[Thoracoscopic resection of azygos vein aneurysm].

Azygos vein aneurysm is a rare thoracic disease that often mimics posterior mediastinum tumors. Pathogenesis of azygos vein aneurysm is unclear. Discussions about possible causes are still ongoing.

[Soft tissue emphysema in spontaneous pneumothorax. Features of medical approaches].

Soft tissue emphysema (including subcutaneous emphysema) is common in pneumothorax. In most cases, this condition is of little clinical significance and regresses under standard medical procedures. However, progressive soft tissue emphysema poses a threat to the patient's life in case of compression of the upper respiratory tract in some cases.

[Chest wall morphological changes after sternal reconstruction with titanium mesh implant in patients with sternum instability].

Sternal instability is the one of the unresolved problems in open cardiac surgery (1-8%). The risk of recurrence after repeated osteosynthesis is up to 20% in these patients. Repeated osteosynthesis is impossible in some cases, and this complicates anterior chest wall reconstruction.

[Surgical approach for destructive pneumonia associated with COVID-19].

There were over 400 million people with COVID-19 pneumonia worldwide and over 12 million in the Russian Federation after 2020. Complicated course of pneumonia with abscesses and gangrene of lungs was observed in 4% of cases. Mortality ranges from 8 to 30%.

[Intercostal nerve cryoablation in correction of pectus excavatum in adults].

Objective: To evaluate an effectiveness of cryoanalgesia in older patients with pectus excavatum and to determine feasibility of further research.

Material And Methods: We have developed an original technique of intercostal nerve cryoablation for correction of pectus excavatum in adults. The results of intercostal nerve cryoablation during correction of pectus excavatum in 10 older patients were analyzed.
