Intraoperative venous balloon angioplasty during surgical thoracic outlet decompression in Paget-Schrötter syndrome.

The management of primary subclavian-axillary vein thrombosis is controversial. Indications and time of operative or endovascular intervention after successful thrombolysis remain unresolved. To improve the long-term functional outcomes in patients with primary subclavian-axillary vein thrombosis, early reestablishment of venous patency and prevention of recurrent thrombosis are required. We present a case in which, after catheter-directed thrombolysis, positional venography showed costoclavicular compression of the subclavian vein. At the time of surgical thoracic outlet decompression, transluminal venous angioplasty was performed.
