Despite study results showing that it is not cost-effective to screen for asymp-tomatic UIA [2], such screening has become widespread, and UIA is being identified with increasing frequency. Patients with UIA always have risks of rupture with intracranial aneurysms. A nationwide study in Sweden often treated to prevent SAH, and these prophylactic treatments include neurosurgical clipping and endovas-cular coiling. Neurosurgical clipping of the aneurysm was the standard treatment prior to the introduction of detachable coils, but endovascular coiling has recently been increasing [4]. Neurosurgical clipping is recom-mended over endovascular coiling for young patients and for small or anterior circulation aneurysms, i.e., low-risk cases [5]. Neurosurgical clipping is an order of mag-nitude more durable than endovascular coiling, but endovascular coiling is less invasive than neurosurgical * Correspondence
