ABSTRACT

Deep vein thrombosis (DVT) of the upper limb is a rare entity, estimated to account for 10% of all cases of DVT. Classically, they are classified into primary (idiopathic, due to subclavian vein compression or exercise related) and secondary (cancer, thrombophilia, trauma, shoulder surgery, associated to venous catheters or due to hormonal causes). The Paget- Schrötter syndrome is a primary thrombosis of the subclavian vein in the subclavian-axillary junction, related either to repetitive movements or to exercise; leading to microtrauma in the endothelium with consequent activation of the coagulation cascade. Clinically, it presents abruptly with pain, edema and feeling of heaviness in the affected limb. The treatment varies from thrombolytics and anticoagulation to surgical intervention, depending on the time of evolution. We present four cases of exercise-related subclavian vein thrombosis.
