RESUMO
La ultrasonografía es un método de evaluación rápido y eficaz en los departamentos de emergencias, siempre en manos entrenadas. La lesión vascular periférica es un cuadro que en lo que trauma se refiere, debe tener un veloz diagnóstico y tratamiento por los riesgos que significa: En lesiones abiertas, la hemorragia; y en lesiones cerradas se añade el síndrome compartimental. Lograr la evaluación de la indemnidad o no del árbol vascular en los miembros, se torna importante a la hora de prevenir eventos que requieran intervención quirúrgica (reparación y/o fasciotomía). El objetivo de este trabajo consiste en demostrar la utilidad del conocimiento del árbol vascular periférico y su evaluación mediante doppler para el manejo del trauma vascular periférico, mental (n=77) = 11 (14,78 %). Resolución: lesión vascular = 1 (1,3 %) síndrome compartimental= 1 (1,3 %) con resolución quirúrgica. La utilización de la ultrasonografía y del doppler para la evaluación vascular periférica es útil para el reconocimiento precoz del riesgo a desarrollar desde una lesión vascular simple hasta un síndrome compartimental. La utilización de listas de verificación durante la simulación para la generación del criterio, son útiles en la formación de residentes de cirugía
Report the recurrence rate ofnegative pressure subdural drainage (NPSD) versusto other kind of drains (OD). Design and Methods: Astudy was conducted cross-sectional and weretrospectively analyzed on the database of theneurosurgical service and we looked for all surgicalprocedures recorded from January 2006 to December2015. Procedures with preoperative diagnosis ofsubdural hematoma (SDH) were selected, with a to-tal of 364 interventions, were excluded patients withpostoperative diagnosis different from SDH andeliminated those who did not have complete data,recurrence was identified, a statistical analysis wasperformed describing frequency measurementspercentage and standard deviation, RM and chi-square was obtained by software EPIDAT 3.1. 277 surgeries were performed in 230 patients, Thepopulation was divided into two groups: the first thoseinterventions with negative pressure subduraldrainage versus a second group with other differentdrains, and finally we compared the recurrence ratein each group, 44 surgeries had recurrence of SDH.The proportion of recurrence was found 16 % of thesurgeries, 16 % (n=7) of these were performed withnegative pressure subdural drainage and theremaining 84 % (n=37) by other drainage. The reasonfor prevalence found was 0.36 (95 % CI , 0.15 to0.85), with statistically significant differences (p =0.0165). The chi-square was 5.75 for the SDH withNPSD. It was found that patients treated with NPSDhave a lower risk of recurrence compared with OD,which acts as a protective factor for patients treatedwith this type of drain, this is statistically significant.

INTRODUCTION: Schwannomas are benign tumours that are relatively common in the head, however the involvement of the sinunasal region is rare and there are only 5 cases reported in the maxilla in current literature, representing less than 1% of bone tumours. CLINICAL CASE: We report the case of a woman with a right maxillary schwannoma who underwent a complete resection of the lesion. Emphasis is placed on the rarity of the lesion in terms of its location and includes a review of clinical behaviour, diagnosis and current treatment options. CONCLUSIONS: Maxillary trigeminal schwannoma must be suspected if vague sinunasal symptoms, paranasal mass or, as in this case, trigeminal neuralgia present. Surgical treatment is indicated, and approaches vary according to location and tumour size.

El objetivo del trabajo fue escribir la técnica quirúrgica y reportar la experiencia de nuestro hospital en el uso del abordaje pterional modificado como primera elección para el clipaje de aneurismas del círculo arterial cerebral en cualquier ubicación e incluso múltiples. Realizamos un estudio retrospectivo y reportamos una serie de 37 pacientes (25 mujeres y 12 hombres) con diagnóstico de aneurismas derivados del círculo arterial cerebral de distintas ubicaciones, desde enero del 2012 hasta marzo del 2015. Se presenta la experiencia de 51 aneurismas incluidos 8 casos de aneurismas múltiples y 9 aneurismas gigantes.Todos los aneurismas fueron clipados mediante un abordaje pterional modificado. Se describieron yesquematizaron los pasos del procedimiento quirúrgico secuencialmente. Mediante este análisis se estableceque el abordaje frontotemporoesfenoidal modificado (pterional) permite el acceso quirúrgico para el clipajede estas lesiones vasculares provenientes del círculo arterial cerebral lo cual correlaciona con la evidencia previa. La descripción detallada de la técnica quirúrgica favorece una adecuada comprensión de la anatomía quirúrgica y permite la reproducción de esta técnica.
The objective of the study was to describe our surgical and technical experience by reporting a series of 51 aneurysms treated by a pterional craniotomy as a unique approach foraneurismatic lesions of the cerebral arterial circle (Willis polygon). Retrospective study that reportsa series of 37 patients (25 females and 12 males) with diagnosis of aneurismatic lesions from different localization in the Willis polygon from January 2012 to March 2015. Fifty one (51)aneurismatic lesions were treated by a unique pterional craniotomy, including 8 cases of multiple aneurismatic disease and 9 giant aneurysms. Every lesion was clipped by the same pterional modified approach. Every step of this procedure was described and illustrated sequentally. This analysis establishes that the modified fronto temporoesfenoidal (pterional) craniotomy allows surgical access to the clipping of these vascular lesions, from the circle of Willis which correlates with previous evidence. The detailed description of the surgical technique promotes a proper understanding of surgical anatomy and allows playback of this technique.
