[Orbital phlebography craniobasal meningiomas spreading into the orbit]

Analysis of the results of orbital phlebography performed in 39 patients with cranio-orbital meningiomas testifies to the important diagnostic value of this methods of examination in determining the spread of craniobasal meningiomas to the orbit. By means of orbital phlebography it is possible not only to precisely define the topography of the new growth in the orbital cavity, but to reveal disorders of venous drainage from the orbit and collateral tracts which provide the draining function of the superior ophthalmic vein.
