METHOD OF SURGICAL TREATMENT OF EXPIRATORY STENOSIS OF TRACHEA AND MAIN BRONCHI Russian patent published in 2009 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to thoracic surgery and can be applied in surgical treatment of expiratory stenoses of trachea and main bronchi. Essence of method lies in trachea intubation, mobilisation and visualisation of region of pathologic invagination of membranous part of trachea with further enforcement of changed area with implant. Access is realised extrapleurally through upper thoracic aperture. Trachea intubation is performed with endotracheal tube equipped with cup. Nasogastral probe is installed, area of pathologic invagination is enforced with plate from porous-permeable titanium nickelide of concave form, 0.9-1 mm thick, 40-70% porosity and pore size 100-1000 mcm, installing it in such way that it overlaps in length borders of changed region, plate is pressed to membranous part of trachea by bringing surrounding tissues together. If area of pathologic invagination is located at the level of cervical and upper thoracic regions of trachea, operation is performed in open way, and if area of pathologic invagination is located at the level of bifurcation and at the level of main bronchi - with application of mediastinoscope.

EFFECT: application of claimed invention allows to reduce traumaticity and increase treatment efficiency due to application of extrapleural access and biocompatible implant based on porous titanium nickelide.
