Abstract:

Objective To assess the features of the cortical and medullary veins on the susceptibility weighted imaging(SWI) in patients with hyperacute and acute ischemic stroke and its relationship with stroke severity and the anatomical characteristics of the infarctions to provide the clinical diagnosis information and treatment related reference and guidance for patients with stroke.    Methods    We selected 38 stroke patients hyperacute ischemic and 62 patients with acute ischemic stroke. The examinations were conducted using MRI. The stroke severity and anatomy of infracts were assessed. Results The NIHSS score was 8(4~8.8)in PAVS(+) and 5.5(3~8)in PAVS(-) for hyperacute ischemic stroke (P=0.058). The NIHSS score was 5 (2~7) in PAVS(+) and 1.5 (1~2) in PAVS(-) for acute stroke (P=0.043). The frequency of PAVS was 82.8% in the anterior circulation ischemic stroke and 28.6% in the posterior circulation ischemic stroke (P<0.001).   Conclusion The appearance of PAVS represents poorer stroke severity in the acute ischemic stroke, except for the hyperacute ischemic stroke. The anterior circulation acute stroke tends to represent PAVS.
