This study demonstrates that abnormal vascular embryogenesis can lead to complex vascular variants. Clinicians should remain vigilant for potential hemodynamic irregularities and take prompt action to prevent larger aneurysms from forming and enlarging. Precise identification and thorough preoperative evaluation are crucial for reducing surgical risks and avoiding serious complications, such as infarction. Detailed knowledge of these variations is critical for imaging, interventional procedures, and surgery involving the cervical and cerebral vessels.
