Identifying Posterior Circulation Candidates for Thrombectomy Using Perfusion Imaging
Rochester, MN
The purpose of this study is to determine if cerebral perfusion imaging can identify a subset of patients who are most likely to have a favorable outcome after thrombectomy treatment. We hypothesize that patients with a favorable Critical Area Perfusion Score (CAPS≤3) on cerebral perfusion imaging will have a favorable response to revascularization by thrombectomy and that patients with a CAPS>3 will not.

A Study of the Effects of Cytochrome P450 Enzyme on the Metabolism of Nimodipine after Aneurysm
Jacksonville, FL
The purpose of this study is to determine if cytochrome P450 (CYP) enzyme family variants alter the body's metabolism of nimodipine after Aneurysmal Subarachnoid Hemorrhage (aSAH), and if actual levels of nimodipine correlate with clinical events and patient outcomes.
