Abstract

The electrolytically detachable platinum coil (Guglielmi Detachable Coil: GDC) is a safe and efficient endovascular tool for treatment of cerebral aneurysms. However, the GDC still has some problems, including a prolonged detaching time and high cost. The Detach Coil System (DCS) is a newly developed platinum detachable coil for the treatment of neurovascular diseases. This has a mechanical "screw" detachment system, which can be detached faster than the GDC, The platinum coil is mounted to the tip of the delivery wire by the "screw" system. For detaching the coil, 20 - 25 times anti-clockwise rotation of the delivery wire using a "detach locking device" is required. We report our preliminary clinical experience of using the DCS in 11 patients. This series included 5 sacral aneurysms, 3 dissecting aneurysms, and 3 dural arteriovenous fistulas. Seventy-five coils were used in total, of which 5 coils were retrieved and 70 coils were implanted. The detaching time of each DCS was 15 - 20 seconds, which was much faster than that of the GDC. All lesions were successfully treated without symptomatic complications. In the limited number of cases, our result suggest that the DCS allowed safe and fast endovascular treatment of neurovascular disease at a lower cost.
