摘要: Background and Purpose— The purpose of this study was to assess the effect postcontrast CT (PCCT) leakage (PCL) on hematoma growth in CTA spot negative patients. Methods— A retrospective 61 patients presenting within 6 hours primary ICH onset imaged with angiography (CTA) PCCT. Presence sign PCL were documented. defined as presence contrast extravasation PCCT at a location remote from if present. Hematoma expansion >6 mL or 30% enlargement. Patients dichotomized by compared for baseline demographic data, size, using unpaired t test Mann-Whitney continuous categorical respectively. probability value <0.05 considered significant. Results— present 11/61 (18%), occurring 5 without (45%). Spot demonstrated larger absolute (P=0.02) percentage gr...
