PURPOSE To describe the causes of infantile lenticulostriate vasculopathy (LSV) as demonstrated by sonography and propose the pathogenesis of these findings. METHODS Five hundred eighty-six infants were examined via echoencephalography because of seizures, psychomotor retardation, dysmorphism, congenital malformation, microcephaly, macrocephaly, bulging(More)
Twelve children with type 1 herpes simplex encephalitis (3 with relapse, 9 without) have been monitored during the past 7 years. Ten of the children received intravenous infusion of acyclovir (30 mg/kg/day) for 10 days, 1 child who experienced relapse received 15 mg/kg/day, and another relapsed child received no antiviral agents until relapse. Relapse(More)
Solitary cerebellar metastatic tumors are rarely reported in the literature. We reviewed 240 posterior fossa tumors treated in the past eight years. There were 11 cases of solitary metastases in the cerebellum. The primary tumor was lung cancer in five cases and breast carcinoma in two cases; the remaining three cases had colon cancer, nasopharyngeal(More)
From January 1990 to December 1995, a total of nine cases of Moyamoya disease were treated at the National Taiwan University Hospital with combined encephalo-arterio-synangiosis (EAS) and encephalo-myo-synangiosis (EMS). There were five males and four females and their ages ranged from 6 months to 31 years. Of these, two cases had their first symptom as(More)
The brainstem abscess of a nine-year-old girl with tetralogy of Fallot was cured after six weeks of parenteral antibiotic therapy, without surgical intervention. Serial studies of brainstem auditory evoked potentials were undertaken until the patient was clinically normal. To the authors' knowledge, this is only the second medically cured case reported in(More)
We treated a neonatal infant who presented with heart failure and a giant torcular dural arteriovenous fistula by staged transtorcular embolization with two guidewires, 95 platinum microcoils, and tissue glues through a needle-size craniotomy. Blood loss was minimal. The patient was stable without heart failure after a three-staged embolization. The lesion(More)
Usually, a transtemporal Doppler sonographic study of the anterior cerebral artery can insonate the A1 segment only. We found a new window just above the supraorbital ridge to approach the A2 segment and even the proximal portion of the pericallosal segment in 17 of 21 volunteers aged from 16 months to 39 years. The failed four cases had an average age of(More)
To verify the optimal hematocrit (Hct) level in the treatment of cerebral ischemia, cerebral oxygen transport (CTO2) and cerebral oxygen metabolism (CMRO2) in graded isovolemic hemodilution were evaluated during cerebral ischemia. Isovolemic hemodilution with low molecular weight dextran to stepwise lower Hct from 43% to 36%, 31%, and 26% was carried out in(More)
Treatment with 3-(2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid (CPP), a potent and competitive N-methyl-D-aspartate antagonist, is able to reduce the hypoxia-induced increase in striatal dopamine level by 26% even after the hypoxic insult has occurred. The hypoxia-induced decrease of the striatal 3,4-dihydroxyphenylacetic acid level can also be(More)
Thirty-five patients (27 men and eight women) who met our criteria of case selection for percutaneous lumbar discectomy (PLD) were treated by this method during the period May 1992 to June 1993. Thirty-six spaces, including one man with double disc disease, were decompressed. Patients ranged in age from 14 to 64 years. All patients but one were followed up(More)
