Subclavian thrombosis/SVC Syndrome is characterized by a set of symptoms that arise due to obstruction of the superior vena cava, which can occur due to a thrombosis, often as a result of compression or an underlying condition. This obstruction hampers venous return from the head, neck, and upper extremities, leading to a classic presentation that includes arm pain, tingling, edema particularly in the face and upper extremities, and possibly distended neck veins.

The presence of arm pain and tingling is indicative of compromised circulation and neurologic involvement due to pressure on nearby structures. The edema of the face is a direct reflection of fluid accumulation due to the obstruction in venous drainage, which aligns with the pathophysiology of subclavian thrombosis/SVC Syndrome. This condition can be exacerbated by physical compressive factors, such as tumors or vascular access devices, which are common in patients who require infusion therapy.

Understanding this condition is vital for nurses practicing in infusion therapy settings, as timely recognition can prevent complications associated with prolonged obstruction and ensure prompt intervention.
