Abstract
OBJECTIVE: We describe the mechanical detachment of 2 Guglielmi detachable
coils (GDC) that had been placed in a ruptured aneurysm and that failed to detach
by electrolysis.
METHODS: Mechanical detachment was attempted by continuously rotating the delivery
wire. The feasibility and reproducibility of this maneuver was tested by conducting
additional in vitro tests.
RESULTS: Two GDCs that had been positioned in a ruptured cerebral aneurysm and
had failed to detach by electrolysis were separated from the delivery wire by rotating
the wire until the weakest segment of the coils broke. GDCs tested in vitro with correct
detachment positioning could be separated from the microcatheter tip by approximately
15 rotations of the delivery wire without coil loop movement inside the aneurysm.
CONCLUSION: Mechanical detachment of an electrolytic GDC by rotating the delivery
wire until a break occurs can be safely performed in a potentially risky situation
caused by detachment failure during GDC embolization of cerebral aneurysms.
