Clinical and Radiologic Results of Endovascular Coil Embolization for Cerebral Aneurysm in Young Patients

PURPOSE: This study is an overview of the clinical and radiologic outcomes of endovascular coil embolization for cerebral aneurysm in patients aged 40 years and younger. MATERIALS AND METHODS: Between January 2008 and June 2011, 218 aneurysms were treated using endovascular coil embolization and followed up with cerebral angiography at least six months later. Twenty-one aneurysms occurred in patients aged 40 years and younger, while 197 occurred in 179 patients older than 40 years. The clinical and radiologic results were retrospectively analyzed and compared between the two groups using the modified Rankin scale scores and the modified Raymond scale. RESULTS: Follow-up cerebral angiography revealed two (9.5%) major and two (9.5%) minor recanalized aneurysms in patients aged 40 years and younger, and six (3.0%) major and 35 (17.7%) minor recanalized aneurysms in patients older than 40 years. However, the differences between the groups were not statistically significant. The preoperative and postoperative mean modified Rankin scale scores at time for follow-up angiography were 1.14 and 0.19 respectively for patients aged 40 years and younger, and 1.30 and 0.30 respectively for patients older than 40 years. CONCLUSION: The younger patients had clinically favorable outcomes with tolerable angiographic follow-up results. More regular and long-term imaging follow-up is required for younger patients due to their longer life expectancy.
