The safe and accurate opening of the sylvian fissure is desirable for a good prognosis. Methods: The aim of this report is to demonstrate the use of indocyanine green (ICG) videoangiography to recognize the superficial sylvian vein (SSV) and thus enable a wide opening of the sylvian fissure, especially in patients with subarachnoid hemorrhage (SAH). Results: The small tributary flowing into the SSV was distinguishable from a passing one, which deeply entered the insula. In addition, an entering point of a tributary to the SSV, which ran perpendicular to the insula, was occasionally determined. SSV, which was barely discernable in a reddish SAH involving the sylvian fissure, was clearly demarcated using ICG videoangiography. Two representative cases of sylvian dissection are herein presented. Conclusion: The performance of ICG videoangiography before sylvian dissection is a simple and useful method for identifying a vital approach route for safe and accurate sylvian dissection, and it reduces the risk of causing any accidental injury to the veins in the sylvian fissure.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/b9838e96-8b30-4193-917a-e9cfc8217f66/featured/hero-1782420812347.png","publishDate":"2016-06-03T00:00:00.000Z","doi":"10.4103/2152-7806.183526","categories":["Cerebrovascular","Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/b9838e96-8b30-4193-917a-e9cfc8217f66/pdf"}
