Objective:
The purpose of this study was to better define the management of intracranial infectious aneurysms.
Methods:
We present a retrospective review of the management of 16 patients with intracranial infectious aneurysms. The mean follow-up period was 86 months.
Results:
None of the patients had a rehemorrhage during antibiotic treatment. The mortality and long-term outcome from ruptured intracranial infectious aneurysms may be better than previously thought. There was no significant difference in long-term outcome between patients with single or multiple infectious aneurysms or between patients who underwent surgical resection and those who were treated only with antibiotics.
Conclusion:
Operative treatment should be pursued for patients with ruptured infectious aneurysms. Patients with unruptured intracranial infectious aneurysms should be observed during antibiotic therapy and followed up with cerebral angiography. Surgical resection should be considered if the aneurysm enlarges and the patient's general medical condition allows general anesthesia to be tolerated.
Insights
Management of intracranial infectious aneurysms can be improved. Ruptured aneurysms require surgery, while unruptured ones benefit from observation and antibiotic therapy, with surgery considered if enlargement occurs.
Area of Science:
- Neurology
- Infectious Diseases
- Neurosurgery
Background:
- Intracranial infectious aneurysms (IIAs) are rare but serious vascular lesions.
- Optimal management strategies for IIAs remain debated.
Observation:
- A retrospective review of 16 patients with IIAs was conducted.
- The mean follow-up period was 86 months.
Findings:
- No rehemorrhage occurred during antibiotic treatment.
- Mortality and long-term outcomes for ruptured IIAs may be better than previously assumed.
- No significant difference in outcomes was observed between single vs. multiple aneurysms or between surgical resection and antibiotic-only treatment.
Implications:
- Ruptured IIAs warrant operative intervention.
- Unruptured IIAs can be managed with observation and antibiotics, with angiography for follow-up.
- Surgical resection for unruptured IIAs should be considered if the aneurysm grows and the patient can tolerate anesthesia.
