Data Collection
Data was collected from either a preexisting database of adult ECMO patients, where available, or directly from patient charts. Baseline demographic information, including age, gender, body mass index, comorbidities, and etiology of cardiogenic shock was recorded for all patients. Characteristics of ECMO support in each patient were also collected. Each head CT imaging was reviewed by a single board certified vascular neurologist (JW) to determine the type and location of stroke.
