A new approach of extracting embolized venous catheters using a large-diameter steerable sheath under biplane fluoroscopy

To report the efficacy of a new percutaneous technique for extraction of embolized catheters, five female patients (62±14 years) referred to our institution were analyzed. With the combination of a large-diameter steerable sheath with a sizeable snare system, three dislodged Port-A-Cath tubes and two ventriculoatrial shunts were retrieved successfully. Mean procedure time was 51±23 min, biplane fluoroscopy time was 22±21 min, and dose area product was 1188±992 dGy cm(2). Percutaneous extraction of embolized venous catheters is highly effective with the help of this novel, self-assembled system. The presented technique provides major advantages with respect to three-dimensional steerability and should be considered for complex cases.
