Medical News Today: What to know about thoracic outlet syndrome
Thoracic outlet syndrome occurs when something compresses the nerves, arteries, or veins that pass through the thoracic outlet. Learn more about this condition, including symptoms and treatment options, here.

ConclusionsDuplex ultrasound has significant limitations in the initial evaluation of patients with suspected SCV thrombosis, with false-negative results in 21% of patients with proven VTOS. This is rarely acknowledged in ultrasound reports, but false-negative ultrasound studies have the potential to delay definitive imaging, thrombolysis, and further treatment for VTOS. Initial false-negative ultrasound results are associated with progressive thrombus extension and a more frequent need for SCV bypass reconstruction at the time of surgical treatment.Graphical Abstract
ConclusionMRI can contribute to the diagnosis of TOS. Specificity is sufficiently high to provide guidance for planning the surgical procedure. Sensitivity, however, is too low for MRI to be useful as a screening test. MRI should be used in combination with the clinical assessment and other investigations to assist in the diagnosis of TOS.Level of evidenceIV, retrospective cohort study.
Rationale: Venous thoracic outlet syndrome (VTOS) secondary to subclavian arterial stent implantation is extremely rare. Here, we firstly report this disease and the endovascular intervention using covered-stents. Patient concerns: An 80-year-old man who had received an acceptable stent implantation for the treatment of a right subclavian arteriovenous malformation (AVM), presented with a gradually increasing swelling and pain in his right upper extremity. Diagnosis: The patient was diagnosed with right VTOS and recurrent subclavian AVM following ultrasonography and computed tomographic angiography. Interventions:...

Upper extremity deep vein thrombosis (DVT) results from pathologic compression of the subclavian vein at the costoclavicular junction.1-3 Also known as Paget-Schroetter syndrome, this pathology is associated with high morbidity and severe symptoms.2-5 The military population is particularly susceptible given the prevalence of young, healthy service members performing rigorous physical activity and training. Our group has previously reported significant functional recovery following supraclavicular decompression for neurogenic thoracic outlet syndrome (NTOS) in the high-performance military population.
Neurogenic thoracic outlet syndrome (NTOS) is a condition caused by compression of the brachial plexus serving the upper extremity. Diagnosis and therapy of NTOS remain disputed. Moreover, surgical treatment (thoracic outlet decompression) has never been researched in a randomized controlled trial. The recently published reporting standards for thoracic outlet syndrome by the Society for Vascular Surgery aim to produce consistency in diagnosis, description of treatment, and assessment of results to allow more valuable data to be reported.
