One of the major complications of subarachnoid hemorrhage (SAH) is vasospasm which could last days. This could affect the clearance of interstitial fluid (ISF) from the brain parenchyma by restricting its movement along the intramural periarterial drainage (IPAD) pathway. This would result in dilated perivascular spaces (PVS) which have been shown to be an MR biomarker of failure of IPAD. We explore the hypothesis that patients with hemorrhage will present with an increased prevalence of PVS at six months.
