Purpose:
To evaluate endovascular treatment of saccular intracranial aneurysms with mechanical detachable spiral coils.
Materials And Methods:
Fifty-three patients with 56 saccular aneurysms underwent endovascular treatment with spiral coils. All but five had symptomatic subarachnoid hemorrhage staged according to the Hunt and Hess classification as follows: stage IV or V (n = 20), stage III (n = 10), stage I or II (n = 20), and stage 0 (asymptomatic [n = 6]).
Results:
Forty-seven aneurysms were occluded (100% occlusion) on follow-up angiograms with the following time distribution: 24 months for six aneurysms (six patients), 12 months for 14 aneurysms (11 patients), 6 months for 13 aneurysms (13 patients), 4 months for four aneurysms (four patients), and only immediate postprocedure study for 16 aneurysms (16 patients) (excludes two deaths and one failure).
Conclusion:
In this relatively small group, endovascular treatment with mechanical detachable spiral coils had a success rate of 90%, and it appears to be a rapid, reliable, and relatively safe technique in the treatment of life-threatening subarachnoid hemorrhage.
