Labbe Vein

Description

Arcuate along the lateral surface of the temporal lobe, the vein of Labbe (inferior anastomotic vein) courses posteriorly from the superficial middle cerebral vein region toward the transverse sinus. Adjacent cortical landmarks include the superior temporal gyrus inferiorly and the inferior parietal lobule superiorly, with the vessel running superficial to the cortex and deep to the dura at its sinus connections. Superiorly, the superior sagittal sinus and bridging cortical veins sit in the midline dural reflection, while the transverse sinus lies posteroinferiorly along the attached margin of the tentorium cerebelli. Red arterial channels and yellow cranial nerves provide orientation against the blue venous network. Small details matter. Variation of the vein of Labbe is a recurrent issue in lateral skull base and temporal craniotomies, where venous sacrifice can precipitate hemorrhagic venous infarction of the temporal lobe. This view is also useful when correlating angiography and MR venography, because the vein may be dominant, duplicated, hypoplastic, or take an atypical course that shifts its entry point into the transverse sinus. Surgeons often plan dural opening and retractor placement around its trajectory, and neuroradiologists look for thrombosis or outflow obstruction when temporal lobe edema does not match an arterial territory. Neuroanatomy and neurosurgery courses can use this plate to teach superficial cerebral venous drainage patterns alongside dural venous sinuses, and to contrast the vein of Labbe with the vein of Trolard and the superficial middle cerebral vein. It also fits well in operative atlases, radiology teaching files, and patient education materials covering venous thrombosis, temporal lobe approaches, and dural sinus anatomy.
