Clinical correlation of the area of inferior vena cava, iliac and femoral veins for stent use:

ObjectiveThe purpose of the study is to evaluate normal anatomical areas of infrarenal inferior vena cava, common iliac, external iliac and common femoral veins by intravascular ultrasound with the goal of assisting the development of venous-specific stents in the treatment of iliac vein stenosis.MethodFrom February 2012 to December 2013, 656 office-based venograms were performed in our facility. Among them, 576 were stented and 80 were not. The measurements of veins were done intraoperatively using an intravascular ultrasound catheter to record areas of the inferior vena cava, proximal, middle and distal segments of common iliac vein, external iliac vein and common femoral vein. The data were compared between non-diseased segments of patients who were stented and those not stented. The stented diseased segments were excluded.ResultsThe mean patient age was 67.33 years (range 22–96, SD ±13.99). Our data included 218 males, 438 females and 324 right lower extremities and 332 left lower extremities. The pre...
