ABSTRACT

OBJECTIVE@#To analyze and compare the characteristics and causes of F wave changes in patients with Charcot-Marie-Tooth1A (CMT1A) and chronic inflammatory demyelinating polyneuropathy (CIDP).@*METHODS@#Thirty patients with CMT1A and 30 patients with CIDP were enrolled in Peking University Third Hospital from January 2012 to December 2018. Their clinical data, electrophysiological data(nerve conduction velocity, F wave and H reflex) and neurological function scores were recorded. Some patients underwent magnetic resonance imaging of brachial plexus and lumbar plexus, and the results were analyzed and compared.@*RESULTS@#The average motor conduction velocity (MCV) of median nerve was (21.10±10.60) m/s in CMT1A and (31.52±12.46) m/s in CIDP. There was a significant difference between the two groups (t=-6.75, P < 0.001). About 43.3% (13/30) of the patients with CMT1A did not elicit F wave in ulnar nerve, which was significantly higher than that of the patients with CIDP (4/30, 13.3%), χ2=6.65, P=0.010. Among the patients who could elicit F wave, the latency of F wave in CMT1A group was (52.40±17.56) ms and that in CIDP group was (42.20±12.73) ms. There was a significant difference between the two groups (t=2.96, P=0.006). The occurrence rate of F wave in CMT1A group was 34.6%±39%, and that in CIDP group was 70.7%±15.2%. There was a significant difference between the two groups (t=-5.13, P < 0.001). The MCV of median nerve in a patient with anti neurofascin 155 (NF155) was 23.22 m/s, the latency of F wave was 62.9-70.7 ms, and the occurrence rate was 85%-95%. The proportion of brachial plexus and lumbar plexus thickening in CMT1A was 83.3% (5/6) and 85.7% (6/7), respectively. The proportion of brachial plexus and lumbar plexus thickening in the CIDP patients was only 25.0% (1/4, 2/8). The nerve roots of brachial plexus and lumbar plexus were significantly thickened in a patient with anti NF155 antibody.@*CONCLUSION@#The prolonged latency of F wave in patients with CMT1A reflects the homogenous changes in both proximal and distal peripheral nerves, which can be used as a method to differentiate the CIDP patients characterized by focal demyelinating pathology. Moreover, attention should be paid to differentiate it from the peripheral neuropathy caused by anti NF155 CIDP. Although F wave is often used as an indicator of proximal nerve injury, motor neuron excitability, anterior horn cells, and motor nerve myelin sheath lesions can affect its latency and occurrence rate. F wave abnormalities need to be comprehensively analyzed in combination with the etiology, other electrophysiological results, and MRI imaging.

ABSTRACT

Resumen:Las lesiones del plexo braquial son más frecuentes de lo que se pueda pensar y las padecen generalmente personas jóvenes en edad reproductiva, lo que trae consigo importante afectación a la economía no solo familiar sino también a la de la nación. Esta entidad nosológica compromete de forma grave la función del miembro superior afectado produciendo parálisis sensitiva, motora y vegetativa, en muchos de los casos se ve acompañada además de dolor neuropático intenso, lo que no redunda en la incapacidad permanente de la persona afectada, con el agravante de que los recursos terapéuticos disponibles son limitados y el pronóstico sigue siendo muy variable, con un amplio espectro de posibilidades que van desde la completa hasta la nula recuperación.


Abstract:Brachial plexus injuries are more common than you might think and usually suffer from young people of reproductive age, which brings significant effect not only to the family economy but also to the nation. This disease entity severely compromises the function of the affected upper limb producing sensory, motor and vegetative paralysis, being that in many cases is accompanied besides intense neuropathic pain, which is not in permanent disability of the person concerned, with the aggravating circumstance that the therapeutic resources are limited and prognosis is still very variable, with a wide spectrum of possibilities ranging from full recovery to zero.

ABSTRACT

Brachial plexus neuropathies are common complaints among patients seen at orthopedic clinics. The causes range from traumatic to occupational factors and symptoms include paresthesia, paresis, and functional disability of the upper limb. Treatment can be surgical or conservative, but detailed knowledge of the brachial plexus is required in both cases to avoid iatrogenic injuries and to facilitate anesthetic block, preventing possible vascular punctures. Therefore, the objective of this study was to evaluate the topography of the infraclavicular brachial plexus fascicles in different upper limb positions adopted during some clinical procedures. A formalin-preserved, adult, male cadaver was used. The infraclavicular and axillary regions were dissected and the distance of the brachial plexus fascicles from adjacent bone structures was measured. No anatomical variation in the formation of the brachial plexus was observed. The metric relationships between the brachial plexus and adjacent bone prominences differed depending on the degree of shoulder abduction. Detailed knowledge of the infraclavicular topography of neurovascular structures helps with the diagnosis and especially with the choice of conservative or surgical treatment of brachial plexus neuropathies.


Las neuropatías del plexo braquial son quejas comunes entre los pacientes atendidos en las clínicas ortopédicas. Las causas van desde traumas a factores ocupacionales y los síntomas incluyen parestesias, paresia e incapacidad funcional del miembro superior. El tratamiento puede ser quirúrgico o conservador, pero se requiere un conocimiento detallado del plexo braquial en ambos casos para evitar lesiones iatrogénicas y para facilitar el bloqueo anestésico, evitando posibles lesiones vasculares. Por lo tanto, el objetivo de este estudio fue evaluar la topografía de los fascículos del plexo braquial infraclavicular en diferentes posiciones de los miembros superiores adoptadas durante algunos procedimientos clínicos. Se llevó a cabo la disección de las regiones infraclavicular y axilar de un cadáver adulto, de sexo masculino, conservado en formaldehído. Se midió la distancia de los fascículos del plexo braquial en relación a las estructuras óseas adyacentes. No se observó variación anatómica en la formación del plexo braquial. Las relaciones métricas entre el plexo braquial y las prominencias óseas adyacentes difieren en función del grado de abducción del hombro. El conocimiento detallado de la topografía infraclavicular de las estructuras neurovasculares ayuda con el diagnóstico y sobre todo con la elección del tratamiento conservador o quirúrgico de las neuropatías del plexo braquial.

ABSTRACT

Los neurinomas del plexo braquial son tumores infrecuentes que pueden confundirse con otras lesiones de índole tumoral. Se presenta el caso de una mujer de 40 años, tratada previamente de un adenocarcinoma de mama derecha en el pasado, que en el estudio de extensión realizado 5 años después se detectó una lesión localizada en el plexo braquial derecho. La paciente se encontraba asintomática. El diagnóstico radiológico de presunción fue metástasis de adenocarcinoma mamario. Se realizó un abordaje axilar derecho descubriendo una lesión bien delimitada en el plexo braquial. Con ayuda de la monitorización neurofisiológica intraoperatoria, se observó que la lesión dependía de la rama cubital y se pudo realizar una resección completa preservando la función de dicho nervio. El estudio anatomopatológico confirmó que se trataba de un neurinoma, descartando así la existencia de metástasis. La evolución postoperatoria fue satisfactoria. Seis años después de la intervención no existe recidiva tumoral. En nuestro conocimiento este es el primer caso publicado en la literatura de un neurinoma del plexo braquial dependiente de la rama cubital. La monitorización neurofisiológica intraoperatoria resulta fundamental para abordar este tipo de lesiones con baja morbilidad.


Schwa nomas originating from the brachial plexus, although rare, may be mistaken for another type of tumour. A 40 year-old woman, who had been treated years earlier for a breast adenocarcinoma, showed in the 5-year follow-up magnetic resonance examination a localized lesion in the right brachial plexus. The presumptive radiological diagnosis was a metastasis from the primary adenocarcinoma. Following surgical access via the right axilla, a well-circumscribed mass in the brachial plexus was detected. Under intraoperative electrophysiological guidance, the lesion was observed to depend on the ulnar nerve and its complete resection was possible without compromising nerve function. Histological findings indicated a schwannoma thus ruling out the presence of metastasis. The postoperative development was uneventful and six years after surgery, the patient is to date tumour-free. To the best of our knowledge, this is the first report of a brachial plexus schwannoma arising from the ulnar branch. Intraoperative electrophysiological monitoring is essential for a good surgical outcome.

ABSTRACT

OBJETIVO: Avaliar ganho de força e amplitude de movimento do cotovelo após cirurgia de Steindler Modificada em pacientes com lesão do tronco superior do plexo braquial. MÉTODO: Foram acompanhados de 1998 a 2007 onze pacientes com lesão traumática fechada do tronco superior do plexo braquial. Todos apresentavam evolução de pelo menos 1 ano da lesão e grau de força de flexão do cotovelo que variou de M1 a M3. Os pacientes foram submetidos à cirurgia de Steindler modificada e seguidos por período mínimo de 6 meses. Realizadas avaliações pré e pós-operatórias do ganho de força muscular, amplitude de movimento do cotovelo e pontuação conforme escala DASH. RESULTADOS: Dos onze pacientes analisados, nove (82 por cento) atingiram nível de força igual ou maior a M3 (MRC). Dois (18 por cento) chegaram ao nível de força M2(MRC). Observamos que os pacientes apresentaram ganho médio de amplitude de movimento do cotovelo pós-operatória de 43,45 graus. A média de flexão do cotovelo pós-operatória foi de 88 graus. Houve melhora da função do cotovelo demonstrada na Escala DASH em 81 por cento dos pacientes do estudo. CONCLUSÃO: A cirurgia de Steindler Modificada mostrou-se eficaz no tratamento dos pacientes com lesão de tronco superior de plexo braquial, com ganho estatisticamente significativo de amplitude de movimento. Em todos os casos algum grau de ganho de força e amplitude de flexão do cotovelo, sendo tanto maior quanto maior a força muscular inicial. Nível de Evidência: Nível II, ensaio clínico prospective.


OBJECTIVE: To evaluate the gain in strength and range of motion after modified Steindler surgery of the elbow in patients with lesions of the upper trunk of the brachial plexus. METHOD: From 1998 to 2007, eleven patients with traumatic closed upper trunk lesion of the brachial plexus were studied. All the patients had development of at least 1 year of injury and degree of strength of elbow flexion ranging from M1 to M3. The patients underwent Steindler surgery with at least 6 months of follow-up. Pre- and post-operative assessments were carried out to determine gain in muscle strength, range of motion of the elbow, and DASH scale score. RESULTS: Of the eleven patients studied, nine (82 percent) achieved a level of strength equal to or greater than M3 (MRC) with good functional recovery. Two (18 percent) reached strength level M2 (MRC). We observed that the patients had an average postoperative gain in range of motion of the elbow of 43.45 degrees. The average elbow flexion after surgery was 88 degrees. There was an improvement in elbow function, as demonstrated in the DASH Scale, in 81 percent of the patients studied. CONCLUSION: Modified Steindler surgery was effective in the treatment of patients with injuries of the upper trunk of the brachial plexus, with statistically significant gains in range of motion. In all the cases studied, there was some degree of gain in strength and range of elbow flexion, the gain being correlated with the initial muscle strength. Level of Evidence: Level II, prospective clinical trial.

ABSTRACT

In this case of a male adult Caucasian cadaver, variations were noted involving the location of the C5 ventral ramus descending anterior and superolateral to the anterior scalene muscle. An unusual communicating branch was discovered that originated from C5 at the midpoint of the anterior scalene muscle, two centimeters proximal to Erb's point, to communicate with C6 and another communicating branch originating from C6 to C7. Awareness of the possibility of this variation is of great importance during certain surgical procedures. Comparison of this case with the literature is discussed.


En este caso de un cadáver adulto varón caucásico, se observaron variaciones que involucraban la localización de la rama ventral del quinto nervio cervical (C5) anterior descendente y superior lateral en relación con el músculo escaleno anterior. Se descubrió una rama comunicante inusual que se originaba a partir del C5 en el punto medio del músculo escaleno anterior, dos centímetros próximo al punto de Erb, para comunicarse con el C6 y otra rama comunicante son su punto de origen en C6 hasta C7. Conocer la posibilidad de esta variación es de gran importancia durante la realización de ciertos procedimientos quirúrgicos. Se discute la comparación de este caso con la literatura.

ABSTRACT

Axillary neuropathy due to entrapment of the nerve in the quadrilateral space is seen rarely. Here, we describe a 24-year-old patient diagnosed with isolated axillary neuropathy that mimicked quadrilateral space syndrome. Quadrilateral or quadrangular space syndrome [QSS], first described by Cahill and Palmer in 1983, was defined as the entrapment of the distal branch of the axillary nerve and the posterior humeral circumflex artery [PHCA] in the quadrangular shaped anatomic space. We tracked the follow up of the patient for one year both clinically and electrophysiologically. Our aim in reporting this case is to stress the point that cases of such a nature usually represent situations of diagnostic and treatment challenges, where multidisciplinary approaches are required

ABSTRACT

Con el fin de comparar la analgesia posoperatoria de fentanyl y neostigmina por vía axilar del plexo braquial, se estudiaron 81 pacientes programados para cirugía del miembro superior en el Hospital Militar Central Dr. Carlos J. Finlay durante el año 2004. Divididos en 3 grupos de igual número a todos se les realizó el proceder con mepivacaína 1 por ciento (5 mg/kg); a los incluidos en el grupo 2 se les añadió fentanyl 2,5 µg/mL de solución anestésica y a los del grupo 3 neostigmina 500 µg. Se analizó duración, calidad y efectos secundarios. El tiempo medio fue de 503, 631 y 691 min respectivamente y se alcanzó analgesia buena en el 67 por ciento de los pacientes del grupo neostigmina a diferencia del grupo control (33 por ciento) y del fentanyl (44 por ciento). Los efectos secundarios se presentaron solo en el grupo fentanyl (11 por ciento) y en forma de prurito. La asociación de neostigmina brindó mejor analgesia posoperatoria.


With the objective of comparing postoperative analgesic effects of Fentanyl and Neostigmine through axillary brachial plexus block, 81 patients scheduled for upper limb surgery at Dr Carlos J. Finlay central military hospital in 2004 were studied. They were divided into three groups of equal number each; the surgical procedure was performed in all of them by using 1 percent mepivacaine (5 mg/kg); fentanyl (2,5 µg/mL) was added to those included in No. 2 group and neostigmine (500 µg) was included in the no. 3 group. Duration, quality and side effects were analyzed. Mean time was 503, 631 and 691 minutes respectively; unlike the control group (33 percent) and the fentanyl group (44 percent), satisfactory analgesic condition was found in 67 percent of patients in the neostigmine group. The group subjected to fentanyl was the only one with side effects (11 percent) in the form of itching. The addition of neostigmine offered better postoperative analgesia.

ABSTRACT

Chronic neck and arm pain or cervicobrachialgia commonly occurs with the degeneration of cervical spine. Authors investigated the usefulness of radiofrequency (RF) neurotomies of cervical medial branches in patients with cervicobrachialgia and analyzed the factors which can influence the treatment outcome. Demographic data, types of pain distribution, responses of double controlled blocks, electrical stimulation parameters, numbers and levels of neurotomies, and surgical outcomes were evaluated after mean follow-up of 12 months. Pain distribution pattern was not significantly correlated with the results of diagnostic blocks. Average stimulation intensity was 0.45 V, ranging from 0.3 to 0.69, to elicit pain response in cervical medial branches. The most common involvement of nerve branches was C4 (89%), followed by C5 (82%), C6 (75%), and C7 (43%). Among total of 28 patients, nineteen (68%) reported successful outcome according to outcome criteria after 6 months of followup (p=0.001), and eight (42%) of 19 patients reported complete relief (100%) of pain. Four patients showed recurrence of pain between 6 and 12 months. It was therefore concluded that cervical medial branch neurotomy is considered useful therapeutic modality for the management of cervicobrachialgia in selected patients, particularly in degenerative zygapophyseal disorders.

ABSTRACT

Lateral cervical cysts containing squamous cell carcinoma is a diagnostic and therapeutic challenge for the clinician since they usually represent a cystic metastasis from an occult carcinoma. Various imaging modalities or even blind biopsies will help identify the primary tumour. If the primary tumour is identified, an appropriate treatment decision can be made that incorporates both the primary tumour and the cervical node. If the primary remains unidentified, the neck is treated with a modified or radical neck dissection, depending on the extent of metastatic disease, and radiation therapy is administered to Waldeyer's ring and both necks. We present in this paper, a case with a large cervical cyst where histology showed the presence of a poorly differentiated squamous cell carcinoma in the wall of the cyst. A diagnostic evaluation of the patient was negative. Blind biopsies of the right tonsil revealed occult squamous cell carcinoma. The patient was treated by combined chemo/radiotherapy and she is doing well nine months following excision of the mass. The relevant literature is briefly reviewed.

ABSTRACT

Desde 1980 hasta 1994, fueron efectuadas 109 reparaciones directas de parálisis de Erb (C5 C6) asociada o no con daño de C7. El promediode edad en este estudio fue de 35 años, encontrándose la mayoría de los pacientes entre los 16 los 25 años. El tiempo transcurrido desde la lesión hasta la reparción varió desde 1 día hasta 1 año y 6 meses. La reparción quirúrgica se efectuó interponiendo injertos nerviosos entrelas raíces lesionadas y los nervios distales a reparar. Ningún resultado pudo ser calificado como muy bueno. Se obtuvieron buenos y medianos en 62 pacientes (59.6 por ciento). Encontrándose los peores resultados cuando cuando la reparación se hizo tardíamente. Pese a una buena recuperación 43 pacientes cambiaron de trabajo y 25 no volvieron a tener ninguna ocupación

ABSTRACT

El plexo braquial es una estructura nerviosa compleja que incluye desde las raíces cervicales hasta los nervios periféricos de la axila. Su valoración mediante métodos de imagen ha sido difícil, hasta la aparición de la RM. Es importante contar con un equipo de alto campo y bobinas de superficie que permitan obtener imágenes de alta resolución, debiendo siempre realizarse un examen en los tres planos del espacio. Este método ha probado ser útil en el diagnóstico de avulsión, neuromas, tumores, neuritis y fibrosis actínica entre las patologías más frecuentes

ABSTRACT

Os autores descrevem o caso de uma mulher branca de 40 anos de idade, com paraplegia espástica, hiperreflexia, sinal de Babinski bilateral, hipoestesi superficial e profunda em T4, além de incontinência fecal e urinária, desde os 32 anos decorrente de aracnoidite crônica adesiva (CAA). Aos 38 anos passou apresentar sudorese excessiva com limite superior em T4, diária, com intensificaçao noturna. Um bloqueio simpático lombar foi efetuado com 4mL de bupivacaina 0.5 por cento. Quinze minutos depois a paciente apresentou monoparesia braquial direita e síndrome de Horner ipsolateral. Devido provavelmente a um espaço peridural estreito e errático, secundário à CAA, pode-se justificar o quadro clínico como secundário à ascensao cranial do anestésico, mesmo utilizado em reduzida quantidade (4mL).

ABSTRACT

Aún existen dudas en el manejo de Plexo Braquial. Se publican en este trabajo algunas experiencias obtenidas al analizar 32 pacientes atendidos desde abril de 1986 hasta marzo de 1989 con lesiones traumáticas de esta parte del S. N. Periférico. Con base en los conocimientos extractados de la literatura y la experiencia adquirida, se propone una agrupación y clasificación sencilla de las lesiones abiertas(A) y las cerradas(B) con una orientación terapéutica. Se insiste en la necesidad de un buen diagnóstico topográfico, para lo cual se presenta un mapa de localización lesional, insistiendo en la importancia de los esquemas y los exámenes clínicos y paraclínicos, especialmente los estudios eléctricos. Las recomendaciones más valiosas para quienes deben tratar a estas graves lesiones, de acuerdo a lo expuesto son: Enfrentarse positivamente al problema. Clasificar la lesión para buscar el mejor camino terapéutico. Seguir la regla de las tres E (Exámenes, esquemas y evolución) en pacientes dudosos. Suturar el periostio después del abordaje-reseccioón transclavicular

ABSTRACT

Se trata de un caso de paciente transferido del Hospital departamental del Norte S.F.P por fiebre, la que fué tratada sin éxito como fiebre tifoidea; días después se instaló una disminución de la fuerza proximal del brazo derecho, acompañado de dolor en la cintura escapular ipsilateral. Los exámenes auxiliares no demostraron la etiología de la fiebre. Se destacan los hallazgos en las enzimas séricas, la biopsia del músculo clínicamente más afectado, los potenciales evocados somatosensoriales de ambos nervios medianos. El cuadro clínico, la evidencia electromiográfica de lesión de la raíz C5 y el incremento de las gammaglobulinas en el proteinograma electroforético, sugerirían un fenómeno parainfeccioso con alteración en la inmunidad, que pudo haber desarrollado una alteración autoinmune. Se revisan las características clínicas, pronóstico y terapia de esta importante y poco frecuente entidad
