    ABSTRACT: Debate continues as to whether decompressive craniectomy (DC) is an effective treatment for severe traumatic brain injury (STBI). DC is mostly used as a second tier treatment option. The aim of this study was determined whether early bilateral DC is effective as a first tier treatment option in patients with STBI. The study compared two groups. Group 1 comprised 36 STBI patients for whom control of intracranial pressure (ICP) was not achieved with conservative treatment methods according to radiological and neurological findings. These patients underwent bilateral or unilateral DC as a second tier treatment. Group 2 comprised 40 STBI patients who underwent early bilateral DC as a first tier treatment. Group 2 patients had a mean better outcome than Group 1 patients especially for patients with a GCS 6-8. Postoperative ICP was lower in Group 2 patients than Group 1 patients. This study indicates that early bilateral DC can be effective for controlling ICP in STBI patients. It is likely the favorable outcome results for Group 2 patients reflects the relatively short time between trauma and surgery. Therefore, these data indicate early bilateral DC can be considered as a first tier treatment in STBI patients.

    ABSTRACT: Traumatic cervical spondyloptosis has almost always been associated with disabling neurological deficit and we could only find one case without a neurological deficit reported in the literature. A 42 year old man suffering from severe neck pain following a high speed motor vehicle accident was admitted to our hospital. Magnetic resonance imaging (MRI) and computerized tomography (CT) of the cervical spine and neurologic examination of the patient were performed. The patient was treated with three-column fixation of the traumatic level. We aimed to report a unique case of traumatic C7-T1 total spondyloptosis without a neurological deficit and discuss possible mechanisms and treatment modalities.

    ABSTRACT: Temporal meningocele is a rarely encountered pathology. It is caused by communication between the subarachnoid space of the middle fossa and lateral extension of the sphenoid sinus. Cerebrospinal fluid (CSF) pressures and the hydrostatic pulsatile forces may lead to the development of pitholes on the middle fossa at the sites of arachnoid villi with herniation of dura/arachnoid or brain tissue into the sinus. We describe an adult patient who presented with spontaneous CSF rhinorrhea due to a temporal meningocele. She was first operated on transsphenoidally, but the CSF rhinorrea did not cessate, therefore she was operated transcranially five days after the first operation. There has been no CSF rhinorrhea for three and a half years. Transcranial temporal encephalocele repairment is more effective than transsphenoidal surgery. Recurrent CSF leaks can occur due to both the increased CSF pressure and the insufficient operation technique.

    ABSTRACT: Spinal epidural hematoma (SEH) is a known complication of spinal surgery, but the incidence of post-surgical SEHs that result in neurologic deficits is extremely rare (0.1%). Patients that require multilevel lumbar procedures and/or have a preoperative coagulopathy are at a significantly higher risk of developing an epidural hematoma. The introduction of higher dose of low molecular weight heparin (LMWH) twice daily 30 mg regimen) increased the reported incidence of neuroaxial hematomas. Surgery performed within 8 hours makes good or partial recovery of neurologic function. Our patient was also started on higher dose of LMWH and developed neurological deficits due to a SEH following lumbar puncture. She underwent operation after six days and she had a mild recovery following the operation. Current administration of high doses of LMWH can cause SEH even after a lumbar puncture, which was performed without multiple attempts. Although surgery performed within 8 hours makes good or partial recovery of neurologic function, laminectomy and epidural hematoma evacuation performed after three days can also have successful results.

    ABSTRACT: El hematoma espinal epidural (HEE) es una complicación conocida en la cirugía espinal, pero la incidencia del HEE que da lugar a déficit neurológico es muy rara (0,1%). Los pacientes que necesitan intervenciones en varios niveles lumbares y/o que tienen una coagulopatía preoperatoria tienen un riesgo significativamente mayor de desarrollar un hematoma epidural. La introducción de dosis altas de heparina de bajo peso molecular (HBPM), (30 mgrs. dos veces al día) aumentan la incidencia de hematomas neuroaxiales. La cirugía llevada a cabo dentro de las 8 horas da lugar a un recuperación buena o parcial de la función neurológica. Nuestro paciente fue tratada con dosis altas de HBPM y desarrolló un déficit neurológico debido a un HEE, después de una punción lumbar. Fue operada al cabo de seis días y se recuperó parcialmente de su déficit después de la intervención. La administración actual de dosis altas de HBPM puede dar lugar a HEE, incluso después de una punción lumbar, que se hizo en pocos intentos. Aunque la cirugía realizada en las primeras 8 horas produce una recuperación buena o parcial, la laminectomía y evacuación del hematoma llevada a cabo después de tres días también puede dar lugar a buenos resultados.

    ABSTRACT: A connective tissue sheath that forms around the peritoneal catheter of silicone ventriculo-peritoneal (V-P) shunt tubing is quite often observed in children with V-P shunts. However, proof of the passage of cerebrospinal fluid (CSF) through these sheaths has been reported in only one published study to date. We present four cases associated with chronic malfunction of the V-P shunt peritoneal catheter. In these cases, CSF passage through the subcutaneous fibrous tract, which had a pericatheter connective tissue sheath, was demonstrated around the V-P shunt peritoneal catheter. In the first case the patient suffered intermittent headache attacks over a long period of time; abdominal migration of the peritoneal catheter was detected. The second patient, who had been asymptomatic in the follow-up period with an outgrown peritoneal catheter, was admitted with acute hydrocephalus symptoms. A peritoneal catheter disconnection was detected in another patient, who had had multiple shunt revisions previously. In the last case, an obstruction of the peritoneal catheter was detected. The existence of the subcutaneous fibrous tract and its function were demonstrated by radio-opaque shuntogram in two cases and radionuclide shuntogram in the other two cases. In all four cases V-P shunt revision was performed. Within this study, the possible passage of CSF through a fibrous tract in cases of migration, outgrowth, disconnection or obstruction of the peritoneal shunt catheter was demonstrated. In conclusion, patients with shunt malfunction with a well-grown pericatheter fibrous sheath who are either asymptomatic or minimally symptomatic and show no evidence of active ventricular dilatation on their cranial CT scan should not be regarded as having arrested hydrocephalus until radio-opaque or radionuclide shuntogram studies have been done.

    ABSTRACT: In conservative management of extradural haematomas (EDH), several mechanisms were described to explain the resorption of the haematoma. One of these was the transfer of the clot into the epicranial space through the skull fracture. In this study, the effects of skull fracture and associated intracranial lesions in the conservative management of EDH were investigated. Skull fracture and associated intracranial lesions were found in 71.11% and 51.1% of the patients, respectively. Resorption rate was calculated using an original formula and it was 0.548 +/- 0.227 in patients with skull fracture and 0.507 +/- 0.170 in patients with both skull fractures and additional intracranial lesions. These rates were found to be significantly higher than in the patients without fracture. In conclusion, in the patients with EDH planned to be managed conservatively, skull fracture and additional intracranial lesions must not be thought as risk factors, on the contrary, resorption of the clot might be earlier than in the others.

    ABSTRACT: Conservative management of epidural haematoma (EDH) depends on a balance between expansion and resorption rate of the clot. 15 patients with EDH whose CT scans demonstrated a small EDH and were asymptomatic or with minor symptoms or with a delayed diagnosis were treated conservatively. The thickness of haematoma ranged between 4.9-40.8 mm. In two patients, the haematoma extended from the posterior fossa to the supratentorial region. In 7 patients, additional intracranial pathology was detected. None of the patients had neurological deterioration on follow up. The second CT was performed on second day at the earliest, in fourth week at the latest. We conclude that the patients with EDH who are neurologically stable during the first 24 hours after trauma, with small EDH and with minor or no symptoms or signs, might be candidates for conservative management. An absolute precondition for conservative management is close supervision of the patient.
