Abstract
OBJECTIVE Transsphenoidal surgery is the procedure of choice in Cushing disease (CD), with immediate post-operative remission rates ranging between 59 and 94% and recurrence rates between 3 and 46%, both depending upon the definition criteria and the duration of the follow-up. Our aim was to assess the rate of remission, recurrence and persistence of the disease after the first treatment and to identify predictors of remission in the CD population of our center. METHODS Retrospective cohort study of the patients diagnosed of CD and with follow-up in our center between 1974 and 2011. We analyzed 41 patients (35 women and 6 men) with a mean age at diagnosis of 34 ± 13 years. The mean follow-up was 14 ± 10 years (range 1-37 years) and the median of follow-up period was 6.68 years. RESULTS Thirty-five (85.4%) patients underwent transsphenoidal surgery as first treatment option. Histopathological evidence of a pituitary adenoma was registered in 17 (48.5%) patients. Thirty-two (78%) patients achieved disease remission after the first treatment, 21 (65.6%) of them presented disease recurrence. Persistent disease was observed in 9 (22%) patients. Twelve (29.3%) subjects developed post-surgical adrenal insufficiency, 7 of which (70%) achieved stable remission. Two parameters were found to be significant predictors of remission after the first treatment: age at disease diagnosis and the development of adrenal insufficiency (cortisol <3 μg/dl) in the immediate post-operative state. CONCLUSIONS We report a high recurrence rate, at least partially attributable to the long follow-up time. Early post-surgery adrenal insufficiency predicts remission. Hypopituitarism was also very prevalent, and strongly associated with radiotherapy. These results lead us to the conclusion that CD needs a life-long strict follow-up.

Abstract
Advances in endoscopic endonasal skull base surgery have led to the development of new routes to areas beyond the midline skull base. Recently, feasible surgical corridors to the lateral skull base have been described. The aim of this study was to describe the anatomical exposure of the ventrolateral brainstem and posterior fossa through an extended endoscopic endonasal transclival transpetrosal and transcondylar approach. Six human heads were used for the dissection process. The arterial and venous systems were injected with red- and blue-colored latex, respectively. A pre- and postoperative computed tomography (CT) scan was carried out on every head. The endoscopic endonasal transclival approach was extended through an anterior petrosectomy and a medial condylectomy. A three-dimensional model of the approach was reconstructed, using a dedicated software, from the overlapping of the pre- and post-dissection CT imaging of the specimen. An extended endoscopic transclival approach allows to gain access through an extradural anterior petrosectomy and medial condylectomy to the anterolateral surface of the brainstem and the posterior fossa. Two main intradural anatomical corridors can be described: first, between the V cranial nerve in the prepontine cistern and the VII-VIII cranial nerves in the cerebellopontine and cerebellomedullary cistern; second, between the VII-VIII cranial nerves and the IX cranial nerve, in the premedullary cistern. Extending the transclival endoscopic approach by performing an extradural anterior petrosectomy and a medial condylectomy provides a safe and wide exposure of the anterolateral brainstem with feasible surgical corridors around the main neurovascular structures.

Abstract
The case is presented of a 51 year-old woman, proposed for endoscopic endonasal transsphenoidal resection of a hypophyseal macroadenoma diagnosed in the context of a stroke suffered 10 weeks before the date of the surgery. During this time, she had been treated with antiplatelet drugs, which were withdrawn 5 days before the surgery. The surgical procedure was performed without any incidents. On the second day after the surgery, the patient had an ischaemic infarction of the left cerebellar hemisphere, with signs of hydrocephaly and a posterior haemorrhagic transformation, with brain death 5 days after the operation. There are no definitive guidelines on the use of antiplatelet drugs in the perioperative period of neurosurgery. Also, there is no agreement as regards the waiting time between a cerebrovascular event and surgery, it appears that between 4 and 12 weeks would be the most advisable. The importance of an individual assessment of each patient before surgery is emphasised, as well as a review of the antiplatelet management of the patient with a risk of thrombosis in the context of neurosurgery, and their possible postoperative complications.

Abstract
OBJECTIVE To describe the use, utility, safety, and effectiveness of the Proseal laryngeal mask for airway management in patients undergoing ventriculoperitonea shunting. PATIENTS AND METHODS We retrospectively reviewed the records of all patients in whom the Proseal laryngeal mask was used during ventriculoperitoneal shunting between January 2006 and October 2009. Patient demographic characteristics, airway assessments, type of anesthesia, quality of ventilation, and perioperative complications were recorded. RESULTS Of the 43 patients included, 8 (18.6%) had at least 1 difficult airway criterion. We were able to insert the Proseal laryngeal mask in all patients. Ventilation was optimal in 39 (91%) patients, with maintenance of end-expiratory carbon dioxide pressures between 35 and 40 mm Hg and airway pressures above 25 cm H2O throughout the procedures. Air leaks developed in 3 cases (7%) when the patient was placed in a lateral-cervical position for surgery; these patients required orotracheal intubation before surgery could begin. Mean duration of surgery was 53 minutes. Awakening occurred without incident in all cases. CONCLUSIONS The Proseal laryngeal mask is useful for airway management in patients undergoing ventriculoperitoneal shunting. Due to the forced position of the neck, however, it may be necessary to reposition the mask or even proceed to orotracheal intubation in some cases. As is the case for other advanced uses, experience with the device is necessary. Material for managing a difficult airway should be on hand.

Abstract
Lesions in the clivus and suprasellar region are rare but challenging pathologies for physicians. The most common tumours are chordomas and chondrosarcomas, but a wide variety of histopathological tumours can be found in these areas. Their deep location in the midline and their close relationship to important neurovascular structures frequently make total removal difficult. Neurosurgeons are often required to perform aggressive external-approach surgical therapy, which is usually associated with high levels of morbidity and a discouraging tendency for recurrence during long-term follow-up. Fortunately, over the past few years, close collaboration between otorhinolaryngologists and neurosurgeons has led to the development of minimally invasive surgery along the entire neuraxis, with endoscopy being used as the primary visualisation tool. This has been further augmented by the concept of team surgery: ENT surgeons and neurosurgeons working simultaneously throughout all phases of the surgery (approach, resection, and reconstruction). This concept has also changed the surgical approach as a whole, making the endonasal route the main approach for treating these types of lesions in carefully selected patients and external approaches the second-place option. The endonasal approach has revolutionised skull base surgery as it enables less aggressive surgery (reaching deep-seated structures without the need for craniotomy and brain retraction). It is therefore associated with lower morbidity and an absence of visible scars, with encouraging initial oncological prognosis. The aims of this paper are to describe the anatomical landmarks for this approach, to relate our experiences and to provide a literature review.

Abstract
OBJECTIVE The authors' objective is to report the initial appreciations on the use of the intraoperative near-infrared indocyanine green videoangiography during aneurysm surgery in our center. METHOD 10 surgical procedures have been made in 9 patients, 5 males and 4 females between 27 and 61 years old with an average of age of 49 years during a time of 10 months between March, 2008 and January, 2009. 10 surgical procedures were performed and 11 aneurysms were clipped. Intravenous indocyanine green and surgical microscope Leica OH4 with module of vascular fluorescence intraoperating Leica FL800, with camera infrared Sony (Heerbrugg-Switzerland) were used. The information offered by this technique during the intervention is compared with the images of the postoperative angiography performed during the first 24 hours. The partial or complete occlusion and the respect to the near vessels were evaluated. RESULTS The findings of the intraoperative videoangiography were the complete occlusion and absence of complications in all the cases. These results corresponded completely with the postoperative results of the angiography postoperative, except in a case where the angiography demonstrated vasoespasmo moderate without clinical repercussion that during the videoangiografía intraoperatoria was not perceived. Clinically no patient presented neurological added deficits. CONCLUSIONS The intraoperative videoangiography is a tool of easy application that offers valuable information as for the complete occlusion of the aneurysm and the permeability of the adjacent vessels.

Abstract
OBJECTIVE Compare the standard transsphenoidal sublabial microscopic approach with the endoscopic transsphenoidal approach concerning the tumoral invasiveness and resection, complications of the approaches and time of post operative hospitalisation. MATERIAL AND METHODS We realized a prospective, non randomised study with 50 patients. They were operated between 2002 and 2006. All the patients had sellar lesions with different grades of invasiveness of the cavernous sinus as classified by Knosp. The variables included in our study were tumoral invasiveness and operative resection (total, subtotal and partial), optic nerve lesion, postoperative panhypopituitarism, CSF fistula, cranial nerves deficits, epistaxis, meningitis, diabetes insipidus and carotid artery lesion. Our series included 27 males and 23 females ranging from 19 to 80 years old (48 mean). In 23 patients we used the standard sublabial microscopic approach (two patients were excluded) and for 25 patients we used the endoscopic approach. The mean follow up was of 12 months. RESULTS In our experience the endoscopic technique presents a higher percentage of total resection comparing to the sublabial microscopic approach (60% versus 34.8%) and higher percentage of subtotal resections (32% versus 26%) with a statistical significant difference (p=0.033). The time of hospitalisation was significant shorter for the endoscopic approach group (p=0.001), diminishing by half of the time (3 days) of the microscopic approach group. Concerning the tumoral invasiveness and complications we did not appreciate any significant dissimilarity. We appreciated that a higher grade of invasiveness augments by 3.59 the risk of an unsuccessful surgery. DISCUSSION AND CONCLUSION In our experience the endoscopic technique may favour a better tumoral resection and shorter time of hospitalisation. We did not appreciate differences concerning the complications.

Abstract
INTRODUCTION The incidence of neurocysticercosis (NCC) is increasing currently in developed countries due to the migration movements from endemic countries. Due to NCC polymorphism, treatment would be individualized in each case. Countries not used to this disease have to deal with. GOALS To set up diagnostic and therapeutic guidelines in all sorts of NCC and choose the correct treatment would be challenging. PATIENTS AND METHODS To perform a descriptive and retrospective analysis of six cases of NCC seen in the Neurosurgery Department of the Hospital Clinic de Barcelona from 1992 to 2000 (both included). We have performed a revision of the literature about diagnostic and therapeutic methods. DISCUSSION Definitive or probable diagnosis of NCC is based on clinical, imaging, immunological, and epidemiological criteria. In patients with inactive disease only symptomatic treatment is indicated. In active parenchymal forms there are not consensus if antiparasitic treatment is indicated. However, in extraparenchymal active disease aggressive treatment with antiparasitic agents and steroids is recommended. In cases of intracranial hypertension, neurological deficits or hydrocephalus surgery is the treatment of choice.

Abstract
OBJECTIVE To evaluate our experience regarding the treatment of pituitary macroadenomas with cavernous sinus invasion in a series of 23 cases of transphenoidal resection. MATERIALS, METHODS AND RESULTS Twenty two patients, fifteen males and seven females, with ages ranging from 27 to 75 (mean of 48), were operated under protocol by a single surgeon between May of 2002 and December of 2004. Preoperatively all lesions were diagnosed by MRI and staged according to the Knosp classification. All tumors had extension to one or both cavernous sinuses. Four patients were considered to be grade 1, two grade 2, one grade 3 and sixteen grade 4. Twenty three operations were performed on twenty-two patients. Twenty cases were the standard transsphenoidal approach, and three were endoscopic. Postoperatively, the excision was classified as Complete or Total, Subtotal or Partial. Mean follow up was 15 months. The variables considered for analysis include invasion and resection grades. All six patients with graded 1 and 2 lesions and two patients with grade 4 lesions underwent a complete resection. Subtotal (greater than 80%) excision was achieved in one patient with a grade 3 tumor and six patients with grade 4 tumors. The remaining seven patients with grade 4 adenomas had a Partial (less than 80%) excision. We compare de resection grade versus invasion grade with exact Fisher test. And there is not estadistical difference (p=0.12). CONCLUSION The Knosp classification alone cannot predict the behavior of these tumors. In our experience, despite tumor extension to the cavernous sinus, pituitary macroadenomas can be safely resected with low morbidity and mortality.
