[Outcomes of Surgical Treatment for Chest Trauma].

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.

Thoracic Lavage for Traumatic Hemothorax.

This Surgical Innovation discusses thoracic lavage for traumatic hemothorax.

Right ventricular lead perforation with iatrogenic injury to an intercostal artery causing haemothorax after pacemaker implant.

A woman in her 80s experienced a life-threatening complication of pacemaker implant consisting of subacute right ventricular lead perforation causing iatrogenic injury to an intercostal artery, resulting in a large haemothorax. A CT scan confirmed active bleeding from the fourth intercostal artery. The patient underwent cardiothoracic surgery via a median sternotomy approach, during which the source of the bleeding was sealed, a new epicardial lead was positioned, and the original lead was extracted. This case emphasises the potentially severe consequences of pacemaker lead perforation and secondary injury to adjacent structures. It underscores the importance of early recognition and timely intervention, preferably in a tertiary specialist unit equipped for cardiothoracic surgery and confirms the value of pacemaker interrogation and CT scans for diagnosis.

An audit of traumatic haemothoraces in a regional hospital in KwaZulu-Natal, South Africa.

BACKGROUND: Haemothorax occurs in approximately 60% of all thoracic and polytrauma cases and is responsible for 15-30% of all trauma mortalities. Penetrating injuries to the thorax are a common presentation in South African hospitals. This study aims to audit the traumatic haemothoraces and their outcomes in regional hospitals in Durban, KwaZulu-Natal, South Africa. METHODS: In this study, patient characteristics were grouped as either continuous or categorical variables. Continuous variables, such as age were summarised as means (with standard deviations) or medians (interquartile range [IQR]), as appropriate. Categorical variables such as sex were summarised as proportions. Fisher's exact test was used to compare proportions. All analyses were performed using the Statistical Package for Social Sciences. RESULTS: A total of 118 patients were included comprising 110 (93%) males and eight (7%) females, with an average age of 29.7 years. Stab-chest was the most frequent mechanism of injury (76; 64.4%), followed by gunshot wound (GSW)- chest (27; 22.9%) and isolated blunt chest trauma (9; 7.6%). Other mechanisms of injury were stab-neck (3; 2.5%), stab-shoulder (2; 1.7%) and blunt chest trauma in the context of polytrauma (1; 0.8%). The most frequent type of injury was penetrating (108; 91.5%), with only 10 (8.5%) cases of blunt injury. This study found that there was a statistically significant association between patient age groups and type of injury. CONCLUSION: Haemothorax is a common sequela of chest trauma. Retained haemothorax (RH) results in worsened patient outcomes including increased hospital length of stay (LOS). This study points to the need for auditing of proper intercostal chest drain (ICD) positioning, which is crucial for the successful drainage of haemothorax.

Child abuse with multiple sharp foreign bodies penetrating the chest wall causing hemothorax and cardiac tamponade in two separate occasions: Case report.

We present a case of repeated child abuse causing left-sided hemothorax and cardiac tamponade on two separate occasions. A 14-year-old cerebral palsy male presented with left-sided hemothorax and multiple metallic foreign bodies in the chest wall managed by small limited incision, removal of the foreign bodies and chest tube. One week later, he came to our emergency department (ER) with multiple chest wall foreign bodies and tamponade managed by median sternotomy, removal of the foreign bodies, one of them was in the LAD. He had a smooth postoperative course and the case is under investigation.

Thoracic aortic dissection presenting with bilateral haemothoraces: a potentially missed diagnosis.

Thoracic aortic dissection is a life-threatening diagnosis, which should not be missed. We present a case in which a patient who presented to the emergency department with chest pain was assessed and referred for admission for treatment of pneumonia, due to misinterpretation of a chest radiograph finding. The patient was re-reviewed and subsequently underwent further investigation, which confirmed aortic dissection. She underwent emergency thoracic endovascular aortic graft repair with stent graft insertion. This case demonstrates haemothorax as an uncommon complication of aortic dissection.

Predictors of initial management failure in traumatic hemothorax: A prospective multicenter cohort analysis.

BACKGROUND: Traumatic hemothorax is common, and management failure leads to worse outcomes. We sought to determine predictive factors and understand the role of trauma center performance in hemothorax management failure. METHODS: We prospectively examined initial hemothorax management (observation, pleural drainage, surgery) and failure requiring secondary intervention in 17 trauma centers. We defined hemothorax management failure requiring secondary intervention as thrombolytic administration, tube thoracostomy, image-guided drainage, or surgery after failure of the initial management strategy at the discretion of the treating trauma surgeon. Patient-level predictors of hemothorax management failure requiring secondary intervention were identified for 2 subgroups: initial observation and immediate pleural drainage. Trauma centers were divided into quartiles by hemothorax management failure requiring secondary intervention rate and hierarchical logistic regression quantified variation. RESULTS: Of 995 hemothoraces in 967 patients, 186 (19%) developed hemothorax management failure requiring secondary intervention. The frequency of hemothorax management failure requiring secondary intervention increased from observation to pleural drainage to surgical intervention (12%, 22%, and 35%, respectively). The number of ribs fractured (odds ratio 1.12 per fracture; 95% confidence interval 1.00-1.26) and pulmonary contusion (odds ratio 2.25, 95% confidence interval 1.03-4.91) predicted hemothorax management failure requiring secondary intervention in the observation subgroup, whereas chest injury severity (odds ratio 1.58; 95% confidence interval 1.17-2.12) and initial hemothorax volume evacuated (odds ratio 1.10 per 100 mL; 95% confidence interval 1.05-1.16) predicted hemothorax management failure requiring secondary intervention after pleural drainage. After adjusting for patient characteristics in the logistic regression model for hemothorax management failure requiring secondary intervention, patients treated at high hemothorax management failure requiring secondary intervention trauma centers were 6 times more likely to undergo an intervention after initial hemothorax management failure than patients treated in low hemothorax management failure requiring secondary intervention trauma centers (odds ratio 6.18, 95% confidence interval 3.41-11.21). CONCLUSION: Failure of initial management of traumatic hemothorax is common and highly variable across trauma centers. Assessing patient selection for a given management strategy and center-level practices represent opportunities to improve outcomes from traumatic hemothorax.

Evidence-Based Pearls: Chest Trauma.

The challenge in caring for patients who sustain traumatic chest injuries centers on their complex needs from high acuity and the potential for multisystem effects and complications. Hemorrhage and respiratory compromise are common sequela of thoracic trauma. Patients must be resuscitated and their injuries managed with the primary goals of restoring cardiopulmonary structural integrity and preventing complications. There are evolving strategies for the management of the thoracic trauma victim including damage control resuscitation and surgery, endovascular repairs, and assessments implementing severity scores to aid in planning interventions.

Ruptured mycotic aneurysm of intercostal arteries associated with vertebral osteomyelitis: a case report.

BACKGROUND: Here, we report a rare case of massive hemothorax caused by rupture of an intercostal artery pseudoaneurysm associated with pyogenic spondylodiscitis, which was successfully treated with endovascular intervention. CASE PRESENTATION: A 49-year-old man with schizophrenia, idiopathic esophageal rupture, postoperative mediastinal abscess, and pyothorax, diagnosed with pyogenic spondylodiscitis caused by methicillin-resistant Staphylococcus aureus. Magnetic resonance imaging and computed tomography (CT) showed extensive vertebral body destruction. The patient underwent a two-stage operation: anterior vertebral debridement and fixation with iliac bone graft and 10 days after first surgery, posterior fixation with instrumentation. Seven days after second surgery, the patient's right chest pain increased, his blood pressure dropped, and he had shock. Chest X-ray showed massive hemothorax in the right lung. Chest CT and subsequent intercostal arteriography showed a pseudoaneurysm in the right T8 intercostal artery and active contrast extravasation from it. This seemed ruptured mycotic aneurysms involving intercostal vessels. These vessels were successfully embolized using micro-coils. Then, the patient completed the prescribed antimicrobial therapy in the hospital without any complications. CONCLUSIONS: Intercostal artery aneurysms are rare vascular abnormalities. They have the risk of rupture and may sometimes cause hemothorax and can be potentially life-threatening. Ruptured intercostal artery pseudoaneurysms are a good indication of endovascular intervention, and prompt embolization saved the life of the patient in this case report. This case report highlights the possibility of a ruptured intercostal mycotic aneurysm in patients with pyogenic spondylodiscitis and reminds physicians to be alert of this rare but potentially fatal complication.

Delayed Arterial Bleed After Pulmonary Lobectomy.

BACKGROUND: Postlobectomy hemorrhage is rare. The majority of the bleeding happens early after surgery, with the median time to reoperation being 17 hours. CASE REPORT: A 64-year-old man with a lung nodule underwent video-assisted thoracic surgery right upper lobectomy 3 weeks prior and presented to the Emergency Department (ED) with acute-onset chest pain and shortness of breath in the setting of delayed hemothorax from acute intercostal artery bleeding. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The vast majority of the patients presenting to the ED with a hemothorax have a known history of trauma. It is important for emergency physicians to consider and recognize hemothorax in nontraumatic patients, especially those who underwent recent lung surgeries. Delayed postoperative hemorrhage is rare but possible, and can be life threatening.

Massive hemothorax secondary to internal jugular vein central venous catheter placement in a patient undergoing spinal surgery complicated by chest trauma: a case report.

BACKGROUND: Placement of a central venous catheter (CVC) is a common procedure for spinal surgery and is relatively safe under ultrasound guidance. CASE PRESENTATION: We report the case of a 56-year-old female who underwent ultrasound-guided placement of an internal jugular vein CVC for fluid replacement during spinal surgery for thoracic vertebral burst compression fracture and multiple rib fractures as a result of a high-altitude fall injury. Hemothorax developed intraoperatively. During a thoracotomy, the tip of the CVC was found within the chest cavity. The presence of chest trauma may impact on clinician's appreciation of the potential complications of internal jugular vein CVC placement. CONCLUSION: The present case demonstrates the need for clinical awareness of the potential complications of CVC placement in patients with chest trauma and the need for adequate training in this technique.

Reintervention Rate After Pigtail Catheter Insertion Compared to Surgical Chest Tubes.

BACKGROUND: Prior studies suggest similar efficacy between large-bore chest tube (CT) placement and small-bore pigtail catheter (PC) placement for the treatment of pleural space processes. This study examined reintervention rates of CT and PC in patients with pneumothorax, hemothorax, and pleural effusion. METHODS: This retrospective study examined patients from September 2015 through December 2020. Patients were identified using ICD codes for pneumothorax, hemothorax, or pleural effusion. Use of a pigtail catheter (≤14Fr) or surgical chest tube (≥20Fr) was noted. The primary outcome was overall reintervention rate within 30 days of tube insertion. Patients who died with a pleural drainage catheter in place, unrelated to complications from chest tube placement, were excluded. RESULTS: There were 1032 total patients in the study: 706 CT patients and 326 PC patients. The PC group was older with more comorbidities and more likely to have effusion as the indication for pleural drainage. Patients with PC were 2.35 times more likely to have the tube replaced or repositioned (P < .0001), 1.77 times more likely to require any reintervention (P = .001) and 2.09 times more likely to remain in the hospital >14 days (P < .0001) compared to patients with CT. CONCLUSION: PCs have a significantly higher reintervention rate compared to CT for the treatment of pneumothorax, hemothorax, and pleural effusion. Although PC are believed to cause less pain and tissue trauma, they do not necessarily drain the pleural space as well as CT. Decisions on which method of draining the chest should be made on a case-by-case basis.

[Occult and Retained Haemothorax - Recommendations of the Interdisciplinary Thoracic Trauma Task Group of the German Trauma Society (DGU - Section NIS) and the German Society for Thoracic Surgery (DGT)]. / Okkulter und residueller Hämatothorax nach Thoraxtrauma ­ Empfehlungen der interdisziplinären Arbeitsgruppe Thoraxtrauma der Sektion NIS der Deutschen Gesellschaft für Unfallchirurgie (DGU) und der Deutschen Gesellschaft für Thoraxchirurgie (DGT).

The management of occult and retained haemothorax is challenging for all involved in the care of polytrauma patients in terms of diagnosis and treatment. The focus of decision making is preventing sequelae such as pleural empyema and avoiding a trapped lung. An interdisciplinary task force of the German Society for Thoracic Surgery (DGT) and the German Trauma Society (DGU) on thoracic trauma offers recommendations for post-trauma care of patients with occult and/or retained haemothorax, as based on a comprehensive literature review.

Could video-assisted thoracoscopic surgery be feasible for blunt trauma patients with massive haemothorax?

INTRODUCTION: The study reviewed the experience of video-assisted thoracoscopic surgery (VATS) for the treatment of massive haemothorax (MHT). MATERIALS AND METHODS: All adult patients who sustained blunt trauma with a diagnosis of traumatic haemothorax or pneumothorax (ICD9 860; ICD10 S27.0-2), injury to the heart and lungs (ICD9 861; ICD10 S26, S27.3-9), and injury to the blood vessels of the thorax (ICD9 901; ICD10 S25) were queried from the trauma registry between 2014 and 2018. Patients who had chest tube drainage amounts meeting the criteria for MHT and who underwent subsequent operations were eligible for analyses. The patients were divided into VATS or thoracotomy groups based on the surgical modalities. Descriptions and analyses of the two groups were made. RESULTS: Thirty-eight patients were enroled in the study, including 8 females (21%) and 30 males. The median age was 47.0 (first quartile (Q1) 25.5 and third quartile (Q3) 59.3) years. Twenty-three patients were in the VATS group, six (26%) of whom were converted to thoracotomy. There were no obvious differences in age, sex, pulse rate, or systolic pressure on arrival to the ED or after resuscitation between the two groups. The laboratory data were worse amongst the thoracotomy group, especially the arterial blood gas analysis (ABG) results: pH 7.2 (7.1, 7.3) vs. 7.4 (7.2, 7.4); HCO3 14.6 (12.4, 18.7) vs. 19.7 (16.1, 23.9) mEq/L; base excess (BE) -12.6 (-15.8, -7.8) vs. -5.2 (-11.1, -0.9) mEq/L. The PaO2/FiO2 ratio was lower in the thoracotomy group (91.4 (68.5, 193.3) vs. 245.3 (95.7, 398.0) mmHg). The thoracotomy group had coagulopathy (INR 1.6 (1.2, 1.9) vs. 1.3 (1.1, 1.4)) and required more blood transfusions (WB and PRBC 36.0 (16.0, 48.0) vs. 12.0 (4.0, 24.0) units; FFP 20.0 (6.0, 50.0) vs. 6.0 (2.0, 20.0) unit). No factors associated with VATS conversion to thoracotomy could be identified. CONCLUSIONS: VATS could be applied to selected blunt trauma patients with MHT. The major differences between the VATS and thoracotomy groups were coagulopathy, acidosis, PaO2/FiO2 ratio < 200 mmHg, or a persistent need for blood transfusion.

Is VATS approach suitable in re-operations for postoperative hemothorax after pulmonary resection? Data analysis in a big volume thoracic center.

OBJECTIVE: This study explored the safety and of feasibility of video-assisted thoracoscopy (VATS) in re-operations for post-operative hemothorax. METHODS: The clinical data of patients underwent re-operations due to post-operative hemothorax after pulmonary resection in Shanghai Pulmonary Hospital from 2006 to 2018 were retrospectively analysed. The incidence of re-operations were analyzed. The mortality and morbidity were compared between thoracotomy and thoracoscopic procedure for re-exploration. RESULTS: A total of 114 patients were included. The annual incidence rate ranged from 0.21 to 0.54%; the perioperative mortality was 2.6%; there were 114 cases of re-operations for hemothorax after 2012, including 62 cases in thoracoscopy group and 52 cases in open group. The durations of chest-tube drainage (7.2 ± 3.9 days vs 10.9 ± 12.0 days, P = 0.001) and length of stay in hospital (13.7 ± 6.7 days vs 18.9 ± 10.6 days, P = 0.002) in the thoracoscopic group were shorter than those in the open group. The thoracoscopic group had fewer post-operative complications as well (P = 0.023). Meanwhile, post-operative complications in the delayed group were significantly higher than those in the non-delayed group, with a longer length of hospital stay and higher hospitalization costs. CONCLUSION: Complete VATS is safe and feasible for re-operation due to post-operative hemothorax and can be an alternative to thoracotomy. Delayed re-operations are associated with more post-operative complications and higher costs.

Modern treatment of massive hemothorax / A masszív haemothorax modern kezelése

Introduction and objective: Hemothorax is an umbrella term for pathologies with an extremely wide range of etiology and severity. Most commonly it is of tramuatic origin, frequently iatrogenic (intervention, blood coagulation altering therapy) and rarely unknown. Depending on the cause, volume, and dynamics, it requires a patient-adapted treatment determined by access to certain therapeutical methods. We aim to provide a practical overview of these. Methods: Retrospective analysis of patients treated for haemothorax at the Thoracic Surgery Department of Borsod-Abaúj-Zemplén County Teaching Hospital in the period 1 January 2017­31 December 2021 has been performed. We used the hospital's database to collect data. In this paper, we analyze the cause of hemothorax, method of treatment, the efficacy of chosen therapeutic modality, duration of hospital stay, complication rate, 30-day survival. Results: 77 patients were treated with hemothorax, 57 male, 20 female patients. Average age was 53,4 (23­90, SD:14,9) years. Surgery was performed in 31 cases, with 10 cases needing reintervention. In 7 cases, multimodal approach was chosen, with chest wall stabilization. Average hospital stay: 14 (2­79) days. 30-day survival: 95%. Discussion: Thoracic drainage is our first therapeutic choice. The methods used in the treatment of hemothorax in our practice have been extended with the use of digital subtraction angiography (DSA), which yields immediate and effective bleeding control. We performed video-assisted thoracoscopic surgery (VATS) in increasing numbers. Conclusions: As long as the intensity of bleeding and patient's general status allows it, after drainage, the first therapeutic option ­ when accessible ­ should be DSA bleeding control. In cases which do not resolve after drainage, VATS evacuation of hematoma is a safe method used in the treatment of hemothorax. In the past 5 years, we used thoracoscopy in increasing numbers while treating this entity. Based on our results and the literature, we can safely state that the use of thoracoscopy in the treatment of hemothorax is a safe and reliable option in eligible patients, and the results are comparable with those treated by thoracotomy.

Hemothorax caused by costal exostosis injuring diaphragm: a case report and literature review.

BACKGROUND: Osteochondromas, also known as exostoses, are the most common benign tumors of bone and can be classified into isolated and multiple osteochondromas. A great majority of osteochondromas is asymptomatic, painless, slow-growing mass, and incidentally found. However, osteochondromas occurring in adolescence or in adult patients can grow in size and become symptomatic as a result of mechanical irritation of the surrounding soft tissues or peripheral nerves, spinal cord compression, or vascular injury. CASE PRESENTATION: We present a case of a 13-year-old girl with spontaneous hemothorax, the cause of which was identified by limited thoracotomy with the aid of video-assisted thoracic surgery to be bleeding from a diaphragmatic laceration incurred by a costal exostosis on the left sixth rib. Preoperative chest computed tomography (CT) depicted a bony projection arising from the rib and bloody effusion in the intrathoracic cavity, but was unable to discern the bleeding cause from the lung or the diaphragm. This case will highlight our awareness that costal exostosis possibly results in bloody pleural effusion. Meanwhile, English literatures about solitary costal exostosis associated with hemothorax were searched in PubMed and nineteen case reports were obtained. Combined our present case with available literature, a comprehensive understanding of this rare disease entity will further be strengthened. CONCLUSIONS: Injury to the diaphragm is the primary cause of hemothorax caused by costal osteochondroma, including the present case. Thoracic CT scan can help establish a diagnosis of preoperative diagnosis of costal osteochondroma. Surgical intervention should be considered for those patients with symptomatic osteochondroma of the rib. Combined with our case and literature, prophylactic surgical removal of intrathoracic exostosis should be advocated even in asymptomatic patients with the presentation of an inward bony spiculation.

[Hemothorax].

Hemothorax is defined as blood accumulation in the pleural cavity with a hematocrit value of the effusion exceeding 50%. Symptoms and severity vary, ranging from asymptomatic to an imminent state of threatened cardiac arrest. This paper presents the etiology, initial work-up, and treatment of hemothorax, with an emphasis on massive hemothorax requiring an emergent thoracotomy for hemostasis. The etiology of hemothorax can be traumatic, iatrogenic, and non-traumatic/non-iatrogenic. Regardless of the etiology, the initial medical examination should be performed as in the initial trauma examination to evaluate the urgency, the amount of bleeding in the chest cavity, and the coexistence of pneumothorax. If massive hemothorax or tension pneumothorax is present, thoracic tube drainage should be started immediately. Contrast-enhanced computed tomography (CT) should be performed to identify the source of bleeding. Treatment includes fluid and blood transfusions to stabilize the circulation. Anticoagulants and antiplatelet agents should be neutralized, reduced, or withdrawn. Emergent thoracotomy for hemostasis is indicated for massive hemothorax with unstable circulation. Anterior-parasternal thoracotomy performed in the supine position has the advantage of rapid thoracotomy and good visualization. Endovascular therapy is effective when contrast-enhanced CT identifies the source of bleeding.

[Massive Hemorrhage from the Delayed Diaphragmatic Injury due to the Rib Fracture after the Blunt Chest Trauma:Report of a Case].

We report a case of delayed diaphragmatic injury caused by lower rib fractures. A 56-year-old male was referred to our hospital due to the fractures of right lower ribs. Chest X-ray revealed pneumothorax, and the patient was hospitalized for follow-up. On the sixth day after the injury, the patient suddenly complained of chest pain and respiratory distress, and then shock status developed. Chest computed tomography (CT) revealed massive pleural effusion. An emergency operation was performed. The injury of the diaphragm was found. Fracture of the lower rib can cause diaphragmatic injury leading to massive hemorrhage.
