Introduction: Abnormal branching of the pulmonary artery is often encountered in anatomical lung resection, which can potentially result in accidental vessel injury with life-threatening bleeding or extra lung resection. The mediastinal basal pulmonary artery (Arteria Praebronchialis, AP) is a very rare but potentially critical variant.

Presentation Of Case: We present the case of a patient with lung cancer accompanied by the left basal segmental pulmonary artery, independent A, which was liable to be injured during lower lobectomy with poor interlobar fissure development.

Background: There are few basic comparative data on the sealing effect of various bioabsorbable sheets in combination with fibrin sealant (FS), which is a more effective tool for the control of alveolar air leakage than the single use of FS alone. The objective of this study was to investigate which bioabsorbable sheet had the best sealing effect against alveolar air leakage when used in combination with FS, in terms of material quality, weaving pattern, and/or thickness.

Methods: Standardized 20 mm × 30 mm pleural defects were covered with three pieces of the following sheets using the Rub + Soak B technique in an porcine lung model.

The objective of this study was to investigate the efficacy of intraoperative Cell Saver blood salvage during emergency surgery for massive hemothorax on minimizing perioperative allogeneic red blood cell (RBC) transfusion. Fourteen consecutive patients of massive hemothorax with more than 800 cc of intrathoracic bleeding estimated by chest X-ray and/or chest computed tomography (CT) scan at presentation between 2009 and 2021 were retrospectively reviewed. Intraoperative Cell Saver blood salvage was performed in 11 patients (Cell Saver group) with a median volume of 820 cc (range, 421-1700 cc).

Heterologous mesothelioma is a very rare subtype of sarcomatoid mesothelioma characterized by the presence of malignant heterologous elements. A 69-year-old man with a strong history of asbestos exposure presented with a 5-cm mass in his chest wall, destroying the right 5th rib and spreading along the parietal pleura, on a CT. Biopsy revealed heterologous mesothelioma with osteosarcomatous elements, following which left extrapleural pneumonectomy was performed with combined resection of pericardium, hemidiaphragm, and 4th, 5th, and 6th costal segments.

Central airway obstruction caused by cancer requires urgent interventional pulmonology. Malignant main carinal involvement is one of the most challenging situations, usually treated by rigid bronchoscopic intervention under general anaesthesia. However, these patients tend to be in poor condition due to underlying malignancy.
