METHOD OF THORACOSCOPIC REMOVAL OF THYMUS GLAND Russian patent published in 2025 - IPC A61B17/94 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to thoracic surgery and oncology. Patient is laid down on his/her back with a surgical table inclined to the left in the conditions of separate pulmonary ventilation. Thoracoport is inserted into a right pleural cavity in the VIII intercostal space along a medial axillary line. Thoracoscope is inserted through the thoracoport, and carbon dioxide is insufflated at working pressure 8 mm Hg. Two ports for working instruments are created in the IV intercostal space along anterior axillary and midclavicular lines. After visualizing the right phrenic nerve, a mediastinal pleura is opened in the caudal-cranial direction along the entire length of the mediastinal pleura at a distance from it in the medial direction. Right lobe of thymus is mobilized along its lateral edge. Mouth of a left brachiocephalic vein and a lower venous angle between a medial border of the superior vena cava and a lower border of the left brachiocephalic vein are visualised. Then carbon dioxide insufflation pressure is increased to 10 mm Hg. Thymus is mobilized in the medial direction, from right to left, along an anterior surface and a lower edge of a left brachiocephalic vein, and a tunnel is formed. All thymic veins are visualized and transected successively. Then insufflation pressure is reduced to 8 mm Hg. That is followed by the step-by-step mobilization of a cranial portion of right and left lobes of a thymus. Then in caudal direction gland is mobilized en bloc with fatty tissue of anterior mediastinum and left mediastinal pleura with visual control of left phrenic nerve.

EFFECT: method enables providing higher safety of the thoracoscopic thymus removal in malignant and benign new growths, as well as in nonneoplastic pathologies.
