inferior anastomotic vein

A vein that is tributary of the transverse sinus and drains blood from the adjacent cortical regions of the temporal lobe. The inferior anastomotic vein forms an anastomosis (connection) between the superficial middle cerebral vein anteriorly and the transverse sinus posteriorly.

Frequently Asked Questions

What is the inferior anastomotic vein?
The inferior anastomotic vein, also known as the vein of Labbé, is a superficial cerebral vein that forms an anastomosis between the superficial middle cerebral vein anteriorly and the transverse sinus posteriorly. It drains blood from the adjacent cortical regions of the temporal lobe.
Where is the inferior anastomotic vein located?
The inferior anastomotic vein is located on the lateral surface of the temporal lobe of the brain. It courses over the temporal cortex, connecting the superficial middle cerebral vein (which runs along the Sylvian fissure) anteriorly to the transverse sinus posteriorly.
What is the function of the inferior anastomotic vein?
The inferior anastomotic vein drains venous blood from the cortical regions of the temporal lobe and serves as a connecting channel between the superficial middle cerebral vein and the transverse sinus. It contributes to the venous drainage of the lateral temporal cortex.
What conditions may be associated with the inferior anastomotic vein?
The inferior anastomotic vein is an important landmark in neurosurgery, as it must be preserved during temporal approaches to avoid venous infarction of the temporal lobe. Thrombosis or injury of this vein may be associated with neurological effects. Clinical evaluation is required for any specific concern.
How is the inferior anastomotic vein examined?
The inferior anastomotic vein can be visualized with MR venography, CT venography, or conventional cerebral venography when detailed mapping of superficial cerebral veins is needed. It is directly identified during craniotomy procedures involving the temporal lobe.
