A narrative review in managing ICA aneurysms

Introduction: Internal carotid aneurysms are among the most common intracranial aneurysms, with nearly 20-25% of the ruptured aneurysms patients succumbing to death before reaching hospital. Most aneurysms are discovered in the context of an SAH, unruptured aneurysms can also be detected in patients presenting with other clinical symptoms or incidentally through neuroimaging. Materials and methods: We searched Google and indexed articles with the keywords “ICA aneurysm management". We took 45 articles to identify epidemiology, diagnosis and management of these aneurysms. Both microscopic and endovascular treatments were taken into account. Results: Clipped aneurysms had a relatively lower percentage of recurrences as compared to endovascular modality, while the incidence of peri-procedural complications was higher with clipping patients. Conclusion: The volume of cases an institution handles influences the procedure's success. Endovascular management of ICA aneurysms has recently gained in numbers compared to open procedures.
