lacunar infarcts, to facilitate planning if the patient deteriorates 2

The American College of Radiology recommends obtaining non-contrast CT head immediately as the first-line diagnostic test, though it may be normal in up to 25% of patients initially 3
MRI with DWI/ADC sequences is superior to CT for detecting acute lacunar infarcts and should be obtained within 24-48 hours if not performed emergently 4, 5
MRI with T2 FLAIR imaging can distinguish lacunar infarcts from perivascular spaces 4, 5

The American Academy of Neurology recommends performing hourly neurological assessments using the Glasgow Coma Scale (GCS) for the first 12-24 hours, as change in GCS score within the initial 12 hours is a significant predictor of worse functional outcome at 90 days 1
Patients are at highest risk of neurological deterioration in the first 12-24 hours after infarct onset 1

The American Heart Association recommends obtaining EKG, full blood count, serum electrolytes and creatinine, fasting blood glucose and lipids 7
Doppler ultrasonography of the neck is useful for causative workup and screening for carotid or vertebral artery disease 7
Consider transcranial Doppler to provide information on patency of cerebral vessels, recanalization, and collateral pathways 7

Do not assume normal initial CT excludes significant infarction, as up to 25% may be normal initially 3
