The purpose of this scientific statement is to provide an up-to-date overview of the postthrombotic syndrome (PTS), a frequent, chronic complication of deep venous thrombosis (DVT), and to provide practical recommendations for its optimal prevention, diagnosis, and management The intended audience for this scientific statement includes clinicians and other healthcare professionals caring for patients with DVT

Members of the writing panel were invited by the American Heart Association Scientific Council leadership because of their multidisciplinary expertise in PTS Writing Group members have disclosed all relationships with industry and other entities relevant to the subject The Writing Group was subdivided into smaller groups that were assigned areas of statement focus according to their particular expertise After systematic review of relevant literature on PTS (in most cases, published in the past 10 years) until December 2012, the Writing Group incorporated this information into this scientific statement, which provides evidence-based recommendations The American Heart Association Class of Recommendation and Levels of Evidence grading algorithm (Table 1) was used to rate the evidence and was subsequently applied to the draft recommendations provided by the writing group After the draft statement was approved by the panel, it underwent external peer review and final approval by the American Heart Association Science Advisory and Coordinating Committee External reviewers were invited by the American Heart Association The final document reflects the consensus opinion of the entire committee Disclosure of relationships to industry is included with this document (Writing Group Disclosure Table)
