AbstractInferior vena cava filters (IVCFs) have been used clinically for approximately 45 y, but only a few studies of these devices have involved intensive care unit (ICU) patients who were critically ill and had multiple-organ dysfunction or were otherwise too unstable for transport. The purpose of this research was to assess the tolerability and efficacy of bedside ultrasound-guided IVCF placement in ICU patients. A retrospective analysis of both bedside ultrasound-guided and X-ray-guided ICVF placement was performed from November of 2011 to August of 2013. The total success rate for ultrasound-guided IVCF placement was 93.4%, which included a 96.0% success rate in 25 ICU patients with an average age of 69.46 y. Six-month follow-up studies revealed no significant differences in long-term complications between the ultrasound- and X-ray-guided groups. IVCFs may be safely implanted under ultrasound guidance in a monitored ICU environment. Our conclusion is that patients should be fasting and should receive an enema and that pre-operative surface marking and dynamic monitoring should be employed. Further research is needed to develop specific ultrasound guidelines.Copyright © 2015 World Federation for Ultrasound in Medicine & Biology. Published by Elsevier Inc. All rights reserved.
