From Open Evidence, an AI medical website I use.
A blood clot in the shoulder typically refers to a deep vein thrombosis (DVT) in the upper extremity, specifically involving the veins of the shoulder region, such as the subclavian, axillary, or brachial veins. This condition can arise due to various factors, including trauma, surgery, or repe ive strain.
One specific type of upper extremity DVT is Paget-Schroetter syndrome, also known as effort thrombosis, which is often seen in athletes or individuals engaging in repe ive upper limb activities. This syndrome involves thrombosis of the subclavian vein and presents with symptoms such as painful swelling, discoloration, and visible collateral veins in the affected arm.[1-2]
