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.

OBJECTIVE: Arachnoid cysts (ACs) can be cured by making the definite and wide communication between the cyst and arachnoid space using endoscopy, but often it is impossible only through the usual working-channel (intra-channel) procedures. We discuss and propose a more valuable endoscopic technique with the presentation of our series of cases. METHODS: We treated 9 patients with cortical AC in various locations with extra-channel endoscopic techniques. The patients ranged in age from 3 years to 60 years (mean age, 37.2 yrs). The follow-up period ranged from 12 to 26 months (mean follow-up duration, 17.2 months). All patients had large AC compressing the adjacent brain with clinical symptoms or signs. The authors performed extensive fenestration via single burr hole with the aid of endoscope. Being bypassed the rigid endoscope, through the space between the shaft of endoscope and guiding cannula (extra-channel method), fenestration procedures were done in the dry fields. RESULTS: Eight (88.9%) patients had been treated successfully with endoscope. One patient required shunt procedure. Among the eight patients who were treated with endoscopic procedure, 6 patients (66.7%) showed cyst reduction, and two (22.2%) showed disappearance of cyst. CONCLUSION: We suggest that extra-channel method will be simple and easy to perform using more valuable instruments with wider working area, and may promise better results compared to the conventional intra-channel endoscopic procedures.

Carcinoembryonic antigen(CEA) in blood and CSF was reported to be increased in cases of nervous system neoplasms by some investigators. To evaluate the oncological diagnostic value of CEA in the neurosurgical conditions, this study has been performed on 24 nervous system neoplasms and 8 non-nervous system as well as 49 controls. In addition, alpha-fetoprotein was also measured on the same conditions because of its close oncologic nature and recent diagnostic application on the general surgical conditions. The CEA concentration in blood and CSF were determined by CEA Radioimmunoassay kit, and the alpha-fetoprotein in blood and CSF were determined by GammaDab kit. The result showed that concentration of CEA and alpha-fetoprotein was higher and seemed to diagnostic in Extra-CNS neoplasma. In nerovous system, however, these were the lower than we expected, although were higher than control. Moreever, these levels were not unique on same oncologic condition and rather somewhat variable. From these results, increased concentration of these itself may be considered suggestive of existence of nervous system neoplasm, but it does mean neither degree of malignancy nor its origin.

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.

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.

The authors experienced on the use of bovine bone in 3 cases of interbody fusion employing the Cloward technique. Two patients were cervical fracture-dislocation and one patient was a case of lumbar spondylolysis. With use of bovine bone, iliac osteotomy is unnecessary, and this procedure is no problem of donor site pain and infection which can be possible in interbody fusion with iliac bone and rib graft. With the use of bovine bone the additional advantages are. 1) The operative procedure is simplified. 2) The time required for the operation is diminished. 3) Patient meralgia is eliminated completely. 4) The surgeon can have uniformly sized bones of a proven hardness on hand. 5) The epidural bleeding is showed through lattice of bovine bone.

The mean values of the height, depth and lateral shifting of the spinous processes and the height of the intervertebral disc spaces of 100 patients were measured in the lumbar region. The application of microsurgical techniques in the operation for lumbar disc herniation clearly reduced the overall surgical trauma suffered by patient, but the spinous process might disturb the insertional course and multidirectional activities of the pituitary forceps due to a very small skin incision. The purpose of this study was to prove the relationships between intervertebral disc space and spinous process in the lumbar region. The results were as follows; 1) The height of the intervertebral disc space from L3-4 to L5-S1 intervertebral disc space was 12.63mm, 12.57mm and 11.71mm respectively. 2) The depth of the spinous process from L3 to L5 was 28.87mm, 27.87mm and 23.97mm respectively. 3) The lateral shifting of the spinous process from midline to the right side was 4.39mm, 4.35mm and 4.01mm at L3, L4 and L5 spinous process respectively and to the left side was 3.61mm, 3.70mm and 3.69mm at L3, L4 and L5 spinous process respectively. Conclusively, the lower part of the spinous process was overlapped above the intervertebral disc space at L3-4, L4-5 and L5-S1 intervertebral disc space. About 4mm of the lateral shifting of the spinous process was protruded to both right and left side in the insertional course(about 2-3cm) of the pituitary forceps. The spinous process might disturb the multidirectional activities and perpendicular insertion of the pituitary forceps. So, the removal of the spinous process to the midline was recommended to perform the complete removal of disc materials in microlumbar discectomy.

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.

We analysed ultrasonic findings of 54 brain scan cases(45 cases were performed through the anterior fontanelle and the temporoparietal thin bone and 9 through the surgical bone defect) and comparison of these pictures with those obtained in the same patients by CT scan showed prominent correlation. Ultrasonography was more sensitive to different histologic features and provided a more accurate depiction of the neuropathologic characteristics in most of cases. We conclude that ultrasonography of the brain was proven to be quite useful in the screening and follow up of neonates and infants under 15 months of age, and as a follow up method in post operative patients. It was also more accurate than CT scan in cases of abscesses and cystic lesions.
