摘　　要：BACKGROUND The diagnosis and therapy during surgery depend largely on a full account of anatomic characteristics.Apart from regular structures,the common,less common or even uncommon anatomic variations are critical for procedural planning.This is especially true during craniocerebral microsurgery,where small vascular variations can affect the final surgical results and patient prognosis.CASE SUMMARY Herein,two rare variations concerning the A1(horizontal)segment of anterior cerebral artery(ACA1)were introduced.One enabled the communication between perforating branch of ACA1 and dural artery of anterior skull base,which was discovered during autopsy.The other was ophthalmic artery(OA)originating from ACA1,shown on digital angiography.CONCLUSION In this study,we found two rare anatomical variations.One was an abnormal OA originated from the anterior communicating artery.The other was a perforating branch of the A1 segment of the anterior cerebral artery,which communicated with meningeal vessels in the anterior skull base.This finding is of great significance for the treatment of anterior communicating artery aneurysm or in other anterior skull base surgery.
