Momento quirúrgico apoyado con doppler transcraneal en pacientes con hemorragia subaracnoidea aneurismática / Surgical timing supported by transcranial doppler in patients with subarachnoid hemorrhage from aneurisms rupture

Introducción: La cirugía de la hemorragia subaracnoidea aneurismática (HSA) realizada en las primeras 72 horas es beneficiosa. Cuando los casos arriban transcurrido este período el mejor momento quirúrgico es controversial. Objetivo. Evaluar la influencia sobre los resultados de la cirugía en la HSA de un protocolo para decidir el momento quirúrgico apoyado en el monitoreo con Doppler transcraneal (DTC). Material y Método: Se comparan los resultados quirúrgicos al alta y al año de seguimiento según la escala de Glasgow para resultados (EGR), en una serie de 233 casos con HSA rotos operados Enero de 2006 - Diciembre de 2010 y seguidos hasta Enero de 2012, en los que la cirugía en el período intermedio se decidió teniendo en cuenta las velocidades de flujo de los segmentos proximales del polígono de Willis registradas por DTC, con los de un grupo control histórico operado Diciembre de 1983 - Diciembre de 2005 sin la ayuda de dicho monitoreo. Resultados: La mortalidad al alta y al año en la serie de estudio fue de 4,3 y 4,5 por ciento y en el grupo control 7 y 7,7 por ciento respectivamente. Se observaron resultados satisfactorios (grados 4 y 5 en EGR) en el 93,1 al alta y 92,8 por ciento al año en la serie de estudio. Entre los controles históricos estos índices fueron 85,6 y 88,1 por ciento respectivamente (p = 0,004 y p = 0,036). Conclusiones: Los resultados del tratamiento microquirúrgico de la HSA se benefician con la atención protocolizada y la consideración de los resultados del DTC para seleccionar el momento quirúrgico.

Background: Aneurysmal subarachnoid hemorrhage (SAH) surgery, practiced in the first 72 hours is beneficial. The optimal surgical timing, for microsurgical clipping of ruptured intracranial aneurysms, remains controversial when patients arrive between 4 and 14 days. Some surgeons favor a prompt operation regardless the timing. Other ones prefer to wait 2 weeks. Most patients in developing countries are taken to neurosurgical attention late, which not permit an early surgery. Object. To evaluate the surgical outcome in a series of patients with subarachnoid hemorrhage (SAH) managed according to a dynamic protocol. Methods: The authors evaluated surgical outcome by means of Glasgow Outcome Scale (GOS) score in a series of 233 patients with SAH who received neurosurgical clipping in the years 2006-2010 and were followed until January 2012, whose surgical timing was decided according to transcranial Doppler (TD) monitoring. These outcomes were compared with results in a series of 445 historic controls operated 1983-2005. Results: Series mortality at the discharge and at the year were 4.3 and 4.5 percent, and 7 and 7.7 percent in the control group respectively. Series show good outcomes (grade 4 and grade 5 in GOS score) in 93.1 at the discharge and 92.8 percent at the year. Among the historic controls cases with good outcome were 85.6 and 88.1 percent respectively (p = 0.004 y p = 0.036). Conclusions: Surgical outcomes of SAH can be favored by the impact of protocolized attention and TD to decide the best surgical timing in SAH.

Resultados quirúrgicos de los pacientes con hemorragia subaracnoidea aneurismática que recibieron atenciónprotocolizada en el Hospital Hermanos Ameijeiras / Surgical results of patients with aneurismatic subarachnoid hemorrhage treated by protocolized approach in “Hermanos Ameijeiras” Hospital

Objetivo: Valorar las características basales de una serie de pacientes con hemorragia subaracnoidea aneurismática y el impacto sobrelos resultados quirúrgicos de un protocolo de manejo dinámico basado fundamentalmente en el ultrasonido Doppler transcraneal.Métodos: Se realizó un estudio descriptivo longitudinal en 233 pacientes con hemorragia subaracnoidea aneurismática operados en el Hospital Hermanos Ameijeiras durante el período 2006–2010 y evaluados posoperatoriamente por un año.Resultados: La edad media fue 49,19 años. El sexo femenino representó el 66 (Por ciento). Al ingreso, 58,4 (Por ciento) de los casos fueron grado 1 de laescala modificada de la FMSN. El estado preoperatorio evolucionó a 69,5 (Por ciento)en grado 1. El grado 3 de Fisher predominó y se asoció a la presencia de vasospasmo. El 28,8 (Por ciento) de los casos presentó vasospasmo angiográfico, elevándose el diagnóstico al 49,4 (Por ciento) con el DopplerTranscraneal, en el 25,8 (Por ciento) se hizo sintomático y el 15,9 (Por ciento) desarrolló déficit isquémico. El 73,4 (Por ciento) tuvieron aneurismas únicos de la circulación anterior. El 79,4 (Por ciento) de los aneurismas midieron entre 4–10 mm. La evolución fue favorable en el 93 (Por ciento) y la mortalidad fue de 4,29 (Por ciento). Los resultados al alta se relacionaron significativamente con: el estado al ingreso y preoperatorio, la escala de Fisher, el número de aneurismas, vasospasmo y resangramiento. Las complicaciones médicas y quirúrgicas más frecuentes fueron el vasospasmo, elresangramiento, el infarto cerebral, las infecciones urinarias, la hidrocefalia y la ruptura transoperatoria.Conclusiones: Los resultados fueron propicios comparados con la literatura especializada. Se evidenció la utilidad del manejo protocolizado y el uso de Doppler Transcraneal en estos pacientes(AU)

Objective: To assess basal characteristics and surgical outcome in patients with aneurismatic subarachnoid hemorrhage managed with one dynamic protocol based mostly on transcranial Doppler ultrasound.Methods: A descriptive longitudinal study was carried out in 233 patients with aneurismatic subarachnoid hemorrhages, who received neurosurgical clipping in the years 2006–2010 and were followed during one year.Results: Mean age was 49.19 years. Female were 66 (Per cent). At the admission, 58.4 (Per cent) of cases were in grade 1 according to the modified scale of World Federation of Neurosurgical Societies (WFNS). Preoperatively 69.5 (Per cent) of patients become grade 1. Patients were mostly Fisher 3 according to CT scan results, and this was statistically associated with vasospasm. Angiographic vasospasm was present in 28.8 (Per cent) of the cases, but increased to 49.4 (Per cent) by using transcranial Doppler. In 25.8 (Per cent) of cases vasospasm was symptomatic, and 15.9 (Per cent) develop delayed ischemic deficit. Single aneurysms on the anterior Willis circle were most relevant statistically and accounted for 73.4 (per cent) of the cases. Aneurysms were mostly of relatively small size, and in 79.4 (Per cent) of the patients they ranged between 4 and 10 mm. Outcome was favorable in 93 (Per cent), and mortality was 4.29 (Per cent). Outcome was significant associated with: neurological status at the admission, Fisher scale, numbers of aneurysms, vasospasm, and re–bleeding. Most frequents surgical and medical complications were vasospasm, re–bleeding, cerebral infarct urinary infection, hydrocephalus and intraoperative rupture.Conclusions: Compared with several series from specialized literature, outcome in this series was good. These suggest the utility of one dynamic protocol based on transcranial Doppler in patients with aneurismatic subarachnoid hemorrhage(AU)

Gigant transethmoidal meningoencephalocele operated by full endonasal endoscopic approach: case report.

Intranasal meningoencephaloceles have historically been managed by neurosurgeons, although their main clinical manifestations are rhinological. Recent advances in endoscopic skull base surgery has significantly improved the treatment of these lesions and consequently diminished appreciable surgical morbidity. We report an ethmoidal meningoencephalocele case operated on by endonasal endoscopic approach for removal of the lesion and reconstructing the associated skull base. From this experience, we conclude that removal of the lesion and watertight closure of the skull base irrespective of the size of the mass and anterior skull base defect are the operation's most important aspects.
