CORRELATION OF PERITUMORAL BRAIN EDEMA WITH MORPHOLOGICAL CHARACTERISTICS AND KI67 PROLIFERATIVE INDEX IN RESECTED INTRACRANIAL MENINGIOMAS.

The aim of the study was to analyze correlation between morphological characteristics of intracranial meningiomas and Ki67 labeling index (Ki67 LI), and their influence on peritumoral brain edema (PTBE). There were 41 consecutive patients with intracranial meningiomas surgically treated at the Department of Neurosurgery, Zenica Cantonal Hospital, Zenica, Bosnia and Herzegovina, during the period from January 2010 to December 2015. We reviewed clinical data including patient age, gender, magnetic resonance imaging (MRI) characteristics of the tumor and peritumoral edema, tumor margins, intraoperative characteristics, histopathologic grade and Ki67 LI.

Morphometric study of the anatomic relationship between large retroperitoneal blood vessels and intervertebral discs of the distal segment of the lumbar spine: a clinical significance.

Aim To analyse potential clinical implications of the distance between large retroperitoneal vessels and lower segment of the lumbar spine in the supine and prone position. Methods Prospective, non-randomised study included 40 patients of different age and gender. For all patients magnetic resonance imaging of the lumbar spine was performed in supine and prone position.

Spontaneous brain and arachnoid herniation into the dural venous sinuses: a rare anatomic variation or clinical entity?

Aim To investigate the presence, type and distribution of spontaneous brain and arachnoid herniation into the dural venous sinuses as well as a clinical significance of these herniations. Methods This retrospective - prospective, non-randomised anatomical and clinical study included 990 patients who were referred to Magnetic Resonance Imaging at the Department of Radiology of the Cantonal Hospital in Zenica in the period from January to December 2016. The T1 and T2 sequences in axial, sagittal, and coronary section were used for brain or arachnoid herniation analysis.

Impact of timing on surgical outcome in patients with cauda equina syndrome caused by lumbar disc herniation.

Aim To analyze the relationship between timing of surgery and outcome in patients with cauda equina syndrome caused by lumbar disc herniation. Methods A retrospective, non-randomized clinical study included 25 consecutive patients with cauda equina syndrome (CES) caused by lumbar disc herniation. All patients were operated within 24 hours after hospitalization at the Department of Neurosurgery, Cantonal Hospital Zenica, Bosnia and Herzegovina, between January 2000 and December 2010.
