“…Primary UEDVT includes the following disease entities: Paget-Schroetter syndrome (effort thrombosis), thoracic outlet syndrome (TOS) and cases of idiopathic UEDVT. In the 19 th century, Sir James Paget (1814-1899) and Leopold von Schroetter (1837-1908) described venous obstruction in the upper extremity, which in 1949, Hughes [ 2 ] called Paget-Schroetter syndrome (thrombosis of the axillary – subclavian vein). Paget-Schroetter syndrome is also known as “effort-induced thrombosis”, because it is frequently associated with an extreme physical effort [ 3 ] in young males who are involved in active sport games, such as long-distance swimming, wrestling, handball, baseball, badminton, rowing, weight lifting or body building exercises.…”
