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.

A 48-year-old male patient is presented in whom huge cystic cerebellar astrocytoma simulated cerebellopontine angle tumor. Surprisingly enough, the symptoms started only 20 days prior to admission and expired before opening the dura. The neurological manifestations were of throbbing suboccipital headache, right hemiparesis, slurred speech and ataxia associated with acute increased intracranial pressure. The vertebral angiogram revealed downwardly displaced inferior posterior cerebellar artery without tumor blush. There was no evidence of increased uptake of radioactive isotope in brain scan. Suboccipital craniectomy and total laminectomy of the first and second cervical spine was performed but intradural manipulation was postponed because of tensely bulged dura, excessive bleeding and unstable vital signs to tolerate general anesthesia. The patient died of respiratory arrest 5 hours after the operation. The huge size of cystic astrocytoma on the right cerebellar hemisphere and tremendous cerebellomedullary herniation were found at the time of postmortem examination. Various pathophysiological mechanism which caused this unusual regrettable clinical outcome are briefly considered.

Interbody fusion was performed on eight cases of lumbar instability;five spondylolisthesis and three spondylolysis. Five cases were operated by anterolateral approach through the retroperitoneal space, and posterior approach on three cases after Cloward. Symptomatic improvement was obtained in almost all cases and complete fusion was observed on the roentgenogram three months later. Ambulation was possible from the immediate postoperative day without external support. While posterior approach has an advantage to observe the nerve root under direct vision, anterolateral approach has the following advantages;It is less destructive to the spinal structures, It can be performed without teasing the neural elements, anterior slipping of the vertebral body can be reduced easily, and its was applicable to the upper lumber level where neural elements qre compact. We believe interbody fusion has definite advantage to obtain strong weight bearing stability than fusion of any other parts of the spine because it has rapid recovery, low morbidity and high percentage of complete cure without disability.

27 Myelographies with Iopamidol and 27 myelographies with metrizamide were performed in order to compare adverse reactions, radiographic quality and effects on vital signs of the two contrast media after injection into the spinal subarachnoid space. Headache and nausea were less severe using Iopamidol. The most striking difference was found in adverse neurobehavioral reactions and associated electroencephalographic abnormalities which were noted in 7.4% of the metrizamide group but were not seen with the use of Iopamidol. Iopamidol was more stable than metrizamide in CSF. Image quality and diagnostic accuracy of Iopamidol myelography was equivalent to metrizamide for intrathecal application.

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.

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.

It is the fact that parenteral antobiotics have no place in the treatment of the discitis after postoperative state because the antobiotics can not reach the focus of infection on account of the avascular zone of the intervetebral space. The author treats more extensive discitis to place an indwelling rubber catheter into the cavity to a contunuous irrigation with normal saline solution containing antobiotics. The catheter is left are as following ; 1. It is to effect the continuous direct administration of the antobiotics. 2. It is a mechnical effect by flushing out necrotic particles. 3. It is less recurrent infection. 4. The method is very simple, inexpensive. 5. The treated period is very short in contrast with immobilization and systemic antibacterial administration.

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.

Ewing's sarcoma is an uncommon malignant neoplasm of the bone, which is rather infrequent in childhood and represented only 2% of all neoplasm under the age of 15 years. Clinical picture was that of progressive paraplegia associated with localized pain. The authors have experienced a case of primary Ewing's sarcoma of the first and second lumbar vertebrae in a 26-year-old male.

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.
