    Impact of radial extracorporeal shock wave therapy in post-laminectomy epidural fibrosis in a rat model
    (2021) Haberal, Bahtiyar; Simsek, Ekin Kaya; Akpinar, Koray; Simsek, Duygu Turkbey; Sahinturk, Fikret; https://orcid.org/0000-0002-1668-6997; https://orcid.org/0000-0003-3438-1633; https://orcid.org/0000-0002-0471-3177; 33463432; W-9080-2019; AAV-8821-2021; AAI-7972-2021
    Objectives: This study aims to investigate the effect of radial extracorporeal shock wave therapy (rESWT) treatment in the prevention of epidural fibrosis after laminectomy in rats. Materials and methods: Eighteen 16-month-old male Sprague-Dawley rats weighing 300 g were used in this experimental study between November 2019 and February 2020. The rats were randomly divided into two groups as the control group (L3-L4 total laminectomy without any treatment) and the study group (L3-L4 total laminectomy plus rESWT). The rats were sacrificed at the postoperative sixth week and the lumbar spine was excised en bloc, fixed, and decalcified. Sections were stained with hematoxylin-eosin to evaluate epidural fibrosis, acute inflammation, chronic inflammation, and vascular proliferation. Results: The median value and standard deviations were obtained based on histological examinations. Accordingly, epidural fibrosis decreased significantly in the study group compared to the control group. There was no statistically significant difference between the groups in terms of acute and chronic inflammation response and vascular proliferation. Conclusion: The rESWT application immediately after surgery is effective in preventing epidural fibrosis after laminectomy in rats.

    Stereotaxic Biopsy Experience
    (2020) Dere, Umit Akin; Sahinturk, Fikret; Sonmez, Erkin; Gulsen, Salih; Yilmaz, Cem; Altinors, Mehmet Nur
    Aim: To review the outcomes and complications of stereotactic biopsy procedures performed at Neurosurgery Department of Baskent University and make an overall evaluation of the stereotactic biopsy system. Materials and Methods: Medical files of 151 patients who underwent stereotaxic biopsy procedure between 1996 and 2018 were retrospectively analyzed.The , age and gender of the patients, intracranial localization of the lesion and histopathologic diagnosis were evaluated. Result: The series included 84(55.6%) males and 67 (44.4%) females. The average age was 47.7 and the age spectrum was between 26-84 years of age. In 102 cases (67.55%) lesions had lobar localization and in 42 lesions (27.82%) the pathology was deep seated lesion. In 7(4.6 %) there were multiple lesions. A histopathologic diagnosis was obtained in 125 (82.79 %) cases. In 16 (%10.59 %) it was reported as brain tissue and in 10 cases (6.62 %) the histopathologic diagnosis was gliosis. A second stereotactic bipsy procedure was performed in 8 cases while in one patient a third biopsy became necessary. Thirteen patients underwent craniotomy and tumor excision as further therapy. Conclusion: Stereotactic biopsy sampling of intracranial space occupying lesions is a safe, simple and highly diagnostic method. In some cases it may contribute to further therapy. The problems encountered are inconclusive diagnosis, inadequate representation of the specimen due to its limited nature and some technical difficulties.
