Use of diffusion tensor imaging to assess the vasogenic edema in traumatic pericontusional tissue.
The objective of this prospective, observational study was to assess the characteristics of the vasogenic edema in the traumatic pericontusional tissue and compare it to the vasogenic edema found in brain tumors. We also included a control group. METHODS: Using DTI, the Apparent diffusion coefficient (ADC) and Fractional anisotropy (FA) were measured in the area of vasogenic edema in both TBI and tumor patients. The measurements in the control group were done in the gray and white matter. We included 15 TBI patients, 18 tumor patients and 15 controls. RESULTS: ADC and FA showed no differences between TBI and tumo...

Transcervical approach with endoscopic assistance for surgical treatment of patient with irreducible atlantoaxial dislocation: a case report.
Abstract We demonstrate the case of a surgery in a patient with irreducible atlantoaxial dislocation (IrAAD) after C2 fracture. The challenges of this case were the flexed head in a forced position, impossibility of neck extension, and revision operation after posterior occipito-cervical fixation. The patient underwent the following surgeries: 1. A ventral release of C1-C2 using transcervical endoscopy; 2. Removal of occipito-cervical system and fibrous block resection in the posterior surfaces of the C1-C2; 3. Reducing of AAD and odontoid screw fixation; 4. Posterior C1-C2-C3 screw fixation. Ankylosing of C1-C2 a...

Lumbo-peritoneal shunt as treatment modality for visual symptoms in idiopathic intracranial hypertension: A single institution experience.
CONCLUSION: LPS is an equally effective and more technically familiar modality for treatment of IIH for neurosurgeons and should be offered to asymptomatic patients with objective visual signs. Shunt extrusion/migration may not always warrant revision due to "mini-shunt" that drains Cerebro-Spinal Fluid (CSF) through shunt tract even after extrusion.

Abdominal pseudocysts, an unusual complication of ventriculoperitoneal shunt systems: Literature systematic review.
as P, Pascual-Argente D Abstract Since the first report in 1954, abdominal pseudocysts have been recognized as a particularly uncommon complication of ventriculoperitoneal shunts of CSF, so their etiology, diagnosis, and therapeutic management remain very controversial. Our objective is to offer a critical and updated systematic review of those controversial points, using a thorough search and review of the most relevant literature available. The clinical presentation of pseudocysts is normally through non-specific abdominal symptoms. The most validated etiology consists on the existence of a concomitant infection...

Importance of cerebral angiography and intraoperative neuromonitoring in carotid endarterectomy.
We present a case of symptomatic left carotid artery 80% stenosis in which cerebral angiography showed absence of the right A1 segment and bilateral anterior cerebral artery territories that filled only from a left injection. Just 90seconds after carotid artery clamping at the neck, brain oximetry and somatosensory evoked potentials significantly dropped, that recovered after immediate clamp removal. Endarterectomy was dismissed and a carotid stent was successfully placed. This case highlights the importance of knowing the dynamics of cerebral blood circulation distal to the stenosis. If endarterectomy had been attempted, ...

We present a case of a foot drop, caused by a disc herniation after percutaneous treatment with Discogel®.

Most are located at the temporal lobe, and as symptomatology more frequent epileptic seizures of difficult pharmacological control. In general, they have a good prognosis after surgical resection. The anaplasic variant, considered to be gradeIII of the WHO, presents greater clinical and radiological aggressiveness.

-García EM Abstract The main goal of treatment in spinal metastatic patients is local control of the disease, pain relief and the maintenance of ambulation. Traditionally, wide surgical resection of the tumour followed by adjuvant radiation and/or chemotherapy has been recommended. Currently, single-fraction or hypofractionated stereotactic body radiation therapy (SBRT) yields a one-year local control rate of over 95% with minimum morbidity, even for tumours previously considered radioresistant. In addition, by posterolateral and circumferential decompression and stabilisation of the spinal cord, it is feas...

Mobile application to analyse surgical experience.
CONCLUSIONS: The Electronic Neurosurgical Register is an innovative technological tool that supports the fields of care, teaching and research. It records the exact number of patients who have undergone surgery at a particular time, providing valuable information for the proper management of resources. The data obtained can be used to identify areas of opportunity in the training of residents, facilitating the development of continuous improvement strategies in the training of competent neurosurgeons.

Trigeminal root massage in microsurgical treatment of trigeminal neuralgia patients without arterial compression: When, how and why.
CONCLUSIONS: The described maneuver provides an easy and simple alternative way in cases where during a microsurgical exploration of trigeminal root, where we don't find a clear arterial compression, with similar results than other possibilities such as partial sensory rhizotomy or more complicated and time consuming surgery as "nerve combing". Nevertheless, a 40% of pain recurrence after an average follow-up of 5 years means that is a good alternative, but not a definitive technique at the moment for permanent cure of trigeminal neuralgia without arterial compression.

Atlantoaxial subluxation secondary to retropharyngeal abcess in adults (Grisel's syndrome). Review of literature about a clinical case.
We present the case of a 68-year-old patient with a history of chronic myeloid leukemia, who presented with infectious polyarthritis, cervicalgia, torticollis and cervical impotence. Cervical radiography, CT, and MRI showed a C1-C2 subluxation adjacent to a pharyngeal abscess, so GS was diagnosed. After antibiotic therapy, the patient had to undergo surgery due to the failure of the closed reduction. Due to its low incidence, there are no clinical guidelines for the management of these patients; The interdisciplinary collaboration is fundamental to establish the opportune diagnosis that allows to establish the conservative...

Vancomycin powder for the prevention of surgical site infection in posterior elective spinal surgery.
CONCLUSION: In posterior elective spinal surgery, prophylaxis with vancomycin powder did not result in a significantly reduced incidence of superficial and deep SSI. There was a trend towards a higher incidence of deep SSI caused by gram negative microorganisms among those treated with vancomycin.

Spinal cord compression secondary to traumatic intradural arachnoid cyst.
We present the case of a male patient with traumatic spinal arachnoid cyst, together with a review of the cases published to date. Finally, we explain the different surgical options for this pathology relating them to the physiopathological theories that try to explain the origin of these lesions.
