Objective To investigate the
safety and
efficacy of endovascular
treatment of distal
middle cerebral artery aneurysms.
Methods From January 2009 to December 2016,the
medical records of 13 consecutive
patients with distal
middle cerebral artery aneurysm (a total of 14
aneurysms)were reviewed and enrolled. Endovascular
treatment included coils,coils with liquid embolic materials,or using liquid embolic material alone for embolization of
aneurysms or occlusion of
parent arteries. The immediate outcome of
aneurysm treatment was evaluated by Raymond
classification,and the clinical
prognosis was evaluated by the modified Rankin scale (mRS). DSA was use to conduct imaging
follow-up study and was compared with the immediate
treatment outcome in order to determine whether the
aneurysms recurred or not. Results Of the 13
patients,8 were
males,with an average age of 40 ±14 years. The maximum diameter of
aneurysm was 1. 0 -12. 0 mm,the median size was 4. 5 mm. Fourteen
aneurysms were successfully treated by endovascular
treatment,4 of them were embolized,and the
parent aneurysms were retained;10
aneurysms and
parent arteries were occluded. Twelve
aneurysms did not develop immediately after operation,and 2 of them had residual
aneurysms. No new nerve dysfunction and related
complications were found after endovascular
treatment. The clinical follow-up period was 9 -96 months,and the median
time was 30. 9 months. Twelve
aneurysms were followed up for 6 -24 months with a median
time of 15. 2 months. No
recurrence of
aneurysms were observed. Conclusions Using endovascular
treatment technology for the
treatment of distal
middle cerebral artery aneurysms is safe and effective. It can be considered in the development of
treatment programs.
