ABSTRACT
El estesioneuroblastoma es una neoplasia maligna que se origina del epitelio olfatorio. El tratamiento se establece de acuerdo con su extensión y el grado histológico de atipia y puede incluir cirugía, cirugía más radioterapia o más radioquimioterapia. Se han utilizado diferentes abordajes quirúrgicos que incluyeron incisiones faciales y craneotomía pero, con la mayor experiencia adquirida en cirugía endoscópica de senos paranasales y el trabajo en equipo con el neurocirujano, se han desarrollado técnicas endonasales que posibilitan realizar resecciones oncológicas en pacientes seleccionados, con menos morbilidad, internación breve y sin comprometer el control local de la enfermedad. Describimos el caso clínico de una paciente con un estesioneuroblastoma con invasión intracraneal, que fue tratada con éxito mediante una hemicraniectomía endonasal preservando el bulbo olfatorio contralateral.

Esthesioneuroblastoma is a malignant neoplasm that originates from the olfactory epithelium. Treatment is established according to its extension and the histological degree of atypia and may include surgery, surgery more radiotherapy or more chemoradiation therapy. Different surgical approaches have been used, including facial incisions and craniotomy, but with the greater experience acquired with endoscopic sinus surgery and teamwork with the neurosurgeon, endonasal techniques have been developed that make it possible to perform oncological resections in selected patients, with less morbidity, brief hospitalization and without compromising local control of the disease. We describe the clinical case of a patient with an esthesioneuroblastoma with intracranial invasion who was successfully treated by endonasal hemicraniectomy preserving the contralateral olfactory bulb.

Herpes Simplex Encephalitis is the commonest form of sporadic encephalitis. Availability of effective antiviral therapy viz Acyclovir has significantly reduced the mortality of Herpes Simplex Encephalitis. Elevated intracranial pressure resulting in herniation syndromes continues to be an important cause of mortality. Antiviral therapy and medical measures for managing raised intracranial pressure including osmotic diuretics, careful usage of steroids and controlled hyperventilation continue to be the cornerstones in management of these patients. Authors present a 38-year-old male patient with Cerebrospinal fluid Meningo-encephalitic panel positivity for herpes simplex virus 1 and bilateral temporal lobe lesions with secondary decline due to impending herniation syndrome despite osmotic diuretics and steroids with patient survival and complete recovery following decompressive hemicraniectomy.
ABSTRACT
@#Background & Objectives: Malignant middle cerebral artery (MCA) stroke constituting 5% of all strokes carries a high mortality across the world. We aimed to study predictors of malignant MCA stroke outcome, especially decompressive surgery in a developing country scenario. Methods: This was a prospective study design where patients with malignant MCA stroke (defined as imaging-CT/ MRI showing infarct involving >2/3rd MCA territory) admitted within 7 days of illness to SCTIMST, between January 2010 and December 2014 (5 years) were recruited. Clinical and imaging data, surgical details, in hospital complications and discharge outcome were collected. Follow-up data was collected at 3 and 12 months post-stroke. Results: We had 74 patients of malignant MCA territory strokes, 42 operated and 32 non-operated, who were comparable at baseline, except for age and stroke severity. At 3 months, deaths were more among the non-operated group (63% in non-operated vs 23% in operated group, p=0.02), while functional outcome was comparable. At 1 year follow-up, age below 60 years, lower stroke severity at onset and decompressive surgery were found to be independent predictors of good outcome. (p=0.04). Delayed surgery group, albeit small had a better 1 year outcome in comparison to the medical arm. Conclusions: Early functional outcome in the decompression group did not differ from the medically treated patients, other than mortality benefit. However, at 1 year, patients with age<60 years, lower stroke severity and decompressive surgery had a better morbidity and mortality outcome, indicating long term benefit of this life saving procedure in developing country scenario as well.

ABSTRACT
OBJECTIVE: The authors applied maximum external decompression for malignant hemispheric infarction and investigated the functional outcome according to the patient age.METHODS: Twenty-five patients with malignant hemispheric infarction were treated using a hemicraniectomy with maximum external decompression, comprising a larger (>14cm) hemicraniectomy, resection of the temporalis muscle and its fascia, spaciously expansive duraplasty, and approximation of the skin flap. The medical and diagnostic imaging records for the patients were reviewed, and 1-year functional outcome data obtained for the younger group (aged ≤ 60 years) and elderly group (aged > 60 years).RESULTS: The patients (n=25) who underwent maximum surgical decompression revealed a minimal mortality rate (n=2, 8.0%). The patients (n=14) in the younger group all survived with mRS scores of 2 (n=1, 7.1%), 3 (n=7, 50.0%), 4 (n=3, 21.4%), or 5 (n=3, 21.4%). A majority of the younger patients (57.1% with mRS ≤3) lived with functional independence. When the 1-year mRS scores were dichotomized between favorable (mRS ≤3) and unfavorable (mRS ≥4) outcomes, the younger group had significantly more patients with a favorable outcome than the elderly group (57.1% versus 9.1%, p=0.033). In contrast, in the elderly group, most patients showed unfavorable outcomes with the mRS scores of 4 (n=5, 45.5%), 5 (n=3, 27.3%), or 6 (n=2, 18.2%), whereas only one patient showed favorable outcome (mRS 3). A majority of the elderly patients (45.5% with mRS 4) survived with moderately severe disability.CONCLUSION: For malignant hemispheric infarction, a hemicraniectomy with maximum external decompression was found to considerably increase survival with a favorable outcome in functional independence (mRS ≤3) for younger patients aged ≤60 years. It can be optimal surgical treatment for younger patients.

ABSTRACT
Background: Mass effect is the major cause of death in cortical venous sinus thrombosis and there is no clear cut the role of decompressive hemicraniectomy. Aims: To study the outcome of patients with large venous infarct and acutely increased intracranial pressure subjected to either conservative treatment or decompressive surgery. Materials & Methods: 20 consecutive patients admitted with moderate to large venous infarct were examined for features of raised intracranial pressure (ICP) . Cranial CT and or MRI and CT venogram or MR venogram and or cerebral DSA were examined for site of Sino venous occlusion. Results: There were 20 patients with 10 each in conservatively and surgically treated group. Cranial CT/MRI head revealed large venous infarct with midline shift and mass effect in all patients. Overall 15 of 16 survivors had good outcome at 3 months without any significant residual deficit irrespective of mode of treatment used. There is no statistical difference between medical and surgical groups in mRS 1 month, 3 months and death with p value 0.651, 0.185 and 0.474 respectively. Conclusion: Patient with large venous infarct with signs of raised intracranial pressure carries good overall outcome with timely care irrespective of conservative or surgical management.
ABSTRACT
BACKGROUND AND PURPOSE: The use of decompressive hemicraniectomy (DHC) for the treatment of malignant cerebral edema can decrease mortality rates. However, this benefit is not sufficient to justify its use in elderly patients. We investigated the effects of therapeutic hypothermia (TH) on safety, feasibility, and functional outcomes in elderly patients with malignant middle cerebral artery (MCA) infarcts. METHODS: Elderly patients 60 years of age and older with infarcts affecting more than two-thirds of the MCA territory were included. Patients who could not receive DHC were treated with TH. Hypothermia was started within 72 hours of symptom onset and was maintained for a minimum of 72 hours with a target temperature of 33°C. Modified Rankin Scale (mRS) scores at 3 months following treatment and complications of TH were used as functional outcomes. RESULTS: Eleven patients with a median age of 76 years and a median National Institutes of Health Stroke Scale score of 18 were treated with TH. The median time from symptom onset to initiation of TH was 30.3±23.0 hours and TH was maintained for a median of 76.7±57.1 hours. Shivering (100%) and electrolyte imbalance (82%) were frequent complications. Two patients died (18%). The mean mRS score 3 months following treatment was 4.9±0.8. CONCLUSIONS: Our results suggest that extended use of hypothermia is safe and feasible for elderly patients with large hemispheric infarctions. Hypothermia may be considered as a therapeutic alternative to DHC in elderly individuals. Further studies are required to validate our findings.

El ataque cerebrovascular (ACV) isquémico en la infancia es una entidad poco común que se ha venido incrementando en frecuencia y representa una patología de alto riesgo de eventos adversos en los niños; adicionalmente, es una patología de difícil manejo y con múltiples recurrencias. Los pacientes pediátricos que presentan esta clase de patología y que llegan al servicio de urgencias pediátricas son difíciles para establecer un diagnóstico e instaurar un manejo rápido, ya que esta entidad presenta múltiples diagnósticos diferenciales y por su baja incidencia no se tienen algoritmos claros y terapias rápidas y seguras para contrarrestar el compromiso neurológico severo del paciente. Esto se debe a que existen pocos estudios realizados en ACV pediátrico que describan el manejo médico adecuado o las intervenciones necesarias en esta patología, por lo cual no se tienen pautas claras para contrarrestar el evento agudo. Por lo tanto, se tienen intervenciones como trombectomía y la hemicraniectomia decompresiva, lo que lleva al paciente pediátrico a un riesgo mayor, pero tienen respuesta favorable en la mortalidad, con una recuperación favorable. Presentamos el caso clínico de un paciente pediátrico con ACV de territorio de arteria cerebral media derecha, su diagnóstico y tratamiento definitivo, con revisión de la literatura.
Ischemic stroke (CVA) in childhood is a rare entity that has been increasing in frequency and pathology represents a high risk of adverse events in children, additionally it is a pathology difficult to handle and with multiple recurrences. Pediatric patients with this kind of pathology and reaching the pediatric emergency department are difficult to establish a diagnosis and a fast management, since this entity has multiple differential diagnoses and their low incidence does not have clear algorithms and therapies fast and safe to counteract the severe neurological compromise patient. Because there are few studies in pediatric stroke describing the appropriate medical management or interventions for this disease, for which there are no clear guidelines to counteract the acute event. Therefore, there are interventions such as thrombectomy and decompressive craniectomy, leading to pediatric patients at a higher risk, but they have a favorable response in mortality, with a favorable recovery. We report a case of a pediatric patient with stroke in the territory of the right middle cerebral artery, diagnosis and definitive treatment, with review of the literature.

A large ischemic stroke caused by malignant middle cerebral artery infarction can lead to severe cerebral edema, even cerebral hernia. This condition deteriorates and progresses rapidly, usually leading to death. Due to limitations of conservative treatments, decompressive hemicraniectomy becomes a favored option in clinic. Recent years, a series of ex?perimental studies and clinical trials achieved reliable evidence that decompressive hemicraniectomy is an effective treat?ment for patients who suffer from malignant middle cerebral artery infarction. With the successful surgical procedure, most patients benefit from a reduced mortality and improved functional outcome without severe disability. Nevertheless, plenty of issues about decompressive hemicraniectomy still need to be solved. Here, we reviewed researches of early diagnosis of ma?lignant middle cerebral infarction and the application of decompressive hemicraniectomy as its treatment.

ABSTRACT
OBJECTIVE: This study is aimed to describe our experience with performing hemicraniectomy for treating patients with malignant cerebral infarction. This study also aimed at describing the difference between our experience and that of the published articles. METHODS: Ten patients who had anterior circulation territory cerebral infarction underwent decompressive hemicraniectomy for treating their life threatening brain swelling between August 2004 and October 2007. We retrospectively analyzed the patients' medical records and radiological films and we described the patients' clinical and radiological details. The outcomes were measured according to the case fatality rate at 2 weeks and the modified Rankin scale (mRS) at 9 months. We compared our institution's outcomes with the pooled analysis result of three randomized controlled trials (DESTINY, DECIMAL, HAMLET trial). RESULTS: Nine men and one woman were included in this study. Their mean age was 61.5 +/- 11.9 years, and the mean National Institute of Health Stroke Scale (NIHSS) score on admission was 17.3 +/- 6.0. Five patients died within 2 weeks after operation. Four patients had a mRS of 5 and one had a mRS of 4 at 9 months. Our series included elder patients (mean difference : 9.9~18.3 years) who had a low NIHSS score on admission (mean difference : -4.8~-6.8) as compared to that of the pooled analysis group. Our series revealed a higher proportion of an unfavorable outcome (mRS > or = 4) compared to that of the pooled analysis results (p=0.01). No patient in our series would have been eligible, according to the inclusion criteria, for inclusion in the pooled analysis studies. CONCLUSION: We think that the higher proportion of an unfavorable outcome in our series was a consequence of the elder age of our patients.

Twenty one patients were submitted to decompressive craniectomy for massive cerebral infarct. Ten patients (47.6 percent) presented a good outcome at the 6 months evaluation, eight had a poor outcome (38 percent) and three died (14.2 percent). There was no outcome statistical difference between surgery before and after 24 hours of ictus, dominant and non-dominant stroke groups. Patients older than 60 years and those who had a Glasgow Coma Scale (GCS)<8 in the pre-surgical exam presented worst outcome at six months (p<0.05). Decompressive craniectomy for space-occupying large hemispheric infarction increases the probability of survival. Age lower than 60 years, GCS >8 at pre-surgical exam and decompressive craniectomy before signs of brain herniation represent the main factors related to a better outcome. Dominant hemispheric infarction does not represent exclusion criteria.
Vinte e um pacientes foram submetidos a craniectomia descompressiva para o tratamento de infarto cerebral extenso. Dez pacientes (47,6 por cento) apresentaram boa evolução em avaliação após 6 meses, 8 apresentaram evolução desfavorável (38 por cento) e 3 faleceram (14,2 por cento). Durante o seguimento, não se evidenciou diferença estatística na evolução entre pacientes operados antes e após 24 horas do ictus, nem entre lesões envolvendo o hemisfério dominante versus não dominante. Pacientes com mais de 60 anos e aqueles com Escala de Coma de Glasgow (ECG)<8 na avaliação pré-operatória apresentaram pior evolução após 6 meses (p<0,05). A craniectomia descompressiva para infartos hemisféricos extensos aumentam a probabilidade de sobrevivência. Idade abaixo de 60 anos e ECG >8 no exame pré-operatório e craniectomia descompressiva antes de sinais de herniação cerebral representam os principais fatores relacionados a uma melhor evolução clínica. Infarto hemisférico envolvendo o hemisfério dominante não representa um critério de exclusão.

About 15% of the patients with the middle cerebral artery or internal carotid artery territory acute infarction can lead to massive cerebral edema with raised intracranial pressure and progression to coma or death within 3-5 days of the original ictus. Decompressive wide unilateral frontotemporoparietooccipital craniectomy with duroplasty should be given in appropriate time if patient had no effect in combating transtentorial herniation with medical therapy such as mannitol and hyperventilation. Occlusion of posterior inferior cerebellar artery or vertebral artery and superior cerebellar artery can evolve into life-threatening brainstem compression or hydrocephalus from postinfarct cerebellar edema. Suboccipital decompressive craniectomy with resection of necrotic cerebellar tissue or extraventricular drainage may be an effective lifesaving procedure in case of no improvement with medical therapy. Very few cases of acute infarction with embolic occlusion of main trunk of middle cerebral artery which confirmed by angiography within 6-8 hours after onset may be considered to have embolectomy by open craniotomy.
