Although these clinical scenarios have traditionally been investigated separately, both are governed by common principles of cerebral venous physiology. This review synthesizes contemporary evidence comparing emergency and elective SSS injury, with particular emphasis on venous reconstruction, postoperative cerebral venous sinus thrombosis (CVST), neurocritical care, and physiology-guided surgical decision-making.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;We conducted a systematic review with narrative synthesis incorporating an umbrella-review component, in which two systematic reviews served as anchor evidence sources and were supplemented by eligible contemporary primary studies.
