IVCFs placed during pregnancy were frequently in the suprarenal position, in 5 (71%) cases. Meanwhile, 16 (94%) were deployed in an infrarenal position prior to pregnancy and postpartum. Complications included multiple attempts to remove the IVCF (n\u2009=\u20092), severe angulation (n\u2009=\u20094), embedded struts (n\u2009=\u20093), fracture (n\u2009=\u20091), and one case of cardiac tamponade (n\u2009=\u20091).
