Cerebral mycotic aneurysms treated with a neuroform stent: technical case report.
OBJECTIVE
We describe the first documented endovascular treatment of proximal intracranial mycotic aneurysms by a self-expanding, flexible, dedicated, intracranial Neuroform stent. Treatment with this stent rapidly obliterated the aneurysms, eliminated the need for additional coiling, and maintained the patency of the parent arteries.


METHODS
A 47-year-old male patient with infective endocarditis presented with ischemic stroke and minimal subarachnoid hemorrhage. Cerebral angiography demonstrated a fusiform aneurysm of the supraclinoid segment of the left internal carotid artery and horizontal segment of the left middle cerebral artery, with superimposing side-wall focal aneurysms. Despite antibiotic therapy, the focal aneurysms progressively enlarged, as demonstrated on a subsequent cerebral angiogram at Day 11.


METHODS
A 4-mm x 2-cm Neuroform stent was deployed along the fusiform aneurysm of the left supraclinoid internal carotid artery and the horizontal middle cerebral artery M-1 segment encompassing the focal side-wall aneurysms with preserved patency of the parent arterial segments.


CONCLUSIONS
Endovascular stent placement can be an effective treatment for proximal intracranial mycotic aneurysms that fail to respond to medical therapy.
