Endovascular Treatment of Complex Cerebral Aneurysms A 14-Year Review of Coiling Techniques

Introduction

Cerebral arterial saccular aneurysms, particularly complex ones, present a significant challenge in neurosurgical treatment. A comprehensive 14-year study conducted at the Scientific-Practical Center of Endovascular Neuroradiology (Ukraine) analyzed different endovascular coiling techniques to evaluate their efficacy, safety, and long-term outcomes. This blog explores key insights from the study, offering a practical understanding of treatment effectiveness across three distinct endovascular methods.

Study Overview and Methodology

Researchers reviewed data from 1,345 patients treated between 2002 and 2016. Of those, 214 patients were selected for long-term observation and divided into three groups based on the endovascular technique used:

• Group I: Mono-coils occlusion (82 patients)
• Group II: Balloon-remodeling technique (68 patients)
• Group III: Stent-assisting technique (64 patients)

Patients were evaluated based on the Glasgow Outcome Scale (GOS), Modified Rankine Scale (mRS), and Modified Raymond-Roy Scale (MRRS) for occlusion effectiveness.

Key Findings

• Effectiveness Across Groups:
  • Effective occlusion was observed in:
    • Group I: 76.8%
    • Group II: 75%
    • Group III: 68.7%
  • No statistically significant differences were found in primary occlusion or complications across groups.
• Long-term Stability:
  • Balloon-remodeling showed the lowest recanalization rate (9.7%) and highest occlusion stability.
  • Stent-assisting led to occlusion improvement in 36.4% of patients.
  • Mono-coils had the highest recanalization rate (42.9%) over 2-3 years.
• Complications:
  • All techniques demonstrated low and statistically comparable complication rates.
  • Most patients across all groups had good outcomes on the GOS and mRS scales.

Clinical Implications and Broader Context

This study reinforces the role of individualized treatment based on aneurysm complexity criteria. By using tailored approachesespecially balloon and stent-assisted methods clinicians can achieve better long-term stability and patient outcomes.

The American Stroke Association (ASA) highlights that timely intervention and aneurysm-specific treatment plans are crucial in reducing mortality from subarachnoid hemorrhages caused by aneurysm rupture.

Practical Takeaways

• Balloon-remodeling offers the best long-term stability.
• Stent-assisting improves outcomes post-procedure.
• Mono-coils may be suitable in acute settings but have higher recanalization risk.
