Coil Embolization of Residual or Recurrent Aneurysms after Craniotomy

Purpose : Intracranial residual or recurrent aneurysms can occur after surgical clipping, with risks of growth and rupture. And the treatment of residual or recurrent aneurysms have higher risk than the initial operation. We present treatment of five residual or recurrent aneurysms after craniotomy with Guglielmi detachable coil (GDC). Material and Methods : From 1996 to 2006, we treated five residual and recurrent previously clipped and wrapped aneurysms with GDC. One patient was after wrapping, two patients were residual aneurysms, and another two patients were recurrent aneurysms. Results : The endovascular approach was successful in all patients and the control angiogram shows complete obliteration in one aneurysm and small neck remnant in four patients. There was no complication of treatment. Conclusion : Coil embolization is a good treatment option for patients with residual or recurrent aneurysms after clipping or wrapping surgery
