“…Use of balloons or stents to assist coil embolization allows the prevention of coil protrusion from the aneurysm orifice and safe and proper embolization for difficult aneurysms 1,2 . The stretch resistance (SR) function helps to prevent unraveling on coil withdrawal 3 . This function is very useful when last coil must be retrieved or repositioned after it is squeezed between the coil complexes.…”

The Mechanism of Catheter Kickback in the Final Stage of Coil Embolization for Aneurysms: The Straightening Phenomenon

et al. 2010

The catheter kickback phenomenon often occurs in the last stage of coil packing for cerebral aneurysms. This behavior is considered the result of either a lack of space in the sac or a stiff detaching zone. In order to clarify its mechanism, focused stretch-resistance (SR) coil simulation models were tested. Various commercially available SR coils were inserted into a cylinder or an aneurismal sac made from a silicone tube with a smaller than prescribed diameter. A magnified SR coil model (straight type) of fishing line was created for simulation. Numerical analysis for the changes in coil behavior were verified. All SR coils showed hardening and straightening at the last few millimeters, resulting in catheter kickback. In a magnified coil experiment, straightening was also realized when folding into a narrow cylinder. The SR line coursed in the canal of the first loops and shifted to the outside in the middle portion. Gaps among first coil pitches were enlarged on after insertion into the narrower space. Shortage of the SR line was calculated to reach a maximum of 32%. The straightening phenomenon is due to SR line shortening and subsequent condensation of pitches of the first loops at the coil end. Coil tail flexibility was lost, and the coil behaved as a stiff wire. Straightening is an important factor in the kickback phenomenon. Shorter final SR coils should be selected, and coil designs should be improved.
