title: Combined use of electrolytically and mechanically detachable platinum coils for endovascular treatment of cerebral aneurysms--technical note.
abstract: The combined use of Guglielmi detachable coils (GDCs) and newly developed mechanically detachable platinum coils (Detach Coil System: DCS) was evaluated for the endovascular treatment of 10 patients with cerebral aneurysms. The number and total length of detachable coils placed into the aneurysms, the detaching time for each coil, and any technical problems were recorded and evaluated. Sixty GDCs and 60 DCSs were used. The detachment time for the DCS (mean 21 seconds) was faster than that for the GDC (mean 2 minutes 35 seconds). One DCS moved inside the aneurysm during the mechanical detachment maneuver, but was successfully placed. Neither detachment system influenced the behavior of the other system during coil implantation. The DCS includes a useful J-shape coil, whereas the GDC can be detached safely in fragile aneurysms. The DCS is also cheaper. The coil systems complemented one another and the combination optimized cost and operating time.
