Endovascular Management of Deep Venous Thrombosis

School of Medicine, Southern Illinois University, Springfield, Illinois, rmclafferty@ siumed.edu

The past decade has witnessed new developments for the treatment of deep venous thrombosis (DVT) as well as more information about the virulent nature of DVT over the long term. Symptoms of pain, edema, skin changes, and/or ulceration can affect upwards of 70% of individuals to some degree. Studies have determined that early intervention of thrombus removal may help prevent postthrombotic syndrome in a significant number of patients. Several devices now specifically combine mechanical or ultrasound energy with chemical thrombolysis. These devices include the Trellis-8, Angiojet Power Pulse System, and the Ekos Endowave. Other important aspects central to successful endovascular removal of DVT include using ultrasound guidance for access, understanding venous anatomy and physiology in relation to endovascular techniques, knowing when to perform venous interventions, and using intravascular ultrasound. Endovascular removal of DVT is increasingly becoming the standard of care, particularly that affecting the iliofemoral segments.

Key Words: deep venous thrombosis • thrombolysis • mechanical • chemical • syndrome • ultrasound
