Evaluation of the Influence of Body Position on the Inferior Vena Cava (IVC) Diameter

NCT01995877 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 2

Last updated 2017-05-04

No results posted yet for this study

Summary

To determine if laying down or standing up changes the diameter of the inferior vena cava.

Conditions

  • Vena Cava Filters

Interventions

PROCEDURE

Subjects scheduled for IVC filter placement

Subjects will have an intra vascular ultrasound (IVUS) performed while lying down on the exam table; this will be performed before and after the IVC (inferior vena cava) filter is placed. During the ultrasound, measurements of the diameter of different areas of the IVC will be taken. The table will then be moved so that you are in a standing position and the measurements will be taken again. The ultrasound will be done by the physician performing your procedure. When you are lying down, a sheath (small catheter) will be inserted into a vein in your groin. The IVUS (intra vascular ultrasound) catheter will be inserted through the sheath and used to measure the size of the IVC at various places. The IVUS procedure will add about 30-45 minutes to the filter placement procedure.
