Repeated Endovascular Coil Occlusion in 350 of 2759 Intracranial Aneurysms: Safety and Effectiveness Aspects

Abstract

The natural course of aneurysm remnants or recurrent aneurysm perfusion after coil treatment is not completely understood. The low risk of bleeding from partially filled aneurysms must be balanced against the procedure-related risks of retreatment. Great caution is recommended for the treatment of asymptomatic recurrent aneurysms.
