Pneumonectomy following penetrating trauma with ECMO as postoperative support: case report - (Lung trauma and ECMO).

BACKGROUND: Penetrating thoracic injuries have a significant risk of morbi-mortality. Despite the advancements in damage control methods, a subset of patients with severe pulmonary vascular lesions and bronchial injuries persists. In some of these cases, post-traumatic pneumonectomy is required, and perioperative extracorporeal membrane oxygenation (ECMO) support may be required due to right ventricular failure and respiratory failure. CASE DESCRIPTION: A male was brought to the emergency department (ED) with a penetrating thoracic injury, presenting with massive right hemothorax and active bleeding that required ligation of the right pulmonary hilum to control the bleeding. Subsequently, he developed right ventricular dysfunction and ARDS, necessitating a dynamic hybrid ECMO configuration to support his condition and facilitate recovery. CONCLUSIONS: Penetrating thoracic injuries with severe pulmonary vascular lesions may need pneumonectomy to control bleeding. ECMO support reduces the associated mortality by decreasing the complications rate. A multidisciplinary team is essential to achieve good outcomes in severe compromised patients.

Delayed hemothorax following blunt thoracic trauma: a case report.

BACKGROUND: Late hemothorax is a rare complication of blunt chest trauma. The longest reported time interval between the traumatic event and the development of hemothorax is 44 days. CASE PRESENTATION: An elderly patient with right-sided rib fractures from chest trauma, managed initially with closed thoracostomy, presented with a delayed hemothorax that occurred 60 days after initial management, necessitating conservative and then surgical intervention due to the patient's frail condition and associated complications. CONCLUSIONS: This case emphasizes the clinical challenge and significance of delayed hemothorax in chest trauma, highlighting the need for vigilance and potential surgical correction in complex presentations, especially in the elderly.

Cardiac Sympathetic Denervation as a Treatment for Ventricular Arrhythmias Refractory to Conventional Treatment: A Case Series.

Background: Ventricular arrhythmias are a leading cause of sudden death. The objective of this study was to characterise the results of patients with ventricular arrhythmias refractory to standard medical management, undergoing Video-assisted thoracoscopic cardiac sympathetic denervation (VAT-CSD) during 2012-2022 in Cali, Colombia. Methods: This was an observational retrospective study, using the Institutional General Thoracic Surgery Database for patient identification and retrospectively reviewing the clinical charts for data description and analysis. Results: Clinical records of 19 patients who underwent VAT-CSD for ventricular arrhythmia were analysed. The patients were predominantly male (73.7%) with an mean age of 62 years. Ischaemic heart disease was the main underlying condition (52.6%); all individuals had a diagnosis of heart failure, with comorbidities such as hypertension (63.1%), acute MI (57.8%) and diabetes (26.3%) also present. The procedure was performed bilaterally in 89.4% of cases and was successful with minimal perioperative complications. Postoperative follow-up showed improvement in symptoms, including a significant reduction in the number of ICD shocks and emergency department visits. Conclusion: VAT-CSD is a viable, safe and palliative therapeutic option for patients with ventricular arrhythmias who have not responded to conventional treatments, achieving a significant decrease in symptoms with low mortality and perioperative complications.

Surgical stabilization of rib fractures under extracorporeal membrane oxygenation: A case report.

A 47-year-old male patient was referred to a level 1 trauma center with refractory acute respiratory distress syndrome, bilateral lung contusions, and flail chest after initial management for injuries sustained 5 days prior from an 8-m fall from a tower crane. Surgical stabilization of the rib fractures was achieved under extracorporeal membrane oxygenation support, with successful decannulation 4 days after surgery. The patient was discharged after 42 days and following multidisciplinary interventions. Use of extracorporeal membrane oxygenation support in blunt chest trauma patients presents a valuable opportunity as it may enable earlier surgical intervention and reduce in-hospital complications.

CT-guided harpoon marking a ground-glass infiltrate: A case report.

Physicians are facing a growing challenge in characterizing suspicious pulmonary lesions through biopsy. Video thoracoscopic surgery is crucial for conducting surgical biopsies of these nodules. However, accurately identifying small pulmonary nodules, tiny, subsolid, and deep ones, remains a significant challenge due to the absence of digital palpation. One proposed technique for localization involves using a harpoon, initially designed for mammary nodules but also applied to pulmonary nodules. In cases involving solitary pulmonary nodules, histologic characterization is often necessary also accurate descriptions through computed tomography and the patient's clinical and epidemiologic context allow for a presumptive diagnosis. In this case, during an abdominal CT scan, a 49-year-old female patient was serendipitously found to have a ground-glass infiltrate in the anteromedial segment of the lower lobe of her left lung. Despite presenting with normal lung auscultation on physical examination, the increasing prevalence of subsolid lung nodules, combined with the contemporary era of minimally invasive surgery, prompted the medical team to employ CT-guided harpoon marking for precise lesion localization. Subsequent pathology analysis confirmed the presence of lepidic pattern adenocarcinoma. This case underscores the efficacy of the CT-guided harpoon marking approach, which significantly enhances surgical precision. Such precision is paramount in formulating individualized treatment strategies and follow-up plans for patients with similar clinical presentations.

Cardiorespiratory arrest during and after nuss procedure: case report.

BACKGROUND: Pectum excavatum is a congenital thoracic alteration that can present important physiological alterations depending on the severity of the case. The Nuss procedure is a minimally invasive technique for managing chest wall deformity, in which there is a risk of perioperative complications. CASE PRESENTATION: This article presents the case of a 16-year-old patient who underwent placement of a Nuss bar and suffered intraoperative and postoperative cardiorespiratory arrest. CONCLUSIONS: it is important to consider the possible early and late complications scenarios as well as their treatment in patients with pectum excavatum scheduled for a Nuss procedure.
