Increased vessel diameter of leptomeningeal anastomoses after hypoxic preconditioning

Recently, cerebral blood flow changes were re-discussed to contribute to tissue protection after preconditioning. In the present study, we demonstrate increased vessel diameters of the leptomeningeal anastomoses after hypoxic preconditioning by visualization of the brain angioarchitecture using the latex perfusion technique. This finding may display the anatomical correlate to previously described perfusion changes after preconditioning.
