The Venous Thrombectomy Armamentarium: An Expanding World

Abstract

Acute deep venous thrombosis (DVT) is a common and important public health problem. It affects more than 350,000 people in the United States annually and has a substantial economic impact. Without adequate treatment, there is significant risk of development of post-thrombotic syndrome (PTS) resulting in patient morbidity, worse quality of life, and costly long-term medical care. Over the past decade, the treatment algorithm for patients with acute DVT has significantly changed. Prior to 2008, the treatment recommendation for patients with acute DVT was limited to anticoagulation and conservative management. In 2008, national clinical practice guidelines were updated to include interventional strategies such as surgical- and catheter-based techniques for the treatment of acute DVT. Early strategies for debulking of extensive acute DVT primarily consisted of open surgical thrombectomy and administration of thrombolytics. In the intervening period, a plethora of advanced endovascular techniques and technologies have been developed which reduced the morbidity of operative intervention and risks of hemorrhage associated with thrombolysis. This review will focus on the novel technologies commercially available for management of acute DVT, denoting unique features inherent to each device. This expanded armamentarium gives vascular surgeons and proceduralists the opportunity to individualize their treatment approach to the specific patient's anatomy, lesion, and history.
