The fresh new hyperdense artery signal (HAS), basic accepted when you look at the 1983, is certainly centered once the an indicator out of acute occlusion by thrombus towards noncontrast CT (NCCT) 52 and is generally on main trunks away from intellectual arteries. 53 , – , 55 Improved sensitiveness to have Possess can be done with thinner incisions, preferably next to step one mm to own max susceptibility unlike traditional 5–ten mm thickness, on account of volume averaging away from intraluminal thrombus and you will close CSF area having thicker slices. 56,57 This new Have was correlated with “very early phase” cystic (RBC prominent otherwise RBC proportion equivalent to fibrin) rather than “late phase” (fibrin principal and you may arranged fibrin), and with cardioembolic etiology. 32,55,58 For the a beneficial meta-study, patients that have Enjoys was likely to has RBC-steeped thrombi. 13

On the one-hand, Keeps is actually of the worse outcomes

The relationship away from Features having outcomes try less obvious. Inside the an analysis of the Ist-step 3 trial, visibility regarding Possess is in the bad result from the six months, and you can outcome is tough with increased detailed Keeps, though it failed to customize the advantage of alteplase. 59 Improved patient result is shown when the Enjoys shrinks or vanishes. 60,e1 Concurrently, several research shows you to definitely higher occurrence out-of thrombi forecasts best recanalization, and you can thrombi which have all the way down thickness had been far more resistant against cures. 31,e2,e3 All the way down blood clots thickness on preintervention CT was a sign regarding lower a reaction to one another tPA and you may EVT.
