Direct superior vena cava puncture for inferior vena cava filter retrieval

Most inferior vena cava (IVC) filters are designed for retrieval from a superior approach. Retrieval becomes technically challenging when the central veins in the chest are occluded. In a patient with thrombosis of the bilateral brachiocephalic veins, the authors describe direct puncture of the superior vena cava (SVC) under fluoroscopy, followed by the successful retrieval of a fractured IVC filter using forceps. A snare inserted into the SVC via the common femoral vein was used as a radiopaque target for direct SVC puncture from the lower neck. Cone beam computed tomography and pullback tractography were used to confirm a safe access trajectory. Thus, direct SVC access may be used for filter retrieval in similar clinical scenarios.
