| Abstract |
Objective
Endovascular treatment of unruptured intracranial aneurysms (UIA) is valuable therapeutic alternative to surgical treatment
of UIA. The purpose of this study was to assess the clinical results of treatments using coil embolization for the UIA.
Methods
Between September 2006 to September 2008, 103 patients harboring 117 unruptured intracranial aneurysms were treated
with endovascular procedure. All procedures were performed under local anesthesia. Several coil systems was used. Additional devices
like the balloon remodeling technique and stents were also occasionally used.
Results
One hundred six (90.6%) unruptured aneurysms were distributed in anterior circulation and 11 (9.4%) was in posterior circulation.
One hundred four (88.9%) aneurysms were smaller than 10 mm in maximum size, 13 (11.1%) aneurysms were 11-20 mm. Complete
embolization was achieved in 95 (81.3%), neck remnants in 16 (13.6%), incomplete embolization in 6 (5.1%), there were 8 procedural
complication, 3 thromboembolization, 3 intraprocedural rupture, 1 transient ICA occlusion, and 1 other. Procedural morbidity and mortality
were 6.6% and 1.7%.
Conclusion
These results indicate that the mortality and morbidity associated with endovascular treatment for unruptured intracranial
aneurysms are favorable. However, further study with a larger study population, procedural complication and long term follow up should
be needed to better define its role in management of such patients. |
