Abstract
Objective To explore the imaging feature of cervical artery dissection (CAD), and analyze the influential factors of prognostic assessed by ultrasound follow-up. Methods From June 2013 to October 2015, inpatients with acute stroke or transient ischemic attack (TIA) following vascular occlusion or stenosis due to CAD admitted to department of neurology, first hospital of Shanxi medical university were consecutively enrolled. All the patients were evaluated by neurovascular ultrasound at 3rd and 6th month respectively after discharge. At 6th month, neurological deficits were assessed using the modified Rankin Scale (mRS). Results Among 42 patients with CAD, 35 cases (83%) were internal carotid artery dissection and the rest of 7 cases (17%) were vertebral artery dissection. 27 cervical artery occlusion cases (64%) were diagnosed by ultrasound, which were all finally confirmed by computed tomography angiography (CTA) or digital subtraction angiography (DSA). The most typical sign of vascular imaging for the cervical artery occlusion was the "dual-chamber sign" (26,63%), followed by "flame sign" (7,17%). There was no significant difference in the proportion of vascular recanalization between good prognosis group and poor prognosis group.The proportion of limb weakness(92.3% vs 45.8%), basal ganglia involvement(69.2% vs 25%)and vertebral artery dissection(100% vs 70.8%)in poor prognosis group were all higher than that in good prognosis group, and the difference was statistically significant. Conclusion The prognosis of cerebral artery dissection is related to limb dysfunction, the position of cerebral infarction, and the type of dissection, but not the recanalization rate.关键词
