Coil embolization of brain aneurysms is a well-established alternative to surgery and the first choice treatment in many cases. However, the embolization of giant aneurysms (maximum diameter >10 mm) and wide-necked lesions (maximum neck diameter > 4 mm or a dome/neck ratio < 2) carries a high risk of coil migration. This complication increases the risk of thromboembolism. Endovascular techniques commonly used to treat giant and widenecked aneurysms include remodelling, embolization with three-dimensional coils and the combined use of intracranial stents with coils or Onyx. We report our experience of stenting associated with coil embolization to treat wide-necked aneurysms.

Abstract
Coil embolization of brain aneurysms is a well-established alternative to surgery and the first choice treatment in many cases. However, the embolization of giant aneurysms (maximum diameter >10 mm) and wide-necked lesions (maximum neck diameter > 4 mm or a dome/neck ratio < 2) carries a high risk of coil migration. This complication increases the risk of thromboembolism. Endovascular techniques commonly used to treat giant and widenecked aneurysms include remodelling, embolization with three-dimensional coils and the combined use of intracranial stents with coils or Onyx. We report our experience of stenting associated with coil embolization to treat wide-necked aneurysms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
