Has a fast treatment transition from surgical to endovascular operations improved the survival of aneurysmal subarachnoid hemorrhage?

ABSTRACT:

Background

Several studies have attributed decreasing case fatality rates (CFRs) of aneurysmal subarachnoid hemorrhage (aSAH) to the gradually increasing use of endovascular treatment without considering improvements in other outcome-affecting factors. To assess the independent effect of a treatment modality on CFRs, we investigated CFR changes in a high-volume center rapidly transitioning from surgical to endovascular operations as the first-line treatment for all aSAH patients except those with middle cerebral artery (MCA) aneurysms.

Methods

We identified all surgically/endovascularly treated aSAH patients in Helsinki University Hospital (HUH) during 2012-2017. As the treatment shift occurred in 2015, we defined two treatment eras: surgical (2012-2014) and endovascular (20
