Abstract: Objective: To investigate the clinical value of endovascular coil embolism of intracranial aneurysm and discuss the points for attention during the procedure.Methods: Twenty patients with intracranial aneurysms were undergone the embolism with intravascular coils.In the study,2 cases who had wide-neck aneurysms were treatment with neuroform stent placement.All cases were diagnosed by digital subtraction angiography (DSA) before operation.Results: Nineteen cases were successfully for the therapeutic processes,while 1 was ruptured during operation and died within 4 days;1 was complicated the blockage in the right PCA after operation 3 days and died in the next two days.Fifteen cases were followed up for 6-8 months by DSA,the aneurysms were embolizated completely and the parent artery was patency.Conclusions: Endovascular coil embolization of intracranial aneurysms is a safe and effective method.Several techniques combination will improve future outcomes according to the shape of aneurysms.
