Title : Susceptibility Vessel Sign (SVS) for assessment of Intra arterial thrombus and thrombus burden in patients with acute ischemic stroke: An institutional study


Background and purpose:
SWI can help in the diagnosis of thrombus within the vessel in acute ischemic stroke (AIS) known as susceptibility vessel sign (SVS) and detection of SVS within the vessel can predict treatment modality and outcome. In this study, the purpose is to correlate the SVS on SWI with different parameters of stroke.

It was a retrospective cross-sectional study, where consecutive stroke patients with vessel occlusion on magnetic resonance angiography (MRA) were included for the study for one year. The relation of SVS on SWI with risk factors and territory involved and length of thrombus was correlated with the NIH stroke scale (NIHSS).

A total of one hundred and five patients were enrolled for this study. 62% (66 out of 105) of patients showed SVS on SWI with MRA positive occlusion. A positive correlation was observed between SVS on SWI with the risk factor (p=0.003) with 86% of heart disease and 47% of hypertension had SVS. A positive correlation was also observed between the SVS on SWI with territorial occlusion (p =0.000). There was moderate positive correlation was observed between the NIHSS and thrombus length (p=0.002) with a Pearson coefficient of 0.367.

SWI can be useful in identifying the location of the thrombus, and NIHSS can determine the thrombus length in acute stroke. A higher incidence of SVS can be associated with risk factors and it also depends upon the site of occlusion of the vessel.
