Retrievable inferior vena cava filter utilization in obstetric patients

AbstractObjectives: The objective of this study is to evaluate patterns of use and outcomes of retrievable inferior vena cava filters (rIVCF) in obstetric patients.Methods: A single center review of consecutive patients who underwent rIVCF placement during pregnancy/postpartum in 2005–2016. A pooled analysis of the relevant cases in the English literature was conducted.Results: The current cohort comprised 24 women, median age 27 [interquartile range 24–30] years. Among 10 filters placed during pregnancy, the most common indication (n = 4) was the need to withhold anticoagulation therapy before delivery, in the presence of acute thrombosis. In the postpartum period, most filters (64%, 9/14) were an adjunct to catheter-directed thrombolytic therapy. Inferior vena cava filters (IVCF)-related complications occurred in seven (29.2%). Retrieval was attempted in 21 patients (87.5%), and was technically successful in 19 (90.5%), for an overall removal rate of 79.1%. Pooled analysis of the literature (n = 98) sho...
