Endovascular management of a giant aneurysm through saphenous vein graft after extracranial-intracranial bypass: case report and literature review.

It is known that giant intracerebral aneurysms have a high rupture and mortality rate. Furthermore, their optimal treatment method is not straightforward. While traditionally they have been managed with surgical clipping, it is not always possible. A unique case is presented in which a patient with multiple intracranial aneurysms was treated using a multimodality approach. After an intracranial-extracranial bypass, the left internal carotid artery ophthalmic aneurysm continued to grow on follow-up angiogram. Thus it was decided to go ahead with coiling of the aneurysm. The coils were delivered through the saphenous vein graft. The patient tolerated the procedure well and there were no procedural complications.
