Aim: In glioblastoma multiforme, the balance between the procoagulant system, anticoagulant system and fibrinolytic system is impaired in favour of hypercoagulability. The aim of this study was to compare glioblastoma multiforme with astrocytoma grade II by subjectively evaluating the levels of prothrombin and biotinylation thrombin, and G protein serum protease activatin receptors, as tissue factors causing hypercoagulation and affecting coagulation.
Material And Methods: Specimens from 35 cases with glioblastoma multiforme and 23 cases with astrocytoma grade II were evaluated immunohistochemically.
Aim: To review our experience gained from the use of intraoperative ultrasonography (IOUSG) in intradural spinal tumor surgery.
Material And Methods: IOUSG was used during surgery of 69 intradural spinal tumors, operated on between 2012 and 2016. A 5-8 MHz probe of IOUSG was used, before and after durotomy to perform the exact durotomy and myelotomy, and after tumor resection, to detect a residual tumor.
Aim: To analyze the results of stereotactic radiosurgery (SRS) or surgical treatment of 18 cases with cavernous malformation and report 2 cases with unusual localization and size.
Material And Methods: We present 11 and 8 patients who underwent surgery and SRS between 2010 and 2018 respectively. The operated group comprised six men and five women (mean age, 33.
Chronic subdural hematoma is a frequent type of hemorrhage, which terminates with mortality if not diagnosed and treated early. The aim of this clinical study is to evaluate the patients with unilateral and bilateral recurrent chronic subdural hematoma. The study group consisted of 13 cases with unilateral and bilateral recurrent chronic subdural hematomas who underwent aggressive wide craniotomy, duraectomy, inner and outer membranectomy, dural border coagulation, incision through cortical vein trace and hang up of dural edge, between 2009 - 2016.

- The yearly incidence of subdural hematoma is about 13.1 cases per 100,000 people.
- Subdural hematomas caused by metastases from skull and dura mater are uncommon.
- This study discusses a case of a 71-year-old man with prostate adenocarcinoma who developed a chronic subdural hematoma linked to metastasis in the skull and dura mater.
Aim: To examine morphological, radiological and biochemical effects of arginine vasopressin (AV) and V1 receptor antagonist on cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) in rabbits.
Material And Methods: Forty male New Zealand white rabbits were randomly divided into four groups comprising 10 rabbits each. The groups were; 1) Control group, 2) SAH group, 3) SAH+AV group, 4) SAH+V1 antagonist group.
Article Synopsis
- Balloon kyphoplasty (BKP) has been explored as a treatment for both AO type A1 and incomplete AO type A3.1 osteoporotic fractures, although the latter carries a higher risk of cement leakage.
- A study analyzed 138 patients who underwent BKP, examining postoperative CT scans to assess the frequency and patterns of cement leakages associated with different fracture types.
- Results indicated a 30.6% overall leakage rate, with similar rates in AO type A3.1 and various A1 fractures, but higher leakage rates in A3.1 compared to A1.1 fractures and concerning levels of intraspinal leakages, which pose a significant risk.
Object: Fresh autogenous bone graft is the most preferred osteoplastic material, whether the purpose is cosmetic, psychological, or for the protection of the brain. These grafts are not rejected and do not react immunologically. The aim of this study was to evaluate the efficacy of autogenous fat rolled with bone dust derived from the bur hole in closing small cranial defects.
