Background
Infectious intracranial aneurysms (IIAs) are rare but can cause substantial morbidity
and mortality. We aimed to re-evaluate the role of endovascular therapy for the treatment
of IIAs.
Methods
This study is a retrospective review of patients diagnosed with IIAs and treated by
endovascular therapy in our institutions over the past 13 years.
Results
Four patients were diagnosed with infectious endocarditis with a total of 5 IIAs.
Three of the 4 patients had ruptured IIAs. Two presented with intracerebral hemorrhage,
one with subarachnoid hemorrhage, and one with cerebral infarction. The distal middle
cerebral artery (MCA) was the most common site, followed by the distal segment of
the posterior cerebral artery. Three patients were treated by parent artery occlusion
and one by direct aneurysm obliteration. There were no periprocedural complications.
One IIA treated by direct aneurysm occlusion was recanalized within 1 year and required
a second embolization. Outcomes were measured by the modified Rankin Scale on discharge:
2 patients scored 0, 1 patient scored 1, and 1 patient scored 3.
Conclusion
IIAs located deep in the brain or on the peripheral MCA can be safely treated with
endovascular therapy even when they are lying in the eloquent cortex.
