Successful microsurgical clipping of ruptured fusiform aneurysm of the anterior cerebral artery. Case report and review of the literature

BACKGROUND: Fusiform aneurysms (FA) of the anterior cerebral artery (ACA) are found rarely. The common clinical presentation is a subarachnoid hemorrhage (SAH). Surgery is the main treatment to prevent rebleeding. CASE DESCRIPTION: The authors present a case report of the ruptured FA of the ACA. The presented case demonstrates the successful microsurgical clipping of the fusiform ACA aneurysm. CONCLUSION: A1-segment FA can lead to SAH with poor prognosis. The main goal of surgical treatment is to prevent rebleeding. Direct microsurgical clipping is one of the surgical options.
