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. The left subclavian vein plays a key role in the absorption of lipids , by allowing products that have been carried by lymph in the thoracic duct to enter the ...
[5] Diagnosis commonly occurs in early adolescence, expressed as symptoms such as deep vein thrombosis occurring spontaneously. [4] The mainstay diagnosis of the presenting DVT symptom is an ultrasound with venous Doppler. [4] Ultrasound with venous Doppler rarely identifies the inferior vena cava anomalies present from birth. [4]
Ambesh maneuver is a technique that involves the simple external compression of internal jugular vein in supraclavicular fossa to prevent [1] and diagnose [2] misplacement of the subclavian vein catheter into the internal jugular vein (IJV). The subclavian vein is a big vessel that drains the blood from the hand, forearm and the upper arm into ...
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet.

When a thrombus occludes an extremity vein, pressure backs up in the venous system leading plasma fluid to leak out into the interstitium of the affected limb. This increases the pressure of that limb compartment, which can collapse the arteries and lead to acute ischemia , gangrene , hypovolemia , and hemodynamic instability.
Vascular occlusion is a blockage of a blood vessel, usually with a clot. It differs from thrombosis in that it can be used to describe any form of blockage, not just one formed by a clot. When it occurs in a major vein , it can, in some cases, cause deep vein thrombosis .
Central retinal vein occlusion and branch retinal vein occlusion: despite the name these conditions have much more in common with arterial thrombosis and are not treated with anticoagulants; Paget–Schroetter disease: thrombosis of the veins of the arms (axillary and subclavian veins) Budd-Chiari syndrome (thrombosis of the hepatic vein)
Repetitive motions can cause enlargement of muscles which causes compression of veins. Besides, overuse injury of the upper limbs causes swellings, small bleeding, and subsequent fibrosis which would cause the thrombosis of the subclavian vein, leading to Paget–Schroetter disease or effort-induced thrombosis.
