Estado actual de la cefalea postpunción meníngea en un hospital colombiano / Status of post-dural puncture headache in a Colombian hospital

Introducción: La cefalea postpunción meníngea (CPPM) posterior a la anestesia raquídea es una de las complicaciones más frecuentes asociadas a factores intrínsecos del paciente y de la técnica anestésica. Objetivo: Describir la frecuencia y los factores asociados con el desarrollo de la cefalea postpunción meníngea. Materiales y métodos: Serie retrospectiva de pacientes que ingresaron a un hospital de segundo nivel y se les confirmó el diagnóstico de cefalea secundaria a la anestesia raquídea. Resultados: Serie de 49 casos, 88 % de sexo femenino y 12 % de sexo masculino, con una edad media de 27,7 años. Los procedimientos quirúrgicos con desenlace de CPPM fueron: cirugías de ginecología y obstetricia (63 %), cirugías de urgencias de otras especialidades (28 %) y cirugías electivas (8 %). La técnica anestésica se realizó con agujas biseladas tipo Quincke calibre 25 gauge (G) en 14%, calibre 26 G 33 % y 27 G 53 %. El 51 % se realizó en posición de sedestación y el 49 % en decúbito lateral izquierdo. El 10% de los casos se manejó con parche hemático, en tanto que el antecedente de migraña se presentó en el 8 %. Discusión: En la actualidad, el uso de agujas con diseño de punta cónica es el estándar de oro, ya que permite obtener resultados confiables y disminuye complicaciones como la CPPM. Conclusión: La CPPM luego de una anestesia espinal se relacionó con factores como la edad (joven), el sexo (femenino) y el uso de agujas biseladas. Los otros factores de riesgo identificados fueron poco concluyentes, aunque no se pueden descartar, debido a la naturaleza de este estudio.

Introduction: Post dural puncture headache (PDPH) following spinal anesthesia is one of the most frequent complications associated with intrinsic patient and anesthetic technique factors. Objective: To describe the frequency and associated factors related to the development of PDPH. Materials and methods: Retrospective series of patients admitted to a second level hospital with a confirmed diagnosis of headache secondary to spinal anesthesia. Results: Series of 49 cases, 88 % female and 12 % male, mean age 27.7 years. The surgical procedures resulting in CPPM were gynecology and obstetrics surgeries 63 %, emergency surgeries of other specialties 28 % and elective surgeries 8 %. The anesthetic technique was performed with beveled needles Quincke type 25 gauge (G) in 14 %, 26 G gauge 33% and 27 G 53 %. In the seated position 51 % and in the left lateral decubitus position 49% were performed. A blood patch was used in 10 % of the cases and a history of migraine was present in 8 %. Discussion: The use of needles with conical tip design is currently the gold standard, they give reliable results and reduce complications such as PDPH. Conclusion: PDPH after spinal anesthesia was related to factors such as age (young), sex (female) and the use of traumatic needles. The other risk factors identified were inconclusive, although they cannot be ruled out due to the nature of this study.

Ruptura prematura de membranas ovulares / Premature rupture of ovular membranes

La ruptura prematura de las membranas ovulares se define como la pérdida de la integridad del amnios y corion antes del inicio del trabajo de parto, afecta el 3 % de los embarazos, causa un tercio de los partos pretérminos, los cuales ocupan el 10,49 % de los nacimientos y es el origen de altos índices de morbimortalidad perinatal. En la actualidad, el manejo de esta patología se orienta principalmente en evitar los factores de riesgo, hacer un diagnóstico adecuado, determinar la edad gestacional en que ocurre, realizar el monitoreo exhaustivo del bienestar materno-fetal y en decidir el momento idóneo de finalización de la gestación para minimizar sus complicaciones. Debido a la compleja y lábil estructura histológica de las membranas ovulares, se ha dejado a un lado el tratamiento directo de la entidad el cual sería sellar o reparar el defecto en sí. En los últimos años, numerosos estudios y protocolos clínicos de prestigiosos centros asistenciales han servido como guía para el manejo de esta entidad, pero en muy pocos se observa una terapia destinada a la reparación de dichas membranas o en sellar tal defecto. Las evidencias científicas demuestran que la regeneración y reparación de las membranas es lenta y compleja y los tratamientos propuestos para reparar o sellar su defecto no han gozado de la aceptación científica para su aprobación, sin embargo, el uso del parche hemático transvaginal endocervical autólogo luce como una alternativa terapéutica prometedora(AU)

The premature rupture of the ovular membranes is defined as the loss of the integrity of the amnion and chorion before the on set of labor, affects 3% of pregnancies, causes athird of preterm births which occupy 10,49% of births and is the origin of high rates of perinatal morbidity and mortality. At present, the management of this pathology is mainly oriented towards avoiding risk factors, making an adequate diagnosis, determining the gestational age in which it occurs, carrying out exhaustive monitoring of maternal-fetal well-being and deciding the ideal moment to end the treatment. Pregnancy to minimizeits complications. Due to the complex and labile histological structure of the ovular membranes, the direct treatment of the entity has been set a side, which would be to seal or repairthe defect it self. In recent years, numerous studies and clinicalprotocols from prestigious health care centers have served as aguide for the management of this entity, but very few have observed a therapy aimed at repairing said membranes or sealing such a defect. Scientific evidence shows that the regeneration and repair of the membranes is slow and complex and the treatment sproposed to repair or seal their defect have not enjoyed scientific acceptance for their approval, how ever, the use of the autologous endocervical transvaginal blood patch looks like a promising therapeutic alternative(AU)

It's not always postdural puncture headache: a case report and note to the astute anesthesiologist

Abstract Dural puncture is either diagnosed by unexpectedly profound response to medication test dose or development of a postpartum postural headache. Epidural blood patch is the gold standard for treatment of PDPH when conservative management fails. However, postpartum headaches can be resistant to multiple epidural blood patches. In such cases, preexisting intracranial processes should be considered and ruled out. We report here the unique case of a pregnant patient who developed a resistant headache in the postpartum period related to an incidental intracranial aneurysm. Subsequent treatment with endovascular embolization adequately relieved her symptoms. Early surgical consultation and a multidisciplinary team approach involving neurology and neuroimaging is required for successful management of patients such as the one described here.

Spontaneous intracranial hypotension: analysis of 118 patients ' clinical characteristics / 中华神经科杂志

Objective:To summarize the clinical features, radiological characteristics, therapy, and outcome of patients with spontaneous intracranial hypotension (SIH).Methods:The general information, clinical manifestations, auxiliary examinations, treatment, and outcomes in consecutive patients of SIH hospitalized in the Xuanwu Hospital, Capital Medical University from November 2018 to October 2022 were analyzed.Results:A total of 118 patients with a female-to-male ratio of 5∶4 were included and the ages were 17.00-71.00[39.00(34.00,46.75)]years with a preponderance in the age of 30-49 years. Almost all patients had orthostatic headaches (117/118, 99.2%), accompanied by nausea (90/118, 76.3%), vomiting (70/118, 59.3%), neck stiffness (88/118, 74.6%), tinnitus (57/118, 48.3%), and ear fullness (57/118, 48.3%). Brain magnetic resonance imaging (MRI) showed dural enhancement (97/113, 85.8%), enlarged venous sinus (88/113, 77.9%), subdural fluid collection (46/113, 40.7%), decreased suprasellar cistern (86/113, 76.1%), effacement of the prepontine cistern (86/113, 76.1%), diminished mamillopontine distance (80/113, 70.8%). The cerebrospinal fluid (CSF) leaks were detected in 90.7% (107/118) of the patients by magnetic resonance myelography but 54.3% (25/46) and 52.6% (20/38) by CT myelography and magnetic resonance myelography with gadolinium. Lumber puncture found CSF pressure<60 mmH 2O (1 mmH 2O=0.009 8 kPa) in 18.4% (19/103) of patients, increased CSF red blood cell counts in 50.6% (44/87) of patients, CSF pleocytosis in 44.8% (39/87) of patients, increased CSF protein concentrations in 57.5% (50/87) of patients. The headache completely disappeared after conservative treatment in 24.6% (31/118) of patients and after a single targeted epidural blood patch in 89.7% (78/87) of patients. A rebound headache after epidural blood patch treatment occurred in 66.0% (58/87) of patients. Conclusions:The patients with SIH almost manifested with orthostatic headache, and brain MRI and magnetic resonance myelography were suggested in those patients instead of CSF pressure by lumber puncture. Targeted epidural blood patch was effective and safe in SIH patients.

Spontaneous intracranial hypotension caused by high-flow spinal cerebrospinal fluid leaks: analysis of 6 patients / 中华神经科杂志

Objective:To analyze the clinical features of 6 patients with spontaneous intracranial hypotension caused by high-flow spinal cerebrospinal fluid leaks.Methods:The clinical characteristics, auxiliary examinations, treatment, and outcomes in 6 patients of spontaneous intracranial hypotension caused by high-flow spinal cerebrospinal fluid leaks enrolled in the Xuanwu Hospital, Capital Medical University from February 2021 to April 2022 were retrospectively reviewed.Results:All the 6 patients had orthostatic headaches. Brain magnetic resonance imaging showed dural enhancement and brain sagging and magnetic resonance myelography showed longitudinal extradural collection in all the patients. The high-flow spinal cerebrospinal fluid leaks were demonstrated in upper thoracic segments by the dynamic myelography. The headache disappeared after conservative treatment in 2 patients and treatment with targeted epidural blood patch in 4 patients.Conclusions:The diagnosis of spontaneous intracranial hypotension caused by high-flow spinal cerebrospinal fluid leaks with typical orthostatic headache and brain magnetic resonance imaging and myelography findings is not difficult. However, the localization of the site of high-flow spinal cerebrospinal fluid leaks in spontaneous intracranial hypotension depends on the dynamic myelography. Targeted epidural blood patch is effective, but conservative treatment does not always work.

Analysis of the clinical characteristics of 8 cases of spontaneous intracranial hypotension / 中华全科医师杂志

Objective:To analyze the clinical characteristics of patients with spontaneous low intracranial pressure (SIH).Methods:The study is a retrospective series. The clinical data of patients with SIH who visited Beijing Hospital from May 2017 to March 2022, including gender, age, symptoms, signs, imaging findings, treatment and outcome, were collected and their clinical characteristics were analyzed.Results:Finally, 8 patients with SIH, 6 females and 2 males, aged (33.5±7.3) years, were included. There were 6 cases of acute onset, 1 case of subacute onset, and 1 case of chronic onset. Four cases had pre-onset triggers, 3 cases were exertional and 1 case was exercise. All 8 cases had orthostatic headache. Three cases were accompanied by neck pain. Six cases were accompanied by autonomic dysfunction, 1 case with blurred vision and neck resistance, and 1 case with tinnitus in both ears. There were no obvious abnormalities in blood routine, liver and kidney function, electrolytes, and coagulation function in 8 cases. The results of the lumbar puncture showed that the cerebrospinal fluid pressure was≤60 mmH 2O(1 mmH 2O=0.009 8 kPa) in 7 cases, and 2 cases were so low that they were undetectable. One patient had normal cerebrospinal fluid pressure (90 mmH 2O). The routine results of cerebrospinal fluid showed 4 cases of an increased number of red blood cells and 2 cases of leukocytosis. The biochemical results of cerebrospinal fluid in all 8 cases were normal. All 8 patients underwent non-contrast MRI scan of the head, and 6 cases found abnormalities, including 2 cases of subdural hematoma, 1 case of subarachnoid hemorrhage, 1 case of brain tissue sinking, and 3 cases of intracranial venous sinus dilation (including 1 case with subdural hematoma). All 8 patients underwent MRI enhancement scan of the head, and 5 patients showed diffuse dural enhancement. Three patients underwent digital subtraction angiography myelogram and computed tomography myelogram, and 2 cases found dural cerebrospinal fluid leakage. One patient underwent magnetic resonance water imaging and no cerebrospinal fluid leakage was found. Eight patients were followed up for 38.5 (10.3, 63.0) months, after conservative treatment, 6 cases of headache relief or disappearance, 1 case relapsed and was admitted 1 week after discharge, non-targeted epidural blood patching (EBP) did not relapse, 1 case underwent non-targeted EBP after conservative treatment failure, headache relief, recurrence after 2 months, thoracic spine 3-4 space targeted EBP, headache disappeared, did not recur. Conclusions:The present study indicate that SIH prevalence in young age is common, the main symptom is orthostatic headache, accommodated with multiple clinical symptoms with various imaging abnormalities. Most patients with SIH can be treated conservatively, if the effect is not good, non-targeted or targeted EBP is feasible.

Síndrome De Hipotensión Endocraneana Espontánea: Reporte De Un Caso Clínico / Spontaneous Intracranial Hypotension Syndrome: Clinic Case Report

La hipotensión intracraneal espontánea (SIH) es una patología con una incidencia anual aproximada de 5 por cada 100.000 personas al año, caracterizada clásicamente por cefalea ortostática comúnmente secundaria a una fuga espontánea de líquido cefalorraquídeo (LCR), pudiendo existir a su vez una amplia gama de síntomas asociados. El diagnóstico se centra en la clínica y en hallazgos típicos en la resonancia nuclear magnética (RM), sin embargo, según diversos estudios, puede corresponder a una patología subdiagnosticada por la dificultad que ha existido en definir criterios diagnósticos universales y un manejo terapéutico estandarizado, el cual varía inicialmente entre manejo médico conservador y/o parches de sangre epidural (PHE). Reportamos el caso de una paciente femenina de 51 años quien fue atendida en el Hospital Herminda Martin de Chillán donde se realizó el diagnóstico y tratamiento sintomático con PHE.

Spontaneous intracranial hypotension (SIH) is a pathology with an annual incidence of approximately 5 per 100,000 people per year, classically characterized by orthostatic headache commonly secondary to a spontaneous cerebrospinal fluid (CSF) leak, and there may also be a wide range of of associated symptoms. The diagnosis is centered on the clinic and on typical findings in magnetic resonance imaging (MRI), however, according to various studies, it may correspond to an underdiagnosed pathology due to the difficulty that has existed in defining universal diagnostic criteria and standardized therapeutic management. which initially varies between conservative medical management and/or epidural blood patches (PHE). We report the case of a 51-year-old female patient who was treated at the Herminda Martin de Chillán Hospital where the diagnosis and symptomatic treatment with PHE were made.

Parche de sangre cervical para tratamiento de síndrome de hipotensión/ hipovolumen de líquido cefalorraquídeo espontáneo. Reporte de un caso / Cervical blood patch for the treatment of spontaneous cerebrospinal fluid hypotension/hypovolume syndrome. A case report

Presentamos el tratamiento eficaz de una filtración espontánea de líquido cefalorraquídeo (LCR) asociada a un síndrome de hipoten-sión/hipovolumen de LCR a nivel cervical alto, caracterizado por delirio y hematomas subdurales secundarios, refractarios al drenaje quirúrgico, que se resolvió con dos parches de sangre epidurales cervicales consecutivos.

We present the case of a cerebrospinal fluid (CSF) hypotension/hypovolume syndrome due to a spontaneous CSF fistula at the upper cervical level characterized by loss of consciousness and bilateral subdural hematomas refractory to two drainage surgeries that resolved with two consecutive blood patches on the leak site.

Coma in spontaneous intracranial hypotension complicated with subdural hematoma: a case report / 中华神经科杂志

Spontaneous intracranial hypotension can frequently result in several complications including subdural hygroma, subdural hematoma and cerebral venous thrombosis, but coma rarely. A case of spontaneous intracranial hypotension presented with orthostatic headaches was described. He experienced somnolence, disorientation, incontinence, and then coma, though received conservative treatment. Brain imaging demonstrated acute-on-chronic subdural hematoma, magnetic resonance myelography using heavily T 2-weighted fast spin-echo pulse sequences showed spinal longitudinal extradural collection, and magnetic resonance myelography with intrathecal gadolinium revealed cerebrospinal fluid leak at the level of T 6, T 7. The patient recovered consciousness after surgical evacuation of the hematoma, and the headache disappeared after a targeted epidural blood patch. The hematoma resolved 2 months later and the patient kept free from headache during follow-up.

New approaches and therapeutic options for post-dural puncture headache treatment / Nuevos abordajes y alternativas terapéuticas en el tratamiento de la cefalea pospunción dural

Abstract Post-dural puncture headache is a frequent complication in neuraxial approaches. It may result in disability, healthcare dissatisfaction and potentially serious complications. The traditional initial management includes general and analgesia measures with poor evidence. The treatment approach best supported by the literature is the epidural blood patch for which rates of up 70% improvement have been reported. Regional techniques have been recently described that may be helpful because they are less invasive than the epidural blood patch, under certain clinical circumstances. This article suggests an algorithm that uses such techniques for the management of this complication.

Resumen La cefalea pospunción dural es una complicación frecuente del abordaje del neuroeje. Puede producir incapacidad, insatisfacción con la atención en salud y complicaciones potencialmente graves. Tradicionalmente su manejo inicial incluye medidas generales y de analgesia las cuales tienen baja evidencia. La medida para su tratamiento, con mejor soporte en la literatura, es la realización de parche hemático, el cual informa tazas de mejoría hasta del 70 %. Recientemente se han descrito técnicas regionales, que pueden resultar útiles por ser menos invasivas que el parche hemático, en ciertos contextos clínicos. En este artículo se propone un algoritmo que permite incorporar dichas técnicas al manejo de esta complicación.

Predictors of the Response to an Epidural Blood Patch in Patients with Spinal Leakage of Cerebrospinal Fluid

Multiple epidural fibrin glue patches in a patient with spontaneous intracranial hypotension:A case report

BACKGROUND: Spontaneous intracranial hypotension (SIH) is a condition caused by spontaneous leakage of cerebrospinal fluid, with postural headache as the primary symptom. Orthostatic headache caused by SIH is often not resolved by conservative management. CASE: We performed 15 epidural blood patch treatments in a 43-year-old female patient; however, they were only transiently effective. To improve the patient's SIH and orthostatic headache, epidural fibrin glue patch treatment was attempted. Fibrin glue is a substance that can act as a bio-friendly adhesive by facilitating the coagulation cascade. In our case, 3 epidural fibrin glue patch treatments were performed and the symptoms completely resolved. CONCLUSIONS: The epidural fibrin glue patch may be beneficial for the treatment of refractory postural headaches caused by SIH.

Spontaneous Intracranial Hypotension Complicated by Cerebral Venous Thrombosis Relieved by Epidural Blood Patch

Spontaneous intracranial hypotension (SIH) is characterized by orthostatic headache, diffuse dural thickening, and enhancement in magnetic resonance imaging. Cerebral venous thrombosis (CVT) has been reported to be a rare complication of SIH. There is no consensus in anticoagulation treatment of CVT secondarily caused by SIH. We report a female patient with SIH complicated by CVT and spontaneously regressed CVT not by anticoagulation but by epidural blood patch.

Parche de sangre epidural torácico, de alto volumen, para el tratamiento del Síndrome de Hipotensión Intracraneana Espontánea secundario a fuga cervical de líquido cefalorraquídeo, ¿mejora el período asintomático?. Reporte de caso / High blood volume thoracic epidural patch for the treatment of spontaneous intracranial hypotension syndrome due to cervical cerebrospinal fluid leak, It prolongs the asymptomatic period?. A case report

Mujer de 50 años, con historia de 3 semanas de cefalea ortostática progresiva y síntomas neurológicos inespecíficos, confirmándose higroma subdural a nivel C5 con fuga de líquido cefalorraquídeo compatible con Síndrome de Hipotensión Intracraneal Espontánea (SHIE). Tratamiento médico inicial sin respuesta. Se realiza parche sanguíneo epidural (PSE) a nivel torácico con 20 ml de sangre directo a través de trocar epidural, observándose respuesta terapéutica completa en seguimiento hasta 8 meses. Creemos que un PSE torácico ofrece las ventajas de uno cervical y lumbar y, por lo tanto, debe considerarse una alternativa terapéutica eficaz en este síndrome especialmente en pacientes anatómicamente complejos.

A 50-year-old woman, with a history of three-week orthostatic headache and nonspecific neurological symptoms, has a subdural hygroma at C5 level with a cerebrospinal fluid leakage compatible with Spontaneous Intracranial Hypotension Syndrome (SIHS). Initial conservative treatment has no response. A thoracic epidural blood patch (EBP) is performed, with a 20ml blood volume spread through an epidural needle, with a complete therapeutic response up-to 8 months. We believe that a higher blood volume patch through a thoracic approach gives the advantages of cervical and lumbar EBP, and, therefore, should be considered as a therapeutic alternative especially in technical anatomically difficult patients.

Efficacy of bilateral greater occipital nerve block in postdural puncture headache: a narrative review

The Epidural blood patch is considered the gold standard for managing postdural puncture headache when supportive measures fail. However, it is a procedure which can lead to another inadvertent dural puncture. Other potential adverse events that could occur during a blood patch are meningitis, neurological deficits, and unconsciousness. The bilateral greater occipital nerve block has been used for treating chronic headaches in patients with PDPH with a single injection. This minimally invasive, simple procedure can be considered for patients early, along with other supportive treatment, and an epidural blood patch can be avoided.

Iatrogenic Development of Cerebrospinal Fluid Leakage in Diagnosing Spontaneous Intracranial Hypotension / 가정의학회지

A 34-year-old woman came to the emergency room complaining of a severe orthostatic headache. Results of a cerebrospinal fluid tap and brain computed tomography were normal. Based on her history and symptoms, she was found to have spontaneous intracranial hypotension. She was hospitalized and her symptoms improved with conservative treatment. On the next day, her headache suddenly worsened. Cisternography was performed to confirm the diagnosis and determine the spinal level of her cerebrospinal fluid leak. It revealed multiple cerebrospinal fluid leaks in the lumbar and upper thoracic regions. It was strongly believed that she had an iatrogenic cerebrospinal fluid leak in the lumbar region. An epidural blood patch was performed level by level on the lumbar and upper thoracic regions. Her symptoms resolved after the epidural blood patch and she was later discharged without any complications. In this case, an iatrogenic cerebrospinal fluid leak was caused by a dural puncture made while diagnosing spontaneous intracranial hypotension, which is always a risk and hampers the patient's progress. Therefore, in cases of spontaneous intracranial hypotension, an effort to minimize dural punctures is needed and a non-invasive test such as magnetic resonance imaging should be considered first.

Epidural blood patch treatment of diplopia that developed after headache resolution in a patient with spontaneous intracranial hypotension

Sudden headache onset may rarely be caused by spontaneous intracranial hypotension (SIH). Other associated symptoms in patients with SIH are nausea, vomiting, vertigo, hearing alteration, and visual disturbance. This case report describes a 43-year-old female diagnosed with SIH who developed diplopia after resolution of an abrupt-onset headache, which was managed with conservative treatments, including bed rest and hydration. She was also diagnosed with secondary right sixth cranial nerve palsy. Although conservative management relieved her headache, the diplopia was not fully relieved. Application of an autologous epidural blood patch successfully relieved her diplopia, even after 14 days from the onset of visual impairment.
