Vein of Labbe

vena anastomotica inferior Labbei

The vein of Labbe (inferior anastomotic vein) is an inconstant but clinically important cortical vein connecting the middle cerebral vein of the Sylvian fissure to the transverse sinus, draining the temporal lobe. It bridges the superficial middle cerebral venous system above with the transverse sinus below, and when present it is a large, dominant temporal lobe draining vein whose sacrifice causes temporal lobe venous infarction.

Clinical Notes

The vein of Labbe is the critical structure at risk during temporal craniotomy and middle fossa approaches. If it is sacrificed during brain retraction or surgical resection, temporal lobe venous infarction, haemorrhage, and swelling produce a devastating result with aphasia and visual field loss in the dominant hemisphere. Preoperative MR venography and planning of the craniotomy to cross the vein safely, combined with gentle retraction technique, are essential. The vein's anatomy is highly variable; it may be absent, small, or enormous.

Pathology

Common Injuries & Conditions

Temporal Lobe Venous Infarction from Vein of Labbe Injury

Laceration or thrombosis of the vein of Labbe during temporal craniotomy or the temporal lobe retraction required for middle fossa and posterior communicating artery aneurysm surgery causes temporal lobe venous hypertension, haemorrhagic infarction, brain swelling, and permanent deficit, making preoperative identification of its anatomy mandatory.
