The modified Valsalva maneuver in hypopharynx CT scan / 临床耳鼻咽喉头颈外科杂志

Objective:To analyze the significance and factors influencing of CT scan under the modified Valsalva maneuver. Methods:Clinical data of 52 patients with hypopharyngeal carcinoma diagnosed from August 2021 to December 2022 were collected, all patients had calm breathing CT scan and modified Valsalva maneuver CT scan. Compare the exposure effect of the aryepiglottic fold, interarytenoid fold, postcricoid area, piriform fossa apex, posterior hypopharyngeal wall, and glottis with each CT scanning method. The effects of age, neck circumference, neck length, BMI, tumor site, and T stage on the exposure effect were analyzed. Results:In 52 patients, 50 patients（96.15%） completed CT scan at once time. The exposure effect of the CT scan under modified Valsalva maneuver in the aryepiglottic fold, interarytenoid fold, postcricoid area, piriform fossa apex, posterior hypopharyngeal wall was significantly better than CT scan under calm breathing（Z=-4.002, -8.026, -8.349, -7.781, -8.608, all P<0.01）, while CT scan under modified Valsalva maneuver was significantly worse in glottis than CT scan under calm breathing（Z=-3.625, P<0.01）. In the modified Valsalva CT scan, age had no obvious effect on the exposure effect. The exposure effect was better with long neck length, smaller neck circumference, smaller BMI and smaller T stage. The exposure of postcricoid carcinoma was better than pyriform sinus carcinoma and posterior hypopharyngeal wall carcinoma. But differences were not all statistically significant. Conclusion:The anatomical structure of the hypopharynx was clearly under CT scan with modified Valsalva maneuver, which clinical application is simple, but the effect of glottis was worse. The influence of age, neck circumference, neck length, BMI, and tumor T stage on the exposure effect still needs further investigation.

Humanistic Care in Clinical Diagnosis and Treatment of Elderly Benign Paroxysmal Positional Vertigo Patients / 中国医学伦理学

Benign paroxysmal positional vertigo (BPPV) is a peripheral vestibular disease with the highest incidence rate, and the elderly are the high incidence population. Particle repositioning maneuver, simple and practicable, and has good clinical effects, is recognized as the preferred treatment method for BPPV. However, the elderly patients have a higher prevalence rate, often suffer from multiple chronic diseases, and their various bodily functions have entered a declining stage, with poor response to treatment and a tendency to recur. Based on these, medical staff should continuously improve their professional abilities, and pay attention to and implement some comprehensive and multi-dimensional humanistic care measures from physiological to psychological aspects such as verbal encouragement, behavioral support, and spiritual integration during the diagnosis and treatment process, to improve the quality of life of elderly BPPV patients, reduce medical disputes, and save medical resources.

Complex benign horizontal canal positional vertigo: new perceptual management

Abstract Objective: Horizontal semicircular canal site pathology of benign paroxysmal positional vertigo demonstrating three types of nystagmi on positional test were studied. We have attempted to design a protocol for its diagnosis and treatment. Methods: 320 patients of HSC-BPPV were subjected to two types of positional tests. Of these, patients with bilateral steady apogeotropic nysatgmus were treated with VAV modification of Semont's maneuver. Patients with unsteady or changing apo/geotropic signs were converted into steady geotropic ones by repetitive positional tests; followed by barbecue maneuver with forced prolong positioning. Results: Overall 88% of patients had a total recovery. 92% of patients with geotropic nystagmus showed no symptoms after second maneuveral sitting. 85% of patients with apogeotropic nystagmus recovered fully after third maneuveral sitting. Conclusion: Correct identification of subtypes of HSC-BPPV is based on provoked nystagmus by positional tests. After locating the site and side on the basis of nystagmic pattern, physician can apply the appropriate PRM. Level of evidence: II a.

A novel maneuver for diagnosis and treatment of torsional-vertical down beating positioning nystagmus: anterior canal and apogeotropic posterior canal BPPV / Uma nova manobra para diagnóstico e tratamento de nistagmo vertical para baixo com componente de torção: forma apogeotrópica da VPPB do canal anterior e canal posterior

Abstract Introduction In patients with benign paroxysmal positional vertigo, BPPV; a torsional-vertical down beating positioning nystagmus can be elicited in the supine straight head-hanging position test or in the Dix-Hallpike test to either side. This type of nystagmus can be explained by either an anterior canal BPPV or by an apogeotropic variant of the contralateral posterior canal BPPV Until now all the therapeutic maneuvers that have been proposed address only one possibility, and without first performing a clear differential diagnosis between them. Objective To propose a new maneuver for torsional-vertical down beating positioning nystagmus with a clear lateralization that takes into account both possible diagnoses (anterior canal-BPPV and posterior canal-BPPV). Methods A prospective cohort study was conducted on 157 consecutive patients with BPPV. The new maneuver was performed only in those with torsional-vertical down beating positioning nystagmus with clear lateralization. Results Twenty patients (12.7%) were diagnosed with a torsional-vertical down beating positioning nystagmus. The maneuver was performed in 10 (6.35%) patients, in whom the affected side was clearly determined. Seven (4.45%) patients were diagnosed with an anterior canal-BPPV and successfully treated. Two (1.25%) patients were diagnosed with a posterior canal-BPPV and successfully treated with an Epley maneuver after its conversion into a geotropic posterior BPPV. Conclusion This new maneuver was found to be effective in resolving all the cases of torsional-vertical down beating positioning nystagmus-BPPV caused by an anterior canal-BPPV, and in shifting in a controlled way the posterior canal-BPPV cases of the contralateral side into a geotropic-posterior-BPPV successfully treated during the followup visit. Moreover, this new maneuver helped in the differential diagnosis between anterior canal-BPPV and a contralateral posterior canal-BPPV.

Esse tipo de nistagmo pode ser explicado por uma VPPB do canal anterior ou por uma variante apogeotrópica da VPPB do canal posterior contralateral. Até agora, todas as manobras terapêuticas propostas abordam apenas uma possibilidade, sem antes fazer um diagnóstico diferencial claro entre elas. Objetivo Propor uma nova manobra para nistagmo vertical para baixo com componente de torção com uma lateralização clara que leve em consideração os dois diagnósticos possíveis, VPPB do canal anterior e VPPB do canal posterior. Método Um estudo de coorte prospectivo foi conduzido em 157 pacientes consecutivos com VPPB. A nova manobra foi feita apenas nos pacientes com nistagmo vertical para baixo com componente de torção, com lateralização nítida. Resultados Vinte pacientes (12,7%) foram diagnosticados com nistagmo vertical para baixo com componente de torção. A manobra foi feita em 10 (6,35%) pacientes, nos quais o lado afetado foi claramente determinado. Sete (4,45%) pacientes foram diagnosticados com VPPB do canal anterior e tratados com sucesso. Dois (1,25%) pacientes foram diagnosticados com VPPB do canal posterior e tratados com sucesso com a manobra de Epley após sua conversão para VPPB geotrópica de canal posterior. Conclusão Essa nova manobra mostrou-se eficaz na resolução de todos os casos de VPPB com nistagmo vertical para baixo com componente de torção causada por VPPB do canal anterior. E na mudança de forma controlada dos casos de VPPB do canal posterior do lado contralateral para uma VPPB geotrópica de canal posterior tratada com sucesso durante a consulta de seguimento. Além disso, essa nova manobra auxiliou no diagnóstico diferencial entre a VPPB do canal anterior e a VPPB do canal posterior contralateral.

Betahistine add-on therapy for treatment of subjects with posterior benign paroxysmal positional vertigo: a randomized controlled trial / Terapia adjuvante de betaistina para o tratamento de indivíduos com vertigem posicional paroxística benigna posterior: um ensaio clínico randomizado

Abstract Introduction Benign paroxysmal positional vertigo is a common vestibular disorder that accounts for one fifth of hospital admissions due to vertigo, although it is commonly undiagnosed. Objective To evaluate the effects of betahistine add-on therapy in the treatment of subjects with posterior benign paroxysmal positional vertigo. Methods This randomized controlled study was conducted in a population of 100 subjects with posterior benign paroxysmal positional vertigo. Subjects were divided into the Epley maneuver + betahistine group (group A) and Epley maneuver only (group B) group. Subjects were evaluated before and 1-week after the maneuver using a visual analog scale and dizziness handicap inventory Results One hundred subjects completed the study protocol. The Epley maneuver had an overall success rate of 95% (96% in group A; 94% in group B, p= 0.024). Groups A and B had similar baseline visual analog scale scores (6.98 ± 2.133 and 6.27 ± 2.148, respectively, p= 0.100). After treatment, the visual analog scale score was significantly lower in both groups, and was significantly lower in group A than group B (0.74 ± 0.853 vs. 1.92 ± 1.288, respectively, p= 0.000). The change in visual analog scale score after treatment compared to baseline was also significantly greater in group A than group B (6.24 ± 2.01 vs. 4.34 ± 2.32, respectively, p= 0.000). The baseline dizziness handicap inventory values were also similar in groups A and B (55.60 ± 22.732 vs. 45.59 ± 17.049, respectively, p= 0.028). After treatment, they were significantly lower in both groups. The change in score after treatment compared to baseline was also significantly greater in group A than group B (52.44 ± 21.42 vs. 35.71 ± 13.51, respectively, p= 0.000). Conclusion The Epley maneuver is effective for treatment of benign paroxysmal positional vertigo. Betahistine add-on treatment in posterior benign paroxysmal positional vertigo resulted in improvements in both visual analog scale score and dizziness handicap inventory.

Application value of inferior vena cava compression combined with modified Valsalva maneuver in patent foramen ovale / 中华超声影像学杂志

Objective:To comparatively analyze the diagnostic value of patent foramen ovale and the degree of right-to-left shunt among the traditional Valsalva maneuver (VM), the modified Valsalva maneuver (mVM) and the compression of the inferior vena cava combined with modified Valsalva maneuver (CM).Methods:A total of 132 patients with migraine, dizziness, chest pain and other symptoms in Longgang District People′s Hospital of Shenzhen from January 2021 to December 2021 were prospectively enrolled. The detection rate of patent foramen ovale and the degree of right-to-left shunt were assessed among the rest state and after performing the auxiliary maneuvers including VM, mVM and CM respectively.Results:After performing the auxiliary maneuvers, the detection rate of patent foramen ovale was significantly increased (88.6% vs 59.8%) with statistical significance (χ 2=36.026, P<0.001). There was a significant difference in the degree of right-to-left shunt among the three auxiliary maneuvers (χ 2=25.581, P<0.001). CM was the most effective for the detection of the large right-to-left shunt, and the difference was statistically significant compared with VM and mVM ( P<0.001, P=0.002). Conclusions:Auxiliary maneuvers is crucial for the diagnosis of patent foramen ovale. Compared with VM and mVM, performing CM can further improve the detection rate of patent foramen ovale and increase the degree of right-to-left shunt.

Dynamic Response Simulation and Damage Prediction of Pilot Cervical Vertebra During Maneuver Flight / 医用生物力学

Objective To simulate dynamic response of cervical spine of the pilot during typical maneuver flight movements using finite element method, as well as make analysis and prediction on damage failure of the pilot neck during flight by impact injury and fatigue injury model of biological tissues.Methods A geometrically accurate finite element model of the neck was constructed, and validity of the model was verified by relevant examples. Then, the acceleration curves of centrifugal trainer under different modes were loaded for numerical simulation, and impact injury and fatigue injury of tissues were predicted by using the universal cervical injury criterion and the fatigue damage model of biological tissues.Results The maximum stress of the vertebrae and intervertebral disc caused by overload impact was 66.53 MPa and 58.63 MPa respectively during typical maneuver flight. According to the Nij injury criteria, the maximum Nij was 0.096, which was lower than the injury tolerance threshold of 1, and would not cause direct acute injury to cervical tissues. Based on fatigue damage model of biological tissues, it was found that cancellous bone suffered fatigue failure under the condition of uninterrupted repeated loading for more than 40 000 times. Considering the limited flight career of the pilot, the vertebral tissues would not be fractured due to the accumulation of fatigue damage.Conclusions To a certain extent, the results can contribute to formulating pilot training and flight plans, and also provide data support for the development of its protective equipment.

Advance in chin-down maneuver in aspiration for dysphagic patients (review) / 中国康复理论与实践

ObjectiveTo identify the appropriate definition, scope of application, the mechanism and the efficacy of the chin-down maneuver in aspiration reduction or prevention. MethodsLiteratures about chin-down published before July, 2021 were reviewed. ResultsA total of 13 articles were included. Chin-down refered to the action of bending the neck and leaning the chin as far as possible toward the chest. Chin-down maneuver could change the position and pressure of the pharyngeal structure to guide the food safely into the esophagus, to prevent or reduce aspiration. Chin-down maneuver was effctive on dysphagia caused by insufficient laryngeal elevation, delayed pharyngeal reflex, epiglottal defect, lychee cartilage defect, and glottis closure defect. However, this action worked in patients with premature overflow of food clumps, weak pharyngeal contraction muscle strength, and poor oral preservation. ConclusionChin-down maneuver is beneficial to aspiration dysphagia after dysphagia.

Effects of Customized Vestibular Rehabilitation on Static balance among Adults with Benign Paroxysmal Positional Vertigo (Kesan Rehabilitasi Vestibular Disesuaikan Ke Atas Keseimbangan Static Dalam Kalangan Dewasa Dengan Masalah Benign Paroxysmal Positional Vertigo) / Jurnal Sains Kesihatan Malaysia

@#The aim of this study was to detemine the effectiveness of Customized vestibular rehabilitation (CVR) in addition to the standard Canalith repositioning maneuver (CRM) on static balance among adults with posterior canal Benign Paroxysmal Positional Vertigo (BPPV). In this randomised controlled trial, 28 adults with idiopathic unilateral posterior canal BPPV were randomized to either the control or experimental group. The experimental group (n=14, mean age: 50.71±9.88 years) received CVR in addition to CRM, and the control group (n=14, mean age: 54.36±8.55 years) received only CRM for 6 weeks. Measurements of static balance (postural sway) using a portable kinematic sensor were performed at baseline, four and six weeks after treatment for both groups while standing on firm and foam surface with eyes open (EO) and closed (EC). Only standing on foam surface with EC was observed to have a significant interaction effect, F (2, 52) =5.28, p<0.05. This suggest that the groups were affected differently by the intervention and greater improvement was demonstrated in the experimental group. Post hoc test showed that a significant difference (p<0.05) in static balance was shown between baseline and 6th week after intervention. The results of our study indicate that CVR in addition to CRM improved static balance in adults with UPC BPPV at 6th week after intervention for persons with BPPV.

Cardiovascular Physiotherapy on Respiratory Sinus Arrhythmia of Patients Undergoing Coronary Artery Bypass Grafting

Abstract Introduction: Patients in the postoperative period of coronary artery bypass grafting (CABG) present respiratory and autonomic dysfunctions. In this sense, cardiovascular physiotherapy has been offered as an indispensable differential for the improvement of the prognosis of this population. Heart rate variability is a simple, noninvasive method to analyze autonomic modulation, as well as the accentuation maneuver of respiratory sinus arrhythmia, which demonstrates the parasympathetic autonomic control over the heart. Five patients undergoing cardiac surgery performed a protocol of cardiovascular physiotherapy in the postoperative period and had their data referring to the preoperative period, the 1st and 4th postoperative days analyzed.

Zuma Modified Maneuver as a Treatment to Geotropic Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo

Abstract Introduction Benign Paroxysmal Positional Vertigo (BPPV) is the most common vestibular disorder, resulting from detached otoliths that migrate to one of the semicircular canals - canalolithiasis - or one of the cupulas - cupulolithiasis. The present study is related to lateral canal BPPVs, which may be either geotropic or apogeotropic. The geotropic variant of lateral semicircular canal benign paroxysmal positional vertigo (LC-BPPV) is attributed to free floating particles in the posterior arm of the lateral semicircular canal. Objectives To verify the possibility of employing the Zuma repositioning maneuver, with a brief modification, as an alternative treatment for geotropic LC-BPPV. Methods Seven patients with geotropic LC-BPPV were enrolled and treated with the Zuma modified maneuver. Patients were reevaluated 1 hour after a single maneuver, to confirm the resolution of vertigo and positional nystagmus. Results All seven patients achieved immediate resolution of vertigo and positional nystagmus as measured 1 hour after the application of the maneuver. Conclusion The Zuma modified maneuver was effective for geotropic LC-BPPV after a single application. The use of the Zuma maneuver for both apogeotropic and geotropic LC-BPPV may simplify the treatment of these patients.

Five-step maneuver of transthoracic single-port assisted laparoscopic lower mediastinal lymph node dissection for Siewert type Ⅱ adenocarcinoma of the esophagogastric junction / 中华胃肠外科杂志

Objective: Surgical operation is the main treatment for advanced adenocarcinoma of esophagogastric junction (AEG). Due to its special anatomic location and unique lymph node reflux mode, the surgical treatment of Siewert II AEG is controversial. Lower mediastinal lymph node dissection is one of the most controversial points and a standard technique has not yet been established. This study is aim to explore the safety and feasibility of five-step maneuver of transthoracic single-port assisted laparoscopic lower mediastinal lymph node dissection for Siewert type II AEG. Methods: A descriptive case series study was conducted. The intraoperative and postoperative data of 25 patients with Siewert type II AEG who underwent five-step maneuver of transthoracic single-port assisted laparoscopic lower mediastinal lymph node dissection in Guangdong Provincial Hospital of Traditional Chinese Medicine from January 2019 to April 2021 were retrospectively analyzed. Five-step maneuver was as follows: In the first step, the subcardiac sac was exposed; the right pulmonary ligament lymph nodes and the anterior thoracic paraaortic lymph nodes were dissected cranial to inferior pericardium, left to left edge of thoracic aorta. In the second step, the left diaphragm was opened, and a 12 mm trocar was placed through the 6-7 rib in the left anterior axillary line. The supra-diaphragmatic nodes were dissected through the thoracic operation hole. In the third step, the left inferior pulmonary ligament was severed. The anterior fascia of thoracic aorta was incised to join the anterior space of thoracic aorta formed in the first step and then the lymphatic tissue was dissected upward until the exposure of left inferior pulmonary vein. In the fourth step, the posterior pericardium was denuded retrogradely from ventral side to oral side to the level of left inferior pulmonary vein, right to right pleura, and then the right pulmonary ligament lymph nodes were completely removed. In the fifth step, the esophagus was denuded, and the esophagus was transected 5 cm above the tumor using a linear stapler to complete the dissection of lower thoracic paraesophageal lymph nodes. Results: Operations were successfully completed in 25 patients without conversion, intra-operative complication and perioperative death. Total gastrectomy was performed in 19 cases and proximal gastrectomy in 6 cases. The mean operative time was (268.7±85.6) minutes, the mean estimated blood loss was (90.4±44.2) ml, the mean time of lower mediastinal lymph node dissection was (38.6±10.3) minutes, and the mean harvested number of lower mediastinal lymph node was 5.9±2.9. The length of esophageal invasion was >2 cm in 7 cases and ≤ 2 cm in 18 cases. Eight patients (33.0%) had lower mediastinal lymph node metastasis, including 3 cases with esophageal invasion >2 cm and 5 cases with esophageal invasion ≤ 2 cm. The mean time to postoperative first flatus was (5.5±3.1) days. The average time of postoperative thoracic drainage was (5.9±2.9) days. The mean hospital stay was (9.7±3.1) days. Two patients (8.0%) developed postoperative grade IIIa complications according to the Clavien-Dindo classification, including 1 case of pancreatic fistula and 1 case of pleural effusion, both of whom were cured by puncture drainage. Conclusions: Five-step maneuver of transthoracic single-port assisted laparoscopic lower mediastinal lymph nodes dissection for Siewert type II AEG is safe and feasible. Which can ensure sufficient lower mediastinal lymph node dissection to the level of left inferior pulmonary vein.

Inside out: A successful repositioning of a chronic third-degree uterine inversion / Philippine Journal of Obstetrics and Gynecology

@#In this day and age, with the advancement of treatments and the strong campaign to discourage home deliveries, chronic uterine inversion is now considered an uncommon but life-threatening obstetric condition. In this report, we present a case of a 17-year-old primipara, who sought consultation due to prolonged and heavy vaginal bleeding. Upon speculum examination, a knob-like, fleshy, hyperemic, smooth mass, approximately 6 cm × 5 cm × 4 cm, was seen occupying the upper third of the vaginal canal. On internal examination, a globular mass was felt protruding through the cervix, which bleeds easily on manipulation. Uterine corpus was neither appreciated on both abdominal and rectovaginal examination. The patient was admitted and managed as a case of chronic uterine inversion, which was further confirmed by a sonogram. Successful repositioning of the uterus was achieved after trying different established techniques and procedures in the attempts at maneuvering the chronically inverted uterus.

This research reveals the impact of the Epley replacement jaw on people suffering from benign paroxysmal postural vertigo, 35 years of age and older. To know the quality of life, a self-perception test called Dizziness Handicap Inventory (DHI) was applied, which must be performed before and after the Epley maneuver, in order to verify whether the quality of life varied or not depending on the treatment. The methodology in the research was descriptive-comparative, since it seeks to establish the difference of the people before and after the replacement maneuver, the dimension was longitudinal and the sample was 12 people chosen in a non-random way. Regarding the results, it is observed that there is an improvement in the quality of life when comparing the results before and after treatment

Procedure and teaching verses of supraclavicular subclavian catheterization / 中华危重病急救医学

In order to improve the success rate of supraclavicular deep venous catheterization and reduce mechanical complications, we present an auxillary maneuver in regard to supraclavicular subclavian catheterization basing on the relatively fixed anatomy of subclavian vein and its adjacent surroundings, furthermore, we revised the standardized procedure of supraclavicular subclavian catheterization. The maneuver is summarized in the shape of verses (verses: thumb navigation is well designed according to anatomy. Needle penetrated into vein should be parallel to coronal plane. Fine needle in position should be immobilized. Is it difficult for parallel puncture? Pressure determination is required when needle is in place. It is critical to distinguish which vessel has been inserted. Guidewire is advanced smoothly. Check blood return after expansion of skin and catheterization.). For teaching convenience, verses are considered to be more concise and memorable, as well as applicable to clinical practice, in order to provide some help for clinical teaching.

Mareo residual, una condición clínica frecuente posterior a maniobra de reposición exitosa en vértigo posicional paroxístico benigno: una revisión / Residual dizziness, a frequent clinical condition following successful repositioning maneuver for benign paroxysmal positional vertigo: a review

El vértigo posicional paroxístico benigno (VPPB) es reconocido como la principal causa de vértigo de origen periférico en adultos, ya que, si bien la etiología del VPPB aún no se ha demostrado plenamente y se clasifica como la mayoría de los casos, se puede identificar el desprendimiento de otolitos y su desplazamiento en uno de los tres canales semicirculares. Una anamnesis cuidadosa puede abordar el diagnóstico clínico del VPPB, pero la confirmación se obtendrá por medio de maniobras de diagnóstico especificas de acuerdo a cuál de los canales está involucrado. Este trastorno altera la capacidad de llevar a cabo actividades de la vida cotidiana que determinan un aumento significativo en el riesgo de caídas y las consiguientes lesiones. La mayoría de los pacientes se recuperan después del tratamiento, sin embargo, hasta dos tercios de éstos pueden percibir inestabilidad prolongada, aturdimiento y malestar definidos como mareo residual. Esta sintomatología residual después de la resolución del VPPB es variable entre los pacientes, siendo el tiempo de duración de los síntomas residuales de aproximadamente de 1 a 3 semanas, existiendo algunos pacientes que pueden recuperarse más tardíamente. En esta revisión analizaremos el mareo residual, describiendo su expresión clínica, diagnóstica, fisiopatológica y tratamientos actuales de esta entidad clínica.

Benign paroxysmal positional vertigo (BPPV) is recognized as the main cause of peripheral vertigo in adults, although the etiology of BPPV has not yet been fully demonstrated and is classified as idiopathicin most cases, detachment of otoliths and their displacement in one of the three semicircular canals can be identifie. A careful history can address the clinical diagnosis of BPPV, but confirmation will be obtained through specific diagnostic maneuvers according to which canal is involved. This disorder alters the ability to carry out activities of daily living that determine a significant increase in the risk of falls and consequent injuries. Most patients recover after treatment, however, up to two thirds of these patients may perceive prolonged instability, dizziness and discomfort defined as residual dizziness. This residual symptomatology following BPPV resolution is variable among patients, the duration of residual symptoms can last 1 to 3 weeks, with some patients may recover later on. In this review, we will analyze residual dizziness, describing its clinical presentation, diagnosis, pathophysiology and current treatments of this clinical entity.

Síndrome de vasoconstricción cerebral reversible inducido por maniobra de Valsalva: Reporte de caso y revisión de la literatura / Valsalva maneuver induced-reversible cerebral vasoconstriction syndrome: Case report and literature review

RESUMEN El síndrome de vasoconstricción cerebral reversible es una entidad clínico-radiológica caracterizada por la presentación de cefalea severa de inicio hiperagudo tipo "trueno", con o sin signos y síntomas neurológicos adicionales en relación a una vasoconstricción arterial cerebral segmentaria que resuelve espontáneamente a los 3 meses. Por la superposición de las manifestaciones clínicas con otras entidades nosológicas, y por los múltiples factores etiológicos asociados, el diagnóstico se convierte en un reto; es imperativo realizarlo de forma temprana para la instauración de un tratamiento adecuado y la prevención de complicaciones. Se presenta el caso clínico de una paciente en quien se documentó como etiología la realización repetitiva de la maniobra de Valsalva sin otro factor concomitante, se exponen las intervenciones realizadas y se hace una revisión narrativa del tema con énfasis en el diagnóstico diferencial.

SUMMARY Reversible cerebral vasoconstriction syndrome is a clinical-radiological entity characterized by severe and hyperacute onset-thunderclap headache, with or without additional neurological signs and symptoms in relation to a segmental cerebral arterial vasoconstriction that resolves spontaneously at around 3 months. Its clinical manifestations are similar to other diseases, and additionally there are multiple associated etiological factors; early diagnosis becomes a challenge, but is essential to establish proper treatment and prevent complications. We present the case of a female patient in whom the repetitive performance of the Valsalva maneuver without another concomitant factor was documented as etiology, the interventions performed are presented and a narrative review of the topic is made with emphasis on differential diagnosis.
