Open Surgery for Recurrent Intracranial Aneurysms: Techniques and Long-Term Outcomes

Area of Science:

• Neurosurgery
• Vascular Surgery
• Cerebrovascular Disease

Background:

• Aneurysm occlusion can lead to regrowth or new aneurysm formation.
• Recurrent aneurysms pose a significant clinical challenge.
• Long-term outcomes of microsurgical treatment for recurrent aneurysms require detailed analysis.

Purpose of the Study:

• To present the experience and analyze long-term results of microsurgery for recurrent aneurysms.
• To evaluate the safety and efficacy of various microsurgical techniques in managing aneurysm recurrence.

Main Methods:

• Retrospective analysis of 44 patients undergoing recurrent aneurysm clipping by senior authors.
• Surgical techniques included clipping, bypass, trapping, and proximal occlusion.
• Outcomes were assessed using the modified Rankin Scale.

Main Results:

• The study included 44 patients (23% male, 77% female) with a mean age of 63 years.
• Treatment modalities varied, with clipping (43%) and aneurysm trapping with bypass (23%) being most common.
• A favorable outcome (modified Rankin Scale 0-1) was observed in 84% of patients at a mean follow-up of 3.5 years.

Conclusions:

• Microsurgery for recurrent aneurysms is a safe and effective treatment option.
• A high rate of favorable outcomes supports the continued use of microsurgical techniques.
• Long-term follow-up demonstrates the lasting benefits of these interventions.
