Trombosis de seno venoso asociada con infección por SARS-CoV-2 / Cerebral venous thrombosis associated with SARS-Cov-2 infection

RESUMEN INTRODUCCION: La trombosis del seno venoso se considera una de las causas más infrecuentes de enfermedad cerebrovascular (ECV), prevalente en la edad joven. Suele tener un inicio insidioso, lo cual dificulta su diagnóstico y el inicio oportuno del tratamiento, y se encuentra asociada con múltiples factores de riesgo, incluyendo estados de hipercoagulabilidad, como en aquellos pacientes que cursan con infección por SARS-CoV-2. REPORTE DE CASO: Se presentan dos casos clínicos de pacientes con alteraciones neurológicas, diplopia y estatus epiléptico, en quienes se documentó por medio de la sintomatologia y de estudios imagenológicos, trombosis venosas extensas de localización infrecuente, se descartaron las principales etiologías asociadas, y el único nexo asociado fue la infección por SARS-CoV-2. Ambos pacientes recibieron tratamiento con anticoagulación parenteral, al que respondieron de forma exitosa, por lo cual se logró el alta posteriormente con anticoagulación oral. DISCUSIÓN: Es imprescindible el conocimiento de esta enfermedad, asociada con una alta sospecha diagnóstica, dadas sus manifestaciones clínicas variadas y su asociación cada vez más frecuente con infección por covid-19.

ABSTRACT INTRODUCTION: Venous sinus thrombosis is considered one of the most infrequent causes of cerebrovascular disease (CVD), prevalent in young people. It usually has an insidious onset which difficult its diagnosis and timely initiation of treatment and is associated with multiple risk factors including hypercoagulable states, as in those patients with SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) infection. CASE REPORT: The following are 2 clinical cases of patients with neurological alterations, diplopia, and status epilepticus, in whom extensive venous thrombosis of infrequent location was documented through symptomatology and imaging studies, ruling out the main associated etiologies, with the only associated nexus: SARS-CoV-2 infection. Both patients received treatment with parenteral anticoagulation, responding successfully and were subsequently discharged with oral anticoagulation. DISCUSSION: It is essential to be aware of this disease associated with a high diagnostic suspicion given its varied clinical manifestations and its increasingly frequent association with COVID-19 infection.

INTRODUCTION: the superior longitudinal sinus thrombosis is a disease difficult to detect because of its different causes and because of the polymorphism of its neurological manifestations; It is also common in females related to estrogen stimuli and other hormonal factors, but unlikely in younger than 40 years. PATIENT: a patient younger than 40 years after having two episodes of ischemic strokes, cognitive and functional status is assessed one year after the injury using the neuropsi battery attention and memory and the mayo-portland adaptability inventory; Cognitive processes affected at a slight level of classification were attention and concentration, executive functioning; In the functional status reported by the spouse suggests involvement of clinical symptoms such as irritability, anger, aggression, headaches, fatigue and reactions to minor symptoms and inadequate interaction, these symptoms were not reported by the patient suggesting possible anosognosia in her process of adaptability CONCLUSIÓN: After a process of brain injury due to thrombotic involvement, the cognitive and functional sequelae remain after spontaneous recovery, suggesting the import of rehabilitation processes.

Homocistinuria, reporte de un caso / Homocystinuria, Case Report / Homocistinuria, relato de um caso

Resumen: En este artículo se presenta el caso de una niña de 13 años con historia de cefalea de 2 años de evolución, la cual ha sido estudiada por subluxación del cristalino y fenotipo marfonoide. Para llevar a cabo la investigación se realizó una tomografía cerebral simple que evidenció trombosis de varios senos cerebrales. Posteriormente se hospitalizó a la paciente en la unidad de cuidados intensivos, mientras se anticoagulaba con enoxaparina. Se solicitó un estudio para trombofilia junto con homocisteina en sangre, ante la sospecha de homocistinuria. Luego de confirmarse el diagnóstico se recetó piridoxina y ácido fólico, con lo cual la paciente evolucionó de manera satisfactoria y recuperó las funciones perdidas. El seguimiento de este caso para la investigación permitió encontrar una disminución mayor del 20 % de la homocisteina, sin que sus niveles estuvieran por debajo de 50 µmol/L, hecho que hace a la paciente respondedora parcial a la piridoxina.

Abstract: This article presents the case of a 13-year-old girl with a 2-year history of headache, which has been studied for lens subluxation and Marfanoid phenotype. To carry out this research, a simple brain tomography was performed that showed thrombosis of several sinuses. Subsequently, the patient was hospitalized in the intensive care unit and anticoagulated with enoxaparin. A study was requested for thrombophilia along with homocysteine in blood, on suspicion of homocystinuria. After confirming the diagnosis, pyridoxin and folic acid were prescribed, with which the patient evolved satisfactorily and recovered lost functions. Follow-up on this case for the research allowed us to find a decrease in homocysteine greater than 20 %, without its levels being below 50 µmol/L, which makes the patient partially responsive to pyridoxine.

Resumo: Neste artigo, é apresentado o caso de uma menina de 13 anos, com história de cefaleia de dois anos de evolução, a qual tem sido estudada por subluxação do cristalino e fenótipo marfanoide. Para realizar a pesquisa, foi tomada uma tomografia cerebral simples que evidenciou trombose de vários seios cerebrais. Em seguida, a paciente foi internada na unidade de tratamento intensivo onde recebeu tratamento anticoagulante com enoxaparina. Foi solicitado um estudo para trombofilia junto com homocisteina em sangue, diante da suspeita de homocistinúria. Após o diagnóstico ter sido confirmado, foram receitados piridoxina e ácido fólico, com os quais o estado da paciente evoluiu de maneira satisfatória e ela recuperou as funções perdidas. O seguimento do caso para a pesquisa permitiu verificar uma diminuição maior de 20% da homocisteina, sem que seus niveis estivessem abaixo de 50 µmol/L, fato que torna a paciente apta parcialmente à piridoxina.

Efficacy and safety of Shenxiong Glucose Injection in treatment of cerebral thrombosis:systematic review and Meta-analysis / 中国中药杂志

To systematically evaluate the efficacy and safety of Shenxiong Glucose Injection in the treatment of cerebral thrombosis.Randomized controlled trials( RCTs) of Shenxiong Glucose Injection for cerebral thrombosis were screened out by searching CNKI,Wan Fang,VIP,Sino Med,Cochrane Library,PubMed,EMbase,and Web of Science in a systematic way,and the Meta-analysis on finally included studies was conducted by using Handbook 5. 1 evaluation criteria and tools and Rev Man 5. 3 software. GRADE system( GRADE pro 3. 6. 1) was used to grade the evidence quality of key outcome indicators. A total of 25 studies were included,with a total sample size of 2 286 cases,1 144 in the experimental group and 1 142 in the control group. The results of Meta-analysis showed that the total effective rate of Shenxiong Glucose Injection combined with ozagrel in the treatment of cerebral thrombosis was better than that of ozagrel alone( RR = 1. 26,95%CI [1. 20,1. 32],P<0. 000 01); the total effective rate of conventional treatment plus Shenxiong Glucose Injection and ozagrel for cerebral thrombosis was better than that of conventional treatment combined with ozagrel( RR = 1. 26,95%CI [1. 09,1. 46],P = 0. 002). In addition,Shenxiong Glucose Injection combined with ozagrel could reduce the incidence of adverse reactions( RR = 0. 38,95%CI [0. 24,0. 60],P < 0. 000 1),improve the neurological impairment( MD14 d=-7. 19,95% CI[-9. 16,-5. 22],P< 0. 000 1; MD30 d=-5. 34,95% CI [-5. 85,-4. 83],P < 0. 000 1; MD42 d=-7. 03,95% CI [-7. 79,-6. 28],P<0. 000 01; MD60 d=-6. 18,95%CI [-6. 55,-5. 81],P< 0. 000 01; MD90 d=-4. 90,95% CI [-5. 74,-4. 06],P<0. 000 01),and improve activities of daily living( ADL)( MD = 15. 00,95%CI [12. 20,17. 80],P<0. 000 01). The mortality was only included in one study,and the sample size was small,requiring to be further verified by a large sample size. The adverse reactions mainly included lung infection,skin pruritus,gastrointestinal reaction and so on,all of which could be tolerated or disappeared without affecting the treatment. Based on the available data and methods,Shenxiong Glucose Injection combined with ozagrel for cerebral thrombosis could improve the total effective rate,neurological impairment,and ability of daily living,with no serious adverse reactions. The evidence quality level of GRADE system was low in the evaluation of total effective rate,mortality and incidence of adverse reactions.However,the quality of the included researches was not high,requiring rigorously designed and internationally standardized clinical trials with a large sample size to improve the quality of evidence.

Massive cerebral venous sinus thrombosis secondary to Graves' disease / 영남의대학술지

Cerebral venous sinus thrombosis (CVT) is a rare cerebrovascular condition accounting for 0.5–1% of all types of strokes in the general population. Hyperthyroidism is associated with procoagulant and antifibrinolytic activity, thereby precipitating a hypercoagulable state that predisposes to CVT. We report the case of a 31-year-old Korean man with massive CVT and diagnosis of concomitant Graves' disease at admission. Early diagnosis and prompt treatment of CVT are important to improve prognosis; therefore, CVT should be considered in the differential diagnosis in all patients with hyperthyroidism presenting with neurological symptoms.

Otite externa necrotizante com paralisia facial periférica e trombose do seio cavernoso: relato de caso / Necrotizint external otitis with peripheral facial paralysis and cavernous sinus thrombosis: case report

Otite externa necrotizante (OEN), conhecida antigamente como otite externa maligna (OEM), atinge o conduto auditivo externo, causando otalgia intensa, otorreia fétida, e em casos mais severos, comprometimento dos ossos do crânio e déficit neurológico. O agente etiológico mais comum é a Pseudomonas aeruginosa. Acomete principalmente pacientes idosos, diabéticos e imunodeprimidos. O comprometimento de nervo craniano levando a paralisia facial e trombose dos seios intracranianos são de piores prognósticos. O diagnóstico depende da suspeita clínica inicialmente. Os exames complementares são imprecisos, embora essenciais no seguimento. A abordagem multidisciplinar é sempre recomendada. O objetivo do trabalho é relatar as complicações clínicas de um caso de otite externa necrotizante com paralisia facial que evoluiu para trombose do seio cavernoso, levando ao óbito.

Necrotizing external otitis (NEO), formerly known as malignant external otitis (MEO), strikes the external auditory canal, causing severe otalgia, fetid otorrhea, and in more severe cases, impairment of the skull bones and neurological deficit. The most common etiological agent is Pseudomonas aeruginosa. It mainly affects elderly, diabetic and immunodepressed patients. Cranial nerve impairment leading to facial paralysis and intracranial sinus thrombosis are of bad prognos. The diagnosis depends on the clinical suspicion. Complementary exams are imprecise, although essential in the follow-up. The multidisciplinary approach is always recommended. The objective of this paper is to report the clinical complications of a case of necrotizing external otitis with facial paralysis and cavernous sinus thrombosis, leading to death.

Trombosis de senos venosos cerebrales en Pediatría / Cerebral venous sinus thromboses in Pediatrics

Introducción: la trombosis de los senos venosos cerebrales es un trastorno infrecuente en niños y adolescentes, que en muchas ocasiones es mal diagnosticado o se demora su reconocimiento, y por lo tanto, el inicio del tratamiento. Presentación de casos: se describen las principales características clínicas de 3 pacientes; uno, de 4 años y del sexo masculino, y 2 de 17 años cumplidos y del sexo femenino, con diagnóstico comprobado de trombosis de senos venosos. Se identificaron factores de riesgo en los 3 pacientes, y presentaron signos de focalización neurológica, manifestaciones de hipertensión intracraneal y papiledema (2 de ellos vómitos y cefaleas al inicio del cuadro clínico, y uno presentó inicialmente trastorno de la conciencia). Los 3 fueron tratados con anticoagulación como terapéutica específica y evolucionaron satisfactoriamente. Conclusiones: las trombosis venosas de los senos cerebrales son una forma de presentación poco frecuente, pero grave, de ictus en la infancia. La sospecha clínica debe ser considerada ante todo paciente con factores de riesgo conocidos, con instalación aguda de manifestaciones en que se sospecha un origen vascular, con hipertensión intracraneal y/o convulsiones(AU)

Introduction: cerebral venous sinus thromboses is an infrequent disorder in children and adolescents that in many cases is misdiagnosed or the diagnosis is belated, thus the beginning of the treatment. Cases presentation: clinical characteristics of 3 patients are described: one of 4 years old and male sex, and 2 of 17 years old and female sex, with a confirmed diagnosis of venous sinuses thrombosis. Risk factors were identified in the 3 patients, and they presented signs of neurological focalization, manifestations of intracraneal hypertension and papilledema (two of them vomiting and cephalalgia at the onset of the clinical manifestations, and one of them initially presented consciousness disorders). The 3 cases were treated with anticoagulation as specific therapy, and they evolved satisfactorily. Conclusions: cerebral venous sinuses thromboses are an uncommon but severe manifestation of ictus in childhood. Clinical suspicion most be considered with patients having known risk factors, acute manifestations related to vascular origin, intracranial hypertension and/or convulsions(AU)

IgG4-Related Hypertrophic Pachymeningitis Mimicking Cerebral Venous Thrombosis

Immunoglobulin G4-related hypertrophic pachymeningitis (IgG4-RHP) is an increasingly recognized manifestation of IgG4-related disease (IgG4-RD), which is a fibroinflammatory condition that can affect virtually any organ. The three hallmark histopathological features of IgG4-RD are lymphoplasmacytic infiltration of IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. We report a case of biopsy-confirmed IgG4-RHP that was initially misdiagnosed as cerebral venous thrombosis.

Utilidad del dúplex transcraneal en la Neurología: serie de casos / Useful of transcranial duplex in neurology: case series

RESUMEN El ultrasonido es una herramienta ampliamente utilizada en Medicina, en diferentes áreas como ginecología, cirugía y neurología, tiene una gran variedad de indicaciones, tales como: el estudio del vasoespasmo en hemorragia subaracnoidea, cambios de flujo en estenosis intracraneana e incluso evaluar "in vivo" la actividad de algunas medidas terapéuticas. A continuación se presenta una serie de los casos más relevantes recogidos en el Hospital Universitario Mayor que fueron llevados a dúplex transcraneal y sus resultados. De igual manera una breve revisión sobre las patologías más frecuentes que se pueden encontrar mediante este estudio. El dúplex transcraneal ofrece entonces un medio diagnóstico de rápida evaluación que otorga información fehaciente para la toma de decisiones tanto en el servicio de urgencias como en hospitalización, pero se trata de una herramienta con la que se tiene poca experiencia en el país, por lo que estos hallazgos son pioneros y deben complementarse con estudios de mayor peso.

SUMMARY Ultrasound is a tool that is widely used in medicine in different areas such as gynecology or surgery. In neurology, it has a broad variety of indications, related to the study of vasospasm and subarachnoid haemorrhage, besides of flux changes in intracranial stenosis and it helps to evaluate the activity of some therapeutic measures. In this article we present some of the most relevant cases collected in the Hospital Universitario Mayor, wich were taken to a trans cranial duplex and we provide a short revision about most frequent pathologic that can be found through this study. The transcranial duplex offers a diagnose possibility of fast evaluation that takes reliable information to make choices in the emergency room as in the hospitalized. Although this procedure does not have many experience in the country, it is important to mention that these findings turn out to be an innovating solution to a quick diagnose that should be complemented with further information.

Cerebral venous thrombosis after spinal anesthesia: case report / Trombose venosa cerebral após raquianestesia: relato de caso

Abstract Introduction Cerebral venous thrombosis (CVT) is a rare but serious complication after spinal anesthesia. It is often related to the presence of predisposing factors, such as pregnancy, puerperium, oral contraceptive use, and malignancies. Headache is the most common symptom. We describe a case of a patient who underwent spinal anesthesia and had postoperative headache complicated with CVT. Case report Male patient, 30 years old, ASA 1, who underwent uneventful arthroscopic knee surgery under spinal anesthesia. Forty-eight hours after the procedure, the patient showed frontal, orthostatic headache that improved when positioned supine. Diagnosis of sinusitis was made in the general emergency room, and he received symptomatic medication. In subsequent days, the headache worsened with holocranial location and with little improvement in the supine position. The patient presented with left hemiplegia followed by tonic-clonic seizures. He underwent magnetic resonance venography; diagnosed with CVT. Analysis of procoagulant factors identified the presence of lupus anticoagulant antibody. The patient received anticonvulsants and anticoagulants and was discharged on the eighth day without sequelae. Discussion Any patient presenting with postural headache after spinal anesthesia, which intensifies after a plateau, loses its orthostatic characteristic or become too long, should undergo imaging tests to rule out more serious complications, such as CVT. The loss of cerebrospinal fluid leads to dilation and venous stasis that, coupled with the traction caused by the upright position, can lead to CVT in some patients with prothrombotic conditions.

Resumo Introdução: A trombose venosa cerebral (TVC) é uma complicação rara, mas grave, após raquianestesia. Está frequentemente relacionada com a presença de fatores predisponentes, como gestação, puerpério, uso de contraceptivos orais e doenças malignas. O sintoma mais frequente é a cefaleia. Descrevemos um caso de um paciente submetido à raquianestesia que apresentou cefaleia no período pós-operatório complicada com TVC. Relato de caso: Paciente de 30 anos, ASA 1, submetido à cirurgia de artroscopia de joelho sob raquianestesia, sem intercorrências. Quarenta e oito horas após o procedimento apresentou cefaleia frontal, ortostática, que melhorava com o decúbito. Foi feito diagnóstico de sinusite em pronto socorro geral e recebeu medicação sintomática. Nos dias subsequentes teve pioria da cefaleia, que passou a ter localização holocraniana e mais intensa e com pequena melhora com o decúbito dorsal. Evoluiu com hemiplegia esquerda seguida de convulsões tônico-clônicas generalizadas. Foi submetido à ressonância magnética com venografia que fez o diagnóstico de TVC. A pesquisa para fatores pró-coagulantes identificou a presença de anticorpo lúpico. Recebeu como medicamentos anticonvulsivantes e anticoagulantes e teve alta hospitalar em oito dias, sem sequelas. Discussão: Qualquer paciente que apresente cefaleia postural após uma raquianestesia, e que intensifica após um platô, perca sua característica ortostática ou se torne muito prolongada, deve ser submetido a exames de imagem para excluir complicações mais sérias como a TVC. A perda de líquido cefalorraquidiano leva à dilatação e à estase venosa, que, associadas à tração provocada pela posição ereta, podem, em alguns pacientes com estados protrombóticos, levar à TVC.

Pacientes con evento cerebrovascular isquémico con criterios de trombolisis endovenosa en el Instituto Salvadoreño del Seguro Social / Patients with ischemic cerebrovascular event with endovenous thrombolysis criteria at the "Instituto Salvadoreño del Seguro Social"

El evento cerebrovascular isquémico se define como la presencia de síntomas neurológicos focales que persisten en un periodo de tiempo mayor a 24 horas, con evidencia por imagen de una lesión isquémica cerebral aguda. Este constituye una de las principales causas de morbimortalidad a nivel mundial con altos índices de año de vida perdidos. Se ha demostrado que la asistencia y manejo de pacientes en el periodo agudo de un evento cerebro vascular isquémico en las primeras 4.5 horas puede a largo plazo, minimizar la injuria cerebral y preservar el adecuado funcionamiento cerebral y aminorar por tanto las complicaciones médicas agudas y el grado de discapacidad. Entre las estrategias terapéuticas se ha observado que la trombolisis endovenosa con activador del plasminógeno tisular (rt-PA) ha mostrado beneficio en estos pacientes, estableciendo criterios de inclusión y exclusión para la utilización de dicho tratamiento; además de la utilización de escalas de valoración clínica como la escala NIHSS (National Institutes for Health Stroke Scale) escala que permite valorar la severidad del evento y el riesgo de hemorragia al realizar terapia trombolítica y la ASPECTS (The Alberta Stroke programearly CT score), desarrollado para facilitar el reconocimiento temprano de la isquemia en la tomografía computarizada cerebral. El objetivo de este estudio fue analizar el porcentaje de pacientes con evento cerebrovascular isquémico con criterios para administración de terapia trombolítica, utilizando las escalas pronósticas de NIHSS y ASPECT. Se realizó la revisión de los expedientes delos pacientes atendidos en los servicios de medicina interna de los Hospitales Médico Quirúrgico y Hospital General ISSS, tomando una muestra no probabilística de casos consecutivos de 80 pacientes con un intervalo de confianza del 95%. Encontrando los siguientes resultados en cuanto al cumplimiento de criterios de inclusión para realizar trombolisis el 92.5% de pacientes no cumplió criterios, sólo un 7.5% los cumplía. En la aplicación de escalas de valoración clínica (NIHSS) para cumplimiento de trombolisis se evidenció que el 85% de pacientes tuvo una escala clínica entre 0 a 20 puntos, es decir un buen pronóstico para trombolisis; un 11.3% entre 21 a 25 puntos, con pronóstico reservado para trombolisis; un 2.5% una escala mayor a 25 puntos, con mal pronóstico para trombolisis. En cuanto a la escala de imagen (TAC cerebral) ASPECT el 60% de pacientes tuvo una escala mayor a 7 puntos lo que favorece un buen pronóstico al realizar trombolisis y un 15% de pacientes una escala entre 0 y 7 puntos, mal pronóstico para trombolisis

Diagnostic and Therapeutic Strategies for Acute Intracranial Atherosclerosis-related Occlusions / 대한뇌졸중학회지

Intracranial atherosclerosis-related occlusion (ICAS-O) is frequently encountered at the time of endovascular revascularization treatment (ERT), especially in Asian countries. However, because baseline angiographic findings are similar between ICAS-O and embolism-related occlusion (EMB-O), it is difficult to differentiate the etiologies before the ERT procedure. Moreover, despite successful randomized trials on ERT, results from studies examining the optimal treatment protocol in ICAS-O patients remain unclear. In this review, we describe the clinical and imaging factors that may possibly differentiate ICAS-O from EMB-O. We will also discuss some current hurdles for treating ICAS-O in the hyperacute period and suggest the optimal ERT strategy for ICAS-O patients.

Clinical Characteristics of Patients with Diabetic Nephropathy on Maintenance Hemodialysis: A Multicenter Cross-sectional Survey in Anhui Province, Eastern China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The incidence of diabetic nephropathy (DN) increases year by year. However, clinical characteristics of DN patients on maintenance hemodialysis (MHD) were rarely reported in China. The purpose of this study was to examine the clinical characteristics of the DN patients on MHD in Anhui Province, Eastern China.</p><p><b>METHODS</b>The clinical data of MHD patients in the hemodialysis centers of 26 hospitals in Anhui Province from January 1, 2014, to March 31, 2014, were examined. The differences between DN patients and non-DN patients were compared regarding vascular access, nutritional status, mineral and bone disorder, and other indexes.</p><p><b>RESULTS</b>Among the selected 2768 adult MHD patients, 427 had DN. The incidence of hypertension, coronary heart disease, and cerebral thrombus in DN patients was 94.1%, 21.5%, and 15.0%, respectively, which were higher than those in non-DN patients (P < 0.001). Category of vascular access for hemodialysis in DN patients was arteriovenous fistula (AVF) (87.4% [373/427]) and tunneled cuffed catheter (TCC) (11.2% [48/427]). The percentage of AVF was significantly lower than that of non-DN patients (P < 0.001), and percentage of TCC was significantly higher than that of non-DN patients (P < 0.001). Hemoglobin achievement rate in DN patients was 32.0%. The incidence of hypoalbuminemia was 24.7%, significantly higher than that in non-DN patients (P < 0.001). The achievement rate of the target range in mineral values was 55.9% in corrected serum calcium level, 30.1% in serum phosphorus level, and 49.3% in intact parathyroid hormone (iPTH) level in DN patients. Compared with non-DN patients, the achievement rate of serum phosphorus was significantly higher in DN patients.</p><p><b>CONCLUSIONS</b>DN patients on MHD in Anhui province exhibited different clinical characteristics compared to non-DN hemodialysis patients. They presented higher percentage in TCC use and cardiovascular complication, lower serum albumin and iPTH levels than those in non-DN patients.</p>

A new method for evaluating regional cerebral blood flow changes: Laser speckle contrast imaging in a C57BL/6J mouse model of photothrombotic ischemia / 华中科技大学学报（医学）（英德文版）

The present study aimed to improve the processing of data acquired from laser speckle contrast imaging (LSCI) to provide a standardization method to explore changes in regional cerebral blood flow (rCBF) and to determine the correlations among rCBF, cerebral ischemic lesion volume and microvascular density over time in a focal ischemic region. C57BL/6J mice were subjected to focal photothrombotic (PT) ischemia. rCBF was measured using LSCI at different time points before and after PT ischemia through an intact skull. Standardized rCBF (SrCBF), defined as the ratio of rCBF measured in the ipsilateral region of interest (ROI) to that in the corresponding contralateral region, was calculated to evaluate potential changes. In addition, the volume of the ischemic lesion and the microvascular density were determined using Nissl staining and immunofluorescence, respectively. The relationships among the ischemic lesion volume, microvascular density and SrCBF were analyzed over time. The results showed that the cortical rCBF measured using LSCI following PT ischemia in the C57BL/6J mice gradually increased. Changes in the cerebral ischemic lesion volume were negatively correlated with SrCBF in the ischemic region. Changes in the microvascular density were similar to those observed in SrCBF. Our findings indicate that LSCI is a practical technique for observing changes in murine cortical rCBF without skull opening and for analyzing the relationships among the ischemic lesion volume, microvascular density and SrCBF following focal cerebral ischemia. Preliminary results also suggest that the use of LSCI to observe the formation of collateral circulation is feasible.
