Blood Pressure and Spot Sign in Spontaneous Supratentorial Subcortical Intracerebral Hemorrhage

Abstract: Background Spontaneous intracerebral hemorrhage is a potentially devastating cause of brain injury, often occurring secondary to hypertension. Contrast extravasation on computed tomography angiography (CTA), known as the spot sign, has been shown to predict hematoma expansion and worse outcomes. Although hypertension has been associated with an increased rate of the spot sign being present, the relationship between spot sign and blood pressure has not been fully explored. … Show more

“…The study’s robustness would have been greatly improved if ambulatory BP monitoring had been utilized. Fourthly, the associations between BP and imaging features of early HE, such as the CT island sign and CT angiographic spot sign, were not analyzed, as previous similar studies had already covered this topic ( 33 ). Finally, despite our study finding a notable link between pulse pressure and early HE, the precise mechanism driving this correlation is still not fully understood.…”
