|Perfusional defects on CTP for the early detection of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrage (aSAH).|
Methods and materials
We included 415 consecutive patients with symptomatic aSAH (mean age 61,8y, april 2009-september 2017), who underwent NCCT/CTP/CTA for imaging and subsequent endovascular treatment with permanent exclusion. Clinical deterioration after aSAH were categorized into DCI and no DCI. CTP maps were automatically calculated tracer delay-sensitive algorithms and were also visually assessed for the presence of perfusional defects by two independent experienced readers. Age, sex, comorbidity, Hunt-Hess score at presentation, outcome (mRS<2), vasospasm evaluated with TICI and CTP were correlated using a multiple logistic regression analysis (p<0.005).
