RESUMO
Cervical traction has been widely used as an essential method for the treatment of cervical fracture-dislocation. This report, however, was a case in which hazardous effect of traction due to unreduced huge fragment was demonstrated only by cervical CT scan. Surprisingly plain X-rays could not demonstrated this condition. It was apparent that skeletal traction resulted in further injury of the spinal cord. Surgical removal of unreduced huge fragment was accomplished completely and interbody fusion was followed. Postoperative CT findings showed complete removal of fragment and decompression of the spinal cord as well as gratifying interbody fusion. CT scanning is imperative to evaluate the cervical fracture-dislocation and blind skeletal traction may be hazardous.

A total of 32 cases of cervical myelography via lateral c1-2 puncture using water-soluble metrizamide was evaluated. Twenty seven cases were suspected to have herniated cervical disc and five cases, spinal cord tumor. Patients were placed in prone position with head and neck slightly extended on the radiolucent operating table. Puncture was performed using 22-guage spinal puncture needle placed at the junction of the middle and posterior one-third of the bony spinal canal and 4-6mm inferior to the arch of atlas on lateral projection. The needle was positioned posterior to the spinal cord into the subarachnoid space. The author could obtain more clear images with less amount of contrast medium than doses used in conventional cervical myelography via lumbar route. The were relatively few adverse reactions and no considerable complications have been encountered with a new cervical water-soluble metrizamide myelography via C1-2 puncture.

Functional myelography, applying spinal movements(flexion-extension) in myelography, has been frequently used for accurate diagnosis of posture-related disorders such as herniated lumbar disc or spinal stenosis. Measurements were performed on functional myelographic findings of 62 patients, and in 24 cases surgically verified herniated lumber discs were present. The object of this study was to analyze changes in position and shape of the dural sac in spinal movements and confirm the clinical importance of functional myelography. The present study demonstrated that: 1) The anterior border of the dural sac was straight with flexion, but indented at the level of intervertebral space and this indentation was less prominent at L5-S1. 2) With extension, posterior indentation of the dural sac was more prominent at the level of the intervertebral space than the body, the A-P diameter of the dural sac was narrowed at all levels of the intervertebral spaces except L5-S1, and the dural sac moved anteriorly at the level of L5-S1 and all spinal bodies. 3) In surgically verified disc patients, anterior indentation of the dural sac was persistent in both flexion and extension views, and was more exaggerated with extension, but less prominent at L5-S1. In patient at L5-S1, anterior movement of the anterior dural border at the level of surgery was much decreased.

To obtain wider versatility and greater reach in microsurgical lumbar discectomy, modified procedure has been performed on 263 patients in 1979-1983. It consisted of a smaller midline incision, removal of lateral half of the spinous process, partial but sufficient microdrilling of the lamina, use of a modified slender Taylor retractor, flavotomy, preservation of epidural adipose-areolar tissue etc. Particularly a slender Taylor-Chung retractor offered yielding surgical opening and therefore secured free of pituitary forceps to every direction. The microsurgical results including 72 bisegmental and 8 trisegmental discectomies were compared with those of standard operations of same number performed by same surgeon in 1972-1979, for the good contrast. Mean blood loss per operation was 94 ml with the standard discectomy and 46 ml with microsurgery. Dural tear occured in 17 cases undergoing standard operation and in 3 undergoing microsugery. The mean time until return to duty was 8.6 weeks with standard, compared with 4.2 weeks. In the microsurgical group, 3 patients had postoperative discitis while 2 had in the standard. In this series, the results of microsurgery surpasses the standard in the convalescent phase. Major advantages of this modified microsurgical technique were its ability to secure the greater reach to remove disc material as much as possible and to preserve the integrity of normal tissue better.

Study of 22 cases with the pseudospondylolisthesis established that it occurred more frequently in the older women, and far more frequently at the L4 level, as same results as reported by others. The slipping occurred as a result of degenerative disease of the articular process and facet joint, but it never exceeded 25% in this series. This study was performed to recognize the stability of the lumbosacral joint by the measurement of the anterior and posterior vertical heights(deformity) of the body of the L5 vertebra and lumbosacral angles in our cases. We also attempted to observe whether the facet angle changes at the involved level was meaningful or not. Result : lumbosacral angles in the our patients with pseudospondylolisthesis were increased greater than normal, so lumbar lordosis was less than normal. The body of the L5 vertebra was not as wedged anteroposteriorly as it normally was. The contour of the body of the L5 vertebra resembled rectangle shape. The pedicle-facet angles were increased at involved level, but this measurement was not correctly demonstrated on the plain roentgenograms. Conclusion : The stability of the lumbosacral joint in the patients with pseudospondylolisthesis was increased due to rectangle shape of the body of the L5 vertebra and less lumbar lordosis. The pedicle-facet angles at the involved level were increased, but not correct diagnostic values.

Sturge-Weber syndrome was rare. But reported from 1860. We present a typical case of Sturge-Weber syndrome in a child and discussed the symptoms, signs, and pathological finding of various examinations in neurosurgical field such as plain x-ray, 4-vessel angiography, CT scan, EEG, IQ test, exophthamometry, opthalmometry, and fundoscopy. We find marked abnormality and asymmetry in that examination.

A series of 41 patients in a vegetative state after severe head injury in presented. The patients selected were those who were in comatose state at least 2 weeks and observed more than 6 months. The vegetative state was more common before the age of 40(75.6%). The most common types of lesion causing vegetative state were subdural hematoma and epidural hematoma(56.1%). Twentyeight patients(68.1%) had a Glasgow coma score of 3 to 5. The two most frequent complications were urinary tract infections(80.5%) and bed sores(65.9%), but the most common cause of death was respiratory complication(60.0%). CT scans taken in the vegetative state showed variable evidences of cerebral atrophy, which were considered to be the results of the injury and had little value in predicting the outcome. At 6 months, the outcome was as follows : good recovery 4(9.8%) ; moderate disability 7(17.1%) ; severe disability 12(29.3%) ; vegetative state 10(24.4%) ; and dead 8(19.5%). Twenty-three patients(56.1%) came out of the vegetative state during a 6 month follow-up period. Vegetative state is not always permanent. Therefore, it seems necessary to distinguish perisstent vegetative state from vegetative state. The term, "persistent", means that the patient, if ever, came out of the vegetative state and in the event he did he usually remained in severe disability. 15 out of the 23 improved within 2 months, 14 out of the 15 improved to at least moderate disability. 8 out of the 23 improved after 2 months but all remained in severe disability. From these results we propose that the term "persitent" be applied to patients who remain in a vegetative state for more than 2 months.

A case of huge craniopharyngioma which was removed radically is presented. A 14-year-old girl was hospitalized because of the impairment of vision and a history of generalized seizures. The computed tomogram of the brain disclosed the huge mass consisting of a large cystic part extending to the frontal base and solid part medial and posterior to the cystic. Despite of the large size and adhesion to the vital structures, the tumor was removed successfully. To remove the tumor radically, it seemed to be important not to interrupt the outer structure of the mass during dissection. The postoperative course was uneventful except transient diabetes insipidus. We report this case with brief review of the references.

The occurrence of fistulous tract between the thoracic subarachnoid space and the pleural cavity due to injury is uncommon. The one was developed after traffic accident and treated by surgical repair of the fistula : The other was post-operative complication of costotransversectomy for T2 sympathectomy. The complication was realized by the surgeon who was aware of the small leakage of cerebrospinal fluid from the dura propria of the T2 nerve root at the time of surgery. Intermittent pleural punctures for drainage and semisitting position were followed by spontaneous closure of the fistula. These cases were reported so that the uncommon condition might be added to the differential diagnosis of pleural effusion.

The purpose of this study on the surgical results for lumbar intervertebral disc herniation is to analyze the unique feature of the series which seems to be sufficient to represent Korean patients wuffering from these diseases. A total of 812 lumbar discectomies had been performed from May, 1971 to December, 1978 at Hanyang University Hospital. The most outstanding unique feature was the level of the lesion. The L4-L5 interspace was affected in 87.6%, while the most of the other series showed almost same incidence between L4-L5 and L5-S1 interspaces. The results of this analysis are as follows: 1) The incidence ratio of male to female was 1.3:1. 2) Most were in the 4th and 5th decade(53.5%). The duration was over one year in 64.6% of cases. 3) Traumatic origin was 37.8% of cases. Post-delivery, convulsive and unknown etiology were 2.2%, 0.7% and 59.3% of cases, respectively. 4) The level of the lesion was predilected at L4-L5 interspace with the incidence of 87.6%, while L5-S1 interspace was affected in 25.4% of cases. Single lesions were 70.8% and the multiple 29.2% of cases. 5) False positive findings of myelogram were 1.2% of cases. 6) Surgical results were gratifying in 92.3% of cases. 7) The incidence of postoperative complications was 3.3% of cases, which were mainly stitch abscesses. 8) The 7 our of 812 cases were associated with spinal tumors.

The ventriculoatial shunt consists of diverting the cerebrospinal fluid from one lateral ventricle to the right atrium of the heart by means of a subcutaneous valve regulated drainage system. Of the numerous drainage systems so far devised, two, Holter and Pudenz, can be cited as having received widespread acceptance. This study is a clinical investigation of the 18 cases of ventriculoatrial shunts performed at Hanyang University Hospital between May 1972 and December 1978. Of them 17 cases and the Holter System, and one the Pudenz System. Ventricular catheter tip was placed in the frontal horn and cardiac catheter tip in the upper margin of the 6th thoracic vertebra. Postoperatively immediate neurological improvement usually took place in most instances. However, four complications developed. One of them was ventricular catheter obstruction with small brain tissue particles which was removed by revision. The other ventricular catheter obstruction was the result of thickening of the cerebral mantle and reduction in size of the ventricle. This shunt was made patient again byshortening the ventricular catheter to place inside the shrunk ventricle. The third was shunt infection. In this case, the whole shunting system was removed and reapplied into a peritoneal route, after infection subsided. The last was postoperative epidural hematoma developed due to incomplete hemostasis which required emergency surgery. Shunt obstruction was said as an inevitable complication in many instances, but it may easily restored by revision. Shunt infection was also surgically amenable. Although the necessity of revision was inevitable in some instances, ventriculoatrial shunt still seemed to be the most effective method so far devised.

Cervical cordotomy via anterior approach without bone graft which is a modified Cloward's method is an effective and simple means of relieving of intractable pain with minimal destruction of bone lower morbidity and mortality. This method consists of an anterior surgical approach to the ventral surface of the cervical cord through a simple discectomy. A transverse incision in the dura mater gives excellent exposure permitting incision of the spinothalamic tracts under direct vision. For bilateral pain both incision are made at the same level of the cord without causing impairment of motor function of the lower extremities or bowel and bladder. This procedure has also many advantages and disavantages as follows ; 1. Cervical cordotomy by the this procedure has a much lower morbidity and fewer complications than the conventional procedure by laminectomy. 2. A more complete section of the spinothalamic tract is possible under direct vision. 3. A differential section of the tract with sparing of sensation in non-painful areas is possible by this procedure. 4. An incidence of the cord trauma can be minimized because the incision is possible without distorsion and traction of the cord during the operation. 5. This procedure without bone graft is simpler than original Cloward's method. 6. An water-tight closure of the dura is difficult but successful results are obtained by using a gelfoam. 7. This procedure above the level of the C3-4 interspace is difficult but possible. 8. A relief of pain below the level of the T3 dermatome is available and there is no good operative candidate when the brachial plexus is involved.
