Outcome of Endovascular Treatment in Postthrombotic Syndrome

BackgroundThe postthrombotic syndrome (PTS) is a chronic complication of deep venous thrombosis (DVT) that is characterized by leg swelling and ulceration.MethodsSixty-seven cases of PTS underwent attempted endovascular treatment with success in 63 between June 2005 and June 2012. Thirty-six cases underwent endovascular treatment only and 18 cases combined with temporary femoral arteriovenous fistula, 5 cases great saphenous vein ligation and stripping whereas 4 cases with communicating branch ligation around ulcers.ResultsStenting was successfully performed in 63 of 67 patients. The technical success rate was 94% with no mortality. Fifty-eight cases were followed up from 1 to 84 months. Stent occlusion or restenosis occurred in 17 patients. The primary and secondary patency rates were 87.9% and 93.1%, respectively, at 12 months and 70.7% and 82.8%, respectively, at 36 months.ConclusionsEndovascular treatment of PTS is safe and effective. It can alleviate symptoms and prevent further deterioration of patients with PTS.
