目的:了解桡神经浅支卡压的依据并讨论了该征的诊断及治疗原则。方法:解剖观测了20具40侧成人上肢标本桡神经浅支穿出处的局部解剖特点及其距桡骨茎突的距离,随访了12例患者,9例采用局部封闭治疗,3例采用手术神经松解治疗。结果:桡神经浅支穿出部位为腱性组织所包绕。该处筋膜将肱桡肌腱挤在一起,从而易于受压。临床随访6个月至2年,保守及手术治疗患者症状均完全消失无复发。结论:解剖:桡神经浅支在前臂中下段易发生卡压有其解剖学基础。临床上病程短症状轻患者保守治疗往往能有较好疗效,病程长症状重或存在其它病理性压迫患者往往需要手术治疗。 相似文献

Upper plexus thoracic outlet syndrome--case report 总被引:2,自引:0,他引:2
A 47-year-old right-handed female became aware of proximal ache and muscle weakness in the right shoulder and elbow in 1997. Atrophy of the right biceps muscle was recognized and the right deltoid, triceps, supraspinatus, and infraspinatus muscles were weak. The Morley test and elevated arm stress test were positive. Neurolysis of the brachial plexus and anterior scalenectomy were performed via a right supraclavicular approach. An abnormal fibromuscular band was identified passing between the upper and middle trunks and constricting the middle trunk. Another scalene muscle anomaly was found passing between the C-5 and C-6 nerve roots and connecting the anterior and middle scalene muscles. These muscles were resected, and thorough neurolysis was performed around all nerves and the trunks. Postoperatively, all symptoms completely resolved and the patient was discharged 5 days after surgery. Thoracic outlet syndrome (TOS) manifests as symptoms of lower cervical nerve involvements with hypesthesia and paresthesia. However, upper plexus TOS manifests as symptoms due to the involvement of the C-5 to C-7 nerve roots, and is relatively rare. Transaxillary first rib resection is performed as the primary operation for TOS, but supraclavicular scalenectomy is effective for upper plexus TOS. 相似文献

Background
The diagnosis and validation of thoracic outlet syndrome/brachial plexopathy (TOS) remains a difficult challenge for surgeons, neurologists, and radiologists. This is due to the fact that the responses of standard elevated arm stress tests can be considered somewhat subjective and can vary. Therefore, non-vascular TOS cases are presently diagnosed clinically, and any objective diagnosis has been controversial.Methods
This is a technique paper describing the use of dynamic neuromusculoskeletal ultrasound to assist in the diagnosis of thoracic outlet/brachial plexus pathology. We propose a new way to observe the brachial plexus dynamically, so that physical verification of nerve compression between the anterior and middle scalene muscles can be clearly made at the onset of clinical symptoms. This gives a way to objectively identify clinically significant brachial plexus compression.Results
Dynamic testing can add objective analysis to tests such as the elevated arm stress tests and can correlate the onset of symptoms with plexus compression between the anterior and middle scalene muscles. With this, the area of pathologic compression can be identified and viewed while performing the dynamic testing. If compression is seen and the onset of symptoms ensues, this is a positive confirmatory test for the presence of TOS and a clinically significant disease.Conclusions
This paper offers a simple, objective, and visual diagnostic test that can validate the presence or absence of brachial plexus compression during arm elevation in patients with brachial plexus injury and thoracic outlet syndrome. 相似文献16.

臂丛神经的交感神经支配及其临床意义 总被引:11,自引:4,他引:7
目的:了解颈交感神经在臂丛神经上的分布并探讨其对臂丛神经活动的影响及引起颈肩痛的机制。方法:对30具60例成人尸体标本,大体和显微镜解剖颈部的交感神经;并对2具4例新鲜成人尸体进行颈部局部封闭。结果:支配臂丛神经的交感社会支主要来自颈下节和颈中节。颈中节到臂丛的分支大部分紧贴或穿过前、中斜角肌,部分穿入椎孔后加入臂丛。颈下节的分支则绕过锁骨下动脉或椎动脉后到达臂丛。局部封闭后发现药物浸润范围主要在颈椎横穿尖部或前侧。结论:颈交感神经到达臂丛神经的分支与颈部软组织的解剖关系密切,软组织活动会影响交感社会对臂丛的支配,并可引起颈肩痛。 相似文献

Applying ultrasound imaging to interscalene brachial plexus block 总被引:11,自引:0,他引:11
Chan VW 《Regional anesthesia and pain medicine》2003,28(4):340-343
OBJECTIVE: Previous studies have examined ultrasound-assisted brachial plexus blocks, but few have applied this imaging technology to the interscalene region. We report a case of interscalene brachial plexus block using ultrasound guidance to show the clinical usefulness of this technology. CASE REPORT: A nerve stimulator-guided interscalene block was attempted for arthroscopic shoulder surgery but failed. Subsequent nerve localization was accomplished by ultrasound imaging using a high-frequency probe (5-12 MHz) and the Philips ATL HDI 5000 unit. Ultrasound showed nerves between the scalene muscles, block needle movement at the time of advancement, and local anesthetic spread during injection. Interscalene block was successful after 1 attempt of nerve localization and needle placement. CONCLUSIONS: Advanced ultrasound technology is useful for nerve localization and can generate brachial plexus images of high resolution in the interscalene groove, guide block needle placement and advancement in real time to targeted nerves, and assess adequacy of local anesthetic spread at the time of injection. Ultrasound imaging guidance can potentially improve success during interscalene brachial plexus block. 相似文献

Thoracic outlet syndrome (TOS) is not a single disorder but a collection of abnormalities in the same anatomic area that elicit similar symptoms. The many causes of TOS are best classified into one of three groups: osseous, traumatic, and nontraumatic. Although patients with traumatic TOS constituted 86% of our last 600 patients with TOS who underwent surgical treatment, the precise mechanism underlying the condition remains obscure. To determine if there was microscopic abnormalities, 45 anterior and middle scalene muscles from patients with traumatic TOS were studied by means of histochemical stains applied after freezing of the muscles. The results revealed a consistent abnormal histologic pattern in patients with traumatic TOS: type II fibers were atrophied; there was an increase in the average number of type I fibers (78% versus 53% in muscles from control patients); and there was a significant increase (mean: 36%) in connective tissue (muscles from control patients averaged less than 15%). Although type II fiber atrophy and type I fiber predominance are seen in a variety of other conditions, their association with fibrosis is rare. Following neck injuries, the changes in the anterior and middle scalene muscles are compatible with trauma, suggesting that fibrotic scalene muscles are an important cause of symptoms in traumatic TOS. 相似文献

Patients with thoracic outlet syndrome (TOS) who improve temporarily after anesthetic blockade of the anterior scalene muscles have been shown to improve after ultimate surgical decompressions at the interscalene triangle. Anesthetic blockade of the scalene muscles, even with the addition of steroids, however, rarely produces any prolonged relief as patients are awaiting definitive surgery. The present study was undertaken to determine if more effective and prolonged relief might be obtained with electrophysiologically and fluoroscopically guided selective injection of the scalene muscles with botulinum toxin, which has been used in the past for treating conditions associated with spasm of cervical muscles. In 14 of 22 patients (64%) with a clinical diagnosis of TOS, there was more than a 50% reduction of symptoms measured by a 101-point scale for at least 1 month after botulinum chemodenervation of the scalene muscles. Only 4 of the 22 patients (18%) had a 50% reduction of symptoms for at least 1 month after injection with lidocaine and steroids. In no patient were the results of lidocaine and steroid injection superior to botulinum chemodenervation. Chemodenervation had a mean duration of effect of 88 days. No significant side effects were encountered with botulinum chemodenervation except for mild transient dysphagia in two cases. These results appear to demonstrate that botulinum chemodenervation of the scalene muscles may be helpful in alleviating symptoms in patients with TOS awaiting definitive surgical decompression. 相似文献
