Stent fracture after endovascular treatment patient with subclavian vein thrombosis – difficult diagnosis and complication of venous thoracic outlet syndrome

Subclavian vein thrombosis is relatively rare. It constitutes 4 to 10% of all cases of venous thrombosis and is often associated with compression or canniulation of the subclavian vein. We present the case of patient with Paget-Schroetter syndrome treated in our center for right subclavian vein thrombosis as a result of the venous thoracic outlet syndrome (VTOS). In the case described below, VTOS was unrecognized and the stent fracture following endovascular treatment led to a relapse of venous thrombosis. Secondary angioplasty and stenting with subclavian vein decompression was successfully made. The patient was regularly monitored throughout the following year and there was no relapse of clinical symptoms. Conclusions: in case of subclavian vein thrombosis decompression is a very important step in the management of VTOS. It prevents recurrence of thrombosis and potential complications.
