Endovascular embolization treatment of intracranial aneurysms / 中华神经医学杂志

ABSTRACT

Objective To evaluate the effect ofendovascular embolization on intracranial aneurysms with detachable coil and detachable balloon and to emphasize the mainpoint of embolization technique.Methods 1328 patients underwent complete cerebral angiography using microcatheter under DSA imaging. 85 cases with 90 aneurysms were embolized by MDS, 825 cases with 847 aneurysms were embolized by GDC, 418 cases with 433 aneurysms were embolized by EDC. 37 of 67 giant aneurysms were embolized by detachable balloon, 18 aneurysms by GDC, 11 aneurysms by EDC, 1 by MDS. Results 1328 patients with 1370 aneurysms were cured successfully; 1 322 cases recovered clinically, 6 patients died. 1 281 aneurysms achieved 100 % occlusion, 65with 95 % occlusion, 20 with 90 % occlusion, and 4with 80 % embolization. 9 aneurysms reputured during the embolization, 5 patients had cerebral infarction, 1 patient died of intractable cerebral vasospasm for microcoil escape. 2 recurrent cases were cured by second GDC embolization. Conclusion The method of endovascular embolization to treat intracranial aneurysm is safe, reliable and effective. Those cases with giant aneurysms will have high recurrence. Patients who suffer from SAH repeatedly may have great possibility of aneurysm rupture during embolization.
