Avoiding Renal Vein Entry When Implanting the Mobin-Uddin Vena Cava Umbrella Filter

• Transvenous placement of a Mobin-Uddin vena cava umbrella filter is a safe and effective method of vena cava interruption in high-risk patients who cannot undergo laparotomy. When the renal veins enter the vena cava acutely, there may be preferential passage of the filter insertion device into the aberrant renal veins. If the usual maneuvers of changing the patient's position do not correct this aberrant passage, then a venous thrombectomy catheter may be used to temporarily occlude the vein orifice. This technique avoids the problems of incorrect placement and abandonment of the transvenous approach to vena cava interruption.
