Large fusiform aneurysms in the distal anterior cerebral territory are infrequent and pose considerable treatment challenges, as they necessitate comprehensive aneurysm resolution without compromising physiological flow dynamics. 1-3 We present the case of a 52-year-old man with a ruptured distal anterior cerebral artery fusiform aneurysm. The patient consented to the procedure; this complex condition was successfully managed through an A3–A3 in situ bypass, branch reconstruction, and trapping accompanied by aneurysmectomy. The multifaceted nature of fusiform lesions precludes the feasibility of endovascular interventions as a sole remedy. In addition, reconstructive and deconstructive approaches exhibit elevated mortality rates in patients experiencing high-grade subarachnoid hemorrhage. 1,4 Given the intricacies intrinsic to this clinical context and the exigent nature of fusiform aneurysms, the surgical therapeutic arsenal embraces a diverse array of surgical methodologies, each offering a bespoke spectrum of techniques meticulously tailored to attain predefined objectives. 3,5-7 These approaches are attuned to promptly abrogate imminent threats, while concurrently mitigating latent complications linked to subarachnoid hemorrhage ensuing from aneurysmal rupture, encompassing the specters of rebleeding, ischemic stroke, and edematous sequelae. 8,9 Crucially, the selection of the most appropriate surgical approach hinges on a comprehensive understanding of available options, patient-specific anatomic considerations, and the preferences of the neurosurgeon. Such a nuanced decision-making process ensures an individualized treatment strategy tailored to optimize patient outcomes. 3,6
