Abstract
Treatment of the post-thrombotic syndrome (PTS) is mainly conservative therapy such as patient education that utilizies self-management techniques and compression therapy, but its impact sometimes is limited. We performed endovascular therapy (EVT) of the iliofemoral vein using a balloon and a stent for two cases of PTS (CEAP clinical class 3, contraindication for compression therapy). Thrombolytic agent was not administered because of the thrombus was organized. After successful EVT, leg swelling receded within three days. EVT for PTS is an effective therapy for symptomatic patients.
