Abstract
BACKGROUND Completion lobectomy (CL) following a prior resection in the same lobe may be complicated by severe pleural or hilar adhesions. The role of uniportal video-assisted thoracoscopic surgery (U-VATS) has never been evaluated in this setting. METHODS Data were collected from two Italian centers. Between 2015 and 2022, 122 patients (60 men and 62 women, median age 67.7 ± 8.913) underwent U-VATS CL at least 4 weeks after previous lung surgery. RESULTS Twenty-eight (22.9%) patients were affected by chronic obstructive pulmonary disease (COPD) and twenty-five (20.4%) were active smokers. Among the cohort, the initial surgery was performed using U-VATS in 103 (84.4%) patients, triportal-VATS in 8 (6.6%), and thoracotomy in 11 (9.0%). Anatomical segmentectomy was the initial surgery in 46 (37.7%) patients, while hilar lymphadenectomy was performed in 16 (13.1%) cases. CL was performed on 110 (90.2%) patients, segmentectomy on 10 (8.2%), and completion pneumonectomy on 2 (1.6%). Upon reoperation, moderate pleural adhesions were observed in 38 (31.1%) patients, with 2 (1.6%) exhibiting strong adhesions. Moderate hilar adhesions were found in 18 (14.8%) patients and strong adhesions in 11 (9.0%). The median operative time was 203.93 ± 74.4 min. In four (3.3%) patients, PA taping was performed. One patient experienced intraoperative bleeding that did not require conversion to thoracotomy. Conversion to thoracotomy was necessary in three (2.5%) patients. The median postoperative drainage stay and postoperative hospital stay were 5.67 ± 4.44 and 5.52 ± 2.66 days, respectively. Postoperative complications occurred in 34 (27.9%) patients. Thirty-day mortality was null. Histology was the only factor found to negatively influence intraoperative outcomes (p = 0.000). Factors identified as negatively impacting postoperative outcomes at univariate analyses were male sex (p = 0.003), age > 60 years (p = 0.003), COPD (p = 0.014), previous thoracotomy (p = 0.000), previous S2 segmentectomy (p = 0.001), previous S8 segmentectomy (p = 0.008), and interval between operations > 5 weeks (p= 0.005). In multivariate analysis, only COPD confirmed its role as an independent risk factor for postoperative complications (HR: 5.12, 95% CI (1.07-24.50), p = 0.04). CONCLUSIONS U-VATS CL seems feasible and safe after wedge resection and anatomical segmentectomy.

Abstract
Broncho-pleural fistula (BPF) is an abnormal communication between the bronchial lumen and the pleural space that typically occurs postoperatively. Surgical intervention is typically needed to patch the fistula; however, current literature lacks a gold standard for which treatment to use. With a high mortality rate, there is a clear urgency for quick and successful intervention. This case examines a 59-year-old patient presenting with a BPF 14 years after incidental pneumonectomy during upper lobectomy for invasive aspergillus. A fistula was appreciated during bronchoscopy with contrast injection. The fistula was closed via the transsternal approach through median sternotomy and pericardiotomy. This case report aims to provide a viable option to successfully repair a BPF via the transsternal approach.

Abstract
Shock is the clinical presentation of circulatory failure with impaired perfusion that results in inadequate cellular oxygen utilization. Treatment requires properly identifying the type of shock that is impacting the patient (obstructive, distributive, cardiogenic, and/or hypovolemic). Complex cases may involve numerous contributors to each type of shock and/or multiple types of shock which can present interesting diagnostic and management challenges to the clinician. In this case report, we present a 54-year-old male with a remote history of a right lung pneumonectomy presenting with multifactorial shock including cardiac tamponade, with initial compression of the expanding pericardial effusion by the postoperative fluid accumulation within the right hemithorax. While in the emergency department, the patient gradually became hypotensive with worsening tachycardia and dyspnea. A bedside echocardiogram revealed an increase in size of the pericardial effusion. An emergent ultrasound-guided pericardial drain was inserted with gradual improvement of his hemodynamics followed by placement of thoracostomy tube. This unique case highlights the importance of utilizing point-of-care ultrasound along with emergent intervention in critical resuscitation.

Abstract
BACKGROUND In this study, we aimed to summarize the extremely important lesson and experience in the whole process of surgical treatments of lung tumors for the benefit of steps taken to prevent against unplanned reoperation. METHODS Demographical and clinical information of 7732 patients were retrospectively retrieved and reviewed, who were diagnosed with pulmonary tumor and underwent surgical treatments from January 2016 to March 2021. Those patients who underwent unplanned reoperation for the treatment of severe complications were focused carefully and analyzed meticulously. RESULTS A total of forty-one patients (41/7732) received 44 unplanned reoperations. Among them, eight and thirty-three patients were diagnosed with benign and malignant tumor, respectively. The incidence of unplanned reoperations seemed to be similar on both sides (Left vs. Right: 12/3231 vs. 29/4501, p = 0.103). Lobectomy plus segmentectomy is prone to reoperation (2/16, 12.5%) as compared to the other types of surgery. The complications leading to reoperation was hemothorax, including active hemorrhage (23/44, 52.3%) and clotted hemothorax (6/44, 13.6%), chylothorax (8/44, 18.2%), and the others (7/44, 15.9%) including bronchopleural fistula, torsion, or injury of right middle bronchus and pulmonary bulla rupture. The morbidity and mortality after unplanned reoperation were 17.1% (7/41) and 12.2% (5/41), respectively. CONCLUSIONS Bronchi or vessel stumps, the surgical edges of the lung parenchyma, and pleural adhesions should be checked to avoid postoperative bleeding. Prophylactic ligation of the thoracic duct should be recommended in case of the suspected oily-like exudation in the lymph node bed. Smooth expansion of the middle lobe is important to avoid narrowing and torsion before transection of the bronchus.

Abstract
Abstract
Background
Bronchopleural fistula (BPF) is a serious complication with high mortality and morbidity that can be seen after lung resections. Although several methods have been described to prevent postoperative BPF it is still unclear which method is the best. In this study, we have used tymopericardial fat flap (TPFF) to cover the bronchial stump in patients after pneumonectomy and aim to show its feasibility and efficacy to prevent BPF.
Methods
Between January 2013 and June 2021, 187 patients with lung cancer underwent pneumonectomy at our institution. Among them, 53 patients underwent bronchial stump coverage with TPFF. In other 134 patients there wasn’t used any coverage method. Patient characteristics, preoperative status, surgical procedures, perioperative course, pathological findings, and long-term prognoses were evaluated retrospectively.
Results
Postoperative BPF was observed in 16 (%8.5) patients. It was observed that TPFF was applied in only 1 of the patients who developed BPF. A statistically significant difference was detected between TPFF-coverage with non-coverage groups in terms of postoperative BPF rates (p = 0.044). Other factors associated with the development of postoperative BPF in univariate analysis were right sided pneumonectomy, and re-operation.
Conclusion
Bronchial stump coverage with TPFF is a feasible and effective method to prevent postpneumonectomy BPF.

Abstract
BACKGROUND AND OBJECTIVE Lobectomy is a curative treatment for localized lung cancer. The study aims to construct an automatic pipeline for segmenting pulmonary lobes before and after lobectomy from CT images. MATERIALS AND METHODS Six datasets (D1 to D6) of 865 CT scans were collected from two hospitals and public resources. Four nnU-Net-based segmentation models were trained. A lobectomy classification was proposed to automatically recognize the category of the input CT images: before lobectomy or one of five types after lobectomy. Finally, the lobe segmentation before and after lobectomy was realized by integrating the four models and lobectomy classification. The dice similarity coefficient (DSC), 95% Hausdorff distance (HD95) and average symmetric surface distance (ASSD) were used to evaluate the segmentations. RESULTS The pre-operative model achieved an average DSC of 0.964, 0.929, 0.934, and 0.891 in the four datasets. In D1 and D2, the average HD95 was 4.18 and 7.74 mm and the average ASSD was 0.86 and 1.32 mm, respectively. The lobectomy classification achieved an accuracy of 100%. After lobectomy, an average DSC of 0.973 and 0.936, an average HD95 of 2.70 and 6.92 mm, an average ASSD of 0.57 and 1.78 mm were obtained in D1 and D2, respectively. The postoperative segmentation pipeline outperformed other counterparts and training strategies. CONCLUSIONS The proposed pipeline can automatically segment pulmonary lobes before and after lobectomy from CT images and be applied to manage patients with lung cancer after lobectomy.

Abstract
A 62-year-old woman with a history of lung resection for lung cancer was admitted to our hospital due to cough, which became progressively more severe. She was diagnosed with chronic empyema with bronchopleural fistula (BPF) of the right upper bronchial stump. Although a pedicled muscle flap was transposed to the empyema cavity, the fistula remained. We used a vacuum-assisted closure system after open-window thoracotomy and observed the cavity reduction with expansion of the transposed muscle flap. We quantitatively evaluated the dynamics of the cavity change using a three-dimensional image analysis system. A reduction of the volume of the muscle flap by prolonged empyema and expansion of the muscle flap was observed immediately after vacuum-assisted management. However, expansion of the right residual lung was not recognized. Pedicled muscle flap transposition followed by vacuum-assisted management after open-window thoracotomy may be effective for treating chronic empyema caused by BPF.

[PMID: 35228582 PMCID: PMC8885819 DOI: 10.1038/s41598-022-06852-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 12/14/2021] [Indexed: 12/25/2022] Open
Abstract
Pulmonary lobectomy, which consists of the partial or complete resection of a lung lobe, is the gold standard intervention for lung cancer removal. The removal of functional tissue during the surgery and the re-adaptation of the remaining thoracic structures decrease the patient's post-operative pulmonary function. Residual functionality is evaluated through pulmonary function tests, which account for the number of resected segments without considering local structural alterations and provide an average at-the-mouth estimation. Computational Fluid Dynamics (CFD) has been demonstrated to provide patient-specific, quantitative, and local information about airways airflow dynamics. A CFD investigation was performed on image-based airway trees reconstructed before and after the surgery for twelve patients who underwent lobectomy at different lobes. The geometrical alterations and the variations in fluid dynamics parameters and in lobar ventilation between the pre and post-operative conditions were evaluated. The post-operative function was estimated and compared with current clinical algorithms and with actual clinical data. The post-operative configuration revealed a high intersubject variability: regardless of the lobectomy site, an increment of global velocity, wall pressure, and wall shear stress was observed. Local flow disturbances also emerged at, and downstream of, the resection site. The analysis of lobar ventilation showed severe variations in the volume flow rate distribution, highlighting the compensatory effects in the contralateral lung with an increment of inflow. The estimation of post-operative function through CFD was comparable with the current clinical algorithm and the actual spirometric measurements. The results confirmed that CFD could provide additional information to support the current clinical approaches both in the operability assessment and in the prescription of personalized respiratory rehabilitation.

Abstract
A variety of surgical procedures are utilized to treat a spectrum of cardiopulmonary diseases. In the imaging of patients in the post-operative period, it is important to have an understanding of surgical techniques including invasive and minimally invasive procedures and the expected postsurgical findings. Knowledge of certain patient risk factors, various complications associated with specific surgical procedures, and a keen attention to detail are essential to avoid misinterpretation and delay diagnosis. Prompt detection of potential complications allows timely intervention, thereby, optimizing patient outcomes in the post-operative period.

INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN BIOMEDICAL ENGINEERING 2021; 37:e3462.

Abstract
Pulmonary lobectomy is the gold standard intervention for lung cancer removal and consists of the complete resection of the affected lung lobe, which, coupled with the re-adaptation of the remaining thoracic structures, decreases the postoperative pulmonary function of the patient. Current clinical practice, based on spirometry and cardiopulmonary exercise tests, does not consider local changes, providing an average at-the-mouth estimation of residual functionality. Computational Fluid Dynamics (CFD) has proved a valuable solution to obtain quantitative and local information about airways airflow dynamics. A CFD investigation was performed on the airway tree of a left-upper pulmonary lobectomy patient, to quantify the effects of the postoperative alterations. The patient-specific bronchial models were reconstructed from pre- and postoperative CT scans. A parametric laryngeal model was merged to the geometries to account for physiological-like inlet conditions. Numerical simulations were performed in Fluent. The postoperative configuration revealed fluid dynamic variations in terms of global velocity (+23%), wall pressure (+48%), and wall shear stress (+39%). Local flow disturbances emerged at the resection site: a high-velocity peak of 4.92 m/s was found at the left-lower lobe entrance, with a local increase of pressure at the suture zone (18 Pa). The magnitude of pressure and secondary flows increased in the trachea and flow dynamics variations were observed also in the contralateral lung, causing altered lobar ventilation. The results confirmed that CFD is a patient-specific approach for a quantitative evaluation of fluid dynamics parameters and local ventilation providing additional information with respect to current clinical approaches.

Abstract
OBJECTIVE To analyze the anatomometric characteristics of post-pneumonectomy cavity and their changes at various times after surgery. MATERIAL AND METHODS The study included 47 patients aged 39-75 years after pneumonectomy (right-sided - 23 cases, left-sided - 24 cases). Computed tomography was performed prior to surgery, in 10-12 days, 6 and 12 months after intervention. Transverse, anteroposterior dimensions, height and volume of pleural cavity were evaluated using CT scans and 3D models. RESULTS Post-pneumonectomy cavity decreases and changes own shape in postoperative period. Reduction is mainly caused by decrease in its height. The volume of post-pneumonectomy cavity was decreased in early postoperative period by 1.8 times compared to preoperative values (from 3351.5±150.0 cm3 to 2112.1±152.6 cm3 on the right side and from 2674.3±125.2 cm3 to 1460.1±84.1 cm3 on the left side). After 12 months, this value was reduced by 3.68 times compared to early postoperative period (714.3±100.7 cm3 on the right and 401.5±42.5 cm3 on the left). The shape changes consist of flattening and sinus depth reduction. Exudate density was similar throughout a year. The capsule was formed in 74.1% of patients after 12 months. There was no correlation between the cavity reduction and patient constitution. CONCLUSION Post-pneumonectomy cavity is a dynamically changing anatomical formation participating in the mechanisms of compensation for changes after pneumonectomy. The most significant collapse of post-pneumonectomy cavity occurs in early postoperative period. Cavity reduction degree does not depend on individual characteristics of patients.

Abstract
We present the case of a 19 year old female presenting to the Emergency Department with signs of pneumonia and sepsis, with her clinical status deteriorating rapidly to septic shock and respiratory failure. Her pneumonia was complicated by formation of an empyema and a bronchopleural fistula. Bronchopleural fistula (BPF) is a fistula between pleural space and a bronchus. It is an uncommon complication of lung surgery, endobronchial interventions or chest trauma. They are sometimes formed secondary to postoperative pneumonia. Management of BPF requires surgical or bronchoscopic intervention with supportive care. Since a BPF can cause physiological tension pneumothorax, it can lead to significant worsening of respiratory status of these patients. Ventilator settings need to be adjusted to reduce the Positive end expiratory pressure and tidal volume to support these patients. With this case we highlight the importance of recognizing and diagnosing a BPF and timely management of a BPF in the emergency setting to help patients get to the definitive treatment of the fistula.

Abstract
Background
This study aims to examine preoperative white blood cell count and lymphocyte/monocyte ratio and to investigate foreknown risk factors for pneumonia following lobectomy.
Methods
Between January 2005 and May 2018, a total of 152 patients (135 males, 17 females; mean age: 61.9±7.5 years; range, 45 to 73 years) who underwent right lower lobectomy for non-small cell lung cancer were retrospectively analyzed. Data including age, sex, preoperative white blood cell count and lymphocyte/monocyte ratio, smoking, preexisting chronic diseases, body mass index, stage of lung cancer, the use of neoadjuvant chemotherapy, type of surgery, operation duration, blood transfusion, and postoperative intensive care unit admission were recorded.
Results
Twenty-five (16.4%) patients developed postoperative pneumonia. Older patients presenting with elevated levels of preoperative white blood cell count and lymphocyte/monocyte ratio, excessive tobacco consumption, prolonged operation duration, history of a chronic disease, a body mass index over 30 kg/m2, advanced lung cancer, neoadjuvant chemotherapy, and intensive care unit admission after surgery were at high risk for postoperative pneumonia. There was no significant difference in sex, type of surgery (thoracotomy versus thoracoscopy), and the use of blood products. In predicting the development of postoperative pneumonia, lymphocyte/monocyte ratio had 85.% sensitivity and 87.5% specificity, while white blood cell count had 72.5% sensitivity and 77.5% specificity.
Conclusion
Preoperative white blood cell count and lymphocyte/ monocyte ratio provide supporting evidence in predicting pneumonia following lobectomy contributing to the existing risk identification criteria.

Abstract
Lung cancer is currently the most common malignancy in the world. A lobectomy is the standard of care for most patients with operable lung cancer and accounts for 60% to 70% of lung resection. The chest radiograph may appear normal after a lobectomy, particularly in uncomplicated cases. However, lobectomy usually involves leaving surgical staples at the bronchial stump and causes various changes in the intra- and extrapulmonary thoracic structures on plain radiographs. These changes may differ according to the resected lobe. We retrospectively evaluated the plain radiographic appearances of the postlobectomy chest, free of postoperative complications or recurrent/metastatic lung cancer. On the basis of our observations, the changes that occur in pulmonary and extrapulmonary anatomy can differ according to the resected lobe. Recognition of these changes will make it easier to identify which lobe has been removed surgically.

Abstract
Thoracic surgery has seen a resurgence in recent years with increasing numbers of cases taken on since the mid-2000s. There has been a paradigm shift in how we manage lung cancer with more emphasis on surgical resection, and this has been aided by minimally invasive video-assisted thoracic surgery (VATS) techniques. As a result, the prevalence of postoperative findings and complications is also increasing, and it is increasingly important for the general radiologist to recognise and diagnose these conditions as thoracic surgical patients may present acutely to non-thoracic surgical institutions. This review will cover both the early and late complications following a variety of lung resection surgeries.

Abstract
Background Pulmonary lobectomy has been a well-established curative treatment method for localized lung cancer. After left upper pulmonary lobectomy, the upward displacement of remaining lower lobe causes the distortion or kink of bronchus, which is associated with intractable cough and breathless. However, the quantitative study on structural and functional alterations of the tracheobronchial tree after lobectomy has not been reported. We sought to investigate these alterations using CT imaging analysis and computational fluid dynamics (CFD) method. Methods Both preoperative and postoperative CT images of 18 patients who underwent left upper pulmonary lobectomy are collected. After the tracheobronchial tree models are extracted, the angles between trachea and bronchi, the surface area and volume of the tree, and the cross-sectional area of left lower lobar bronchus are investigated. CFD method is further used to describe the airflow characteristics by the wall pressure, airflow velocity, lobar flow rate, etc. Results It is found that the angle between the trachea and the right main bronchus increases after operation, but the angle with the left main bronchus decreases. No significant alteration is observed for the surface area or volume of the tree between pre-operation and post-operation. After left upper pulmonary lobectomy, the cross-sectional area of left lower lobar bronchus is reduced for most of the patients (15/18) by 15–75%, especially for 4 patients by more than 50%. The wall pressure, airflow velocity and pressure drop significantly increase after the operation. The flow rate to the right lung increases significantly by 2–30% (but there is no significant difference between each lobe), and the flow rate to the left lung drops accordingly. Many vortices are found in various places with severe distortions. Conclusions The favorable and unfavorable adaptive alterations of tracheobronchial tree will occur after left upper pulmonary lobectomy, and these alterations can be clarified through CT imaging and CFD analysis. The severe distortions at left lower lobar bronchus might exacerbate postoperative shortness of breath.

Abstract
Many surgical procedures are used for the treatment of lung, heart, and mediastinal diseases. The techniques can result in postoperative complications. The nature of these complications differs according to the duration of thoracic surgery and the onset of the complication. The complications occurring within 1 month and more than 1 month generally considered as early and late complications, respectively. Chest radiographs and CT scans obtained in patients who have undergone thoracic surgery show normal changes during the surgical procedure and diverse postsurgical complications. Familiarity with the clinical and radiologic findings of the normal alterations and possible complications after thoracic surgery is crucial in minimizing the increased morbidity and mortality.

Abstract
Complications following cardiothoracic surgery are responsible for prolonged hospital stay, increase cost in patient care and increased morbidity and mortality. Vascular complications in particular are significant contributors to poor patient outcome due to either hemorrhage or thrombosis and ischemia. Evaluation of vascular complications in the postoperative patient requires a rapid and reliable imaging approach. Vascular complications after cardiothoracic surgery include pulmonary artery thrombosis, pseudoaneurysm, pulmonary vein thrombosis, vascular fistulas, stenosis and infarction. Multidetector CT (MDCT), often the imaging modality of choice, offers a one-stop-shop capability to visualize the entire cardiothoracic vasculature, airways, lung parenchyma, mediastinum and chest wall with excellent temporal and spatial resolution.

Abstract
The major lung resections are the pneumonectomies and lobectomies. The sublobar resections are segmentectomies and wedge resections. These are performed either through open surgery through a thoracotomy or by video-assisted mini-invasive surgery for lobectomies and sublobar resections. Understanding the procedures involved allows the normal postoperative appearances to be interpreted and these normal anatomical changes to be distinguished from potential postoperative complications. Surgery results in a more or less extensive physiological adaptation of the chest cavity depending on the lung volume, which has been resected. This adaptation evolves during the initial months postoperatively. Chest radiography and computed tomography can show narrowing of the intercostal spaces, a rise of the diaphragm and shift of the mediastinum on the side concerned following major resections.

Abstract
We describe a patient who presented with a bilateral pulmonary artery sarcoma, initially treated as pulmonary embolism, that necessitated concomitant pulmonary endarterectomy and pneumonectomy. We reviewed the anesthetic management used for this procedure, which bears many similarities to the management of patients undergoing pulmonary thromboendarterectomy. Right ventricular failure, pulmonary hemorrhage, and cerebral ischemia due to circulatory arrest are life-threatening perioperative complications. The anesthesiologist can play a key role in the prevention (or timely recognition and treatment) of these perioperative complications by establishing adequate hemodynamic, echocardiographic, and neurologic monitoring and by optimizing cardiopulmonary function and coagulation.
