    Abstract: Purpose: The appropriate management of low-grade gliomas is still a matter of debate. So far, there are no randomized studies that analyze the impact of surgical resection on patient outcome. The value of the data obtained from the few retrospective reports available is often limited. Patients and methods: In the present study, we performed an analysis on data of 130 adult low-grade glioma patients. Extent of the resection was evaluated in correlation to the overall survival (OS) and progression-free survival (PFS) using Cox regression multivariate analysis. Results: Extended surgery was shown to prolong OS and PFS significantly. Re-surgery in the case of a tumor relapse has a significant impact on OS and PFS, too. Conclusions: In summary, we could retrospectively evaluate a large case series of well-defined low-grade gliomas patients with a long follow-up period showing that extended surgery would be the most effective therapy for low-grade glioma patients even in recurrent diseases.

    Notes: Summary In order to evaluate if it is practically possible to assess the volume of contused brain tissue from the CT pictures, a comparison has been carried out between the size of the cerebral contusion(s)-as estimated from the CT scans-and the post-traumatic CSF-CKBB activity, in a series of 29 patients with severe head injury. A clearance curve for the elimination of CKBB from the CSF was constructed. The relation between contusion volume and CSF-CKBB-activity was not statistically significant, while the relationships between contusion volume and outcome, and between CSF-CKBB, as estimated at 6 hours after trauma from the clearance curve, and outcome, were.

    Notes: Summary Epidermoid cysts may occur simultaneously above and below the tentorium. Eleven patients with involvement of both infra- and supra-tentorial cisterns are presented. In two cases the epidermoid, located mainly in the cerebello-pontine angle, spread into the middle cranial fossa; in three the epidermoid extended from the parasellar cisterns to the posterior cranial fossa; in six patients the epidermoid, enlarging the tentorial notch, occupied extensively both cranial fossae. The surgical approach was influenced both by the experience of the surgeon and by the main extension of the epidermoid. Total removal was feasible in two patients only but only one of the eleven patients had a recurrence of the epidermoid. The long term results appear to be unrelated to the size of the epidermoid and to the choice of approach.

    Notes: Summary The authors report a series of 37 cases of unruptured aneurysms, admitted and operated upon over a 5 year period (1985–1990), which represents an incidence of 18% of the total number of aneurysm patients operated upon during this period. These unruptured aneurysms were discovered in 4 types of circumstances: 1) Associated with a ruptured aneurysm but treated in a second procedure (9 cases); 2) After a transient ischaemic attack (6 cases); 3) After a cerebral haemorrhage of a different origin (3 cases), 4) After the onset of various neurological symptoms other than SAH (19 cases). Giant aneurysms (over 2.5 cm in diameter) are excluded from this series. Overall these 37 patients harboured 52 aneurysms, and 1 patient was operated upon on both sides. 27 aneurysms (52%) were located on the right side, 15 (29%) on the left side, and 10 (19%) on the midline. In the immediate post operative period, 1 patient died (2.6%) and 8 patients (21%) presented various complications. The outcome at 6 months was: death 2.6%, moderately disabled 8%, good recovery 89%. The arguments in favour of, or against, the surgical treatment of unruptured aneurysms are discussed in view of the literature. In favour of prophylactic surgery are: 1) The rather poor overall outcome following aneurysm rupture (including deaths before admission); 2) The rather good outcome of surgery in published series of unruptured aneurysms. The data of the natural history of the unruptured aneurysm are more questionable: in this view, surgery seems to be recommended in young patients with an easily accessible aneurysm and being in a good clinical condition. Several contra indications should be strictly accepted: severe associated diseases, age (over 65 and sometimes over 60), patient's refusal or reluctance. In cases of unruptured aneurysms to be operated upon in a second procedure after a ruptured aneurysm, the authors usually wait for 2 months or more before the second operation.

    Notes: Summary This study reports on clinical outcome in 38 patients with severe head injuries (posttraumatic coma for 6 hours or more) treated with barbiturate coma because of intracranial hypertension. Eighteen patients died, 4 patients remained in a severely disabled or a chronic vegetative state, and 16 patients reached the levels good recovery/ moderate disability. Six of these patients returned to work or school full time, 4 for half time and 3 were in a rehabilitation program. Fourteen patients were subjected to a comprehensive neuropsychological assessment. All patients except one exhibited varying degrees of cognitive dysfunction and 6 patients had signs of personality change. The quality of life for the majority of surviving patients was relatively good but the positive effects of barbiturate coma therapy in the age groups over 40 years appeared to be limited.

    Notes: Summary Between 1985 and 1990, 2056 patients with head injuries were treated in the Department of Neurosurgery at the Izmir State Hospital. Among them, 89 patients with traumatic subarachnoid haemorrhage (TSAH) were analysed retrospectively. It was noted that focal or global contusion accompanying TSAH was the most common pathology which could be detected in computer tomographic (CT) imaging. CT did not show any other intracranial lesion in 13 cases. Vasospasm developed in one patients and hydrocephalus in two others in the acute stage. Considering the relationship between the severity of a subarachnoid haemorrhage detected on CT and the mortality rate, it was seen that the mortality rate was higher in patients who suffered diffuse subarachnoid haemorrhage with intracerebral or intraventricular clots.

    Notes: Summary The records of 50 cerebellar haemorrhages were reviewed retrospectively. In this series the most important factor for clinical development, management and mortality was the presence of obstructive hydrocephalus (p〈0.01). Slowly progressive (type 1) and abruptly developing (type 2) deterioration of consciousness was significantly related to high mortality; this holds also true for the combination of hydrocephalus with an haematoma diameter 〉 3 cm. Larger haematomas had a higher mortality but this relation, analyzed alone, did not reach statistical significance (p〉0.05). In cases with hydrocephalus mortality could significantly be reduced by surgical evacuation of the haematoma (p〈0.01). The treatment of cerebellar haemorrhages must be directed at resolving obstructive hydrocephalus.

    Topics: Medicine
    Notes: Summary Out of a series of 1850 cases operated upon for lumbar disc herniation 130 underwent re-operation because of persistent or recurrent symptoms. Re-operation was successful in 62%. The prognosis of re-operation was not related to special clinical symptoms and signs but only to the operative findings. Herniations at other levels and recurrences of lumbar disc herniations had the best results (excellent in 98% respectively 54%), but scar formations alone came out much less satisfactory (only 38% excellent results). Computed tomography (CT) findings were less reliable in distinguishing between disc prolapse and fibrosis than magnet resonance imaging (MR). Therefore MR is the diagnostic method of choice in these conditions, and scar formations alone should be considered a contra-indication for re-operation.

    Notes: Summary The width of the third ventricle, the length of the anterior commissure-posterior commissure line (AC-PC line), the spatial position of the midplane of the third ventricle, and the co-ordinates of the AC, the PC, and of 17 brain targets in the thalamus, hypothalamus and pallidum, were assessed on a pre-operative Stereotactic computed-tomography (CT) study and compared to measurements on intra-operative air-ventriculography, using a non-invasive relocatable Stereotactic frame. There were no significant differences in the length of the ACPC line, in the position of the midsagittal plane of the third ventricle, or in the vertical or lateral co-ordinates of the AC, the PC and the cerebral targets, between measurements on CT and on air-ventriculography. However, the width of the third ventricle was significantly larger, and the spatial positions of both AC and PC were significantly more anterior on air-ventriculography than on the CT study. This anterior dislocation of the commissures was presumably due to the insufflation of air into the ventricles of patients being in the supine position during surgery.

    Notes: Summary Stereotactic neurosurgery requires the utmost precision. This can be achieved with modern imaging methods, provided special localisers are used which produce reference points for the calculation of stereotactic coordinates. Since not every substance can be visualised in every imaging modality, various localisera are normally used. These contain, for example, thin steel wires for CT or copper sulphate for MRI. By using a mixture of jopamidol and copper sulphate at a ratio of 1∶1, it is possible to make the reference points of a localiser visible in both CT as well as in MRI. In this way, the entire stereotactic planning can be carried out using only one single localiser. This not only simplifies the procedure, it also reduces costs.
