In this study, we quantitatively measured vascular diameter changes during the vasospasm period at various vascular sites to investigate the association between the radiological and clinical effects of clazosentan.Materials and MethodsWe retrospectively analyzed 22 patients with aSAH classified as Fisher group 3, treated at our hospital. Clazosentan (10 mg/h) was administered to 12 patients, while 10 patients received conventional vasospasm management. Arterial diameters at 12 locations were measured at the onset and during the vasospasm period. Quantitative changes in vascular diameter were compared between the clazosentan and nonclazosentan groups.ResultsDuring the vasospasm period, mean arterial diameters increased in all regions, including the posterior circulation, except internal carotid artery (ICA) top in the clazosentan group, while they decreased across all regions in the nonclazosentan group (overall average: + 22.3% vs. -16.9%; <i>p</i> = 0.005).

However, its limited effect on proximal arteries suggests a need for supplementary treatments targeting these regions to improve clinical outcomes.
