BACKGROUND: Neurofibromatosis type 1 is a genetic disease that affects multiple organs and systems, leading to various clinical manifestations. In Neurofibromatosis type 1, rare intrathoracic meningoceles often occur alongside bone dysplasia. These meningoceles contain cerebrospinal fluid and can be mistakenly diagnosed as \'pleural effusion\'.
METHODS: In this case report, we mistakenly identified \'cerebrospinal fluid\' as \'pleural effusion\' and proceeded with drainage. This error posed significant risks to the patient and holds valuable implications for the future diagnosis and treatment of similar patients.
CONCLUSIONS: In patients with Neurofibromatosis type 1 complicated by spinal deformity, there is a high incidence of intrathoracic meningoceles. Treatment strategies may differ based on the specific features of the lesions, and collaboration among multiple disciplines can significantly improve patient outcomes.

Thymic cavernous hemangioma (CH) as a benign lesion is extremely rare, and it is very difficult to distinguish it from other anterior mediastinal tumors on imaging.
We treated a 63-year-old woman with thymic CH that was incidentally found by chest computed tomography (CT). Contrast-enhanced chest CT described an anterior superior mediastinal mass, approximately 2.5cm in diameter, with centripetal enhancement and an increased range of enhancement in the delayed period. The tumor and thymus were completely resected by video-assisted thoracic surgery (VATS) to provide a definitive diagnosis and precise treatment. Postoperative pathology suggested that the tumor was a thymus cavernous hemangioma.
We reported an extremely uncommon case of CH in the thymus and reviewed the previously published literature. CH can occur at any age and body tissue, and there is no significant difference between males and females. Most patients are asymptomatic, often found by chest CT. Enhanced chest CT suggested that an increased area of venous enhancement at a prolonged duration may be a feature of CH. Complete surgical resection is a safe and effective method for CH in the thymus.

Thymic neoplasms are a relatively uncommon tumor, with the anterior mediastinum being the most common. Median sternotomy is the procedure of choice for the treatment of thymomas. With the advent of thoracoscopy, an increasing number of countries are adopting the right thoracic approach for the treatment of thymomas, but there are still no clear surgical standards or modalities to treat thymic carcinoma. We propose a modified subxiphoid subcostal arch thoracoscopic enlarged thymectomy to treat thymic carcinoma based on various reviews. We have also reviewed the relevant literature on the subject of evidence-based medicine. The evaluation of CD70 in combination with CD5 and CD117 or preferentially expressed antigen in melanoma in combination with CD5 and CD117 may help to diagnose thymic squamous cell carcinoma (TSCC) more accurately. The modified thoracoscopic expanded thymic resection under the costal arch of the xiphoid process is not only suitable for TSCC but also for thymic cyst, thymoma, locally invasive thymoma, and thymic carcinoma.

BACKGROUND: Pneumocephalus is a rare complication presenting in the postoperative period of a thoracoscopic operation. We report a case in which tension pneumocephalus occurred after thoracoscopic resection as well as the subsequent approach of surgical management.
METHODS: A 66-year-old man who received thoracoscopic resection to remove an intrathoracic, posterior mediastinal, dumbbell-shaped, pathology-proven neurogenic tumor. The patient then reported experiencing progressively severe headaches, especially when in an upright position. A brain computed tomography scan at a local hospital disclosed extensive pneumocephalus. Revision surgery for resection of the pseudomeningocele and repair of the cerebrospinal fluid leakage was thus arranged for the patient. During the operation, we traced the cerebrospinal fluid leakage and found that it might have derived from incomplete endoscopic clipping around the tumor stump near the dural sac at the T3 level. After that, we wrapped and sealed all the possible origins of the leakage with autologous fat, tissue glue, gelfoam, and duraseal layer by layer. The patient recovered well, and the computed tomography images showed resolution of the pneumocephalus.
CONCLUSIONS: This report and literature review indicated that the risk of developing a tension pneumocephalus cannot be ignored and should be monitored carefully after thoracoscopic tumor resection.

BACKGROUND: Pericardial rupture caused by blunt chest trauma is rare in clinical practice. Because of its atypical clinical symptoms, and because surgeons are often unfamiliar with the clinical and radiological manifestations of the injury, preoperative diagnosis is difficult; it is easily misdiagnosed and causes serious consequences.
METHODS: A 60-year-old man, previously healthy, was transported to the emergency room after falling from a great height. Upon arrival, his vital signs were stable. Electrocardiography and echocardiography were performed, and there was no sign of cardiac injury or ischemia. Chest and abdomen computerized tomography revealed pneumopericardium, hemopneumothorax, lung contusion, multiple rib fractures on the right side (Figure 1), and right scapula and clavicle fractures. He was admitted to the inpatient department for further observation after tube thoracostomy. The next day, the patient suddenly experienced rapid arrhythmia (the ventricular rate reached 150-180 beats/min) when turning onto his right side, accompanied by a blood pressure drop to 70/45 mm Hg and a chief complaint of palpitation. Thoracoscopy was performed urgently, and a large vertical tear (8 cm × 6 cm) was found in the pericardium. The defect was successfully repaired using a heart Dacron patch. His postoperative condition was uneventful without any fluctuations in vital signs, and he was transferred to the orthopedics department for further surgery on postoperative day 8.
CONCLUSIONS: Although the possibility of pericardial rupture combined with cardiac hernia is extremely low, it is one of the causes of cardiogenic shock following blunt trauma. Therefore, clinicians need to be more familiar with its characteristic manifestations and maintain a high degree of vigilance against such injuries to avoid disastrous consequences.

Tricuspid regurgitation, a common tricuspid lesion, consists of organic and functional tricuspid insufficiency (FTI). FTI is usually secondary to the valvular heart disease in left atrium. Pulmonary hypertension may result in right ventricular and tricuspid annular enlargement. This report documents our findings of tricuspid valve surgery under cardiac arrest with telescopic assistance. A 65-year-old female patient referred to our department received thoracoscope-associated tricuspid valvuloplasty. The patient exhibited a history of intermittent dyspnea and shortness of breath for 20 years, together with edema in the lower limbs for 3 months. A small incision was made, prior to an additional incision of about 3 cm in length before localization was performed at the lateral side of the 4th midclavicular line. The satellite hole was localized at the 5th midaxillary line. The operation was completed under cardiopulmonary bypass with a beating heart. Echocardiogram (ECG) analysis 10 days post-surgery indicated no clinically significant findings. Finally, the patient was discharged with slight tricuspid regurgitation .Thoracoscopy-associated heart surgery reduces postoperative pain and shortens postoperative recovery time. It is in line with the concept of rapid recovery and beauty needs. Our data confirmed that thoracoscope-assisted tricuspid valvuloplasty in an unarrested state was effective for the treatment of patients with tricuspid insufficiency, secondary to post-cardiac surgery.

BACKGROUND: To investigate the application of 3D printing technology combined with percutaneous Minimally Invasive Plate Oseoynthesis (MIPO) and thoracoscopic techniques in the treatment of long comminuted rib fractures.
METHODS: One case of multiple rib fractures with abnormal respiratory disease (including rib 3 and 4 of long comminuted fractures) due to a fall injury was selected. The 3D model of comminuted rib fracture was reconstructed and printed according to the thin-layer CT scan results. After the fracture model was restored to the normal rib anatomy, the metal plate was accurately shaped according to the 3D rib shape.
CONCLUSIONS: 3D printing technology combined with MIPO technology under thoracoscopy in the minimally invasive treatment of long-range comminuted rib fractures, greatly reduced the time and improved the accuracy of intraoperative fixation, reduced the difficulty of surgery, patient injury, and perfectly reconstructed the chest wall. Application of the 3D printing technique to make the rib model and pre-mold the metal plate combined the thoracoscopic MIPO technology provides less invasive and accurate individualized treatment for complex rib fractures.
