Catheter-directed thrombolysis combined with manual aspiration thrombectomy for acute inferior vena cava filter thrombosis.

Background: The occurrence of inferior vena cava (IVC) filter thrombosis has been reported, however, the optimal treatment of IVC thrombosis has not been established yet. The aim of this study was to assess the results of catheter-directed thrombolysis (CDT) combined with aspiration thrombectomy (AT) in the treatment for IVC filter thrombosis.

Methods: A total of 35 consecutive patients received endovascular treatment with CDT alone or CDT with AT for IVC filter thrombosis at Second Affiliated Hospital of Suzhou University from May 2009 to May 2014 were included in this study.

The incidence of pulmonary embolism in patients with combined lower extremity deep venous thrombosis and iliac vein compression syndrome.

Background: The aim of this study was to investigate the risk of symptomatic pulmonary embolism (PE) in patients with combined lower extremity deep vein thrombosis (DVT) and iliac vein compression syndrome (IVCS).

Methods: Between January 2011 and February 2014, 399 patients diagnosed with combined lower extremity DVT and IVCS at the Second Affiliated Hospital of Soochow University were included in this retrospective study. The odds of symptomatic PE versus combined lower extremity DVT and IVCS were assessed using logistic regression models.
