Neck Clipping of Previously Clipped, Recurrent Intracranial Aneurysms: Removal of the Previous Clip for Full Exposure of the Aneurysm and Sparing of Perforating Arteries

Abstract

Neck clipping is a well-established treatment for intracranial aneurysms. After neck clipping, there is a low, but considerable, risk of aneurysm recurrence. Treatment of previously clipped, recurrent aneurysms is one of the most difficult procedures in aneurysm surgery. Sharp dissection around the aneurysm is essential, and the previous clip must be removed to ensure complete obliteration of the aneurysm and to spare the perforating arteries.
