Background Perihematomal edema (PHE) is an important determinant of outcome in spontaneous intracerebral hemorrhage (ICH) due to cerebral small vessel disease (CSVD). However, it is not known to date whether the severity of CSVD is associated with the extent of PHE progression in the acute phase. Purpose To investigate the association between the magnetic resonance imaging (MRI) marker of severe chronic‐ischemia cerebral small vessel changes (sciSVC) and PHE growth or hematoma absorption among ICH patients with hypertension. Study Type Retrospective. Population Three hundred and sixty‐eight consecutive hypertensive ICH patients without surgical treatment. Field Strength/Sequence 3 T; spin‐echo echo‐planar imaging‐diffusion‐weighted imaging (DWI); T2‐weighted, fluid‐attenuated inversion recovery (FLAIR), T2*‐weighted gradient‐recalled echo and T1‐weighted. Assessment The hematoma and PHE volumes at 24 hours and 5 days after symptom onset were measured in 121 patients with spontaneous ICH who had been administered standard medical treatment. Patients were grouped into two categories: those with sciSVC and those without. The imaging marker of sciSVC was defined as white matter hyperintensities (WMHs) Fazekas 2–3 combined cavitating lacunes. Statistical Tests Univariable analyses, χ2 test, Mann–Whitney U test, and multiple linear regression. Results The presence of sciSVC (multiple lacunes and confluent WMH) had a significant negative influence on PHE progress (Beta = −5.3 mL, 95% CI = −10.3 mL to −0.3 mL), and hematoma absorption (Beta = −3.2 mL, 95% CI = −5.9 mL to −0.4 mL) compared to that observed in the absence of sciSVC, as determined by multivariate linear regression analysis. Data Conclusions The presence of sciSVC (multiple lacunes and confluent WMH) negatively influenced hematoma absorption and PHE progress in ICH patients. Level of Evidence 4 Technical Efficacy Stage 3
