안용붕,이종수,이상열,이승재,박효일 대한신경외과학회 1992 Journal of Korean neurosurgical society Vol.21 No.2

This review of high cervical spine injuries includes patients admitted to Paik Hospital, Seoul during the period 1981 to 1990. 250 patients had cervical fractures of instability. 42 had involvement of the high cervical spinal column and 13 had neurological deficits. 20 had odontoid fracture. Patients with combination C1-2 fracture-subluxation injuries should be studied with thin section computed tomogram of conventional tomogram. Appropriate treatment is determined by the type of axis fracture and includes sugical and nonsurgical stretegies. An experience with 42 patients with high cervical fracture and dislocation is presented and management and follow-up guidelines are reviewed.

Bilateral hypoplasia of the internal carotid arteries is a rare condition. The authors experienced two cases of bilateral hypoplasia of the internal carotid arteries. In one case a 46-year-old female patient presented with subarachnoid hemorrhage Internal carotid angiograms showed right hypoplastic internal carotid artery and left agenetic internal carotid artery. An aneurysm believed to he the source of the subarachnoid hemorrhage, took origin from the trunk of the basilar artery. In another case a 48-year-old male, presented with semicomatous mentality. Brain CT demonstrated intracranial hemorrhage on the parasylvian area, and high density on the basal cistern, quadrigeminal cistern and temporal horn of left lateral ventricle. Initially aortic arch injection did not visualized the origin of the common carotid arteries. It revealed only the vertebral arteries and both external carotid artery originating from each vertebral artery. A selective left vetebral artery study demonstrated a communication between the hypertrophied basilar artery and the posterior cerebral arteries. The anterior and middle cerebral vessels, in turn, were opacified through the circle of Wiliis. via the posterior communicating arteries. In addition, an aneurysm, believed to be the sourse of the subarachnoid hemorrhage took origin from the posterior cerebral artery. The cases of the bilateral hypoplasia of internal carotid artery with intracranial aneurysm are reported as above, together with literature review.

The present study was attempted to obtain the regional differences of development of the parvalbumin- and calbindin-ir neurons in the maturing rat hippocampus. Sprague-Dawley rats at 3, 7 days, 2, 3, 4, 5, 6, and 9 weeks of age were transcardially perfused with 4% paraformaldehyde fixative. The hippocampus was cut into 30 or 40㎛ sections with a cryostat. Immunohistochemical staining was performed for the parvalbumin and the calbindin using ABC method. The parvalbumin-ir neurons and their axon plexuses acheived the adult patterns as following sequences, CA2 and CA3 at the second postnatal week, CA1 at the third week, and dentate granule cell layer by fifth postnatal week. In addition, the calbindin-ir neurons showed the adult patterns by second postnatal week in CA2, CA3, mossy fibers, and the molecular layer of the dentate gyrus, the CA1 at the third week, and finally the dentate granular cell layer by fifih week. These results revealed that time course of the maturation of the parvalbumin- and calbindin-ir neurons in the rat hippocampus showed an area-specificity. The delayed maturation of CA1 and the latest maturation of the dentate granular cell layer suggested that the neurons in these locations seemed to exhibit differential responses to the conditions of increased intracellular calcium, when compared with other areas or with the adult hippocampus.

We have analysed 11 1 cases of subdural hygroma that were developed after various neurosur gical conditions including head injuries. The results were summarized as follows. 1) The peak incidence was the age of 50's and mured most frequently in male. 2) Causes were head injuries(91 cases), traumatic intracranial hematoma removal(l0 cases), operation for intracranial aneurysms(4 cases), hypertensive intraerebral hemorrhage evacuation (2 cases), ventriculoperitoneal shunt(2 cases), brain tumor removal(1 case), arachnoid cyst excision( 1 case), and cerebral infarction(1 case). 3) Acute subdural hematoma was most often associated with complex subdural hygroma. 4) Clinical manifestations were headache, altered mental state, disorientation, nausea in order. 5) Operations were underwent in 27 cases and surgical complications were reaccumulation and pneumocephalus in order. 6) Mortality rate was 6.3%. 7) The prognosis of the simple hygroma was very good, but the complex was not.

The authors analyzed the radiographs(brain CT and cerebral angiograms) and medical & surgical records of 54 cases of ruptured anterior communicating artery aneurysms resulted in operations at our hospital from January 1991 to December 1995. The results were summarized as follows : 1) The rate of incidence was found to be highest in sixth decade and the ratio of male to female was 1 : 1 2) On the preoperative brain CT, ventricular or cerebral hemorrhage combined cases had high Hunt-Hess and Fisher grades. 3) Of 54 cases, hypertension was observed in 20 cases(37%). Hypertension had no effect on the admission Hunt-Hess and Fisher grades. 4) Classification of the anterior communicating artery aneurysms according to its directions were as follows : anterior direction in 57.4%, superior direction in 18.5%, posterior direction in 13%, inferior direction in 11.1%. 5) The afferent artery of anterior communicating artery aneurysms were as follows ; left A1 in 38 cases(70.4%), right A1 in 12 cases (22.2%), bilateral A1 in 4 cases(7.4%). 6) The ranges of diameters of the aneurysm was as follows ; 6~10mm in 57.4%, below 5mm in 22.2%. 7) The posteriorly directing aneurysms showed less favorable preoperative state, and preoperative hydrocephalus was most common on the posteriorly directing aneurysms. 8) There was no significant relationship between direction of aneurysm and prognosis. However, better Hunt-Hess grades seem to correlate better prognosis. 9) The operation was performed by pterional approach in all cases, the approach side was selected for the presence of dominant feeding artery in 50 cases(92.6%). 10) Overall mortality rats was 14.8%, the patients who died are of the older age group and the cause of death was medical complication in 6 cases.

Recently we experienced a soft tissue sarcoma originated in the spinal epidural space at upper sacral area and extending into intrapelvic area in a young male patient. It was diagnosed primary Ewing's sarcoma histologically. Ewing's sarcoma is usually found in long bones. But rarely discovered in an extraosseous area. So spinal epidural Ewing's sarcoma is rare to be found. Only 6 cases were reported in the English literature until 1986. We present the case with review of literatures.

A series of 4 patients with aneurysm of distal anterior cerebral artery(DACA). operated with microtechniques, is reviewed. Because the incidence of aneurysms in this location was only 2 to 4% of that of total aneurysm, little expericences on surgical management of this aneurysm have been reported. An aneurysm in this location is difficult to approach surgically because of their multiplicity, characteristically broad and sclerotic base, with small subarachnoid space in the interhemispheric fissure. We surgically treated DACA aneurysms of 4 cases through the interhemispheric approach via the unilateral frontal paramedian craniotomy on the nondominant side.
