Brain aneurysms

What is it about?

Basilar apex brain aneurysms are difficult to reach and located near critical adjacent perforating arteries. As a result, these aneurysms are considered more suitable for treatment by endovascular rather than microsurgical intervention. We compared the immediate and long-term outcomes of microsurgery versus endovascular therapy for this aneurysm subtype. Postoperative complications of cranial nerve deficits and hemiparesis were more common in patients treated microsurgically. However, aneurysm remnants and need for retreatment were more common in the endovascular treatment group. Compared to microsurgical treatment, endovascular management of these aneurysms resulted in higher rates of recurrence and need for retreatment. There were no differences between the two treatment types in rehemorrhage rates and average Glasgow Outcome Score at discharge and 1 year after treatment.
