Techniques and complications in endovascular embolization on acute ruptured intracranial aneurysms with Guglielmi detachable coils

Objective To summarize the techniques and managements of complications in endovascular embolization on acute ruptured intracranial aneurysms with Guglielmi detachable coils (GDC). Methods There were 41 patients with acute ruptured intracranial aneurysms treated with early GDC embolization within 72 hours after the rupture. The diameters of aneurysms ranged from 3.6mm to 25mm. Among them, 39 aneurysms located in the anterior circulation, and 2 in posterior circulation. Results Complete obliteration (100%) was in 33 cases, while 90%-99% in 5 cases and below 90% in 3 cases. The technique-related complications were present in 6 cases, and 5 patients suffered from the complications of SAH. The average hospitalization time was 12 days. No re-rupture occurred in the 12-to-48-month follow-up. 36 patients showed good recovery, 4 patients showed moderate disability and 1 patient died. No patient showed severe disability or was in vegetative state. Conclusion GDC occlusion is a safe and effective treatment for the acute ruptured intracranial aneurysms. Advances in the techniques and treating the complications correctly will decrease the complications and improve future outcomes.
