title: Surgical thrombectomy and simultaneous stenting for deep venous thrombosis caused by iliac vein compression syndrome (May-Thurner syndrome).
abstract: OBJECTIVE
  Iliac vein compression syndrome (May-Thurner syndrome) is characterized by left iliac vein obstruction secondary to compression by the right common iliac artery against the fifth-lumbar vertebra, which increases incidence of deep venous thrombosis (DVT). We treated the patients with DVT due to May-Thurner syndrome (MTS) by surgical thrombectomy and simultaneous stenting, and this study is to evaluate the outcomes of this procedure.
  
  
  METHODS
  From January 2009 to December 2011, a total of 8 patients underwent surgical thrombectomy with stenting. All patients were admitted for acute DVT involving the left iliofemoral segment, and diagnosed MTS. Patients were followed-up, and stent patency was assessed by means of duplex sonography.
  
  
  RESULTS
  In all patients, the procedure was successful in achieving re-canalisation of the iliofemoral veins at the end of the operation. Perioperatively, there was no mortality and there was no case of clinically detected pulmonary embolism. Rethrombosis occurred within seven days of operation in 2 patients. During the follow-up period (mean; 16 months), 6 of 8 patients kept patent stents.
  
  
  CONCLUSIONS
  Venous thrombectomy with simultaneous stenting is a potent technique to treat acute iliofemoral DVT due to MTS. This technique can restore venous patency and provide relief of the acute symptoms.
