A 30 year old tennis instructor presents with right arm pain. After doing repetitive overhand serves, he gets forearm fatigue. This is accompanied by swelling, pain, and cyanosis. He notes paresthesias in the fingers occasionally. He also says he can see "blood draining from his arm through his shoulder, neck, and chest wall." A duplex ultrasound confirms your diagnosis. You start the patient on anticoagulation and refer to a surgeon.
Challenge: What's the diagnosis?

Venous thoracic outlet syndrome?
I'm not sure what Dx would be given.
But it definitely sounds like its a hyperextension injury, with neurological and atrial involvement...thrombosis (i want to say axillary, but it doesn't sound completely right to me) if you are starting the patient on an anti-coagulant.
No idea what the overall Dx would be though.
thoracic outlet syndrome due to hypertrophy of muscle around thoracic outlet i.e. scalene muscle..
oh, and the obstruction of subclavian vein makes the blood flow stagnant and could lead to emboli formation
great comments - yes is thoracic outlet syndrome

Terms of Service
This is TOS or thoracic outlet syndrome (also called cervical rib syndrome, scalene anticus syndrome, costoclavicular syndrome, and hyperabduction syndrome) resulting from compression of the neurovascular bundle above the first rib and behind the clavicle. Although the brachial plexus, subclavian artery, or subclavian vein can be affected, venous compression is described in this case.

thought u would also invoke " Paget-Schroetter disease" as one of the AKAs.
