Re-Expansion Pulmonary Edema Following Minimally Invasive Cardiac Surgery: A Case Report.

ABSTRACT: Re-expansion pulmonary edema (RPE) is a rare complication of minimally invasive cardiac surgery (MICS). We present a case of RPE following atrial septal defect (ASD) closure using a thoracotomy approach and cardiopulmonary bypass (CPB). REP contributes to significant morbidity and extends the length of stays in the intensive care unit. Understanding the pathophysiology and risk factors of RPE allows us to prevent or minimize the incidence.

Analysis of the therapeutic effect of right mid-axillary approach in the surgical treatment of ASD and VSD in children.

BACKGROUND: To compare the therapeutic effects of right vertical infra-axillary thoracotomy (RVIAT) and Standard Median Sternotomy (SMS) in the repair of atrial septal defect (ASD) and ventricular septal defect (VSD), and to evaluate the safety and effectiveness of right subaxillary incision technique in the surgical treatment of common congenital heart disease (CHD) in children. METHODS: Data of children diagnosed with ASD repair or VSD repair at our center from September 2019 to September 2022 were collected. Based on propensity score matching, 214 children (107 in the RVIAT group and 107 in the SMS group) who completed ASD repair surgery and 242 children (121 in the RVIAT group and 121 in the SMS group) who completed VSD repair surgery were selected for the study. The perioperative and follow-up data of the two surgical approaches were compared to evaluate clinical efficacy. RESULTS: There was no statistically significant difference (p > 0.05) between the two surgical approaches in terms of surgical time, aortic occlusion time, total amount of ultrafiltration fluid, ICU stay time, and hospital stay; The intraoperative blood loss and total postoperative drainage fluid in the RVIAT group were lower than those in the SMS group (p < 0.05); The incidence of postoperative thoracic deformities in the SMS group is higher than that in the RVIAT group. CONCLUSION: The safety and effectiveness of the two approaches are similar, but RVIAT has less intraoperative bleeding, less postoperative drainage fluid and tube time, and better concealment and cosmetic effects, which is worthy of further clinical promotion and application.

[Redo Coronary Artery Bypass Grafting Performed via Left Thoracotomy].

Eight patients underwent coronary artery bypass grafting( CABG) by left thoracotomy approach to the left coronary artery territory after CABG. The left subclavian artery was selected as an inflow anastomosis site, and the greater saphenous vein was used as a graft. The average operative time was 187 minutes, and the hospital stay was 12.2 days. Off-pump CABG was complete in all patients. There were no cases of mortality during hospitalization, and grafts were patent in the confirmed cases. We believe that the left thoracotomy approach avoids problems such as injury of the patent graft due to redo sternotomy, and reduces the mortality and complication rate.

Open thoracotomy versus VATS versus RATS for segmentectomy: a systematic review & Bayesian network meta-analysis.

BACKGROUND: Recent trials suggest that more conservative resections such as segmentectomy are non-inferior to more radical approaches. Most segmentectomy can be safely performed using video-assisted thoracoscopic surgery (VATS). The clinical benefits of robotic-assisted thoracoscopic surgery (RATS) remain unclear. We aimed to perform a systematic review evaluating the outcome of open thoracotomy, VATS, and RATS for segmentectomy. METHODS: A systematic database search was conducted of original articles exploring the outcome of open versus VATS versus RATS segmentectomy in PubMed, EMBASE and SCOPUS. The primary outcome was 30-day mortality. Secondary outcomes were hospital readmission, air leak, and post-operative pneumonia respectively. RESULTS: 11 studies were included with a total patient sample size of 7280. There were no differences between the three approaches in terms of 30-day mortality, hospital readmission, air leak, and post-operative pneumonia. CONCLUSION: There are no significant differences between the three approaches in the clinical outcomes measured. While our analysis demonstrates the potential benefits of RATS, it is important to note that the steep learning curve associated with this technique may impact its wider adoption and efficacy in the community. Further randomised control studies are required to compare the short and long terms results of VATS and RATS approaches.

Evaluating VATS versus Open Surgery for Non-Small Cell Lung Cancer: A 5-year Retrospective Study.

BACKGROUND AND OBJECTIVES: The efficacy and safety of video-assisted thoracoscopic surgery (VATS) versus open thoracotomy in the treatment of non-small cell lung cancer (NSCLC) were evaluated with a focus on mediastinal lymph node dissection, postoperative recovery, and longterm outcomes including survival rates and disease-free intervals. Materials and Methods: This retrospective study analyzed data from 228 NSCLC patients treated at the Institute of Oncology Bucharest from 2016 to 2022. Both VATS and open surgical approaches were compared, with variables including demographic data, comorbidities, surgical outcomes, and postoperative complications meticulously recorded. Statistical significance was assessed using chi-square and independent samples t-tests. Results: Among the findings, VATS demonstrated significantly better two-year progression-free survival rates for patients in early stages (Stages 1-3) of NSCLC compared to open surgery, with p-values 0.01 and 0.001, respectively. In contrast, no significant difference was observed in Stage 4. Furthermore, VATS resulted in shorter operative times (mean 299 vs. 347 minutes, p 0.001), less estimated blood loss (98.68 mL vs. 160.88 mL, p 0.001), reduced chest tube duration (5.78 days vs. 12.17 days, p 0.001), and decreased hospital stays (12.0 days vs. 27.7 days, p 0.001). Conclusions: VATS is associated with improved long-term disease-free survival for early-stage NSCLC and more favorable short-term surgical outcomes, highlighting its advantages over open thoracotomy. Despite its benefits, VATS did not significantly reduce postoperative complications compared to open surgery.

Extensive aortic replacement including aortic arch for a mega aorta with chronic aortic dissection via posterolateral thoracotomy.

BACKGROUND: Mega-aortic syndrome including aortic arch and descending aortic aneurysm is a challenging surgical case. Because the aorta continuously dilates, creating the distal anastomosis sites becomes an issue. Despite the developments in endovascular techniques including frozen elephant trunk, in the case of mega-aortic syndrome or mycotic aneurysm, extensive surgical repair is still a strong armamentarium. Our patient had a mega-aorta with chronic aortic dissection. Herein, we show tips regarding concurrent ascending, aortic arch, and descending aortic replacement via posterolateral thoracotomy for this relatively young patient. CASE PRESENTATION: A 46-year-old man with chronic kidney disease had chronic type A aortic dissection with an extensively dilated thoracic aorta from the distal ascending to the descending aorta measuring 63 mm in diameter and abdominal aorta measuring 50 mm. The short segment of the distal descending aorta was narrowed to 36 mm. The patient underwent a concurrent replacement of the distal ascending aorta, aortic arch, and descending aorta via a posterolateral thoracotomy. The patient was extubated on postoperative day (POD) 1 and discharged home without serious complications such as stroke, respiratory failure, or renal failure on POD 18. The 1-year follow-up computed tomography did not find issues in the anastomosis sites; however, the abdominal aorta enlarged from 50 to 58 mm. The patient underwent a thoracoabdominal aortic replacement and recovered well without any complications. CONCLUSIONS: Good exposure and meticulous organ protection methods are key to a safe concurrent replacement of the ascending, aortic arch, and descending aorta via posterolateral thoracotomy.

Intercostal Lung Hernias Presenting After Minimally Invasive Cardiac Surgery.

INTRODUCTION: With the introduction of minimally invasive cardiac surgery, more commonly cases of lung herniation are starting to appear. Acquired lung hernias are classified as postoperative, traumatic, pathologic, and spontaneous. Up to 83% of lung hernias are intercostal. Herein, we describe patients presenting with intercostal lung hernias following minimally invasive cardiac surgery at a single center in Medellín, Colombia. METHODS: We conducted a retrospective search of all patients presenting with intercostal lung hernias secondary to minimally invasive cardiac surgery at our clinic in Medellín since the beginning of our program, from 2010 to 2022. Mini-sternotomies were excluded from our study. We reviewed the incision type and other possible factors leading to intercostal lung hernia development. We also describe the approach taken for these patients. RESULTS: From 2010 up until 2022, 803 adult patients underwent minimally invasive cardiac surgeries through a mini-thoracotomy. At the time of data retrieval, nine patients presented with intercostal lung hernias at the previous incision site. Five hernias (55%) were from right 2nd intercostal parasternal mini-thoracotomies for aortic valve surgeries. Four hernias (45%) were from right 4th intercostal lateral mini-thoracotomies for mitral valve surgeries. Our preferred repair technique is a video-assisted thoracoscopic mesh approach. CONCLUSION: Minimally invasive cardiac surgical approaches are becoming more routine. Proper wound closure is critical in preventing lung hernias. Additionally, timely diagnosis and opportune hernia surgery using video-assisted thoracoscopic mesh repair can prevent further complications.

Mature Cystic Teratoma of Anterior Mediastinum in a Child: A Case Report and Literature Review.

Mediastinal mature cystic teratomas are rare benign germ cell tumors that predominantly affect children. Despite their low incidence, they present unique diagnostic and management challenges. Early recognition and appropriate surgical intervention are crucial for optimal outcomes. This case report aims to highlight the importance of prompt diagnosis and management of mediastinal mature cystic teratomas in pediatric patients. We present the case of a 10-year-old female patient who presented with persistent chest pain and dyspnea. Imaging studies, including a chest X-ray and contrast-enhanced chest CT scan, revealed a large, well-circumscribed anterior mediastinal mass with calcifications. The patient underwent a right thoracotomy, resulting in the excision of a 6 × 5 × 5 cm mature cystic teratoma. Histopathological examination confirmed the diagnosis. The patient had an uneventful recovery and was discharged in stable condition. Mediastinal mature cystic teratomas pose diagnostic challenges due to their nonspecific symptoms and heterogeneous imaging characteristics. Differential diagnosis includes other mediastinal masses containing fat and calcifications. Surgical excision is the preferred treatment, although complete removal can be challenging due to adhesions to neighboring structures. Close follow-up is necessary to monitor for recurrence and complications. Mediastinal mature cystic teratomas are rare tumors with variable clinical presentations. Early detection and surgical intervention are crucial for optimal outcomes. These tumors should be included in the list of differential diagnoses for mediastinal masses in pediatric patients.

Successful mediastinal teratoma resection in a child by assisted VATS: a case report.

BACKGROUND: Video-assisted thoracic surgery (VATS) is widely used for thoracic lesions in pediatric patients. VATS is also applied to pediatric mediastinal tumors if there is no adhesion or invasion between the tumor and adjacent neuronal and cardiovascular structures. Here, we present a pediatric case of mediastinal teratoma in which the tumor adhered to the superior vena cava, and resection was safely completed using assisted VATS, an integrated surgical approach comprising mini-thoracotomy with video assistance. CASE PRESENTATION: A 9 year-old girl presented with right shoulder pain. Chest radiography and computed tomography revealed a 5.4 × 5.1 × 5.8 cm mass in the right upper anterior mediastinum. She was presumed with a mature teratoma, and resection was performed by assisted VATS with muscle sparing axillar skin crease incision (MSASCI) for a mini-thoracotomy. The procedure was safely completed, with the patient discharged on postoperative day 5. At 1 year postoperatively, there was no recurrence with excellent motor and cosmetic results. CONCLUSIONS: The combination of MSASCI and VATS would be useful not only for mediastinal teratomas but also for other mediastinal tumors and almost all other thoracic lesions in pediatric patients.

Analysis of contributing factors and nursing interventions for postoperative agitation following general anesthesia in thoracotomy patients.

To analyze the factors influencing agitation during emergence from general anesthesia in patients undergoing thoracotomy and to explore corresponding nursing interventions to optimize the postoperative recovery process. This study included 200 patients who underwent thoracotomy with general anesthesia at our hospital between January 12, 2022, and June 1, 2023. After surgery, all patients were closely monitored in the Intensive Care Unit (ICU). Based on their agitation status during emergence from anesthesia, patients were divided into 2 groups: an observation group (87 cases with agitation) and a control group (113 cases without agitation). We performed univariate analysis and multivariate logistic regression to identify risk factors for agitation. Based on these findings, we proposed targeted nursing strategies to address the causes of agitation, prevent complications, and meet patient care needs. Univariate analysis showed significant differences between the observation and control groups regarding age, propofol dosage, duration of surgery, infusion volume, and preoperative cognitive dysfunction (P < .05). Multivariate logistic regression identified 3 key risk factors: age over 60 years, surgery duration over 2 hours, and preoperative cognitive dysfunction. Based on these findings, we developed targeted nursing strategies to reduce the incidence of agitation and promote smooth recovery. Agitation during emergence from general anesthesia in patients undergoing thoracotomy is closely related to factors such as age and surgery duration. Developing personalized nursing plans based on these factors can enhance postoperative monitoring and care, thereby reducing agitation and improving recovery quality.

Early and late outcomes of video thoracoscopic versus open approach for bronchiectasis lung resections.

OBJECTIVES: To evaluate the early and late results of surgical treatment of patients with bronchiectasis, comparing the Video-Assisted Thoracic Surgery (VATS) vs. the open thoracotomy (OT). METHODS: Observational retrospective study of patients who underwent surgery for bronchiectasis. Patients were divided into two groups according to surgical access OT/VATS. Variables collected included gender, age, preoperative symptoms, etiology, segments involved, FVC and FEV1, type of surgical resection, complications, mortality, and length of hospital stay. Late surgical results were classified as excellent, complete remission of symptoms; good, significative improvement; and poor, little/no improvement. RESULTS: 108 surgical resections (103 patients). OT group 54 patients (52.4%) vs. VATS 49 (47.6%). A high percentage of complications was observed, but no difference between the OT (29.6%) and VATS (24.5%) groups was found. Post-operative hospital stay was shorter in the VATS group (5.4 days) vs. the OT group (8.7 days (p=0.029). 75% of the patients had a late follow-up; the results were considered excellent in 71.4%, good in 26%, and poor in 2.6%. Regarding bronchiectasis distribution, an excellent percentage was obtained at 82.1% in patients with localized bronchiectasis and 47.5% with non-localized bronchiectasis, p=0.003. CONCLUSIONS: VATS leads to similar results regarding morbidity, compared to OT. However, VATS was related to shorter hospital stays, reflecting the early recovery. Late results were excellent in most patients, being better in patients with localized bronchiectasis. VATS should be considered a preferable approach for bronchiectasis lung resection whenever possible.

Introducción: El sarcoma de Ewing es un tumor maligno de alto grado con localización principalmente ósea; se han reportado aproximadamente 12% con presentación extra-esquelética. Actualmente, existen alrededor de 20 casos descritos en la literatura con origen mediastinal y 10 casos con origen pulmonar. Caso clínico: Se presenta el caso de una mujer de 25 años con un mes de disnea y dolor torácico, con el hallazgo de derrame pleural masivo y tumoración mediastinal en hemitórax derecho. Se le realiza toracotomía anterior bilateral con esternotomía transversa de Clamshell, con resección parcial que demuestra, por patología, sarcoma monomórfico de alto grado e inmunohistoquímica concluyente de sarcoma de Ewing. Conclusión: Este caso es una entidad rara y conlleva un reto diagnóstico para el clínico; sin embargo, debe sospecharse considerando la presentación clínica y radiológica del paciente, buscando incrementar la tasa de supervivencia mediante el diagnóstico y tratamiento oportuno.

Introduction: Ewing's sarcoma is a high-grade malignant tumor with mainly bony lo-calization; approximately 12% have been reported with extraskeletal presentation. Currently, there are about 20 cases described in the literature with mediastinal origin and 10 pulmonary cases. Case Report: We present the case of a 25-year-old woman with one month of dysp-nea and chest pain, with massive pleural effusion and mediastinal tumor in the right hemithorax who underwent bilateral anterior thoracotomy with Clamshell transverse sternotomy, with partial resection demonstrating, by pathology, high-grade monomorphic sarcoma and conclusive immunohistochemistry of Ewing's sarcoma. Conclusion: This case is a rare entity and involves a diagnostic challenge for the clinician; however, it should be suspected considering the clinical and radiological presentation of the patient, seeking to increase the survival rate through timely diagnosis and treatment.

Rib myelolipoma: a case report.

BACKGROUND: Myelolipoma is an uncommon benign tumor composed of mature adipose tissue and hematopoietic elements. These tumors generally affect the adrenal glands, with anomalous presentations being rare and with few cases described in the literature. Most myelolipomas are asymptomatic and discovered incidentally, either through imaging tests or at autopsies. However, depending on the location and size of the lesion, myelolipomas can cause symptoms of mass effect. This article aims to report a very rare presentation of a symptomatic primary myelolipoma affecting the ribs. CASE PRESENTATION: A 21-year-old white female patient presented with a complaint of burning chest pain over 3 months, with gradual worsening in intensity, accompanied by a progressively growing bulge in the right thoracic wall. The patient underwent thoracotomy of the fifth and sixth ribs with complete excision of the lesion with a safety margin. Thoracic wall reconstruction was performed using a polypropylene mesh. The patient had a good postoperative course and was discharged on postoperative day 3. Histopathological examination revealed a histological image consistent with myelolipoma. CONCLUSIONS: This report underscores the importance of considering a myelolipoma diagnosis for tumor masses in the ribs.

Differentiating low-risk thymomas from high-risk thymomas: preoperative radiomics nomogram based on contrast enhanced CT to minimize unnecessary invasive thoracotomy.

BACKGROUND: This study was designed to develop a combined radiomics nomogram to preoperatively predict the risk categorization of thymomas based on contrast-enhanced computed tomography (CE-CT) images. MATERIALS: The clinical and CT data of 178 patients with thymoma (100 patients with low-risk thymomas and 78 patients with high-risk thymomas) collected in our hospital from March 2018 to July 2023 were retrospectively analyzed. The patients were randomly divided into a training set (n = 125) and a validation set (n = 53) in a 7:3 ratio. Qualitative radiological features were recorded, including (a) tumor diameter, (b) location, (c) shape, (d) capsule integrity, (e) calcification, (f) necrosis, (g) fatty infiltration, (h) lymphadenopathy, and (i) enhanced CT value. Radiomics features were extracted from each CE-CT volume of interest (VOI), and the least absolute shrinkage and selection operator (LASSO) algorithm was performed to select the optimal discriminative ones. A combined radiomics nomogram was further established based on the clinical factors and radiomics scores. The differentiating efficacy was determined using receiver operating characteristic (ROC) analysis. RESULTS: Only one clinical factor (incomplete capsule) and seven radiomics features were found to be independent predictors and were used to establish the radiomics nomogram. In differentiating low-risk thymomas (types A, AB, and B1) from high-risk ones (types B2 and B3), the nomogram demonstrated better diagnostic efficacy than any single model, with the respective area under the curve (AUC), accuracy, sensitivity, and specificity of 0.974, 0.921, 0.962 and 0.900 in the training cohort, 0.960, 0.892, 0923 and 0.897 in the validation cohort, respectively. The calibration curve showed good agreement between the prediction probability and actual clinical findings. CONCLUSIONS: The nomogram incorporating clinical factors and radiomics features provides additional value in differentiating the risk categorization of thymomas, which could potentially be useful in clinical practice for planning personalized treatment strategies.

[Severe Thoracic Trauma Indications and Contraindications for Non-operative and Operative Treatment Strategies]. / Das schwere Thoraxtrauma: Indikationen und Kontraindikationen für operative und nicht operative Versorgungsstrategien.

Severe thoracic trauma can occur as a penetrating or blunt mono-injury or as part of a polytrauma. Almost half of all severely injured patients documented in the TraumaRegister DGU were diagnosed with severe chest trauma, defined according to the Abbreviated Injury Scale (AIS) as ≥ 3. In our own collective, the proportion was even higher with 60%. Emergency surgical treatment with a thoracotomy within the Trauma Resuscitation Unit or within the first hour of admission is an extremely rare intervention in Germany, accounting for 0.9% of severe thoracic injuries. The management of complex polytraumas and extensive pathophysiological reactions to the trauma, as well as knowledge about the development of secondary damage have led to the conclusion that minimally invasive procedures such as video-assisted thoracoscopy (VATS) or inserting a chest drain can resolve most severe thoracic injuries. At < 4%, penetrating injuries to the thorax are a rarity. Among blunt thoracic injuries, > 6% show an unstable thoracic wall that requires surgical reconstruction. The demographic development in Germany leads to a shift in injury pattern. Low-energy trauma results have lower incidence than higher-grade chest wall injuries with penetrating rib fractures in the pleura, lungs, peri-/myocardium and diaphragm. Sometimes this results in instability of the chest wall with severe restriction of respiratory mechanics, which leads to fulminant pneumonia and even ARDS (Acute Respiratory Distress Syndrome). With this background, surgical chest wall reconstruction has become increasingly important over the past decade. Together with the underlying strong evidence, the assessment of the extend and severity of the trauma and the degree of respiratory impairment are the basis for a structured decision on a non-surgical or surgical-reconstructive strategy, as well as the timing, type and extent of surgery. Early surgery within 72 hours can reduce morbidity (pneumonia rate, duration of intensive care and ventilation) and mortality. In the following article, evidence-based algorithms for surgical and non-operative strategies are discussed in the context on the management of severe thoracic injuries. Thus, a selective literature search was carried out for the leading publications on indications, treatment strategy and therapy recommendations for severe thoracic injury, chest wall reconstruction.

Evaluating VATS versus Open Surgery for Non-Small Cell Lung Cancer: A 5-year Retrospective Study.

BACKGROUND AND OBJECTIVES: The efficacy and safety of video-assisted thoracoscopic surgery (VATS) versus open thoracotomy in the treatment of non-small cell lung cancer (NSCLC) were evaluated with a focus on mediastinal lymph node dissection, postoperative recovery, and longterm outcomes including survival rates and disease-free intervals. Materials and Methods: This retrospective study analyzed data from 228 NSCLC patients treated at the Institute of Oncology Bucharest from 2016 to 2022. Both VATS and open surgical approaches were compared, with variables including demographic data, comorbidities, surgical outcomes, and postoperative complications meticulously recorded. Statistical significance was assessed using chi-square and independent samples t-tests. Results: Among the findings, VATS demonstrated significantly better two-year progression-free survival rates for patients in early stages (Stages 1-3) of NSCLC compared to open surgery, with p-values 0.01 and 0.001, respectively. In contrast, no significant difference was observed in Stage 4. Furthermore, VATS resulted in shorter operative times (mean 299 vs. 347 minutes, p 0.001), less estimated blood loss (98.68 mL vs. 160.88 mL, p 0.001), reduced chest tube duration (5.78 days vs. 12.17 days, p 0.001), and decreased hospital stays (12.0 days vs. 27.7 days, p 0.001). Conclusions: VATS is associated with improved long-term disease-free survival for early-stage NSCLC and more favorable short-term surgical outcomes, highlighting its advantages over open thoracotomy. Despite its benefits, VATS did not significantly reduce postoperative complications compared to open surgery.

Direct aortic TAVI via anterior right mini-thoracotomy using 32 mm myval for pure aortic regurgitation.

BACKGROUND: Aortic regurgitation with dilated annulus presents a technical challenge for conventional transcatheter aortic valve implantation (TAVI) procedures. CASE PRESENTATION: We report a case of an 84-year-old frail patient with a history of breathlessness found to have severe aortic regurgitation and moderately impaired left ventricular systolic function. The patient underwent a successful TAVI procedure using the XL-Myval 32 mm transcatheter heart valve (THV) via an anterior right mini-thoracotomy with a direct aortic approach. The patient recovered well post-operatively with good hemodynamic resolution. CONCLUSIONS: This first in human case highlights the efficacy and potential of applying innovative approaches, such as the new sizes of Myval THV and direct aortic access via anterior right mini thoracotomy, in addressing challenging anatomical variations in TAVI procedures with good outcome.

Anesthesia for an infant with congenital mediastinal mass: a case report.

BACKGROUND: Giant anterior mediastinal masses in infants are one of the most challenging cases faced in pediatric anesthesia practice. They can pose unique challenges for resection such as cardiovascular collapse on induction of anesthesia and injury to surrounding structures that maybe compressed or displaced. Principles that must be followed and kept in mind during removal of giant mediastinal mass include appropriate diagnostic imaging to define mass extent, airway control during induction, a multidisciplinary team approach including cardiothoracic for sternotomy, cannulation to institute cardiopulmonary bypass, otolaryngology for rigid bronchoscopy, preservation of neurovascular structure, and complete resection whenever possible. Our patient had a mass that weighed twice his whole body weight. CASE PRESENTATION: Here we present a 3-month-old Middle Eastern infant weighing 3.2 kg with a large congenital teratoma who presented to the emergency room with cyanosis and respiratory distress. During his hospital course, he underwent three procedures, two of them under light-to-moderate sedation: a diagnostic computer tomography scan followed by mass content drainage by interventional radiology (Figs. 1, 2). On the third day, he had a thoracotomy with complete tumor resection under general anesthesia with the help of an epidural for pain control (Fig. 3). The resected tumor weighed 2.5 kg, which was equal to twice the patient's total body weight (Fig. 4). After the surgery, he was extubated in the operating room and discharged home 3 days later. Fig. 1 Anterior-posterior chest x-ray showing the anterior mediastinal mass (AMM) Fig. 2 Cross-section computed tomography (CT) showing large anterior mediastinal mass (AMM) Fig. 3 Gross anatomy of the tumor before resection Fig. 4 Gross anatomy of the removed tumor CONCLUSION: Anterior mediastinal mass patients can be challenging for the anesthesiologist. They need meticulous thorough perioperative assessment to determine the extent of compression on major intramediastinal structures and to predict the complications. Planning by multidisciplinary team and discussion with the family is important. These types of cases should be preferably operated on by an experienced team in a well-equipped operation room in tertiary care institutes.

Successful minimally invasive treatment of a young patient with a dislocated Amplatzer Septal Occluder.

In this case report, we illustrate the minimally invasive endoscopic repair of an atrial septal defect via a right minithoracotomy in a young patient with a dislocated Amplatzer Septal Occluder.

Intraoperative surgical complications of open surgery for congenital diaphragmatic hernia: a multicenter, observational study in Japan.

PURPOSE: This study aimed to clarify surgical complications associated with open surgery for congenital diaphragmatic hernia (CDH). METHODS: We performed an exploratory data analysis of the clinical characteristics of surgical complications of neonates with CDH who underwent laparotomy or thoracotomy between 2006 and 2021. Data of these patients were obtained from the database of the Japanese CDH Study Group. RESULTS: Among 1,111 neonates with left or right CDH, 852 underwent open surgery (laparotomy or thoracotomy). Of these 852 neonates, 51 had the following surgical complications: organ injury (n = 48; 6% of open surgeries); circulatory failure caused by changes in the organ location (n = 2); and skin burns (n = 1). Injured organs included the spleen (n = 30; 62% of organ injuries), liver (n = 7), lungs (n = 4), intestine (n = 4), adrenal gland (n = 2), and thoracic wall (n = 2). Fourteen of the patients who experienced organ injury required a blood transfusion (2% of open surgeries). The adjusted odds ratio of splenic injury for patients with non-direct closure of the diaphragm was 2.2 (95% confidence interval, 1.1-4.9). CONCLUSION: Of the patients who underwent open surgery for CDH, 2% experienced organ injury that required a blood transfusion. Non-direct closure of the diaphragmatic defect was a risk factor for splenic injury.
