Key result
Mechanical thrombectomy with ClotTriever clears UEDVT and salvages a malfunctioning CVC in a single session.
Why the study?
Consistent guidelines regarding the management of UEDVT are lacking, and treatment is often individualized based on patient characteristics, clinical factors, and technical considerations.
Case Report (n=1)
The ClotTriever System can be used to successfully treat upper extremity deep venous thrombosis and simultaneously salvage a malfunctioning central venous catheter in a single session.
Single-session thrombectomy with catheter salvage appears feasible; hypothesis-generating and requires prospective validation before clinical adoption.
Intravenous catheters account for the majority of cases of upper extremity deep vein thrombosis (UEDVT), with a higher incidence in patients suffering from malignancy. Sequelae of UEDVT are similar to that of lower extremity DVT, comprising post-thrombotic syndrome and pulmonary embolism. While there are several treatment options for UEDVT including systemic anticoagulation, catheter-directed thrombolysis, and percutaneous mechanical thrombectomy, due to the absence of consistent guidelines regarding its management, treatment is often individualized based on patient characteristics, clinical factors, and technical considerations. We present a case of a 49-year-old female suffering from breast cancer with a central venous catheter (CVC) who came to the clinic with UEDVT and CVC malfunction and was successfully treated with mechanical thrombectomy using the ClotTriever System (Inari Medical, Irvine, CA). To our knowledge, this is the first report of the ClotTriever System being used to treat UEDVT and simultaneously salvage the CVC in a single session.

Agarwal et al. (2020) conducted a case report in Upper extremity deep vein thrombosis and central venous catheter malfunction (n=1). ClotTriever System was evaluated on Venous patency and symptom resolution. Percutaneous mechanical thrombectomy using the ClotTriever System successfully treated upper extremity deep vein thrombosis and salvaged a malfunctioning central venous catheter in a single session.
