PURPOSE: We present a series of patients with subarachnoid hemorrhage (SAH) from ruptured intracranial aneurysms who were treated with endovascular embolization by detachable coils. MATERIALS AND METHODS: There were 108 patients with SAH treated with endovascular coiling. The efficacy of the endovascular coiling was estimated by initial postembolization angiography and by digital subtraction angiography after 6 months, using the following categories: complete occlusion of an aneurysm (98%-100%), near-complete occlusion (90%-98%), and incomplete occlusion (<90%). RESULTS: In 42 (39%) patients the endovascular coiling was performed during the fi rst 72 h after SAH, and 48 (44%) patients had aneurysms <10 mm in diameter. The most frequent location of ruptured aneurysms was the internal carotid artery (39 patients, 36%). Initially, complete occlusion of the aneurysm was achieved in 87 patients (81%), near-complete in 12 patients (11%), and incomplete in 9 patients (8%). After 6 months, complete occlusion of the aneurysm remained in 84 patients, near-complete in 12 patients, and incomplete in 6 patients; 6 patients were lost to follow-up. CONCLUSION: Endovascular coiling of ruptured intracranial aneurysms is an efficient procedure that should be performed as soon as possible after detection of an SAH.
