Coil Embolization in Patients with Recurrent Cerebral Aneurysms Who Previously Underwent Surgical Clipping

Eighth case of our series, basilar tip aneurysm. A, Working angle view angiography before first coil embolization. B, After the first coil embolization, the final angiography evaluation reveals complete occlusion of the aneurysm. C, After 29 months, follow-up angiography reveals major recurrence of the aneurysm. D, After the second coil embolization, the residual neck is detected in the final angiography evaluation. E, Follow-up angiography reveals minor recurrence.

Thirteenth case in our series, left middle cerebral artery bifurcation aneurysm. The first coil embolization of this aneurysm was performed at another hospital. Therefore, we confirmed the presence of a residual neck in the medical record, without imaging. A, At 180 months after the first coil embolization, 3D rotational angiography reveals recurrence of a middle cerebral artery bifurcation aneurysm. B, Working angle angiography before the second coil embolization. C, The final angiography evaluation reveals complete occlusion of the aneurysm.

Fourteenth case of our series, posterior communicating artery aneurysm. A, Working angle view angiography before the first coil embolization. B, After the first coil embolization, the final angiography evaluation reveals the residual neck of the aneurysm. C, After 18 months, follow-up angiography reveals major recurrence of the aneurysm. D, After the second coil embolization, a residual neck is detected in the final angiography evaluation. E, Follow-up angiography reveals minor recurrence.
