Single-Session Mechanical Thrombectomy of Lower Extremity Deep Venous Thrombosis Using the ClotTriever System: A Single-Institution Experience
Funding None.
Abstract
Purpose The aim of this study was to provide a single-center experience in utilization of the ClotTriever mechanical thrombectomy system in acute and subacute deep vein thrombosis (DVT).
Methods Retrospective review was performed for all patients who underwent DVT thrombectomy using the ClotTriever system at a single academic medical center. Data recorded included age, gender, etiology, laterality of DVT, fluoroscopy time, perioperative parameters, type of anesthesia, concomitant usage of thrombolytics and/or stents. Follow-up Doppler ultrasounds or diagnostic venograms were reviewed, and time of reintervention (if performed) and Villalta scores were recorded.
Results Ten patients were included in the study, with 6/10 female (60%), mean age 54.6 years (range: 24–80). Eight patients presented with acute iliofemoral DVT, one patient with subacute iliofemoral DVT, and one patient with subacute inferior vena cava thrombosis. Only one patient required concomitant intraprocedural thrombolytic administration, and four patients underwent same-session venous stent placement. Technical success was achieved in 90% patients and no procedure-related adverse events were observed. Reintervention within 30 days was required in two (20%) patients at 12 and 13 days. No patient required intensive care unit (ICU) stay, and mean postprocedure hospital length of stay was 2.3 days. On follow-up (mean: 214 days), five patients had no evidence of DVT and four patients showed chronic postthrombotic changes in femoropopliteal veins not requiring intervention.
Conclusion The ClotTriever mechanical venous thrombectomy system demonstrates high efficacy in removal of thrombus from lower extremities in a single session, often obviating the need for thrombolytic therapy with low reintervention rates and short postprocedure hospital stay.
