Additionally, other studies could compare clinical outcomes between procedures performed in an office based angiosuite and other settings.
Thoracic outlet syndrome may associate neurologic, arterial and venous symptoms. The responsibility of repetitive movements and postural factors has been mentioned for long. Some tasks are hard to perform, and it seemed interesting to assess the consequences of this syndrome on the work capacity by a questionnaire, at the moment of diagnosis by Echo-Doppler
This study will determine the value of TOD (first rib resection with partial scalenectomy and neurolysis) on functionality and quality of life for patients with neurogenic thoracic outlet syndrome. This will be done by randomizing patients into surgery or conservative therapy (physiotherapy and pain relief).
The measurement of the transcutaneous oxygen partial pressure (TCPO2) at exercise is, to our knowledge, the only method to estimate during the exercise the importance of ischemia segment of limb by segment of limb bilaterally and carry on. The diagnosis of thoracic outlet syndrome causing remains difficult and dependent operator in ultrasound because of the risk of false positive (loss of signal) or false negative (insufficient effort, inappropriate movement). Our main hypothesis is the existence of significant measurable ischemia in the forearm by transcutaneous oximetry during the maneuvering of the "candlestick". In the event of failure of this maneuver, the other maneuvers such as those of Wright, Roos, Tinel and Adson will be realized. In this study we want to evaluate the possibility of using dynamic transcutaneous Oximetry as a tool for evaluating ischemia in case of suspicion of thoracic outlet syndrome causing.
Botulinum toxin type A injected into the anterior and middle scalene muscles will reduce the irritation on the neurovascular structures at the interscalene triangle in subjects with TOS. This will lead to reductions in pain and paresthesias, and improvements in function when compared with injection of placebo.
Thoracic Outlet Syndrome (TOS) is a condition causing numbness, tingling and weakness in patient's upper limbs. Symptoms are due to compression and restriction of the nerves and blood vessels (neurovascular bundle) that extend from the neck into the upper limb exerted by a patient's various anatomical structures. Neurovascular bundle compression can result in decreased nerve conduction and blood flow through the arteries supplying structures downstream from the restricted site. These anatomical restrictions include tight scalene muscles in the neck, tightened pectorialis minor muscle in the chest and extra ribs growing from the C7 vertebra. TOS can be diagnosed by using special tests designed to re-elicit neurovascular bundle compression. Upon obtaining a positive test, the patient can undergo osteopathic manipulative treatments (OMT) to change the anatomical restrictions allowing for a decrease of symptoms and even eradication of the syndrome altogether. Although diagnosis and treatment of TOS is common in osteopathic medicine, the effectiveness of the diagnostic special tests and treatment has not been thoroughly investigated. This study aims to examine the effectiveness of the special tests (Adson's, Wright's hyperabduction and Halstead maneuver) in diagnosing a change in blood flow through the arteries of the upper arm compared to evaluation with Doppler ultrasound to measure blood flow while the tests are performed. Patients with positive tests will be treated with OMT including myofascial release, soft tissue, and articulation to relieve restricting structures. Upon completion of treatment, the special tests will be performed again along with the Doppler ultrasound to measure blood flow through blood vessels. Results then are analyzed statistically for significance of the ability correctly diagnose and treat TOS symptoms. Results from this study will contribute towards the validity of teaching special tests in osteopathic medical schools and allow for a non-invasive treatment protocol for patients with TOS.
Thoracic outlet syndrome is caused by compression of the brachial plexus, in most cases under the pectoralis minor muscle in the infraclavicular region of the shoulder. The hypothesis is that ultrasound imaging can be used to visualize brachial plexus compression and distortion of the pectoralis muscle during arm activity, such as abduction, and that normal subjects will not demonstrate any plexus compression or muscle distortion.
The purpose of this study is: 1. To assess the effect of BOTOX injection to the scalene muscles on the severity of pain from TOS. 2. To assess the effect of BOTOX injection on numbness and tingling and quality of life.
