Abstract

Spontaneous calcific embolism is an uncommon cause of stroke. In most cases calcified cardiac valves are the sources of the emboli although embolization of calcific material from the brachiocephalic trunk has also been described. We report a case of stroke attributable to spontaneous calcific emboli from the aortic arch in which migration of the emboli was observed along the middle cerebral artery following iv tPA.

摘要

自发性钙化栓塞是一种罕见的中风病因。在大多数情况下，钙化的心脏瓣膜是栓子的来源，尽管也有来自头臂干的钙化物质栓塞的报道。我们报告一例由主动脉弓自发性钙化栓子引起的中风病例，在静脉注射组织型纤溶酶原激活剂（tPA）后，观察到栓子沿大脑中动脉移动。
