Mechanical detachable coil as a therapeutic alternative for cerebral aneurysm.

Endovascular treatment for unruptured cerebral aneurysms has been recognized as a useful alternative. Various types of intravascular materials embolizing aneurysms were classified into one of two groups. One was retrievable after the placement, whereas the other was irretrievable. The former which has involved detachable coils is preferred, because it can be repositioned repeatedly, while it forms the most effective arrangement. In this report, we present a compromised patient who was a 68 year-old female suffering angina pectoris and was treated with an interlocking detachable coil. Technical points are discussed here compared with Guglielmi's detachable coil.
