摘要
目的探讨急性双侧对称性脑梗死的发病机制。方法回顾性总结19例单纯位于幕上或幕下的急性双侧对称性脑梗死患者的临床及影像学资料,结合改良TOAST分型,探讨其可能的发病机制。结果急性双侧对称性脑梗死常见部位有胼胝体、分水岭区、丘脑、脑叶、脑干和小脑;其危险因素与一般脑梗死相同,部分患者可有血流动力学异常的诱因;发病机制包括血栓形成、心源性或动脉源性栓塞、低灌注、穿支动脉病以及多重发病机制的相互作用,分水岭区的双侧梗死常与低灌注有关,胼胝体、丘脑、脑干、小脑的双侧梗死应考虑到血管解剖变异存在的可能。结论急性双侧对称性梗死的发病机制复杂,相关发病危险因素或诱因、梗死灶分布以及血管检查可为探讨其发病机制提供参考依据。
