Primary subclavian venous thrombosis which developed after sleeping with the arm in an outstretched position: Report of a case

Primary subclavian venous thrombosis is more rare than secondary thrombosis . This type of thrombosis is called "effort. thrombosis" or Paget-Schroette r syndrome, and develops after a strenuous effort of the superior limb. A d ay after a 55-year-old man got drunk and slept in the left lateral position in combination with an abducted and elevated position of the left superior limb, he became aware of swelling and an oppressive feeling in his left su perior limb and was admitted 9 days later. Thrombus of the left axillary-su bclavian vein was confirmed by venography, and thrombolytic therapy with ur okinase was performed immediately. The left arm symptoms improved for the m ost part. Venography after the therapy revealed thrombolysis at the site of the axillary vein, while the subclavian vein enhanced the collateral vesse l pathway. The patient was discharged on the seventh hospital day, and anti coagulant therapy with oral warfarin sodium has since been continued. This is considered to be a rare case of subclavian venous thrombosis caused by s leeping in an abnormal position with the arm outstretched.
