Superior vena cava syndrome (SVCS), is a group of symptoms caused by obstruction of the superior vena cava ("SVC"), a short, wide vessel carrying circulating blood into the heart. The majority of cases are caused by malignant tumors within the mediastinum , most commonly lung cancer and non-Hodgkin's lymphoma , directly compressing or invading ...
A positive Pemberton's sign is indicative of superior vena cava syndrome (SVC), commonly the result of a mass in the mediastinum.Although the sign is most commonly described in patients with substernal goiters where the goiter "corks off" the thoracic inlet, [4] the maneuver is potentially useful in any patient with adenopathy, tumor, or fibrosis involving the mediastinum.
In a French population, the percent of people with SVTs that also suffered from PEs was 4.7%. [3] In the same population, deep vein thrombosis (DVT) was found in 24.6% of people with SVTs. [ 3 ] However, because superficial veins lack muscular support, any clots that form are far less likely to be squeezed by muscle contraction, dislodged, and ...
After proximal DVT, an estimated 20–50% of people develop the syndrome, with 5–10% experiencing severe symptoms. [165] Post-thrombotic syndrome can also be a complication of distal DVT, though to a lesser extent than with proximal DVT. [166] In the 10 years following an initial VTE, about 30% of people will have a recurrence. [3]
The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart. It is a large-diameter (24 mm) short length vein that receives venous return from the upper half of the body, above the diaphragm .

People with thrombophlebitis complain of pain along the affected area. Some report constitutional symptoms, such as low-grade fever and aches.
