Event Description
|
It was reported that the coil protruded in the catheter's tip upon removal.A 10mm x 40cm and 15mm x 40cm interlock-35 coils were selected for ventral aorta branch covered stent implantation, left and right internal iliac artery embolization, and aortography.During the procedure, a 15mmx40cm coil was pushed to the neck of the main abdominal tumor, but it could not be further advanced, which could go back but not forward.Embolization could not be completed with the internal iliac artery, so a 10mmx40cm was used to superselect the right iliac through the left femoral artery.However, the first 10cm were smooth, but the position was not suitable and could not be advanced after multiple attempts.Furthermore, when the coils were removed from the patient's body, it was noted that the coils protruded from the tip of the catheter.The procedure was completed with another of the same device.No complications were reported, and the patient was stable post-procedure.
