The inferior anastomotic vein (Labbé's vein) is a superficial cerebral vein that serves as an anastomosis connecting the transverse sinus with the superior sagittal sinus and the superficial middle cerebral vein.
Anatomy
The inferior anastomotic vein drains into the transverse sinus and primarily carries venous blood from the Sylvian fissure area and represents the largest venous connection from the Sylvian fissure to the transverse sinus. The inferior anastomotic vein typically originates from the middle portion of the Sylvian fissure and runs posteriorly and inferiorly towards the anterior portion of the transverse sinus. The inferior anastomotic vein may be doubled as an anatomical variant; in such cases, the posterior of the two veins is more commonly larger[^1].
