Presentation
A duplex ultrasound was performed due to concerns about upper limb ischemia.
Patient Data
Findings:
left internal jugular vein; normal color flow, compression, and grayscale appearance
left brachial and subclavian veins; both veins are partially thrombosed with grayscale imaging showing echogenic material adherent to the vessel wall, partially filling the lumen of the vein
left axillary vein; normal color flow, compression, and grayscale appearance
Impression: non-occlusive thrombosis of the peripheral portion of the left subclavian vein and the central portion of the brachial vein.
Case Discussion
Upper extremity deep vein thrombosis (UEDVT) accounts for less than 6% of all deep vein thrombosis (DVTs). UEDVT may be complicated by post-thrombotic syndrome and pulmonary embolism; as a result, prompt recognition and treatment are necessary. Risk factors for UEDVT include strenuous activities, hypertrophied scalene muscles, and anatomical abnormalities. Treatment includes anticoagulation.
