BACKGROUND: The common trunk of the @entity432 (FPA) arising from the A1 segment of the anterior cerebral artery (ACA) associated with a @entity1756 ( @entity439 ), is rare. CASE DESCRIPTION: The @entity1 was a 52-year-old @entity1 who suffered from @entity510 . Three-dimensional computed tomography angiography revealed an elongated and tortuous left A1 segment of the ACA and a saccular @entity439 arising from the left A1 segment of the ACA at the origin of the cortical branch, defining its location just on the midline and behind the anterior communicating artery. This vessel had two branches. One branch ran along the inferior surface of the @entity75 , and the other branch ran anteriorly and medially along the surface of the left hemisphere toward the frontal pole. The anomalous artery was interpreted as a common trunk of the FOA and FPA. Bifrontal craniotomy was performed. The anomalous artery arose from the A1 segment of the ACA at the origin of the @entity439 , and the recurrent artery of Heubner branched off the anomalous artery. The @entity439 was successfully obliterated, clipping with a bayonet-shaped Yasargil @entity702 clip. @entity439 and patency of both the A1 and the common trunk of the FOA and FPA, were confirmed intraoperatively by @entity3194 angiography. CONCLUSIONS: Recognizing this variant preoperatively, could be helpful in preventing the complications of surgery.
