- Blunt Trauma and Right Diaphragmatic Rupture: Unveiling the ImpactPublication . Alves, D; Sousa, J; Eurico Reis, J; Ribeiro, R; Calvinho, PTraumatic diaphragmatic ruptures are rare, yet blunt injuries tend to be more easily overlooked compared to penetrating trauma. The minimal evidence of external injuries makes a high index of suspicion key for diagnosis. We report the case of a right-sided thoracoabdominal blunt trauma that resulted in a diaphragmatic rupture and fractured rib. Although often approached through a midline laparotomy, a definitive right thoracotomy repair was exceptionally performed since the adjacent peritoneum remained uninjured.

- Combined Lung-Kidney Transplantation: First Case in PortugalPublication . Silva, D; Dantas, C; Santos, AS; Silva, C; Aires, I; Remédio, F; Carrelhas, S; Pena, A; Eurico Reis, J; Calvinho, P; Semedo, L; Cardoso, J; Nolasco, F; Fragata, JA significant dysfunction of another organ is usually considered an absolute contraindication for lung transplantation, unless multiorgan transplantation is indicated and practical, as is the case of combined lung-kidney transplantation. Few cases of combined lung-kidney transplantation have been described in the literature; however, it is known that, in certain cases, it is the only way to offer an opportunity to selected patients with renal and lung dysfunction. The authors are not aware of any previously published case of a patient receiving both extracorporeal membrane oxygenation and continuous venovenous hemodiafiltration as a bridge for combined kidney-lung transplantation. The authors present the first case of combined lung-kidney transplantation performed in Portugal.
- Extracorporeal Life Support Use in Limited Lung Function: a Narrative ReviewPublication . Santos Silva, J; Cabral, D; Calvinho, P; Olland, A; Falcoz, PEBackground and objective: In thoracic surgery, different modalities of extracorporeal life support (ECLS) can be used for cardiorespiratory support in complex scenarios. Decades of learning in clinical practice and physiology associated with technological development led to a great variety of ECLS technologies available. Thoracic surgery procedures with difficult or impossible single lung ventilation may still be performed using different ECLS modalities. The aim of this review is to describe the use of ECLS, with its different modalities, as a solution to perform complex surgeries in a patient with difficult or impossible single lung ventilation. Methods: A literature review was conducted using the terms "extracorporeal life support pulmonary resection" and "extracorporeal life support thoracic surgery", and articles were selected according to defined criteria. Key content and findings: To support lung function during thoracic surgery, the most efficient and popular variety of ECLS is venovenous extracorporeal membrane oxygenation. Lung resection on a single lung after pneumonectomy, surgery in a patient with severe hypercapnia and/or low respiratory reserve, carinal and airway surgery, and severe thoracic trauma are the main examples of situations where ECLS may be the solution to provide a safe surgical environment in patients who cannot tolerate single lung ventilation. Multidisciplinarity, selection of patients and careful surgical planning are cornerstones in defining the situations that may benefit from ECLS support. Conclusions: Knowledge on techniques of ECLS are essential for every thoracic surgeon. Although rarely used, these techniques of cardiorespiratory support should be considered when planning complex cases with difficulties in ventilation and emergent situations.
- Lobar Lung Transplantation: A Single-Center 10-Year ExperiencePublication . Cruz, Z; Neri, F; Roxo, M; Figueiredo, C; Moita, C; Costa, AR; Santos Silva, J; Reis, J; Maciel Barbosa, J; Calvinho, P; Semedo, LBackground: The shortage of donors for lung transplants is the main limitation of the preceding. Lobar transplantation is an alternative especially useful in patients with short stature and small thoracic cavities. The aim of this study was to perform a descriptive analysis of Portuguese patients who underwent lobar lung transplantation. Methods: A retrospective study was conducted, and patients submitted to lobar lung transplantation from January 2012 to December 2023 were evaluated. A descriptive analysis was made, including demographic data, lung diseases, waiting list dynamics, pre-transplant evaluations, and post-transplant outcomes. Results: Sixteen lobar transplants were performed with a predominance of female patients and a median age of 47 years. Most patients had interstitial lung disease or bronchiectasis either due to cystic fibrosis or non-cystic fibrosis. The median predicted total lung capacity (pTLC) ratio was 0.73. The median waiting list time was 6 months with 9 urgent transplants and 1 emergent lobar retransplant. Extracorporeal membrane oxygenation (ECMO) was used in pre-, intra-, and postoperative periods. Most transplanted lobes were the median lobe (ML) + right upper lobe (RUL) and left upper lobe (LUL). The median length of stay was 58 days, with complications such as PDG grade 3, bronchial tree ischemia, and concentrical stenosis of bronchial anastomosis. Six patients died in this period, 1 in the immediate postoperative period and 5 during the post-transplant hospitalization, with a median survival of 20.7 months and a 1-year and 5-year survival rate of 60%. Conclusion: Our results show a population with an increased waiting list converging in many urgent cases, with an early mortality and high primary graft dysfunction rate. Nevertheless, mid- and long-term survival are promising.

- Major Pulmonary Surgery in Patients with Compromised Lung FunctionPublication . Gonçalves Pereira, R; Branco, J; Narciso Rocha, F; Figueiredo, C; Costa, AR; Santos Silva, J; Eurico Reis, J; Calvinho, PIntroduction: The risk stratification of lung resection is fundamentally based on the results of pulmonary function tests. In patients considered to be at risk, major surgery is generally denied, opting for potentially less curative therapies. Objective: To evaluate the postoperative outcomes of major lung surgery in a group of patients deemed high risk. Methods: We performed a retrospective review of clinical records of all patients submitted to lobectomy, bilobectomy or pneumonectomy in a 3-year period in a reference Thoracic Surgery Unit. The patients were then divided in two groups: group A composed of patients with normal preoperative pulmonary function and group B which included patients with impaired lung function, defined as FEV1 and/or DLCO ≤60%. Results: A total of 234 patients were included, 181 (77.4%) in group A and 53 (22.6%) in group B. In group B, patients had more smoking habits, were more often associated with chronic obstructive pulmonary disease and were also more frequently submitted to thoracotomy. When surgery was motivated by primary lung cancer this group had a more advanced clinical stage of the disease. In the postoperative period, these patients had longer hospital stay, longer chest drainage time and greater need for oxygen therapy at home, however, no statistically significant difference was noted in morbidity or mortality. Conclusions: Major thoracic surgery can be safely performed in selected patients considered to be high risk for resection by pulmonary function tests. A potentially curative surgery should not be denied based on respiratory function tests alone.
