Factors Influencing Intraoperative Rupture of Intracranial Aneurysms.

Aim: The study deals with intraoperative rupture of intracranial aneurysms (IOR) during microsurgery, analyzing factors that may be connected with IOR.

Material And Methods: During the three-year period (2006-2008), 934 patients were operated for aneurysms at the Institute of Neurosurgery, CCS, Belgrade. In total, 536 patients were observed.

Cervical spinal epidural abscess after oesophagoscopy.

Introduction: Spinal epidural abscess is an uncommon entity, especially in the cervical region.

Case Report: We report a patient with epidural abscess, vertebral osteomyelitis and discitis in the cervical spine that was caused by iatrogenic perforation of the pharynx during diagnostic oesophagoscopy, which has not been recorded previously in the literature.

Conclusion: Cervical spinal epidural abscess may be caused by iatrogenic perforation of pharyngeal wall during diagnostic oesophagoscopy.

A retrospective analysis of anesthesiologic complications in pediatric neurosurgery.

Background And Objective: Different clinical and surgical factors can influence the occurrence of anesthesiologic complications in pediatric neurosurgery. Preoperative knowledge of these factors is of great importance in the application of safe anesthetics and a favorable surgical outcome. The objective was to establish the importance of clinical and surgical risk factors on the frequency of anesthesia complications in pediatric neurosurgery.

[Natural history of supratentorial low-grade astrocytoma: case report].

Low-grade astrocytomas comprise a group of primary brain neoplasms with relatively low anaplastic potential, although through time they tend to behave more aggressively. They have a very heterogeneous natural course and clinical behavior. This report presents a natural history of a patient with low grade astrocytoma.

[Clinical characteristics and results of surgical treatment of petroclival meningioma].

Introduction: The size of meningioma and its relation with neurovascular structures in petroclival region stipulate the degree of surgical radicalism and determine an operation risk. In spite of progress of surgical technology, the rate of surgical morbidity in view of cranial nerves deficit is 30%-50%.

Objective: The objective of our study was to present the results of treatment of patients with petroclival meningiomas and to point to correlation of preoperative radiological findings and intraoperative results as well as neurological status of patients before and after surgical treatment.

[Delayed epidural hematoma after mild head injury].

Background: Traumatic delayed epidural hematoma (DEH) can be defined as insignificant or not seen on the initial CT scan performed after a trauma but seen on the subsequent CT scan as a "massive" epidural bleeding.

Case Report: We presented two cases of traumatic DEH after mild head injury. Both patients were conscious and without neurological deficit on the admission.

[The role of surgical decompression of cauda equina in lumbar disc herniation and recovery of bladder function].

Introduction: Cauda equina syvndrome from lumbar disc herniation accounts for up to 2-3% of all disc herniations. The aim of this study was to investigate whether recovery of bladder function after surgery depends on preoperative duration of desease.

Patients And Methods: This retrospective study included 47 patients who underwent surgery for cauda equina syndrome due to a herniated disc in the period between 1997 and 2002.

[Epidural hematomas of the posterior fossa].

Background: Posterior fossa epidural hematomas represent 7-14% of all traumatic intracranial epidural hematomas. They are most frequently encountered posttraumatic mass lesions in the posterior fossa. The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma.
