We report the histopathologic examination of Wingspan stent in acute ischemic stroke.
A 75-year-old female presented with acute left-hemiplegia due to right carotid terminus occlusion. Mechanical embolectomy was unsuccessful.
A Wingspan stent was placed from the distal intracranial carotid artery to the proximal middle cerebral artery stem and established partial antegrade flow. The patient died of malignant infarction on post-stroke day 7. At autopsy, embolized calcified atherosclerotic plaque fragments were noted within a non-occlusive thrombus over which the Wingspan stent was deployed. There was no evidence of intimal or media dissection or perforator ostium occlusion.
Our case provides a rare pathological description of intracranial stent placement in the setting of acute ischemic stroke.
我们报告 Wingspan 支架在急性缺血性脑卒中中的组织病理学检查结果。
一名 75 岁女性因右侧颈内动脉终末段闭塞导致急性左侧偏瘫。机械取栓术不成功。
从远端颈内动脉到近端大脑中动脉主干放置了 Wingspan 支架，建立了部分顺行血流。患者在卒中后第 7 天死于恶性梗死。尸检时，在 Wingspan 支架放置的非闭塞性血栓上发现了栓塞的钙化粥样硬化斑块碎片。没有内膜或中膜夹层或穿支口闭塞的证据。
我们的病例提供了急性缺血性脑卒中时颅内支架置入的罕见病理描述。
