RESUMEN
INTRODUCTION: Thromboembolism is one of the most serious complications associated with coil embolization therapy. AIM: To identify predisposing factors for thromboembolic complications, as well as to determine whether thromboembolism has an impact on clinical outcome. MATERIAL AND METHODS: From February 2008 to March 2015, 273 consecutive patients were treated at our institution via endovascular coil embolization. Patient medical records were reviewed with an emphasis on procedure description, potential risk factors and clinical outcomes related to thromboembolism. Thromboembolic incidents occurred in 19 (6.9%) cases. Multivariate logistic regression models were used to determine independent predictors of thromboembolism. Clinical outcome was analyzed using the Glasgow Outcome Scale (GOS). RESULTS: Multivariate analysis showed that subarachnoid hemorrhage was an independent risk factor for thromboembolic complications (p = 0.003; OR = 4.4; 95% CI: 1.67-12.02). The difference in frequency of perioperative mortality (GOS 1) in patients with thromboembolism and without thromboembolism was not statistically significant (p = 0.22). The differences in frequencies of severe disability (GOS 2-3) and moderate to low disability (GOS 4-5) between patients with thromboembolism and without thromboembolism were statistically significant in the general study population (p < 0.05). CONCLUSIONS: Subarachnoid hemorrhage is an independent predictor of thromboembolic complications associated with endovascular coiling of cerebral aneurysms. Thromboembolism is associated with significantly increased risk of morbidity, and it affects to a certain extent the periprocedural mortality.
RESUMEN
BACKGROUND AND PURPOSE: The aim of the work was a retrospective analysis of the efficiency of endoscopic treatment of patients with colloid cysts of the third ventricle. MATERIAL AND METHODS: The analysis covered 17 patients. There were 19 operations in total. The follow-up period ranged from 21 to 130 months. The effectiveness of the method was evaluated by comparing neurological condition and magnetic resonance imaging (MRI) before and after treatment. RESULTS: The mean duration of surgery was 81 minutes. The cyst was removed completely in 8 patients, subtotally in 5, partially in 3, and in 1 case a biopsy was performed. No persistent intra- or postoperative complications or deaths occurred. Immediately after the operation symptoms withdrew completely in 8 patients and partially in 9. In the long term follow-up period, all symptoms receded completely in 11 patients and a further 6 patients showed partial improvement. MRI revealed the absence of the cyst in 8 patients, in 2 patients the tumor was smaller in size and in a further 7 patients some small parts of the walls of the cyst were present. The width of the ventricle system returned to its normal size in 8 patients, decreased in 8 patients and in 1 case remained at its initial size. In 2 patients temporary postoperative complications occurred. The average hospitalization time was 9 days. CONCLUSIONS: Recurrences of colloidal cysts after subtotal and partial removal do not occur very often, and the time of the recurrence may either be very long or it may not happen at all. Although we recommend complete removal of the cyst, this should not be pursued at the cost of incurring operative complications.

Brain biopsy and other stereotactic procedures have evolved over the last decades. Recently, the morbidity and mortality decreased radically along with an increase in the number of successful histopathological diagnoses. Therefore, applications of appropriate treatments in neoplastic brain pathologies are now possible, especially of those located in deep regions. Stereotactic biopsy may also be used as a diagnostic method followed by appropriate management in conditions where a non-neoplastic pathology is suspected. Between December 2000 and February 2004, we performed 116 stereotactic procedures based on the system of stereotactic planning and Brain-Lab treatment, which was equipped with automatic CT/MR image fusion software. In this report, we have focused on 10 cases of non-neoplastic brain pathologies diagnosed on the basis of ultra-small samples obtained from stereotactic biopsy. Among them there were 4 cases of gliosis, 3 cases of brain degenerative disorders, 2 cases of hippocampal fibroses, and 1 case of normal brain tissue. We have presented all these cases in detail by discussing their histology, clinical manifestations, localisation, management and follow-up.

In the Neurosurgery Department, Silesian University School of Medicine, continuous monitoring of selected neurophysiological functions of the central and peripheral nervous system was introduced in 1998 as a routine procedure in cerebellopontine angle surgery and some other operations performed in the petroclival region. Such benefits from this method as increased patient safety, availability of information about dynamic changes in the monitored structures, and the possibility of cranial nerves localization using stimulation in the operating area, are quite obvious. The paper presents results of a detailed statistical analysis of the amount of time required for preparation and for operating in 174 cerebellopontine angle tumor surgeries performed in the years 1986-2002 with (group M) and without (group BM, before the year 1998) intraoperative monitoring. Subgroups distinguished according to the histological type of tumor were evaluated. Out of 95 procedures performed in group M, 57 were operations of acoustic neurinoma cases, 15 meningiomas, 8 cases of epidermal cyst, and 15 other growth processes in the cerebellopontine angle region. Among 79 operations in group BM, there were 57 cases of acoustic neurinoma, 4 cases of meningioma, 8 cases of epidermal cyst, and 10 of other types of neoplastic growth. In group M as compared to group BM the pre-op. preparation time was found to be significantly longer in cases of the VIII-th nerve neurinoma, and of other tumors. No statistically significant differences in the amount of operating time in were found between any of the subgroups. Both radicality of tumor removal and facial nerve status have clearly improved since intraoperative monitoring was introduced.
