“…Çoğu olguda median ve ulnar motor sinir iletim hızları normaldir. Urschel ve Caldwell gibi çeşitli araştırıcıların 1971 yılında bildirilen yayınlarında özellikle ulnar sinir motor iletim çalışmalarının üzerinde durulmuştur (4,5). Bu çalışmalarda hastalarda segmental motor iletim hızın-da yavaşlama saptanmıştır.…”

Thoracic outlet syndrome (TOS) is a complex entity that is characterized by different neurovascular signs and symptoms involving the upper limb. TOS can be difficult to diagnose because there is no standardized objective test that can be used and the clinician must rely on history and several positive findings on physical exam. Electrophysiological study is useful in the diagnosis of neurogenic TOS.Reduced amplitude of medial antebrachial cutaneous nerve and ulnar nerve sensory nerve action potentials (SNAPs), predominant denervation in thenar eminency, and reduced amplitude of compound motor action potentials (CMAPs), more by median than by ulnar stimulation, are correlative with the diagnosis. Electromyographic studies showed a reduced recruitment pattern of motor unit activation in intrinsic hand muscles. Especially, electrophysiological assessment can help exclude conditions that may mimic nTOS, such as ulnar nerve entrapment or cervical radiculopathy.

Thoracic outlet syndrome as defined in English literature is a set of symptoms which arise in consequence of the compression/irritation of subclavian artery and vein and or brachial plexus along the vertebral to axillary region of the apertura thoracis superior. As well three different types of thoracic outlet had been defined: Neurogenic (90-95%); vascular (5-10%) and mixed (20%). Thoracic outlet syndrome is a source of disagreement among clinicians regarding its incidence, diagnosing benchmarks and optimal treatment. Thoracic outlet syndrome is a highly controversial subject. It is quite a rare clinical situation having a percentage of 0.3-0.7. But its real incidence is still controversial. Because objective confirmatory tests are often lacking. Hence the exact incidence is not known and the thoracic outlet syndrome is sad to be overdiagnosed by some authors and underdiagnosed by the others. In this text we would like to describe especially mixed type but also the other thoracic outlet syndrome categories according to clinical presentations, diagnosing methods and treatment modalities briefly.
