RESUMO
BACKGROUND AND OBJECTIVE: We aimed to evaluate the safety and outcomes of thrombectomy in anterior circulation acute ischaemic stroke recorded in the SITS-International Stroke Thrombectomy Register (SITS-ISTR) and compare them with pooled randomized controlled trials (RCTs) and two national registry studies. METHODS: We identified centres recording ≥10 consecutive patients in the SITS-ISTR with at least 70% of available modified Rankin Scale (mRS) at 3 months during 2014-2019. We defined large artery occlusion as intracranial internal carotid artery, first and second segment of middle cerebral artery and first segment of anterior cerebral artery. Outcome measures were functional independence (mRS score 0-2) and death at 3 months and symptomatic intracranial haemorrhage (SICH) per modified SITS-MOST. RESULTS: Results are presented in the following order: SITS-ISTR, RCTs, MR CLEAN Registry and German Stroke Registry (GSR). Median age was 73, 68, 71 and 75 years; baseline NIHSS score was 16, 17, 16 and 15; prior intravenous thrombolysis was 62%, 83%, 78% and 56%; onset to reperfusion time was 289, 285, 267 and 249 min; successful recanalization (mTICI score 2b or 3) was 86%, 71%, 59% and 83%; functional independence at 3 months was 45.5% (95% CI: 44-47), 46.0% (42-50), 38% (35-41) and 37% (35-41), respectively; death was 19.2% (19-21), 15.3% (12.7-18.4), 29.2% (27-32) and 28.6% (27-31); and SICH was 3.6% (3-4), 4.4% (3.0-6.4), 5.8% (4.7-7.1) and not available. CONCLUSION: Thrombectomy in routine clinical use registered in the SITS-ISTR showed safety and outcomes comparable to RCTs, and better functional outcomes and lower mortality than previous national registry studies.

PURPOSE: There is no established rescue treatment in patients with mechanical thrombectomy (MT) failure. Our aim is to analyse whether the use of an intracranial stent improves prognosis in these patients. METHODS: Retrospective analysis of a prospective cohort of patients with ischemic stroke due to middle cerebral artery occlusion (MCA) or distal intracranial carotid artery (ICA) occlusion, from September 2009 to April 2019 in our comprehensive stroke care centre. Patients with MT failure were identified and dichotomized into two groups according to whether or not an intracranial stent was implanted. We analysed clinical outcomes in both groups. RESULTS: There was MT failure in 60 patients (14%) of the 433 with large vessel occlusion in distal ICA and proximal MCA. A stent was placed in 20 of them (33.3%). Compared to patients without rescue stenting, they showed better rates of independence at 3 months (mRS ≤ 2) 45% vs 2.5% (p < 0.001) and lower mortality 15% vs 50% (p = 0.009), maintaining statistical significance after multivariate analysis, without a significant increase of the rate of symptomatic intracranial haemorrhage (p = 0.209). CONCLUSION: Placement of an intracranial stent as rescue therapy after MT failure was associated with better clinical outcome without significant increase in haemorrhagic complications. We believe that this procedure should be appraised in these patients.

BACKGROUND AND OBJECTIVE: To update the ad hoc Committee of the Cerebrovascular Diseases Study Group of The Spanish Neurological Society guidelines on prevention of ischaemic stroke (IS) and Transient Ischaemic Attack (TIA). METHODS: We reviewed the available evidence on ischaemic stroke and TIA prevention according to aetiological subtype. Levels of evidence and recommendation levels are based on the classification of the Centre for Evidence-Based Medicine. RESULTS: In atherothrombotic IS, antiplatelet therapy and revascularization procedures in selected cases of ipsilateral carotid stenosis (70%-90%) reduce the risk of recurrences. In cardioembolic IS (atrial fibrillation, valvular diseases, prosthetic valves and myocardial infarction with mural thrombus) prevention is based on the use of oral anticoagulants. Preventive therapies for uncommon causes of IS will depend on the aetiology. In the case of cerebral venous thrombosis oral anticoagulation is effective. CONCLUSIONS: We conclude with recommendations for clinical practice in prevention of IS according to the aetiological subtype presented by the patient.

INTRODUCTION: Update of Acute Ischaemic Stroke Treatment Guidelines of the Spanish Neurological Society based on a critical review of the literature. Recommendations are made based on levels of evidence from published data and studies. DEVELOPMENT: Organized systems of care should be implemented to ensure access to the optimal management of all acute stroke patients in stroke units. Standard of care should include treatment of blood pressure (should only be treated if values are over 185/105 mmHg), treatment of hyperglycaemia over 155 mg/dl, and treatment of body temperature with antipyretic drugs if it rises above 37.5 °C. Neurological and systemic complications must be prevented and promptly treated. Decompressive hemicraniectomy should be considered in cases of malignant cerebral oedema. Intravenous thrombolysis with rtPA should be administered within 4.5 hours from symptom onset, except when there are contraindications. Intra-arterial pharmacological thrombolysis can be considered within 6 hours, and mechanical thrombectomy within 8 hours from onset, for anterior circulation strokes, while a wider window of opportunity up to 12-24 hours is feasible for posterior strokes. There is not enough evidence to recommend routine use of the so called neuroprotective drugs. Anticoagulation should be administered to patients with cerebral vein thrombosis. Rehabilitation should be started as early as possible. CONCLUSION: Treatment of acute ischaemic stroke includes management of patients in stroke units. Systemic thrombolysis should be considered within 4.5 hours from symptom onset. Intra-arterial approaches with a wider window of opportunity can be an option in certain cases. Protective and restorative therapies are being investigated.

OBJECTIVE: To update the Spanish Society of Neurology's guidelines for subarachnoid haemorrhage diagnosis and treatment. MATERIAL AND METHODS: A review and analysis of the existing literature. Recommendations are given based on the level of evidence for each study reviewed. RESULTS: The most common cause of spontaneous subarachnoid haemorrhage (SAH) is cerebral aneurysm rupture. Its estimated incidence in Spain is 9/100 000 inhabitants/year with a relative frequency of approximately 5% of all strokes. Hypertension and smoking are the main risk factors. Stroke patients require treatment in a specialised centre. Admission to a stroke unit should be considered for SAH patients whose initial clinical condition is good (Grades I or II on the Hunt and Hess scale). We recommend early exclusion of aneurysms from the circulation. The diagnostic study of choice for SAH is brain CT (computed tomography) without contrast. If the test is negative and SAH is still suspected, a lumbar puncture should then be performed. The diagnostic tests recommended in order to determine the source of the haemorrhage are MRI (magnetic resonance imaging) and angiography. Doppler ultrasonography studies are very useful for diagnosing and monitoring vasospasm. Nimodipine is recommended for preventing delayed cerebral ischaemia. Blood pressure treatment and neurovascular intervention may be considered in treating refractory vasospasm. CONCLUSIONS: SAH is a severe and complex disease which must be managed in specialised centres by professionals with ample experience in relevant diagnostic and therapeutic processes.

INTRODUCTION: Endovascular therapies (intra-arterial thrombolysis and mechanical thrombectomy) after acute ischaemic stroke are being implemented in the clinical setting even as they are still being researched. Since we lack sufficient data to establish accurate evidence-based recommendations for use of these treatments, we must develop clinical protocols based on current knowledge and carefully monitor all procedures. DEVELOPMENT: After review of the literature and holding work sessions to reach a consensus among experts, we developed a clinical protocol including indications and contraindications for endovascular therapies use in acute ischaemic stroke. The protocol includes methodology recommendations for diagnosing and selecting patients, performing revascularisation procedures, and for subsequent patient management. Its objective is to increase the likelihood of efficacy and treatment benefit and minimise risk of complications and ineffective recanalisation. Based on an analysis of healthcare needs and available resources, a cooperative inter-hospital care system has been developed. This helps to ensure availability of endovascular therapies to all patients, a fast response time, and a good cost-to-efficacy ratio. It includes also a prospective register which serves to monitor procedures in order to identify any opportunities for improvement. CONCLUSIONS: Implementation of endovascular techniques for treating acute ischaemic stroke requires the elaboration of evidence-based clinical protocols and the establishment of appropriate cooperative healthcare networks guaranteeing both the availability and the quality of these actions. Such procedures must be monitored in order to improve methodology.

Intracerebral haemorrhage accounts for 10%-15% of all strokes; however it has a poor prognosis with higher rates of morbidity and mortality. Neurological deterioration is often observed during the first hours after onset and determines poor prognosis. Intracerebral haemorrhage, therefore, is a neurological emergency which must be diagnosed and treated properly as soon as possible. In this guide we review the diagnostic procedures and factors that influence the prognosis of patients with intracerebral haemorrhage and we establish recommendations for the therapeutic strategy, systematic diagnosis, acute treatment and secondary prevention for this condition.

BACKGROUND: Several clinical scales have been developed for predicting stroke recurrence. These clinical scores could be extremely useful to guide triage decisions. Our goal was to compare the very early predictive accuracy of the most relevant clinical scores [age, blood pressure, clinical features and duration of symptoms (ABCD) score, ABCD and diabetes (ABCD2) score, ABCD and brain infarction on imaging score, ABCD2 and brain infarction on imaging score, ABCD and prior TIA within 1 week of the index event (ABCD3) score, California Risk Score, Essen Stroke Risk Score and Stroke Prognosis Instrument II] in consecutive transient ischemic attack (TIA) patients. METHODS: Between April 2008 and December 2009, we included 1,255 consecutive TIA patients from 30 Spanish stroke centers (PROMAPA study). A neurologist treated all patients within the first 48 h after symptom onset. The duration and typology of clinical symptoms, vascular risk factors and etiological work-ups were prospectively recorded in a case report form in order to calculate established prognostic scores. We determined the early short-term risk of stroke (at 7 and 90 days). To evaluate the performance of each model, we calculated the area under the receiver operating characteristic curve. Cox proportional hazards multivariate analyses determining independent predictors of stroke recurrence using the different components of all clinical scores were calculated. RESULTS: We calculated clinical scales for 1,137 patients (90.6%). Seven-day and 90-day stroke risks were 2.6 and 3.8%, respectively. Large-artery atherosclerosis (LAA) was observed in 190 patients (16.7%). We could confirm the predictive value of the ABCD3 score for stroke recurrence at the 7-day follow-up [0.66, 95% confidence interval (CI) 0.54-0.77] and 90-day follow-up (0.61, 95% CI 0.52-0.70), which improved when we added vascular imaging information and derived ABCD3V scores by assigning 2 points for at least 50% symptomatic stenosis on carotid or intracranial imaging (0.69, 95% CI 0.57-0.81, and 0.63, 95% CI 0.51-0.69, respectively). When we evaluated each component of all clinical scores using Cox regression analyses, we observed that prior TIA and LAA were independent predictors of stroke recurrence at the 7-day follow-up [hazard ratio (HR) 3.97, 95% CI 1.91-8.26, p < 0.001, and HR 3.11, 95% CI 1.47-6.58, p = 0.003, respectively] and 90-day follow-up (HR 2.35, 95% CI 1.28-4.31, p = 0.006, and HR 2.20, 95% CI 1.15-4.21, p = 0.018, respectively). CONCLUSION: All published scores that do not take into account vascular imaging or prior TIA when identifying stroke risk after TIA failed to predict risk when applied by neurologists. Clinical scores were not able to replace extensive emergent diagnostic evaluations such as vascular imaging, and they should take into account unstable patients with recent prior transient episodes.

OBJECTIVE: To update the ad hoc Committee of the Cerebrovascular Diseases Study Group of The Spanish Neurological Society guidelines on prevention of ischaemic stroke (IS) and transient ischaemic attack (TIA). METHODS: We reviewed available evidence on risk factors and means of modifying them to prevent ischaemic stroke and TIA. Levels of evidence and recommendation grades are based on the classification of the Centre for Evidence-Based Medicine. RESULTS: This first section summarises the recommendations for action on the following factors: blood pressure, diabetes, lipids, tobacco and alcohol consumption, diet and physical activity, cardio-embolic diseases, asymptomatic carotid stenosis, hormone replacement therapy and contraceptives, hyperhomocysteinemia, prothrombotic states and sleep apnea syndrome. CONCLUSIONS: Changes in lifestyle and pharmacological treatment for hypertension, diabetes mellitus and dyslipidemia, according to criteria of primary and secondary prevention, are recommended for preventing ischemic stroke.

OBJECTIVE: To identify overuse (diagnostic, therapeutic and self-care practices that represent risks that outweigh the potential benefits) in patients with atrial fibrillation. METHOD: The study was based on qualitative research techniques. Using the "Metaplan" technique, we identified and ordered potentially inappropriate, ineffective and inefficient practices. By means of a consensus conference, we then established a number of "inadvisable practice" measures (relatively common practices that should be eliminated based on the scientific evidence or clinical experience). Professionals from the specialties of cardiology, haematology, neurology, internal medicine, family medicine and nursing participated in the consensus. RESULTS: We developed a catalogue of 19 "inadvisable practices" related to the diagnosis, treatment and care of anticoagulated patients that were inappropriate, had questionable effectiveness or were ineffective, as well as 13 beliefs or behaviours for anticoagulated patients that could result in injury or were useless or inefficient. CONCLUSION: The "inadvisable practices" approach helps identify practices that represent greater risks than benefits for patients. It seems appropriate to include algorithms in the clinical decision-making support systems that consider this information for the diagnosis, treatment and for home care. For this last case, recommendations have also been prepared that define specific contents for the healthcare education of these patients.
RESUMO
INTRODUCTION: Meningioma is one of the most frequent tumours affecting the central nervous system, with an estimated incidence of between 15 and 20% of all brain tumours. They are generally benign and slow growing. Their appearing as a cerebral infarction is very rare. CASE REPORT: A right-handed 75-year-old female patient with a personal history of arterial hypertension, who visited the Emergency Department because of the sudden onset of severe dysarthria, accompanied by loss of strength in the left limbs, supranuclear facial palsy on the left side and Horner syndrome on the right. A computerised tomography scan of the brain revealed a lacunar infarct in said location, with no other appreciable damage. The neurovascular study included a transcranial Doppler, which was unable to insonate the left vertebral artery or the basilar artery. Magnetic resonance imaging of the head revealed a foramen magnum meningioma, with vertebrobasilar vascular distortion. The patient progressed favourably and was submitted to radiosurgery. CONCLUSIONS: The case reported here is unique, since it describes a meningioma of the posterior fossa that appears in the form of the initial symptoms of a pontine stroke due to a vascular disorder.

BACKGROUND AND PURPOSE: We sought to study overall and domain-specific quality of life in stroke survivors 1 year after stroke and to identify variables that could predict quality of life after stroke. METHODS: We followed up for 1 year a cohort of 118 patients consecutively admitted to our stroke unit at San Carlos University Hospital in Madrid, Spain. The final series at 1-year follow-up consisted of 90 survivors (41 women and 49 men; mean age, 68 years; range, 32 to 90 years). A cross-sectional, descriptive design was developed. Patients completed a questionnaire that included socioeconomic variables, Hamilton Rating Scale for Depression, Sickness Impact Profile (SIP), Short Form 36, Frenchay Index, Barthel Index, Rankin Scale, and Scandinavian Stroke Scale. Independent variables were sex, age, functional status, motor impairment, and depression. We developed an ANOVA model for statistical analysis. RESULTS: We interviewed 79 patients with ischemic and 11 with hemorrhagic stroke. Thirty-eight percent of patients scored in the depressed range. Variables related to depression were status as a housewife, female sex, inability to work because of disability, and diminished social activity (P:<0.0001). Mean total SIP (24.3), SIP psychosocial dimension (27.5), and SIP physical dimension (21.2) were correlated with disability, female sex, motor impairment, and depression (P:<0.0001). CONCLUSIONS: Functional status and depression were identified as predictors of quality of life. Patients independent in their activities of daily living suffered from a deterioration of the psychosocial dimension of the SIP.

Takayasu's arteritis is an inflammatory disease that produces a narrowing of the aorta and its major branches. The transcranial doppler findings and its value have not been clearly determined. We describe a patient with a history of orthostatic syncopal attacks, and transitory ischemic attacks. Arteriography showed severe narrowings and occlusions of multiple large branches of the aortic arch. Transcranial doppler showed a low flow velocity in both middle cerebral arteries, low pulsatility index and damping in the waveform. After surgery, transcranial doppler ipsilateral to the graft became almost normal and the collateralization pattern had changed. This case provides further evidence that the Takayasu's arteritis leads to relevant changes in the transcranial doppler waveform and that this technique can help in the follow-up of these patients.

The ascending aortic dilatation and its dissection is a not very frequent finding in patients with Turner syndrome. The high incidency of structural anomalies in the aortic wall and the severity of its complications, makes it necessary to watch these patients very closely. We present an asymptomatic patient, affected with Turner syndrome, ascending aortic dilatation and aortic wall dissection.

INTRODUCTION: The treatment of stroke by thrombolysis or other methods (neuroprotection, basic care, etc.) is more effective the sooner it is begun. The main reasons for patients not receiving treatment during the acute phase of their illness are slowness in reaching hospital and delay in emergency assessment once they arrive there. It is necessary to identify the factors involved in these delays so as to modify what can be improved and establish guidelines. DEVELOPMENT: In the chain of events leading to arrival in hospital there are independent factors related to the social and health characteristics of the patients, their attitudes to illness, characteristics of the stroke itself and of the health district. Analysis of the system for response to stroke patients is extremely important before investing in measures to be applied during the acute phase. This analysis should be based on the different stages at which delays may occur. Outside the hospital, the systems to be recognized are those of the patient and his family, contact with prehospital care teams and transport to the hospital of reference. Hospital care involves making contact on arrival at the Emergency Department, and the response of the neurologist or stroke team who give the initial treatment. CONCLUSIONS: Programmes of education and improvement in the organization of the different protagonists at the various stages reduce the time lost by delay.

INTRODUCTION: A spontaneous cervical epidural hematoma is an infrequent cause of cord compression. The commonest clinical presentations are with paraparesia and tetraparesia. Transient hemiparesia is very rare and a sensory-motor syndrome is exceptional. CLINICAL CASE: A 38 year old man had sudden onset of spontaneous interscapular vertebral pain with bilateral root radiation. A few minutes later he started to have weakness and sensory loss in his right limbs. On clinical examination there was pain on pressure over the spinal apophyses of the T4 and T5 vertebrae, hemiparesia and hemi-hypoalgesia of the right limbs. After ten hours this had all returned to normal. MRI of the cord showed an epidural hematoma extending from C6 to T2. Coagulation studies and spinal arteriography were normal. CONCLUSIONS: The sensory motor syndrome is an unusual form of presentation of a spontaneous cervico-thoracic epidural hematoma. Root pain is a symptom of great value for orientation of a syndrome which would otherwise seem to be of central origin. The explanation for this clinical findings may be compression of both lateral cord pathways due to their particular blood distribution. Regarding therapeutic approach, this should be conservative, with close observation to see whether it will resolve spontaneously in a short period of time.

INTRODUCTION: The one and a half vertical syndrome consists of paralysis of upward vertical conjugated gaze and monocular paralysis of downward gaze or vice-versa. It occurs as a consequence of a mesencephalodiencephalic lesion, either unilaterally or bilaterally, due to effects on structures such as the interstitial nucleus of Cajal, posterior commissure and rostral interstitial nucleus of the medial longitudinal bundle. The arterial supply of the structures involved in the supranuclear control of vertical gaze depends on the paramedian thalamic arteries (or posterior thalamo-subthalamic arteries) and the paramedian peduncular arteries. CLINICAL CASE: We present the case of a 58 year old woman with non-insulin dependent diabetes mellitus who presented with sudden onset of diplopia of vertical gaze. On examination there was paralysis of superior vertical conjugated gaze and monocular paralysis of ocular infraversion (one and a half syndrome) with no other pathological findings. Cerebral angioresonance and Doppler studies of the territory supplied by the posterior cerebral artery were normal. CONCLUSIONS: Both unilateral and bilateral mesencephalodiencephalic infarcts usually present clinically as disorders of consciousness and of conduct (the almost universal form of presentation), involvement of the pyramidal tract, the third cranial nerves and a supranuclear disorder of vertical gaze. The unusual feature of the case we present is a bilateral thalamo-subthalamic infarct which presented solely as a one and a half vertical syndrome with no clinically apparent effect on anatomically adjacent structures. We have not found any similar cases in the literature.

The outcome in 195 patients admitted in a non-intensive stroke unit was compared to that in 198 patients admitted in general wards during a 12 months period. At admission, both groups were similar in prognostic indicators (age, sex, previous history, level of consciousness and motor impairment). Short-term mortality rates was reduced among patients admitted in stroke unit (p < 0.001). This difference was independent of patient's age, previous history and neurological impairment on admission. The length of stay in the hospital was also reduced (p < 0.001). Among survivors, functional outcome at discharge was better in those admitted in the stroke unit, with a greater proportion of patients independent for activities of daily living. We conclude that stroke unit in an efficient strategy that improves the clinical outcome of patients with acute stroke.
