Intraoperative visual inspection confirmed that the ophthalmic artery was left intact. She had no light perception on the operated side right after surgery. Angiography one week after surgery confirmed exclusion of the aneurysm, no filling of the proximal portion of the ophthalmic artery, and a very faint filling of its distal orbital part. She gradually recovered from this deficit and 9 months after surgery she is capable of counting fingers. At this time angiography displayed filling of all the portions of the ophthalmic artery, absence of recruitment of collateral blood supply, and exclusion of the aneurysm as before. Surgical ma...

In our element, the variations of atmospheric pressure are not related to an increase of incidence of the subarachnoid hemorrhage. Instead of this, cases of subarachnoid hemorrhage take place with changes of hardly 1.7 (1-3) hPa in the day, without observing a clear seasonal tendency.

For the first time in the literature a case of Glandular MPNST located at the orbit, which occurred in child with NF1, is described. This extremely uncommon neoplasia must be taken into account, in the study of biphasic malignant lesions, as its diagnosis is of great importance because of the bad prognosis of the affected patients.

It is wise to invest time to deal with patients, including the verbal informed consent, which must be confirmed by the written informed consent form. It is also important to leave a written proof of medical praxis, both related to surgical records and to diagnosis and follow-up of the patient. Procedures with a lower life-threatening risk should not be underestimated, since they comprise the greatest demanded group. The greatest amount of demands is related to economic reimbursement, especially in private practice.

The best results were obtained in patients with isolated craniosynostosis and the worst in cases with syndromic and multi-suture craniosynostosis. The rate and severity of complications were related to the type of surgical procedure and was higher among patients undergoing re-operations. The mean time of hospitalization was also modified by these factors. Finally, we report our considerations for the management of craniosynostosis taking into account each specific technique and the age at surgery, complication rates and the results of the whole series.

Real-time 2-D ultrasonography affords an adequate image quality for performing guided-craniotomy in supratentorial brain tumours, as it allows for a safe and accurate localization of the lesions. Its use is mainly indicated in the removal of tumours located in, or close to, important anatomical and functional brain areas and to depict the presence of tumour rests after surgical removal of cerebral neoplasms.

Kyphoplasty could constitute an alternative and/or complementary treatment of traditional spinal stabilization-fusion procedures in non osteoporotic vertebral fractures. Therefore, it should be offered, when indicated, as a substantial possible part of the treatment, to the patients suffering from vertebral fractures. Additional advantages of combining kyphoplasty and posterior fusion are the possibility of reducing the number of fused levels (shorter instrumentations), and to perform a 360 degree stabilization-remodeling through a single posterior approach.

We diagnosed and treated a total of 42 patients between 1988 and 2006; 36 of them were operated with partial resection in most cases. Brain-stem tumors constitute a rare condition with very bad prognosis. A surgical complete resection of the mass is not possible in most cases, so the principal surgical objetive is reduction and descompression. The best prognosis is seen in patients with low grade tumors with minimal neurologic deficit. Most of these tumors cause death in a short period, usually one year or less.

Syringes are caused by obstructions of CSF pathways of different causes. If we can not find a cause responsible for the blockage, we called it "idiopathic" syringomyelia. Drainage procedures have been widely used but results, especially long-term results, are not favourable and complication rate is high. Some authors prefer to restore CSF circulation instead to drain the syrinx. Results of this treatment modality are better in literature than drainage procedures. Adequate radiological studies help to identify problem location and to plan the approach. A case of "idiopathic" syri...

The most accepted treatment of NPH is the placement of a cerebrospinal fluid shunt. Owing to the characteristics of the patients and the invasive nature of the surgical treatment, it is fundamental to detect those patients who could obtain a greater benefit from the treatment. Neuropsychological assessment of these patients could significantly contribute to a better diagnosis of NPH, determining a cognitive deterioration profile for these patients, allowing the assessment of treatment efficacy and helping to detect other additional causes of dementia.

Coronal incision allows any bone orbitotomy, with security, guarantee and good aesthetic and functional results. Lateral and supero-lateral orbitotomies provide an ideal extradural approach to the retrobulbar compartment.

The most accepted treatment of NPH is the placement of a cerebrospinal fluid shunt. Owing to the characteristics of the patients and the invasive nature of the surgical treatment, it is fundamental to detect those patients who could obtain a greater benefit from the treatment. Neuropsychological assessment of these patients could significantly contribute to a better diagnosis of NPH, determining a cognitive deterioration profile for these patients, allowing the assessment of treatment efficacy and helping to detect other additional causes of dementia.

Coronal incision allows any bone orbitotomy, with security, guarantee and good aesthetic and functional results. Lateral and supero-lateral orbitotomies provide an ideal extradural approach to the retrobulbar compartment.

A yellowish mass was observed in the frontal lobe. The content of the cyst consisted of old hematoma, xanthochromic fluid and necrotic tissue, was evacuated and the cyst wall was totally resected. No abnormal pigmentation was noted in the cyst wall and surrounding brain tissue. The imaging features of metastatic melanomas are distinctive due to the presence of melanin and the propensity for hemorrhage.

Ibn Sina (known as Avicenna in the West), who was among the leading figures during medieval ages and influenced the upcoming periods in the Eastern and Western hemispheres for long time, focused also on these crucial problems. In his principal medical work, the Canon of Medicine, Avicenna underlined the significance of wry mouth-related disorders and wrote a precise chapter over this topic with the heading "Laqve."

The aim of this study was to review the existing evidence supporting surgical evacuation of the haematoma in this pathology. Without any clinical trial on this field, data derived from clinical series suggest that the level of consciousness, the size of the haematoma, the presence of hydrocephalus and the compression of the posterior fossa CSF containing spaces are the main criteria to decide management.

The inter-relationship between the brain and the computer (brain-machine interface) has already occurred and has been applied in the field of neuroprosthetics and deep brain stimulation. For neurosurgery in general and for Spain in particular, this represents a new opportunity to embark on a high technology path that would involve years of research but, applying these new, non-invasive surgical techniques would help resolve the neurological problems of many of our patients.

The choice treatment is laminectomy and total excision. Probably, this is one of the easiest tumours to remove of the spinal canal and a source of satisfaction because a complete recovery can usually be achieved.

However, and despite a high incidence, medical treatment is almost limited to life support and to control intracranial hypertension and indications of surgical treatment are poorly defined. The aim of this paper was to review the evidence supporting surgical evacuation of SICH. Ten clinical trials and five meta-analyses studying the results of surgical treatment on this pathology were found on English literature. These studies considered all together, failed to show a significant benefit of surgical evacuation in patients with SICH considered as a whole. However, a subgroup of these ...

In spite of previous reports that show a high incidence of bleeding lesions, cavernomas may be found incidentally during the neuroimaging surveillance studies that are performed to children with brain tumors previously treated with radiotherapy. In these cases, a conservative attitude seems to be advisable, reserving surgery only for those lesions that grow or bleed.

CT scan and MR imaging revealed a giant osteolytic extradural lesion of the posterior fossa (5.2 cm x 3.8 cm) with a small area of peripheral enhancement after contrast injection. Retrosigmoid suboccipital craniectomy allowed a satisfactory removal of the tumor, followed by an acrylic cranioplasty. The outcome was good. Neuropathological examination confirmed an epidermoid cyst. We review the literature and discuss our case.

We obtained data from at least one neurosurgeon from the 74 neurosurgical centers in Spain (response rate= 100%). Only 6 neurosurgeons performed psychosurgical interventions. In total, 121 psychosurgeries were performed between 1999 and 2003, 75.7% of them in private centers. The most frequent indication is obsessive-compulsive disorder and the most frequent technique is anterior capsulotomy, although techniques and indications differ among the practising neurosurgeons.

The coexistence of these two formats raises some issues regarding their justification and their future evolution, e.g. why does a subscription- based journal offer free online access?

Therefore, each lesion should be idetified by the location of the neck (extradural: C4 and C5 segments; intradural: C6 segment), fundus projection and location (intradural / extradural). The microsurgical clipping of the paraclinoid aneurysms is made easier after intradural anterior clinoidectomy, but this manoeuvre is mandatory for trans-segmentary C5-C6 lesions.

Cervical anterior approach, is a simple technique, and safe surgically procedure with under number of complications. 2.

Have been many the procedures used for the cervical spine fixation, with more than 40 years of experience, and still it is to define as he is the best one. It would be necessary more studies of prospective multicentric character to be able to compare clinical, radiological results, and the presence of complications.

Persistent metopic suture may be misdiagnosed as a vertical traumatic skull fracture extending in the mid-line in head trauma patients. Therefore the surgeon should be aware of this anatomical condition in the primary and secondary surveillance of the traumatized patient and during surgical intervention including especially frontal craniotomy. Reconstructed tomography scan demonstrating sutural closuring status may provide additional informative value in the diagnostic sequence superior to plain X-ray in the emergency setting.

The literature regarding CLF is reviewed. CASE REPORT: A 65 year-old female suffered mild cervical trauma as a consequence of a car accident. A year later she referred progressive cervical and upper dorsal pain without any sensory or motor defect. Spinal magnetic resonance images showed a well-delineated posterior epidural mass, from C2 to T2, which compressed the spinal cord, without signal of myelopathy. She underwent bilateral laminectomy of the affected levels but no clear improvement occurred. The pathological study of the resected pieces showed a remarkable calcification of the ligamentum flavum.

The results suggest that neuro-stimulation spinal cord electrical stimulation can increase cerebral blood flow in cancer patients. The implication is that this technique could be useful in modifying locoregional ischemia in brain tumors thus improving the outcomes of after radio-chemotherapy. Further research is in progress to confirm the advantages of the technique.

The patient was fully conscious at clinical onset, and thus we treated her conservatively with an epidural autologous blood patch and close neurological observation. Given the clinical improvement the possibility of surgery was discauded in agreement with the neurosurgical team. Most cases of subdural hematoma appearing after spinal anesthesia are treated with surgery. In the present case the subdural hemorrhage was detected at our hospital 20 days after the anesthetic procedure, and given the excellent state of consciousness, we choosed a conservative management.

CT scanning showed a suprasellar hemorrhage. She underwent surgery with the presumptive diagnosis of pituitary tumor. At surgery, we find a brown-grayish lesion involving left optic nerve and chiasm. Cavernous angioma was diagnosed by histopathology. Cavernous angiomas constitute nearly 15% of all central nervous system vascular malformations. Location at the optic pathway is very rare, but must to be ruled out in the diagnosis of a patient with chiasmatic and/or optic apoplexy.

They needed surgery to remove the sacs, for a different reason. The older one had a fistulous abcess but the LCR did not come out, and it did not improved by the application of topic and antibiotic treatment. The other patient showed a progressive growth of the malformation during the last year, skin hardening and pain. The histological study of the dried sacs proved the existence of a carcinomatous degeneration. In the patients we have treated, it seems that a chronic irritation of the LCR and the appearance of multipotent cells in the meningocele may favour the malignancy of the tissues surrounding the sac.

Nowadays, with high resolution imaging, we can see both anatomic and functional aspects of the fractures, as well as understand the mechanisms of injury. This can also allow us to study the evolution of the soft tissue lesions and fractures. The classification of traumatic injuries in C0-C1-C2 is basic in order to understand the mechanism of injury and natural history of these lesions. This also allow us to choose the correct or most adequate form of treatment.

The pitfalls encountered in the assessment on the cause of the bilateral frontal and interhemispheric subdural hematomas in this child are also briefly discussed. We have called this condition "benign" shaken baby syndrome and emphasize that not always acute subdural hematomas are of non-accidental nature.
