Thoracic outlet syndrome (TOS): what are the treatment options?

Written by: Mr Mohamed Abdelhamid

Thoracic outlet syndrome (TOS) can lead to symptoms that include pain and tingling or weakness in your shoulder and arm. There are three types of the condition and each requires different treatment, which could involve physiotherapy, medications or even surgery in some cases. Here, one of our leading consultant vascular surgeons Mr Mohamed Abdelhamid describes the possible treatment options for each type of TOS.


What are my treatment options for TOS?

The types of TOS include neurogenic TOS, venous TOS and arterial TOS. Let’s look at the treatment options for the three sub-types:

Neurogenic TOS

If you are at risk of developing TOS (because of the nature of your job or from sport), avoid repeated movements and lifting heavy weights. Losing weight is important to prevent or relieve symptoms of TOS. Avoiding lifting heavy bags over the shoulder, stretching and daily exercises to strengthen the shoulder muscles can all help to relieve or avoid symptoms.

Physiotherapy can cause relief of muscle spasm, improve postural imbalance, improve arm mobility and reduce the strain exposure. This should be carried out by experienced and specialised physiotherapist who is familiar with these cases.

Medications, such as pain killers and muscle relaxants should be prescribed by your doctor.

Surgery is indicated when conservative measures have failed in improving the symptoms after several months and in the presence of persistent disabling symptoms that interfere with daily activities. The aim of surgery is to relieve the pressure of the brachial plexus. This is achieved by removing the compressing agent e.g. scalene muscles, part of the first rib, any fibrous band or extra rib (cervical rib).

Venous TOS

Any young and middle-aged patient with upper limb deep vein thrombosis (DVT) should be investigated for the possibility of venous TOS until proven otherwise. Patient with upper limb DVT should be considered for thrombolysis (clot-busting) as long there are not contra-indicated. Once the clot is dissolved, the patient should receive anticoagulation (blood thinning medication) to prevent recurrence of a blood clot.

If venous TOS was found to be the cause of the arm DVT and the clot has dissolved, surgical treatment should be considered as it provides the definitive management for venous TOS.

This is the same as in neurogenic TOS with the goal of decompressing the subclavian vein and collateral venous blood flow in addition to the restoration of normal blood flow through the subclavian vein.

Arterial TOS

If arterial TOS is diagnosed before any complication e.g. blood clot blocking the blood flow, the patient should start on oral anticoagulation (blood thinners tablets) to prevent any blood clot.

This should be followed by considering surgical decompression of the subclavian artery by removing the compressing factor. If the subclavian artery has developed small swelling (aneurysm), the subclavian artery should be repaired by bypass operation. The decompression and bypass will be carried out in the same setting.

If the patient had a blood clot blocking the blood flow to the hand, the patient should be hospitalised to start blood thinners by injection (heparin) and the patient will require thrombolysis (clot-busting) or surgical removal of the blood clot (embolectomy). After this, decompression surgery and repair of the subclavian artery should be considered.

Vascular surgery

Mr Mohamed Abdelhamid is a highly skilled and practised consultant vascular and endovascular surgeon who is based at several highly regarded London clinics. With over 20 years' experience, he has gained a leading level of expertise in all aspects of his field including varicose veins surgery, thread (spider) veins, abdominal aortic aneurysm, carotid artery disease, thoracic outlet syndrome and peripheral vascular disease.

His medical training began at Cairo University Medical School, where he graduated with Honours in 1998. After, he underwent a research and Masters degree followed by basic and higher surgical training at the Cairo University Hospital. Then, in 2004, Mr Abdelhamid relocated to the UK and pursued research at the University of Birmingham as well as general and vascular surgical training in London. During his time in London, he worked in all major vascular units and his intensive training involved the opportunity to work for two years as an endovascular fellow at Sir Charles Gairdner Hospital in Perth, Australia, which he completed in 2017.

As well as dedicating his career to providing the utmost care to his patients, he also devotes his profession to medical research. In fact, he has several publications in high impact vascular journals and has given presentations on a national and international level at vascular surgery meetings and conferences. This contribution to research consists investigation of diabetic food treatment, varicose veins treatment, peripheral vascular disease among other topics . What's more, he offers courses to GPs in the areas of venous problems in primary care and vascular disease management.
