Thoracic Outlet Syndrome Management and Treatment Strategies

Thoracic Outlet Syndrome (TOS) encompasses neurogenic, venous and arterial compressive disorders of the brachial plexus and subclavian vessels as they traverse the thoracic outlet. Initial assessment relies on a detailed history, focused clinical examination and selective imaging to distinguish the predominant subtype. Conservative management remains the first-line approach for the majority of cases, combining tailored physiotherapy programmes to correct postural abnormalities, pain relief with non-steroidal anti-inflammatories and, where indicated, injection therapies such as local anaesthetic or botulinum neurotoxin. Refractory or advanced presentations may benefit from surgical decompression, most commonly via first rib resection with scalenectomy or pectoralis minor tenotomy, delivered through open, endoscopic or minimally invasive techniques. Evidence from systematic analyses indicates that, in venous forms, catheter-directed thrombolysis followed by decompressive surgery achieves higher rates of symptom resolution compared with anticoagulation alone. Long-term functional outcomes after surgical intervention are satisfactory in most patients, although some residual impairment can persist. Multidisciplinary care in specialised centres supports individualised decision-making, optimises perioperative safety and facilitates rehabilitation, enhancing global applicability of evolving protocols.

Thoracic Outlet Syndrome Management and Treatment Strategies publication trend

The graph below shows the total number of articles in thoracic outlet syndrome management and treatment strategies across all publications each year (not limited to Nature Index journals).

Technical terms

Neurogenic TOS: Compression of the brachial plexus leading to pain, paresthesia and weakness in the upper limb.

Venous TOS: Obstruction of the subclavian vein, often resulting in thrombosis and limb swelling.

Catheter-directed thrombolysis: Infusion of clot-dissolving medication directly into a thrombosed vessel via a catheter.

First rib resection: Surgical removal of the first rib to decompress the thoracic outlet.

Botulinum neurotoxin: Microbial toxin used in targeted muscle injections to reduce spasm and relieve neurovascular compression.
