Abstract

Despite the variable anatomy of the anterior communicating artery AcoA complex three main perforating branches can be typically identified the largest of which being the subcallosal artery ScA We present a case series of infarction in the vascular territory of the ScA to highlight the anatomy the clinical symptomatology and the presumed pathophysiology as it pertains to endovascular and surgical management of vascular pathology in this regionWe identified five different cases of ScA stroke leading to a subsequent infarction of the fornix and the genu of the corpus callosum The presumed pathophysiology in noniatrogenic cases is microangiopathy rather than embolic events iatrogenic SCA occlusion can present after both surgical and endovascular treatment of AcoA aneurysms that may occur with or without occlusion of the AcoAStroke in the vascular territory of the ScA leads to a characteristic imaging and clinical pattern Ischemia involves the anterior columns of the fornix and the genu of the corpus callosum and patients present with a Korsakoff’s syndrome including disturbances of shortterm memory and cognitive changes We conclude that despite its small size the ScA is an important artery to watch out for during surgical or endovascular treatment of AcoA aneurysms
