| Abstract |
Objective
To analyze the incidence and risk factors for symptomatic ischemic complication and microemboli detected as MR diffusion-weighted
imaging (MR-DWI) positive lesions after coil embolization of unruptured intracranial aneurysm in the elderly patients aged over 65 years.
Methods
Between January 2008 and December 2011, unruptured intracranial aneurysms in 51 patients underwent coil embolization and
post-treatment MR-DWI. The incidence of MR-DWI positive lesions and symptomatic ischemic complications were analyzed. Risk factors for
DWI positive lesions were analyzed by the category of aneurysm size, aspect ratio, total procedure time, and the present use of stent.
Results
The incidence of DWI positive lesion and symptomatic ischemic complication was 66.7% and 7.8%, respectively. Compared to MR-DWI
negative group, MR-DWI positive groups tent to show larger size of aneurysm, lower aspect ratio, longer treatment time, and more use
of stent respectively, but all did not show statistical significance.
Conclusion
When compared with the general population, the elderly showed a relatively high incidence of microemboli and symptomatic
ischemic complications after coil embolization of unruptured intracranial aneurysm. Detailed evaluation and careful treatment should be made
during coil embolization in elderly patients. |
