dc.description.abstractPurpose: This study aimed to investigate whether enlarged perivascular spaces (ePVS) within the basal ganglia (BG) or centrum semiovale (CSO) aggravate in patients with aneurysmal subarachnoid hemorrhage (aSAH). Methods: We retrospectively evaluated 139 patients who had undergone brain magnetic resonance imaging (MRI) within 1 month of aSAH occurrence from January 2007 to November 2018. Follow-up brain MRI of 99 patients were available. We scored ePVS in the BG and CSO on a score of 0-4 (0 = no ePVS, 4 ≥ 40 ePVS) on initial and follow-up T2-weighted MRI. Aggravation of ePVS was defined as an ePVS score increase of ≥ 1 on follow-up MRI compared to the initial score. We compared the characteristics between patients with and without aggravation of ePVS and investigated associated variables using logistic regression. Results: Aggravation of ePVS in the CSO and BG was noted in 31 (31.3%) and 6 (6.1%) patients, respectively. After adjusting for age, sex, and the MRI follow-up period, aggravation of ePVS in the CSO was independently associated with a high Fisher grade (p = 0.007) and high burden of initial ePVS in the CSO (p = 0.049). Conclusion: Aggravation of ePVS, particularly those in the CSO, had occurred in the long-term follow-up of aSAH patients. This was independently associated with a high burden of aSAH. The amount of subarachnoid blood might have aggravated the drainage of interstitial fluid through glymphatic dysfunction.-
