    Neurophysiological monitoring in tethered cord syndrome surgery: Two case reports
    (Anatolian Journal of Clinical Investigation, 2014) Güven, Mustafa; Aras, Adem Bozkurt; Şen, Halil Murat; Karavelioğlu, Ergün; Reşorlu, Mustafa; Coşar, Murat
    Tethered cord syndrome (TCS) is a neural tube defect that results from an attachment of the conus medullaris that limits movement of the spinal cord within the spinal canal. Temporary and permanent neurological complications may be observed after microsurgical release of the spinal cord. Currently, intraoperative neuromonitorization is used to decrease morbidity during TCS microsurgery.Pre-and postoperative results for 2 patients with tethered cord syndrome followed by intraoperative neuromonitorization are reported here. © 2014, Anatol J Clin Investig.

    Ruptured Saccular Aneurysms of the Distal Anterior Cerebral Artery : Two Case Reports And A Review of the Literature
    (Çanakkale Onsekiz Mart Üniversitesi, 2014) Güven, Mustafa; Aras, Adem Bozkurt; Akman, Tarık; Karavelioğlu, Ergün; Özbey, Şafak; Coşar, Murat
    Distal anterior cerebral artery aneurysms are uncommon and constitute only 1.5-9% of all intracranial aneurysms. They are frequently observed at pericallosal and callosomarginal artery bifurcations. The surgical treatment of distal anterior cerebral artery aneurysms is difficult due to the narrow surgical field of vision and because these aneurysms are accompanied by interhemispheric adhesions and other aneurysms. Two patients with saccular pericallosal and callosomarginal junction aneurysm were surgically treated in our clinic between April 2012 and October 2013. The clinical and radiological findings in both cases were analyzed. A unilateral interhemispheric approach was employed during surgery. Case reports and series reported in the English medical literature were reviewed. The incidence of distal anterior cerebral artery aneurysm at our hospital was 8% of all aneurysms that were subject to surgery (25 cases). Both patients were women. An interhemispheric approach was used in both cases. One patient was discharged with a full recovery and the other patient expired. We propose that the surgical difficulties encountered in distal anterior cerebral artery aneurysm and related complications will be minimized with use of the latest advances in microsurgical techniques and adequate knowledge of the surgical anatomy.
