Treatment of post-resuscitation cicatricial tracheal stenosis after suffering severe COVID-19 associated pneumonia: A report of 11 cases.

Objective: Despite the full range of anti-epidemic measures, the rapidly mutating SARS-CoV-2 continues to spread worldwide, causing respiratory and pulmonary pathologies. So far, there are no generally accepted clinical guidelines for treating post-resuscitation cicatricial tracheal stenosis (CTS) after COVID-19 associated pneumonia. This study sought to evaluate the clinical outcomes of surgical treatment and perioperative management of patients who developed CTS.

Repair of huge thoracic defect combined with hernia after multimodality treatment of breast cancer.

A case of the successful reconstruction of an extensive chest wall defect combined with a ventral hernia in a patient after multimodality treatment of breast cancer complicated by sternal and costal osteomyelitis is presented. To recover the chest mechanics, with emphasis on the supporting function, and to repair the hernial defect, customized reinforced "sandwich" TiNi rib endografts and knitted TiNi surgical mesh were used. A five-year follow-up indicated no recurrence of osteomyelitis or ventral hernia, and no failure/migration of the implants or instability of the thorax.

Evaluation of Clinical Performance of TiNi-Based Implants Used in Chest Wall Repair after Resection for Malignant Tumors.

Unlabelled: In this study, we assessed the outcomes after surgical treatment of thoracic post-excision defects in 15 patients, using TiNi knitted surgical meshes and customized artificial TiNi-based ribs.

Methods: Eight patients were diagnosed with advanced non-small cell lung cancer (NSCLC) invading the chest wall, of which five patients were TNM, two were TNM, and one was TNM. Squamous cell carcinoma was identified in three of these patients and adenocarcinoma in five.

Study on tensile, bending, fatigue, and in vivo behavior of porous SHS-TiNi alloy used as a bone substitute.

Intermetallic porous SHS-TiNi alloys exhibit tangled and specific stress-strain characteristics. This article aims to evaluate the findings emanating from experiments using standard and proprietary instruments. Fatigue testing under repeated complex loading was used to measure the total number of load cycles before failure of the SHS-TiNi samples occurred.
