Upper extremity venous occlusion
Upper extremity venous occlusion describes a condition in which the vein coming from the arm into the chest becomes narrowed, blocked or pinched. It is usually seen in people who use their arms in repetitive tasks, such as swimming or house painting. The overuse of the muscles results in thickening that can pinch the vein where it enters the body from the arm, just above the first rib.
Reduced flow of blood from the arm is usually acute, causing pain, swelling, or discoloration of the arm. It requires immediate medical attention to restore proper blood-flow.
The condition is known by several names, including: Paget-von Schröetter Syndrome, upper extremity deep vein thrombosis (DVT), axillo-subclavian vein thrombosis and effort thrombosis. It mostly occurs in young people.
