The inferior anastomotic vein (vein of Labbé) is a superficial cerebral vein that, as an anastomosis, connects 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 drains venous blood from the region of the Sylvian fissure, representing the largest venous connection from the Sylvian fissure to the transverse sinus. The inferior anastomotic vein usually originates from the middle portion of the Sylvian fissure and then courses posteriorly and inferiorly toward the anterior portion of the transverse sinus. The inferior anastomotic vein may also be duplicated as an anatomical variant; in such cases, the posterior of the two veins is more often larger[^1].
