METHOD FOR REPAIRING A THORACIC WALL DEFECT IN STERNUM FAILURE Russian patent published in 2019 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to thoracic surgery, and can be used for the thoracic wall defect elimination. Left and a right greater pectoral muscle is transected intraoperatively at the mid-clavicular line to a small pectoral muscle to form lateral and medial portions of pectoral muscles. Medial portions of the greater pectoral muscles are mobilized from the median-clavicular line from the ribs in the medial direction so that the medial portion of muscles is preserved in the sternal flaps. Left and right muscle flaps are formed from medial portions of large pectoral muscles. Muscular flaps are exposed by free edges to the outside at angle of 180 degrees, in a direction towards each other, a cavity and a defect in the front thoracic wall are closed and filled with muscle flaps. Adjacent edges of muscle flaps are connected to each other by suturing the free end of a muscle flap of the right greater pectoral muscle with a free edge of a muscle flap of the left greater pectoral muscle. Large-mesh polypropylene mesh prosthesis is laid over the developed muscle flaps and fixed to the muscles. Mesh prosthesis is anchored to non-free lateral edges of developed muscular flaps fixed in the sternal cusps; the mesh prosthesis is fixed along the midline to the area of the suture applied between the adjacent edges of the muscular flaps.

EFFECT: method provides elimination of residual cavity in anterior mediastinum, relief of sternomediastinitis phenomena, stabilization of a thoracic cage, without intra-abdominal stage of operation due to use of mobilized medial muscle flaps of great pectoral muscle and immersion thereof in a defect of sternum.
