Subclavian Vein Thrombosis Extending into the Internal Jugular Vein: Paget-von Schroetter Syndrome

Paget-von Schroetter syndrome refers to spontaneous thrombosis of the subclavian vein and constitutes 0.5-1% of all venous thromboses. It is prevalent among young and healthy adult males who engage in sports. Early diagnosis and treatment is essential to avoid long-term sequelae. Herein, we report a 42-year-old male weightlifter who presented with swelling of the left arm, pain and a feeling of tightness in the anterior chest wall. At Doppler US and MR angiography, subclavian vein thrombosis extending into the internal jugular vein was detected. Thrombolytic treatment ensured continuous venous flow and the patient's complaints decreased.
