METHOD OF PERCUTANEOUS PREOPERATIVE MARKING OF INJURIED MAMMARY GLAND DUCT Russian patent published in 2008 - IPC A61B6/00 A61K49/04 

FIELD: medicine.

SUBSTANCE: ductograms are applied to frontal and lateral projections. Received ductograms show the pathologic focus marked by solution introduction to mammary gland duct. Using straightedge and ductograms data the skin in pathologic focus projection zone is tagged to point needle direction. Mammogram is carried out with marking site in frontal projection. Considering received mammogram data needle is inserted into pathologic focus. Then mammogram is carried out in lateral projection. Then needle mammogram in frontal and lateral projections is compared to ductograms to evaluate and correct needle position. Duct visual marking solution is injected into needle Solution has composition as follows: 75% verografin in amount 0.5 ml and aqueous solution of methylene blue in amount 0.5 ml.

EFFECT: method allows for more precise detection of injury zones and precision removal of mammary gland tissue and for higher detection fraction of intraduct papillomas and initial forms of mammary gland cancer.
