Öğe Bilateral carpal and tarsal tunnel syndrome in the same patient: A case report(Journal Neurological Sciences, 2008) Serarslan, Yurdal; Kalacı, Aydıner; Akdemir, Goekhan; Yanat, Ahmet NedimWe report, an unique case with co-existing bilateral severe tarsal tunnel syndrome (TTS) and bilateral severe carpal tunnel syndrome (CTS), which were diagnosed by clinical examination and electrophysiological studies. Compression neuropathy, especially when bilateral or multiple may be secondary to a systemic disease. To date, bilateral carpal and tarsal tunnel syndromes in the same patient have been reported only a few cases in the literature.Öğe The co-occurrence of Chiari type 1 malformation with syringomyelia and total situs inversus(Int Scientific Literature, Inc, 2007) Serarslan, Yurdal; Melek, Ismet M.; Duman, Taskin; Eraslan, Turali; Akdemir, Goekhan; Yalcin, FatihBackground: Total situs inversus (TSI) is a rare congenital anomaly that often occurs concomitantly with other disorders. TSI is the complete left-to-right inversion of the thoracic and abdominal organs. It develops due to an abnormal rotation of the cardiac tube during embryogenesis, the mechanism of which is of unknown mechanism. Syringomyelia (SM) is an uncommon disease of the spinal cord and is known as the occurrence of a cystic space in the middle of the spinal cord. SM occurs due to spinal cord injury, a primary tumor of the spinal cord, or an extramedullary lesion at the foramen magnum such as a Chiari type I malformation (CMI). In the literature there has been reported association of CMI and SM (CMI/SM) with known genetic syndromes. Case Report: We report a 33-year-old female with CMI/SM coexisting with TSI. Our patient presented with pain in the neck, arm, and upper back. She had no trsuma history. There was dysesthesia in the cervical-2 dermatomes. Radiological tools revealed that CMI/SM with TSI accompanied by no other abnormality. Conclusions: It can be suggested that the existence of this case indicates that genetic factors rnay influence the pathogenesis of some CMI/SM cases.Öğe Macrocephaly and bitemporal arachnoid cysts not associated with glutaric aciduria type I in a child(Turkish Neurosurgical Soc, 2008) Serarslan, Yurdal; Melek, Ismet Murat; Sangun, Ozlem; Akcora, Buelent; Akdemir, GoekhanA 45-month-old child who had bitemporal arachnoid cysts and macrocephaly unrelated to glutaric aciduria type 1 (GA 1) was reported. The patient was admitted to the emergency unit after head trauma at 11 months of age. CT and MRI showed bitemporal arachnoid cysts (BACs). Acylcarnitine profile was normal in serum using tandem mass spectrometry. Urine and blood screening tests were within normal range for metabolic disorders. There were no unusual organic acids in urine and blood samples. No additional clinical findings of metabolic disorders such as GA I developed during follow-up. The majority of children affected with GA 1 have macrocephaly and BACs on CT or MRI. These signs should alert neurosurgeons to the possibility of GA 1. Neurosurgeons evaluating patients with head trauma or suspected non-accidental head injury should include GA 1 in the differential diagnosis of BACs associated with macrocephaly, and an evaluation should be performed.Öğe Thoracic and lumbar intraforaminal ligaments Laboratory investigation(Amer Assoc Neurological Surgeons, 2010) Akdemir, GoekhanObject. The author conducted a study to investigate the anatomy of the intraforaminal ligaments of the thoracic and lumbar nerve roots and describe their anatomical relationships and functional properties. This anatomical study performed on the intervertebral foramina, intraforaminal ligaments, transforaminal ligaments, and nerve roots of the thoracic and lumbar spine was performed in human cadavers. Methods. The foraminal anatomy was studied in 11 whole cadavers (5 females, 6 males) previously prepared with formaldehyde, whose ages at the time of death ranged from 16 to 71 years. The thoracic and lumbar spinal columns were separated from the cervical and sacral segments en bloc using an electric band saw. The paraspinal muscles and their attachments were removed by sharp and meticulous dissection, and the thoracic and lumbar intervertebral foramina were examined under a surgical microscope. The intervertebral foramina! ligaments and nerve roots were exposed. The foraminal contents were identified and studied in detail. The intraforaminal ligaments were stained using H & E to determine ligamentous fiber. Results. Intraforaminal ligaments connect the periosteum and transforaminal ligaments to the nerve root sleeves and vessels within the fatty areolar tissue. Histologically, the ligamentous attachment of the nerve roots within the foramina consists of adipose and connective tissue. Conclusions. The nerve roots are surrounded by intraforaminal ligaments, which may act in conjunction with the dura and periosteum to protect the nerve roots mechanically. (DOI: 10.3171/2010.3.SPINE09799)
