Midterm rusults of endovascular treatment for ilio-femoral venous postthrombotic syndrome / 中华普通外科杂志

ABSTRACT

Objective To evaluate clinical outcome of patients treated with endovascular dilation and stent placement for ilio-femoral venous postthrombotic syndrome (PTS).Methods 42 PTS cases were enrolled in our group from June 2003 to December 2011.Dilation and stent placement in stenosis/ occlusion of ilio-femoral veins were performed in all cases,temporary femoral arteriovenous fistula was established in 24 cases.Results These were not severe perioperative complications.All patients were followed up for 8-75 months.Preoperative limb ulcers in 5 cases were healed.Early thrombosis in stents found in 3 cases was cleared by catheter directed thrombolysis (CDT).Severe in-stent restenosis (＞ 50％)was found in 10 cases,treated with dialation or re-stenting.Primary patency,assisted primary patency and secondary patency rates were 75％,78％,80.1％;64.1％,67.1％,69.6％;63.8％,65.3％,66％;61.7％,65％,65.2％,respectively,at 6 months,12 months,24 months and 36 months.Postoperative Venous Clinical Severrity Score (VCSS) decreased (P =0.000).There was statistical significant improvement in every dimension evaluated by the MOS item short from health survey(SF-36) after operation (P =0.000).Conclusion Ilio-femoral venous stenting is a safe and effective treatment for PTS and with good clinical midterm results.
