Clipping and Coiling of Unruptured Intracranial Aneurysms Among Medicare Beneficiaries, 2000 to 2010.

ABSTRACT:

Background and purpose

Endovascular coiling therapy is increasingly popular for obliteration of unruptured intracranial aneurysms, but older patients face higher procedural risks and shorter periods during which an untreated aneurysm may rupture causing subarachnoid hemorrhage (SAH). We assessed trends in clipping and coiling of unruptured intracranial aneurysms, outcomes after clipping and coiling of unruptured intracranial aneurysms, and in SAH among Medicare beneficiaries.

Methods

Using 2000 to 2010 Medicare Provider Analysis and Review data, we identified 2 cohorts of patients admitted electively for clipping or coiling of an unruptured aneurysm: (1) utilization cohort (2000-2010): patients ≥65 years enrolled ≥1 month in a given year and (2) outcomes cohort (2001-2010):
