Phlebography of the cavernous and intercavernous sinuses

The study of pituitary diseases is described, with visualization of the cavernous and intercavernous sinuses accomplished through percutaneous, transfemoral catheterization, using special methods to ensure its reliability. The most characteristic normal and pathological findings are described. The value of this method and the indications for its use in diagnosis are discussed. The possibility of combining morphological investigations with regional functional studies of pituitary hormones by selective blood sampling is suggested. This technical development opens new prospects for the future and further broadens the indications for use of this procedure.
