The patient is a 76-year-old man. His chief complaint of chest pain led to a diagnosis of pericardial effusion of unknown cause, and pericardial drainage was performed. On the 30th day, chest pain appeared again. Echocardiography revealed a pericardial fluid reaccumulation and a substantial mass in the pericardial space. Surgical drainage was performed to find the cause. A hematoma/mass was present on the epicardium. The pericardial sac was filled with hematoma. The hematoma was removed, but part of the mass infiltrated close to the anterior descending branch of the left coronary artery, and removal of that part was abandoned. The intrapericardial hematoma and epicardium were submitted to pathology leading to the diagnosis of synovial sarcoma. The patient was discharged home 14 days after surgery.

A 60-year old woman, sandwiched between two boats was brought to our hospital with severe respiratory failure. She was in pre-shock and there was extensive cutaneous emphysema from the face to abdomen. She required respirator support and bilateral chest tubes for hemopneumothorax. On the patient's 3rd hospital day, she received venovenous extracorporeal membrance oxgenation( ECMO) due to sudden ventilatory failure. The bronchofiberscopy revealed complete disruption of the left main bronchus and occlusion of the right one owing to blood clot and sputum. Because of significant destruction of the left main bronchus, we didn't attempt bronchoplasty, and performed left pneumonectomy under veno-venous (VV)-ECMO. The postoperative course was uneventful, and she was discharged after 30 days with satisfactory outcome.

Background: Intra-thoracic organ bleeding and chest wall injury following chest trauma can easily lead to life-threatening emergencies and a delay in treatment may lead to fatal outcomes. Interestingly, the optimal timing, indications, and surgical techniques have not been standardized.
Method: We retrospectively analyzed 35 patients who underwent surgical treatment for chest trauma.
Results: All patients with penetrating trauma (n=4) underwent emergency surgery for a hemothorax. There were no postoperative complications or hospital deaths. All patients with blunt trauma( n= 31) had multiple rib fractures;rib fixation was performed in 29 patients( 94%). Eight patients( 26%) had flail chest. The duration from injury to surgery averaged 7.5 days. The prognosis was generally favorable with no postoperative complications, but two patients died in the hospital due to multiple organ failure caused by high-energy trauma. Patients with flail chest or multiple organ injury had prolonged postoperative hospital stays.
Conclusions: Patients who sustain chest trauma follow various clinical courses. Appropriate timing of surgical intervention at an early stage after injury can be life saving and hasten a functional recovery.

There are two methods of end-to-side parachute anastomosis. For a quick end-to-side anastomosis, the graft and artery are placed in parallel proximity and 5 parachute stitches are performed. There are type A that moves the needle inside to outside the artery and type B that moves inside to outside the graft. Each has its advantages. In type A, complications such as dissection do not occur because the needle is always moved from the inside of the artery. Type B is faster because the first few parachute stitches are done by forehand. However, if arteriosclerosis is severe, there is a risk of dissection. Therefore, it is important to use both types appropriately.

Background: Tracheobronchial injuries resulting from blunt trauma are relatively rare among chest injuries. However, if these injuries are not managed properly, they can be fatal. The prognosis is intricately linked to the precise diagnosis and treatment. We herein report three cases of tracheobronchial trauma that required surgical intervention. Case 1:A 17-year-old male sustained injuries when his torso became entangled in heavy machinery. The diagnosis revealed a tear in the right main bronchus, which required transportation with left single- lung ventilation. The patient was treated by tracheobronchial reconstruction. Case 2:A 71-year-old male experienced trauma when his car collided with a utility pole. He was transported to the hospital after tracheal intubation due to a laceration of the tracheal membranous area. The site of the injury was closed with sutures. Case 3:A 17-year-old female who had been struck by a train suffered acute respiratory failure and was transported to the hospital after intubation. Veno-venous extracorporeal membrane oxgenation (VV-ECMO) was initiated in response to poor oxygenation. Complete rupture of the right middle bronchial trunk and laceration of the right main bronchial membrane were observed, and bronchoplasty was performed.
Conclusion: A swift and accurate diagnosis, coupled with timely and judicious therapeutic interventions, play a pivotal role in managing tracheal and bronchial injuries.

We summarized the experience of surgical stabilization of rib fractures (SSRF) at a core hospital in eastern Hiroshima, which is a primary center for tertiary emergency medical care, especially for high-energy trauma cases including chest injuries. The study focuses on patients who underwent SSRF from January 2016 to September 2023, analyzing patient characteristics, injury mechanisms, associated injuries, fracture locations, time from injury to surgery, fixation devices used, and postoperative outcomes. Our hospital primarily treats elderly patients, and falls are the most common cause of injury, followed by traffic accidents. The criteria for SSRF in our hospital were clinical manifestations of flail chest, need for lung repair, persistent pain, or improvement of thoracic deformity. We had a high rate of fixation of fractures of the 4th-10th ribs, which have a significant impact on respiratory mechanics; although KANI plates were primarily used, the introduction of MatrixRIB plates offers advantages in certain scenarios. The study also identified challenges with the KANI plate, including cases of plate dislodgement, particularly in patients with multiple fractures and severe thoracic deformities. The combination of video-assisted thoracoscopic surgery and SSRF allows for more effective rib fixation and reduces surgical wound size and muscle damage.

The patient is a 56-year-old man. He fell while playing golf and sustained a contusion on his right chest. He fell into hemorrhagic shock during surgery for a right clavicle fracture at a nearby hospital and required cardiac resuscitation. Computed tomography( CT) scan revealed left pneumothorax and right hemothorax, and a contrast-enhanced CT scan revealed a pseudoaneurysm at the brachiocephalic artery origin. He underwent surgery three weeks later. Surgery was performed through a median sternotomy and partial arch replacement (zone 2) with antegrade cerebral perfusion under moderate hypothermia. He was discharged on postoperative day 10 without significant complications.

Acute rupture of the chordae tendineae of the mitral valve could lead to severe mitral regurgitation and circulatory collapse in infants. Mitral valve replacement may be often challenging because of the valve-annulus size mismatch in small infants when mitral valve repair cannot be accomplished. We present an infant with acute massive rupture of the chordae tendineae of the mitral valve who successfully underwent supra-annular mitral valve replacement using the short composite valve of an expanded polytetrafluoroethylene( ePTFE) graft and a mechanical valve. His mechanical valve has been functioning without complications such as thrombosis and pulmonary venous obstruction for 20 months after surgery. This technique could be helpful even infants with acute rupture of the chordae tendineae of the mitral valve whose left atrium may not be dilated.

A 61-year-old woman was referred for further evaluation of an intracystic nodule in her left upper lung. Computed tomography( CT) showed a 15 mm nodule in a pulmonary cyst adjacent to aortic arch and mediastinum. Fluorodeoxyglucose-positron emission tomography (FDG-PET)-CT showed little uptake of FDG in the lesion. No abnormality was found in the bronchoscopy findings. On imaging findings, the possibility of pulmonary aspergilloma was considered, but the serological findings were inconsistent, and surgical resection of the lesion was performed for both diagnosis and treatment. The final pathohistological diagnosis was well differentiated liposarcoma. No adjuvant therapy was performed and the patient has been well without recurrence for 2 years after the surgery. We report a rare case of well differentiated liposarcoma of a lung mimicking pulmonary aspergilloma.

Formation of a pseudoaneurysm due to blood leakage from the anastomotic site of the vascular graft in large-diameter vessels is often seen, but formation of a pseudoaneurysm from the non-anastomotic site is extremely rare. A 68-year-old woman presented with a history of double valve replacement for combined valvular disease at 37 years old and hemiarch replacement for thoracic aortic dilatation at 65 years old. She visited the emergency room with a 2-week history of chest pain. Contrast-enhanced computed tomography (CT) revealed a 5-cm-diameter pseudoaneurysm and extravasation from the ascending aorta, so emergency surgery was performed. Around the ascending aorta area, we confirmed bleeding from a 5-mm dehiscence in the non-anastomotic part of the graft prosthesis, so hemostasis was performed with a cross-stitch mattress suture over a felt strip. Initially, the cause of the pseudoaneurysm was unknown, but re-examination of CT images from after the previous hemiarch replacement confirmed contact between the sternal wire and graft prosthesis. The wire was thus considered to have caused damage and bleeding. The patient was discharged from the hospital with a good postoperative course and is being followed-up in the outpatient department.
