ABSTRACT
Clinical analysis and review were made on the 65 aneurysmal patients who had intraventricular hemorrhage(IVH) confirmed on preoperative brain CT among a total of 268 patients operated on intracranial aneurysms. The study was made on aneurismal sites, the severity of IVH, postoperative ventricular dilatation and the result of treatment. The frequency of IVH among the 268 aneurysmal patients with direct clipping was 24.3%. Aneurysms originated from anterior communicating artery had the highest frequency(49.2%), followed by from posterior communicating artery(15.4%). On the severity of IVH, the frequency of severe IVH was 49.2%, the highest. The second was mild IVH, 32.3%. Forty five percent accounted for ventricular dilatation. By ventricular size index, mild dilatation was 7.7%;moderate, 13.8%;and severe dilatation, 20%. 11 patients(16.9%) undersent CSF shunting procedure. The treatment for the 65 aneurysmal patients with IVH ended in:survivor, 58 patients(98.3%), good recovery, 32.3% and 7 deaths, the rate of mortality was 10.7%.

From March 1990 to February 1992, 40 cases of lumbar spondylolisthesis underwent transpedicle fixation and fusion using VSP system and PWB system. The diagnosis were isthmic types in 17 cases(male;9, female;8) and degenerative types in 23 cases(male;5, female;18), ranging in ages from 34 to 68 years with a mean age of 52 years. The preoperative slip measured less than 20% in 11 cases, between 20 and 40% in 27 cases and more than 40% in 2 cases. At an average 19 months follow up(range;9~33months), the degree of slip correction averaged 43% in isthmic group, 51% in degenerative group, a solic fusion based on radiologic evaluation was achieved in 85%. Overall results showed 77% good, 18% fair and 5% poor. Complications included superficial infection in 2 cases, screw breakage in 1 case and screw loosening in 2 cases.

The new operative technique of ventriculotransverse sinus shunt for hydrocephalus is introduced in this paper. This method has been applied to 6 hydrocephalic patients with Pudenz-Heyer low pressure valve in our department of Kyungpook National University Hospital from June 1990 to to May 1992. 4 cases including 2 high pressure hydrocephalus of all the patients improved in neurologic deficit within 2 weeks postoperatively. 2 Cases of normal pressure hydrocephalus installed the same shunt showed no improvement without any shunt valve dysfunction, so the shunts were revised to ventriculoperitoneal shunts. The choice of transverse sinus rather than superior sagittal sinus for CSF recipient of shunt seems more reasonable anatomically and physiologically. And this procedure could first apply to the poor risk patients with local anesthesia in such cases with old age, deteriorated, and to the patients requiring revision of the other shunting. To confirm the effect and perspect for continuous using this new technique, more patients applying this method and long term follow-ups of them should be needed.
