Aprotinin is a serine protease inhibitor that improves the hemostatic function and modulates the anti-inflammatory responses. Recently, aprotinin has been widely used in various surgical procedures including open heart surgery. One of the complications of aprotinin is anaphylactic reaction and the incidence increases with re-exposure. We experienced a case of anaphylactic reaction in a 5-year-old female during open heart surgery. After cardiopulmonary bypass weaning, during aprotinin i.v. infusion for reducing blood loss, sudden hypotension and bradycardia occurred. After re-institution of CPB, the patient recovered. In the post-operative review of the chart and patient, we found that this patient had been exposed to aprotinin 20 days ago. In conclusion, we recommend some preventable methods for anaphylaxis of aprotinin; aprotinin should be used after a skin test or i.v. infusion test and used by mixing with CPB priming solution.

Mayer-Rokitansky-Kster-Hauser Syndrome is characterized by the absence of the vagina and uterus, the presence of apparently normal tubes and ovaries, feminine appeara-nce, normal female secondary sexual characteristics, a normal 46,XX karyotype, and a fem-inine psychosexual orientation. Various methods of surgical treatment have been introduced, but the ideal method is still not found. The two cases reviewed in this paper were all treated with McIndoe operation using full thickness skin graft. Both women were satisfied with vaginal depth and excellent result was achieved. We report two vaginoplasties in patients of Mayer-Rokitansky-Kster-Hauser Syndr- ome including a brief review of literature.

Total laminectomy for the removal of intradural-extramedullary spinal cord tumors has been used widely, but postoperative complications often develop, such as kyphosis, spinal instability, and persistent back pain. In this study, we evaluated seven patients with intradural-extramedullary spinal cord tumors with respect to the value of unilateral limited laminectomy. Our cases included six schwannomas, and one meningioma. The cervical region was involved in four cases, the thoracolumbar region in two cases, and the lumbar region in one case. The rationale for choosing a unilateral approach is to preserve musculoligamentous attachments and posterior bony elements as much as possible. The patients were mobilized on the third postoperative day and preoperative neurological symptoms were recovered within a few weeks. We did not observe any complication relating to unilateral limited laminectomy and at follow-up evaluation (at 3 and 12 months postoperatively), none of the patients showed spinal deformity or spinal instability. We think that the unilateral limited laminectomy is a safe and efficient technique for the treatment of intradural-extramedullary spinal cord tumors. We suggest that this technique is one of the best treatments for these tumors.

PURPOSE: We analyzed the relationship between MRI patterns and neurologic outcome and explored the effectiveness of MRI as a tool for predicting the outcome. METHODS: We analyzed 23 full term infants with severe HIE retrospectively who were admitted to our NICU from Sep. 1993 to May 1998. Their MRI findings were classified into 4 patterns : type I : deep gray matter injury; type II : cortical, subcortical white matter injury; type III : localized periventricular white matter injury; and type IV : mixed injury. Neurodevelopmental outcome was assessed at a mean age of 30.7 months and the patients were grouped in two - neurodevelopmentally normal(8 cases) and delayed(15 cases, including 4 deaths). RESULTS: All type I patients(n=3) showed severe neurodevelopmental delay. Of seven type II patients, three developed normally(42.9%) and four showed developmental delay(57.1%). All type III patients(n=4) developed normally(P=0.008). Of nine type IV patients, one(11.1%) developed normally and eight(88.9%) showed severe developmental delay. There were twelve patients with lesions including thalamus and basal ganglia injury in MRI(type I+IV) and most of them(n=11, 91.7%) were severely developmentally delayed(P=0.002). Acute total asphyxic insult was documented in 9 of the 23 infants, 8 of 9(88.9%) had patterns of lesions including thalamus and basal ganglia injury. The neurologic outcome was poor for all except one of these patients. CONCLUSION: All the patients with periventricular white matter injury in MRI developed normally whereas all except one patient with subcortical gray matter injury showed severe neurodevelopmental delay. The patterns of brain injury shown in the MRIs of term infants with severe HIE provided significant information about the prognosis for the neurodevelopmental outcome of these infants.

Primitive neuroectodermal tumor (PNET) occuring in the brain (especially in the cereburm) of young individuals is a rare and highly malignant neoplasm. The authors analyzed 5 cases of primitive neuroectodermal tumor, operated from January 1986 to September 1987. They had characteristic clinical, radiologic and pathologic features. Patient's age ranged from 2 years to 14 years old (mean 8.2 years old) and there were 3 boys and 2 girls. They were rapidly growing tumor, with a brief duration of symptoms taking a rapidly progessive course. Computerized tomographic findings were characteristic, revealing the large, irregular, typically iso-to hyper-dense mass lesions with calcification and cystic or necrotic areas, and showing dense heterogeneous contrast enhancement of the mass in the cerebral hemisphere. Grossly all of the 5 cases showed hemorrhage and necrosis with sharp border and 2 cases showed calcification and cystic change grossly. Microscopically, they were predominantly composed of undifferentiated small dark cells with evidence of focal differentiation along glial and or neuronal lines. Four cases showed glial differentiation and three cases showed neuronal differentiation. Mesenchymal components were predominant in 3 cases.

Primary intracranial hemangiopericytoma is rare and resemble meningioma on imaging study. It shows meningeal attachment, and is usually isointense with gray matter on T1-weighted MR image with heterogeneous enhancement and prominent vascular flow voids on T2-weighted image. Cystic type of hemangiopericytoma is very rare and only 3 cases have been reported in the literature which arised in the middle fossa, cerebellum, and occipital area. Ventricular hemangiopericytomas were reported in 9 cases, and all of them were solid type. Authors experienced a peculiar case of cystic hemangiopericytoma in the 3rd ventricle and report it with review of the literature.

OBJECTIVE: The incidence of aneurysmal subarachnoid hemorrhage has been increasing. At the same time, surgical results for elderly patients are unsatisfactory and no guidelines of treatment are available. We carried out a study comparing variable factors and surgical results between young and old age groups to find ways to improve prognosis. METHODS: A retrospective study was carried out on 754 patients who were operated on between 1990 and 2004 by the same surgeon in our hospital. The patients were divided into seven groups according to age: 93 patients below 40 years of age (Group I), 419 patients aged 40~59 (Group II), 115 patients aged 60~64 (Group III), 82 patients aged 65~69 (Group IV), 28 patients aged 70~74 (Group V), 12 patients aged 75~79 (Group VI) and 5 patients over the age of 80 (Group VII). We then checked their medical history, Fisher's grade, Hunt-Hess grade, postoperative complications, and Glasgow Outcome Scale. RESULTS: Age was not a statistically significant factor among patients below 70 years of age (P value> or =0.05). But for those aged 70 and older, the age factor had a statistical value (P value< or =0.001). In addition, there was a close correlation between Hunt-Hess grade IV and V patients, and those with vasospasm, and hydrocephalus after surgery, with poor prognosis in elderly patients as well as young patients (P value< or =0.001). CONCLUSION: Advanced age (under the age of 70) dose not precluded adequate surgical treatment in patient with AN SAH, and we should be also alert to preventable causes of delayed neurological deterioration for improving the outcome in all elderly groups.
