What happens if the subclavian vein is blocked?

A condition caused by repetitive arm motion This tissue causes the vein to narrow and restrict blood flow, leading to the formation of blood clots. Left untreated, axillo-subclavian vein thrombosis can cause: Arm pain and fatigue. Arm swelling.

What causes subclavian vein compression?

If you have a narrow passageway, overusing your arm and shoulder can squeeze (compress) or aggravate the subclavian vein. This compression can block blood flow and lead to clots. Other causes of venous thoracic outlet syndrome can include: Carrying extra weight (obesity), which puts extra pressure on your joints.

What causes Paget schroetter syndrome?

The syndrome also became known as “effort-induced thrombosis” in the 1960s, as it has been reported to occur after vigorous activity, though it can also occur due to anatomic abnormality such as clavicle impingement or spontaneously. It may develop as a sequela of thoracic outlet syndrome.

What is right subclavian vein?

The right subclavian vein is joined by the right lymphatic duct at the right venous angle, which drains lymph from the right upper quadrant of the body (right side of the head, neck, thorax, right upper extremity).

Is subclavian vein a deep vein?

Veins considered to be “deep” classically have a corresponding named artery. In the upper extremity the deep veins include the paired radial veins, paired ulnar veins, paired brachial veins, axillary vein, and subclavian vein.

What does the subclavian vein do?

The primary function of the subclavian vein is to drain deoxygenated blood from the upper region of the body—including the arms and the shoulder areas—and transport it back to the heart. 6 Another important function of the subclavian is to collect lymph fluid from the lymphatic system from the internal jugular vein.

What happens if the subclavian artery is compressed?

Chronic compression causes repetitive injury to the subclavian artery wall, which can potentially result in stenosis or thrombosis. Progressive damage to the arterial wall can lead to aneurysm formation, ultimately resulting in local occlusion or distal embolization.

Is Paget-schroetter serious?

Paget-Schroetter is a rare diagnosis in the general population; however, it is more common in younger, physically active individuals. Clinicians must be familiar with the symptoms, physical examination, and initial imaging and treatment to expedite care and prevent possible life-threatening complications.

How is Paget-schroetter syndrome treated?

Treatment involves anticoagulation, catheter-directed thrombolysis, and surgical decompression. Early diagnosis and treatment can improve symptoms and quality of life.

Where does right subclavian vein drain?

The subclavian vein is a paired large vein, one on either side of the body, that is responsible for draining blood from the upper extremities, allowing this blood to return to the heart….
