title: [Two cases with coil embolization following incomplete neck clipping].
abstract: We report two cases with embolization (coil embolization) using Guglielumi detachable coils of residual aneurysms following incomplete neck clipping. The first case, a 75-year-old woman suffered from a subarachnoid hemorrhage due to the rupture of a left internal carotid posterior communicating aneurysm in June, 1997. Neck clipping of the aneurysm was performed at day 1. Follow-up angiogram at day 7 showed a residual aneurysm involving the dome of the initial aneurysm. We performed coil embolization of the residual aneurysm following the angiogram. Almost complete obliteration of the aneurysm lasted during the follow-up period of two and a half years. The second case, a 71-year-old woman suffered from a subarachnoid hemorrhage due to the rupture of a right internal carotid posterior communicating aneurysm in May, 1999. Neck clipping of the aneurysm was performed at day 1. Follow-up angiogram at day 7 showed a residual aneurysm involving only a part of the initial aneurysm near the neck. Because no spontaneous thrombosis of the residual aneurysm was obtained after 2 months, we performed coil embolization of the residual aneurysm. Almost complete obliteration of the aneurysm lasted during the follow-up period of 7 months. These patients were discharged with good performance status. We consider the morphologic feature of the residural aneurysm to be most important for determining when to perform coil embolization of such residual aneurysms.
