    Intra-arterial thrombolysis in locked-in syndrome. Report of two cases
    (SOC MEDICA SANTIAGO, 2004) Mellado, P; Sandoval, P; Tevah, J; Huete, I; Castillo, L
    Locked-in syndrome is a dramatic clinical condition, the patient is can listen. and breath, but is unable to move any muscle, conserving only The vertical eye movements. The most common cause of locked-in syndrome is the thrombosis of the basilar artery and commonly leads to death, frequently due to pneumonia. Intravenous and intra arterial thrombolysis have been used successfully in a selective group of patients with ischemic stroke. There is only one report of two patients with locked-in syndrome who were treated successfuly with intra arterial thrombolysis. Other authors, based in their experiences, do not recommended this treatment. We report two female patients aged 63 and 26 years, with Locked-in syndrome due to a basilar thrombosis who were treated successfully with intra arterial thrombolysis using ecombinant tissue plasminogen activator (r-TPA). The lapses between the onset of the symptoms and thrombolysis were 5 and 8 hours respectively. A complete recanalization was obtained in both patients during the thrombolysis. One year after, the first patient has only a moderate ataxia, walking with assistance and the other has a normal neurological examination (Rev Med Chile 2004; 132: 357-60).

    Intracranial metastasis or meningioma? An uncommon clinical diagnostic dilemma
    (ELSEVIER SCIENCE INC, 2002) Tagle, P; Villanueva, P; Torrealba, G; Huete, I
    BACKGROUND Cerebral metastases are the most frequent brain tumors in adults and they may occasionally present as an isolated meningeal mass, suggesting a meningioma. Because of the prognostic relevance in discriminating both tumors, we review the literature and analyze four patients in whom the diagnosis of meningioma was initially made.

    Malignant middle cerebral artery territory infarct in one patient with bacterial meningitis
    (SOC MEDICA SANTIAGO, 2004) Lopez, M; Mellado, P; Huete, I
    The mortality of acute bacterial meningitis (BM) has remained stable in the last decades in spite of the use of new antibiotics, probably due to vascular complications. We report a 68-year-old woman with BM who had a malignant infarction of left middle cerebral artery territory 72 hours after admission to the hospital. The patient experienced a bad evolution and died four days after admission. The arterial involvement in patients with BM is explained by vasospasm of large arteries and vasculitis of small arteries. The medical treatment of a malignant middle cerebral artery infarct has a high mortality.

    Temporal crescent syndrome. Report of one case
    (SOC MEDICA SANTIAGO, 2004) Mery, V; Mellado, P; Valenzuela, R; Luco, C; Huete, I
    The temporal crescent syndrome or half-moon syndrome is a rare mono ocular retrochiasmatic visual field defect that cart be correlated to a lesion along the contralateral parieto-occipital sulcus. This field defect may be missed in automated perimetry. We report a 45 years old man, consulting for sudden loss of the peripheral temporal field in his right eye. The magnetic resonance imaging and the spectroscopy studies confirmed an ischemic lesion on the left anterior occipital cortex. Control imaging studies six months later did not show changes in the lesion.
