To describe a case series of patients with cerebrovascular lesions who were treated using an occipital artery (OA) to PCA bypass via the occipital interhemispheric approach. Methods: We retrospectively reviewed three consecutive cases of patients with cerebrovascular lesions who were treated using OA-PCA bypass. Results: OA-PCA bypass was performed via the occipital interhemispheric approach. This procedure included: (1) OA-PCA bypass (n = 1), and combined OA-posterior inferior cerebellar artery and OA-PCA saphenous vein interposition graft bypass (n = 1) in patients with vertebrobasilar ischemia; (2) OA-PCA radial artery interposition graft bypass in one patient with residual PCA aneurysm. Conclusions: OA-PCA bypass represents a useful alternative to conventional STA-SCA or PCA bypass.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/1eadc790-4914-44dc-92e6-510123ca74bb/featured/hero-1782421041596.png","publishDate":"2013-07-12T00:00:00.000Z","doi":"10.4103/2152-7806.114975","categories":["Original Article"],"fullTextUrl":"http://sni.wpengine.com/wp-content/uploads/2015/05/3747/SNI-4-90.pdf"}
