英文摘要 | There are various clinical manifestations of thalamic hemorrhage (TH). The aim of this study was to correlate the clinical manifestations of TH with the topographic subtypes. We retrospectively studied 114 patients with TH. Clinical data included age, sex, risk factors, neurologic manifestations (symptoms and signs at onset, Glasgow coma scale, motor and sensory disturbance, ocular signs, and neurobehavioral defects), and outcome. Based on the findings of computed tomography (CT), the patients with TH were classified with small and large hematoma, and were divided into nine subtypes according to topography. All patients with posterolateral TH had motor deficits, and half of those had sensory deficits. Patients with anterolateral TH were characterized by confusion, motor and ocular deficits. All patients with medial TH tended to have disturbed consciousness. Patients with dorsal TH presented with minimal and transient sensorimotor disturbances. Patients with mixed TH showed variable deficits due to the involvement of various areas in the thalamus. Thalamic-capsular hemorrhage occurred in 53 patients: all had motor deficits. Oculomotor disturbances and severe motor deficits were found in patients with thalamic-mesencephalic hemorrhage. Thalamic-capsular-nuclear hemorrhage revealed motor and other (sensory, consciousness, ocular or neurobehavioral) disturbances. Poor prognoses were found in patients with extensive thalamic hemorrhage presenting as coma. Hypertension was the major risk factor of thalamic hemorrhage. Factors causing poor prognoses included impaired consciousness, large hematoma, and intraventricular hemorrhage. |
