A pre-procedure review of available images should be performed to ensure that the patient has favorable anatomy for IVCF placement and that the vena cava is of a suitable size to meet the IFUs for the intended device. Review of any available CT scan of the abdomen is helpful to predetermine IVC diameter, possible venous anomalies, suitability for bedside techniques, and IVCF selection. Pre-procedure extremity venous duplex ultrasound should be reviewed for the presence and location of DVT and to confirm a femoral access site free of thrombus. Based on review of pre-procedural imaging, if there are any concerns that bedside IVCF placement is not feasible, venographic guidance techniques should be used.
