METHOD OF SIMULTANEOUS BILATERAL CATHETERIZATION OF CAVERNOUS AND INFERIOR PETROSAL SINES WITH SAMPLING VENOUS BLOOD FOR EVALUATION OF ADRENOCORTICOTROPIC HORMONE AND PROLACTIN LEVEL Russian patent published in 2020 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to neurosurgery. Through the introducers installed bilaterally into the femoral vein, guide catheters are introduced into the internal jugular veins. Further, microcatheters are brought through guide catheters by means of microconductors to the posterior cavernous sinuses. Sinusography is performed, followed by double sampling of venous blood every 2 minutes. Thereafter, the microcatheters are lowered to the inferior petrosal sinuses at the level above the sphincter with the vertebral venous plexus. Blood samples of inferior petrosal sinuses are sampled. Microcatheters are removed from the vascular bed. Further, guiding catheters are used to draw blood of internal jugular veins, as well as from upper and lower hollow veins above and below the mouth of renal veins.

EFFECT: method enables adequate sampling of venous blood to confirm a source of hyperproduction of ACTH and prolactin and adequate surgical management, while reducing the risk of diagnostic error and recurrent hypercortisolism.
