CONTRAST EXTRAVASATION ON CT ANGIOGRAPHY PREDICTS HEMATOMA EXPANSION IN INTRACEREBRAL HEMORRHAGE

Background: null null Patients with acute intracerebral hemorrhage (ICH) presenting within 3 hours of symptom onset are known to be at increased risk of expansion. However, only a minority arrive within this time frame. Therefore, alternative markers for expansion risk are needed. null null Objective: null null To examine whether contrast extravasation on CT angiography (CTA) at presentation predicts subsequent hematoma expansion. null null...
