METHOD FOR ADJUSTMENT OF SECTION PERIMETRES OF TRACHEA AND LEFT PRIMARY BRONCHUS WHEN CREATING TRACHEOBRONCHIAL ANASTOMOSIS Russian patent published in 2012 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely thoracic surgery, and can find application in creating tracheobronchial anastomosis. A method consists in the fact that pre-operative computed tomography is used to derive a base of an incised wedge from a membranous wall of trachea by mathematical calculation. The base of the incised wedge of the membranous wall of trachea is determined by formula X=πR+2(H-R)+N-π(A+B), wherein B is a greater semi-axis of an oval of left primary bronchus, A is a smaller semi-axis of the oval of left primary bronchus, R is a semi-circle radius of front trachea, H is an anteroposterior size of trachea, N is a width of the membranous wall; left primary bronchus is intraoperatively excised parallel to a sectional plane of trachea.

EFFECT: use of the given invention enables higher adjustment of section perimetres of anastomosed end in various versions of trachea bifurcation structure.
