Vein of Labbe: Vital Brain Venous Channel
The inferior anastomotic vein, also known as the vein of Labbe, is a crucial part of the brain's superficial venous system. Named after French surgeon Charles Labb, this vein plays a significant role in procedures like temporal lobectomy for epilepsy treatment. It is the largest venous channel on the brain's lateral surface, connecting the superficial middle cerebral vein to the transverse sinus. The images provided offer a visual understanding of this important brain structure and its relevance in medical settings, particularly in neurosurgery and imaging techniques.

VEIN OF LABBE ________________________ Michela Rosso
VEIN OF LABBE The inferior anastomotic vein, also known as vein of Labb , is part of the superficial venous system of the brain. It is named after French surgeon Charles Labb (1851- 1889) who described it in his 3rdyear of medical school in 1879 Surgically it is of importance in planning temporal lobectomy for refractory temporal epilepsy, as the vein should be preserved, often requiring some cortical tissue to be left behind.
VEIN OF LABBE It is the largest venous channel on the lateral surface of the brain that crosses the temporal lobe between the Sylvian fissure and the transverse sinus. It courses postero-inferiorly from the mid-Sylvian fissure connecting the superficial middle cerebral vein to the anterolateral portion of the transverse sinus.
VEIN OF LABBE MRI: T1 with contrast
FLAIR: large hemorrhagic venous infarct The thrombus in the right vein of Labbe (arrowheads) is hyperintense on T1
The thrombus in the right vein of Labbe (arrowheads) is hypointense on GRE, and absent bright signal on MRV
