    Intracranial Bilateral Subdural Hematoma as a Complication of Lumbar Nucleoplasty
    (Lippincott Williams and Wilkins, 2015) Ceylan D.; Köktekir E.; Tatarli N.; Yaldiz C.; Yücel M.
    Nucleoplasty is a percutaneous intradiscal procedure that uses radiofrequencies to reduce intradiscal pressure and the symptoms associated with the contained lumbar disk herniation. Although patients' outcomes and complications with this technique have not been well documented, there are several reported basic complications such as numbness and tingling, but there are also some vital complications such as discitis, bleeding, even anaphylaxis and death. Here we report a case of bilateral intracranial subdural hematoma as a complication of nucleoplasty for the first time in the literature. This complication should be included in the list of potential complications of nucleoplasty and taken into account in the case of patients who present with headache after nucleoplasty. © 2014 Wolters Kluwer Health, Inc.

    Laboratory training in bifrontal and frontolateral approaches using cadaveric silicone-injected cow craniums [Silikon İnjekte edilmiş İnek kranium kadavrası kullanarak bifrontal ve frontolateral yaklaşımlar İçin laboratuar eğitimi]
    (Ege University Press, 2015) Tatarli N.; Turan Süslü H.; Ceylan D.; Şeker A.; Karabağli H.; Köktekir E.; Özdoğan S.
    Background: A microneurosurgical laboratory training model was designed for trainees in neurosurgery to help them to learn how to handle surgical microscopes and microneurosurgical instruments. A silicone-injected fresh cadaveric cow cranium is a suitable alternative to using a cadaveric human brain for gaining familiarity with the frontal cranial nerves and vascular structures for bifrontal and frontolateral approaches. Methods: A silicone-injected cadaveric cow cranium was prepared by irrigating the major vessels, followed by the injection of silicone colored either red or blue. Results: A three-step approach was designed to simulate microneurosurgical dissection along the frontal lobe and for the dissection of cranial nerves and vascular structures. This laboratory training model is useful for trainees to gain experience in the use of an operating microscope and become more familiar with the anterior neural and vascular structures in bifrontal and frontolateral approaches. Conclusion: The aim of this study was to develop an innovative model to create a life-like microneurosurgical training system. This model simulates bifrontal and frontolateral approaches performed on the human brain. © 2015, Ege University Press. All rights reserved.

    Vascular silicone injection of fresh cadaveric cow cranium: Alternative training model for the human brain [Taze İnek kranium kadavrasının vasküler silikon İnjeksiyonu: eğitim modeli olarak İnsan beynine bir alternatif]
    (Ege University Press, 2015) Tatarli N.; Süslü H.T.; Ceylan D.; Şeker A.; Karabağli H.; Köktekir E.; Özdoğan S.
    Background: Anatomical and physiological variations of the human brain's vascular system can be observed via silicone injection of the arterial and venous systems. As a novel method, the injection of a fresh cadaveric cow cranium with silicone is an alternative to using the human brain for microanatomical studies. Objective: To report on an improved method for the colored silicone injection of a fresh cadaveric cow cranium using a silicone injection technique. Methods: Five fresh cow crania were injected as an alternative to human brains for microanatomical dissection, in which the preparation consisted of the irrigation of the major vessels and the injection of colored silicone. Cannulation of the internal carotid arteries and the internal jugular veins with catheters was performed, and the vasculature was irrigated with water (major arteries and veins). The fixation of the specimen with either formaldehyde or alcohol, and the colored injection of the arteries and veins with red and blue silicone, respectively, was then performed. Results: The silicone injections resulted in the deeper penetration of the colored solutions into the small cerebral vessels and mesenchymal structures of the fresh cadaveric cow crania. Of the five injected specimens, four exhibited successful injections, while one had suboptimal results. Conclusion: Silicone injection of the cadaveric cow brain, based on the anatomical and physiological assessment of the vasculature of the specimen for microanatomical studies, is suggested as an alternative to using human brain specimens. © 2015, Ege University Press.
