Mechanical thrombectomy with the ClotTriever System for upper extremity deep vein thrombosis: A case series

Patients with upper extremity deep vein thrombosis (UEDVT) generally present with similar symptoms including arm swelling, erythema, heaviness, or pain. However, this condition is caused by different factors which can influence management decisions. As a result, UEDVT is categorized by primary or secondary etiology. Primary UEDVT is most commonly a result of anatomical subclavian vein compression, whereas secondary UEDVT is most frequently associated with indwelling catheters. Regardless of etiology, anticoagulation therapy is recommended, and interventional treatment is reserved for more severe cases. This series includes outcome data for 8 heterogenous patients treated for UEDVT with mechanical thrombectomy using the ClotTriever System by an interventional radiologist in a single healthcare system. Herein we present procedural imaging for select cases and discuss treatment characteristics and outcomes based on etiology.
