An Excellent Functional Recovery Following Grade IV Subarachnoid Hemorrhage From a Cerebral Aneurysm Rebleed With Ultra-Early Surgical Intervention: A Case Report.

Aneurysms are focal abnormal dilations of the arterial wall occurring frequently at branching points along the arteries of the base of the brain. Aneurysmal rupture is one of the possible aneurysm complications and can cause aneurysmal subarachnoid hemorrhages (aSAH). Treatment of aSAH consists of pharmacologic, surgical, or endovascular approaches. The ultra-early intervention of ruptured aSAH occurs within the first 24 hours after ruptured aSAH. This case is about a 49-year-old obese male with multiple comorbidities who suffered from a grade IV subarachnoid hemorrhage and underwent an ultra-early surgical clipping approximately four hours after admission to the emergency center. The patient had excellent functional recovery at a six-month follow-up. Ultra-early surgical intervention for high-grade aSAH with rebleeding could improve outcomes.
