Unruptured cerebral aneurysm clipping: association of combined open and endovascular expertise with outcomes.

ABSTRACT:

Background

It is often questioned if one physician can conduct both open and endovascular techniques successfully and safely.

Objective

To investigate the association of combined open and endovascular expertise with the outcomes of unruptured cerebral aneurysm clipping.

Methods

We performed a cohort study of 100% of Medicare fee-for-service claims data for elderly patients who underwent surgical clipping for unruptured cerebral aneurysms between 2007 and 2012. To control for confounding we used propensity score conditioning, and controlled for clustering at the physician level.

Results

During the study, 3247 patients underwent clipping for unruptured cerebral aneurysms, and met the inclusion criteria. Of these, 766 (23.6%) underwent treatment by hybrid neurosur
