Object : To treat hydrocephalus by ventriculo-peritoneal shunt operation, the correct positioning of the proximal catheter in the ventricle is very important. The purpose of this study was to develop the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle in the ventriculo-peritoneal shunt operation. Materials and Methods: The "shunt guiding kit" is made of tungsten alloy and it consists of one frame, two screws and one guider. Through the guider, the proximal shunt catheter operates by mechanically coupling the posterior burr hole to the anterior target point. Results: We have treated three hydrocephalus patients with use of the "shunt guiding kit", and achieved good location of proximal shunt catheters. Conclusion: We developed the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle, and this would be very useful for preventing ventriculo-peritoneal shunt malfunction and preventing possible brain injury during the procedures.

Major cause of aqueductal stenosis has been known as obstruction due to gliosis, forking, and septum formation. But with recent advances of neuroimaging techniques such as high resolution CT or MRI, a small tumor surrounding aqueduct has been found increasingly as a cause of aqueductal stenosis. We report four cases of quadrigeminal plate tumor causing aqueductal stenosis. In one case, tumor was removed via transtentorial approach, which showed benign astrocytoma. Hydrocephalus was treated with ventriculoperitoneal shunt in 2 cases and endoscopic 3rd ventriculostomy in other 2 cases.

79 patients with anaplastic astrocytoma or glioblastoma multiforme were treated at the Department of Neurosurgery. Yonsei University, College of Medicine between 1977 and 1990. First group with 41 patients were treated with surgical resection, irradiation and intra-arterial chemotherapy with ACNU. The other group was 38 patients who were treated by radiotherapy after surgical resection. ACNU was given in doses of 2㎎/㎏ before postoperative radiotherapy and was repeated at the interval of 8 weeks. Intra-arterial administration was performed over a period of 5 minutes through percutaneous selective catheterization into the internal carotid artery at lesion side or vertebral artery. No significant complication was noted during intra-arterial ACNU administration. Survival rates were analyzed between two groups and several prognostic factors were analyzed in ACNU group. Survival curves were observed according to Kaplan-Meier method or life-table method. ACNU therapy showed good results in some patients but was not stastistically significant effects in general. Much longer follow-up could probably change outcome in ACNU group. But total resection subgroup in unilateral location was survived statistically significantly longer than subtotal resection subgroup in the ACNU treated group(p<0.01).
