The IDC coil is an effective device that allows controlled embolization to be performed, especially in aneurysms and high-flow arteriovenous fistulas.Once the conventional microcoil emerges from the catheter tip, a stage of irreversibility is soon reached because catheter withdrawal means coil deployment. IDC coil, which is the controlled-release coil, has been developed to overcome this major limitation. The IDC is released when the coil pusher is advanced until the radiopaque marker on its distal end is superimposed on the proximal marker of the microcatheter. When necessary, the coil can be easily retrieved before the two markers, and may be pushed forward again. However, this system sometimes causes premature detachment, which is a considerable risk, and coil repositioning can cause problems. In this paper, we summarized the possible IDC-related complications and introduced some basic troubleshooting procedures for these problems.
