Endovascularembolization treatment of intracranial aneurysms

：Objective To evaluatethe effect ofendovascular embolization on intracranial aneurysms with detachable coil anddetachable balloon and to emphasize the mainpoint of embolization technique.Methods 1328patients underwent complete cerebral angiography using microcatheter under DSA imaging. 85cases with 90 aneurysms were embolized by MDS, 825 cases with 847 aneurysms were embolizedby GDC, 418 cases with 433 aneurysms were embolized by EDC. 37 of 67 giant aneurysms wereembolized 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 recoveredclinically, 6 patients died. 1 281 aneurysms achieved 100 % occlusion, 65with 95 %occlusion, 20 with 90 % occlusion, and 4with 80 % embolization. 9 aneurysms reputuredduring the embolization, 5 patients had cerebral infarction, 1 patient died of intractablecerebral vasospasm for microcoil escape. 2 recurrent cases were cured by second GDCembolization. Conclusion The method of endovascular embolization to treat intracranialaneurysm is safe, reliable and effective. Those cases with giant aneurysms will have highrecurrence. Patients who suffer from SAH repeatedly may have great possibility of aneurysmrupture during embolization. Key words: Cerebral aneurysm;  Embolization, therapeutic;  Radiology,interventional
