A '''Guglielmi Detachable Coil''', or '''GDC''', is a [[platinum]] coil commonly used in intracranial [[non-invasive surgery]] for the occlusion of brain [[cerebral aneurysm|aneurysms]]. It was invented by Italian interventional neuroradiologist Dr. Guido Guglielmi in [[1990]], and was gradually introduced in the later [[1990s]] as an alternative to surgical [[clipping]], which requires invasive surgery. |
|||
The peculiarities of this coil lie in its physical as well as its [[electrolysis|electrolytical]] properties: The material has a high [[memory effect]], allowing it to easily bend and regain its original coil shape. It is also highly sensitive to low currents, which allow the GDC to detach from the [[catheter]] that carries it, thus receiving the name of "detachable coil". |
|||
The long-term efficacy of GDC coils and similar coils in the treatment of [[cerebral aneurysm|cerebral aneurysms]] is still being studied, and is discussed in further detail [[cerebral aneurysm|here]] |
