[Diagnostic significance of percutaneous needle biopsy in metastatic neoplasms of the spine].

A retrospective review of percutaneous needle biopsy due to the vertebral metastatic neoplasms performed in 92 patients treated from 1975 to 1992 at Department of Neurosurgery, K. Marcinkowski University of Medical Sciences. Thoracic biopsies constituted 45 per cent, lumbar-32 per cent, cervical-18 per cent and sacral ones 5 per cent of all procedures. An accurate diagnosis was made in 70 per cent of all cases. The highest accuracy rate was noted in lesions compromising the entire vertebral body (84 per cent) and posterior elements of the vertebrae (89 per cent). Tomographic X-rays, CT and MRI were helpful in visualization of concomitant paravertebral mass. In these cases accuracy rate of the biopsy was 82 per cent. The technique of percutaneous biopsy and histological results were also discussed.

[Surgical management of pituitary adenomas by transsphenoidal approach].

In the years 1976-1993 we have performed 90 transsphenoidal approaches for pituitary adenomas. This paper presents a detail report concerning 23 cases, operated in the last 2 years, with CT and NMR documentation. A preoperative visual deficit was very common in this group of patients. In the postoperative period the dramatic improvement of the vision was observed in 86% of cases. In our opinion the transphenoidal approach is very useful for the operation of the tumors with suprasellar expansion.

[The management of subarachnoid hemorrhage in pregnancy].

Subarachnoid haemorrhage (SAH) from an intracranial aneurysm or arteriovenous malformation is a grave complication of pregnancy. Authors critically analyzed 12 cases of verified SAH during pregnancy from an 11 identified and 1 unidentified cerebral vascular malformation. Aneurysms were responsible for SAH in 7, and arteriovenous malformations in 4 patients. Subarachnoid haemorrhage occurred during I trimester in 2, II trimester in 3, III trimester in 6 patients and after cesarean delivery in 1 case. We conclude that the decision to operate after SAH during pregnancy should be based upon neurosurgical principles, whereas the cesarean delivery should be done in every pregnant patient with SAH.

[Spontaneous subarachnoid hemorrhage in pregnancy].

Subarachnoid haemorrhage from an intracranial aneurysm or arteriovenous malformation is a grave complication of pregnancy. The authors analyzed 11 cases of verified subarachnoid haemorrhage during pregnancy from 10 identified and 1 unidentified cerebral vascular malformation. The aneurysms were responsible for subarachnoid haemorrhage in 6, and arteriovenous malformation in 4 patients. We conclude that the decision to operate after subarachnoid haemorrhage during pregnancy should be based upon neurosurgical principles, whereas cesarean delivery should be done in every pregnant patient with subarachnoid haemorrhage.

[Conservative operative procedure in surgery of the spine].

An operative treatment within the spine due to the traumatic, neoplastic, vascular or other indications frequently result in complications as disturbance of the shape, flexibility, strength, mobility of the spine and injury of neural structures of a various degree. These complications may be prevented by minimizing surgical injury to the bone, ligaments, nerves and vessels and by adequate intra- and postoperative stabilization of the spine. The management will be effective only if the level, range and type of injury as well as spine tolerance against mechanical loads is diagnosed accurately. The authors included case reports.

Determination of the glial fibrillary acidic protein in human cerebrospinal fluid and in cyst fluid of brain tumors.

The glial fibrillary acidic protein (GFAP) have been quantitatively determined in over 200 samples of liquid content of brain tumours and in cerebrospinal fluid (CSF) of cases with various tumours of the cerebral nervous system. For establishing the GFAP value, the rocket radioimmunoelectrophoresis was used. The studies were performed in three series of patients. The GFAP value of fluids from 26 cysts of both neoplastic and non-neoplastic type had a wide range of 0.6 microgram/ml to 40 micrograms/ml. Significant elevation of GFAP was usually recorded in fluid from cysts of anaplastic tumour with astroglial differentiation. In this series of 24 cases with various brain tumours, the GFAP value of the CSF ranged from 0.2 microgram/ml to 50 micrograms/ml. In gliomas, as in astrocytoma and glioblastoma, these values were on a higher level, of over 4 micrograms/ml. In other tumours and in cerebral lesions of other aetiology, the GFAP values were lower, below 3 micrograms/ml and 0.3 microgram/ml respectively. In another series of 32 patients with brain tumour treated surgically, a significant increase of GFAP (to 30 micrograms/ml) was noted in the CSF during the first week after operation, and that was always associated with an increase of the total protein of the CSF. During the second and third week after operation, when the total protein of the CSF was reduced to a normal level, the values of GFAP were still elevated, first of all in those cases of astrocytoma and glioblastoma which were not radically excised. These findings suggest that investigation of GFAP in the CSF of patients with brain tumour may be helpful in diagnosis and prognosis.
