The future of deep venous thrombosis and post-thrombotic syndrome in 2020.

This manuscript addresses six major issues involving deep venous thrombosis (DVT) and post-thrombotic syndrome. Prevention will likely see modest advances in pharmacological therapy, mainly by extending prophylaxis in high-risk patients. More notable advances will be observed in mechanical means of prophylaxis, focusing on sustained application of devices that can move larger volumes of blood. Silent, large-vein thrombi continue to place patients at risk for fatal pulmonary embolism. Improved imaging techniques will permit us to identify these patients over the next eight years. In many of those patients, vena caval interruption will be required. Elimination of high-risk filters and the production of improved filters placed through low-profile systems with antithrombotic agents bound to their surface will improve the short- and long-term results for inferior vena cava filters. The long-term management of DVT will focus on establishing appropriate duration for the individual patient and will see the evolution towards direct Xa and IIa inhibitors. Patients with extensive DVT will more commonly receive treatment strategies designed to eliminate thrombus and restore patency. This will substantially reduce post-thrombotic morbidity and reduce recurrence. Post-thrombotic syndrome will see greater attention towards treating the intraluminal fibrosis, thereby eliminating post-thrombotic venous obstruction. Unfortunately, neovalves will still be searching for the appropriate application.
