The superior anastomotic vein (or vein of Trolard) is the largest superficial vein on the lateral surface of the parietal or frontal lobe that connects the superior sagittal sinus and the superficial middle cerebral vein (of Sylvius). It usually runs in the post-central sulcus draining the adjacent cortex.

Its size is dictated by the relative size of the superficial middle cerebral vein and the inferior anastomotic vein of Labbé. The vein of Trolard is usually smaller than both of these.
