ABSTRACT
INTRODUCTION: Trauma is the leading cause of mortality globally. Penetrating chest trauma is a type of injury that occurs when an object pierces the skin and enters the chest wall. The incidence of penetrating chest trauma is high in the Khyber Pakhtunkhwa Province of Pakistan, with firearm injuries being the most common cause. OBJECTIVE: The objective of this study is to determine the epidemiology and outcome of non-cardiac penetrating chest injuries presented at a tertiary care center in Peshawar. MATERIAL AND METHODS: This retrospective cohort study was conducted from January 2022 to January 2023 at Medical Teaching Institute, Lady Reading Hospital, Peshawar, KPK, Pakistan. Two hundred and three patients who suffered penetrating chest trauma in the Khyber Province of Pakistan between January 2022 and January 2023 were included in this retrospective cohort study. The epidemiology and outcomes were analyzed using IBM SPSS Statistics for Windows, Version 23 (Released 2015; IBM Corp., Armonk, New York, United States). RESULTS: The mean age of the patients was 30.25 ± 16.674 years. Males comprised 183 (90.1%) of the study sample whereas females comprised only one-tenth 20 (9.9%). Gunshot injuries were the predominant mode of penetrating thoracic trauma comprising 128 (63.05%) of all injuries. Injuries inflicted by knife constituted approximately one-fifth of the presentations 44 (21.67%). The remaining injuries labeled 'Others' comprised modes such as road traffic accidents and fall injuries where the predominant mechanism was penetrating injury. The latter comprised 31 (15.27%) of the injuries. CONCLUSION: Penetrating chest trauma is common in the Khyber Pakhtunkhwa Province of Pakistan. Gunshot injury is the most common mode. Males are predominantly affected. Most non-cardiac penetrating chest trauma can be managed conservatively.
ABSTRACT
The landscape of cardiac pacemaker technology has undergone significant evolution over the last two decades, transitioning from simple single-chamber devices to sophisticated multi-chamber rate-responsive systems and cardioverter defibrillators. This progression has introduced a complex array of complications inherent to device implantation and operation, encompassing both mechanical and clinical challenges. These complications notably include lead dislodgment, device migration, venous thrombosis, and hemothorax, which not only affect patient outcomes but also impose substantial economic burdens. This review meticulously analyzes these complications, elucidating their mechanisms, clinical implications, and the economic consequences associated with their management. It also outlines current and emerging strategies aimed at mitigating these complications, emphasizing the need for continual updates in clinical practices and protocols. Through this discourse, the review seeks to equip clinicians with a comprehensive understanding of these complications, thereby enhancing the safety and efficacy of cardiac pacing interventions.
ABSTRACT
Surgical evacuation has long been the standard treatment for hemothorax. However, some patients are not suitable candidates for surgery. Intrapleural fibrinolytic therapy (IPFT) has recently emerged as an effective alternative for managing retained hemothorax. This case report describes two patients with retained hemothorax who were unfit for surgery and were successfully treated with IPFT at our centre. Both patients were deemed unsuitable for surgery due to comorbidities and their overall functional status. They received three cycles of IPFT, each consisting of 2.5 mg of alteplase. This treatment effectively evacuated the retained hemothorax, achieving complete radiological resolution without immediate or delayed complications up to 3 months post-discharge.
ABSTRACT
Sarcomatous serous effusions are uncommon and diagnostically challenging. Dedifferentiated and pleomorphic liposarcomas are rare tumors in pleural effusions revealing highly pleomorphic tumor cells mimicking carcinoma, mesothelioma, melanoma, and other sarcomas. Hematothoracic effusions further complicate the cytologic diagnosis. Correct cytologic recognition is important. We report pleomorphic liposarcoma cytologically detected in effusion fluid in a 56-year-old man who presented with a massive unilateral pleural effusion. ThinPrep showed hemorrhagic effusion fluid characterized by lysed red blood cells, foamy macrophages, and siderophages intermixed with highly pleomorphic predominantly naked mononuclear and giant nuclei. The aggregated siderophages and vacuolated macrophages could be mistaken for tumor cells, whereas the bare nuclei may be missed as nonspecific degenerate changes. Cellblock sections showed highly pleomorphic mononuclear and multinucleated giant tumor cells with diagnostic lipoblasts, intermixed with foamy macrophages and siderophages. Cellblock immunocytochemistry showed staining for vimentin and S-100 protein in the tumor cells. Other lineage-specific immunomarkers were negative. CD68 and calretinin revealed frequent background macrophages and scarce mesothelial cells. The tumor cells were negative for MDM2 and CDK4. The entertained cytopathologic diagnosis was pleomorphic liposarcoma. Core needle biopsy was procured from the mass. The histopathologic features and immunoprofile of the tissue specimen matched the cytopathologic and immunocytochemical findings confirming the cytologic diagnosis of pleomorphic liposarcoma. Pleomorphic liposarcoma is an unexpected cytologically challenging finding in effusions, particularly when compounded by pitfalls introduced by hemosiderotic fluid. Attention to certain cytologic clues mitigate pitfalls. Cellblock is a valuable diagnostic tool when integrated with relevant negative and positive immunocytochemical markers.
ABSTRACT
Bleeding within the pleural space may result in persistent clot formation called retained hemothorax (RH). RH is prone to organization, which compromises effective drainage, leading to lung restriction and dyspnea. Intrapleural fibrinolytic therapy is used to clear the persistent organizing clot in lieu of surgery, but fibrinolysin selection, delivery strategies, and dosing have yet to be identified. We used a recently established rabbit model of RH to test whether intrapleural delivery of single-chain urokinase (scuPA) can most effectively clear RH. scuPA, or single-chain tissue plasminogen activator (sctPA), was delivered via thoracostomy tube on day 7 as either one or two doses 8 h apart. Pleural clot dissolution was assessed using transthoracic ultrasonography, chest computed tomography, two-dimensional and clot displacement measurements, and gross analysis. Two doses of scuPA (1 mg/kg) were more effective than a bolus dose of 2 mg/kg in resolving RH and facilitating drainage of pleural fluids (PF). Red blood cell counts in the PF of scuPA, or sctPA-treated rabbits were comparable, and no gross intrapleural hemorrhage was observed. Both fibrinolysins were equally effective in clearing clots and promoting pleural drainage. Biomarkers of inflammation and organization were likewise comparable in PF from both groups. The findings suggest that single-agent therapy may be effective in clearing RH; however, the clinical advantage of intrapleural scuPA remains to be established by future clinical trials.

Introduction: Traumatic hemothorax is accounted for about 20% of traumatic chest injuries. Although majority can be managed with the timely placement of intercostal tube (ICT) drainage, the remaining pose a challenge owing to high complication rates associated with retained hemothorax. Although various treatment modalities including intrapleural instillation of fibrinolytics, radioimage guided drainage, VATS guided evacuation and thoractomy do exist to address the retained hemothorax, but indications along with timing to employ a specific treatment option is still unclear and ambiguous. Methods: Patient with residual hemothorax (>200 mL) on ultrasonography after 48 h of indwelling ICT was randomized into either early video-assisted thoracic surgery (VATS) or conventional approach cohort. Early VATS cohort was subjected to video-assisted thoracoscopic evacuation of undrained blood along with normal saline irrigation and ICT placement. The conventional cohort underwent intrapleural thrombolytic instillation for 3 consecutive days. The outcome measures were the duration of indwelling ICT, removal rate of tube thoracostomy, length of hospital stay, duration of intensive care unit (ICU) monitoring, need for mechanical ventilation, incidence of pulmonary and pleural complications, and requirement of additional intervention to address undrained hemothorax and mortality rate. Results: The early VATS cohort had shorter length of hospital stay (7.50 ± 0.85 vs. 9.50 ± 3.03, P = 0.060), reduced duration of indwelling ICT (6.70 ± 1.25 vs. 8.30 ± 2.91, P = 0.127) with higher rate of tube thoracostomy removal (70% vs. 30%, P = 0.003) and lesser need of additional interventions (0% vs. 30%, P = 0.105). Thoracotomy (3 patients) and image-guided drainage (4 patients) were additional interventions to address retained hemothorax in the conventional cohort. However, similar length of ventilator assistance (0.7 ± 0.48 vs. 0.60 ± 1.08, P = 0.791) and prolonged ICU monitoring (1.30 ± 1.06 vs. 0.90 ± 1.45, P = 0.490) was observed in early VATS cohort. Both the cohorts had no mortality. Conclusion: VATS-guided early evacuation of traumatic hemothorax is associated with shorter length of hospital stay along with abbreviated indwelling ICT duration, reduced incidence of complications, lesser readmissions, and improved rate of tube thoracostomy removal. However, the duration of ventilator requirement, ICU stay, and mortality remain unchanged.
ABSTRACT
PURPOSE: Post-operative pain after video-assisted thoracoscopic surgery is often treated using thoracic epidural analgesics or thoracic paravertebral analgesics. This article describes a case where a thoracic disc herniation is treated with a thoracoscopic microdiscectomy with post-operative thoracic epidural analgesics. The patient developed a bupivacaine pleural effusion which mimicked a hemothorax on computed tomography (CT). METHODS: The presence of bupivacaine in the pleural effusion was confirmed using a high performance liquid chromatography method. RESULTS: The patient underwent a re-exploration to relieve the pleural effusion. The patient showed a long-term recovery similar to what can be expected from an uncomplicated thoracoscopic microdiscectomy. CONCLUSION: A pleural effusion may occur when thoracic epidural analgesics are used in patents with a corridor between the pleural cavity and epidural space.

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.

The shock index (SI) has been associated with predicting transfusion needs in trauma patients. However, its utility in penetrating thoracic trauma (PTTrauma) for predicting the Critical Administration Threshold (CAT) has not been well-studied. This study aimed to evaluate the prognostic value of SI in predicting CAT in PTTrauma patients and compare its performance with the Assessment of Blood Consumption (ABC) and Revised Assessment of Bleeding and Transfusion (RABT) scores. We conducted a prognostic type 2, single-center retrospective observational cohort study on patients with PTTrauma and an Injury Severity Score (ISS) > 9. The primary exposure was SI at admission, and the primary outcome was CAT. Logistic regression and decision curve analysis were used to assess the predictive performance of SI and the PTTrauma score, a novel model incorporating clinical variables. Of the 620 participants, 53 (8.5%) had more than one CAT. An SI > 0.9 was associated with CAT (adjusted OR 4.89, 95% CI 1.64-14.60). The PTTrauma score outperformed SI, ABC, and RABT scores in predicting CAT (AUC 0.867, 95% CI 0.826-0.908). SI is a valuable predictor of CAT in PTTrauma patients. The novel PTTrauma score demonstrates superior performance compared to existing scores, highlighting the importance of developing targeted predictive models for specific injury patterns. These findings can guide clinical decision-making and resource allocation in the management of PTTrauma.

BACKGROUND: Hemorrhage is the most common major complication after liver biopsy. Hemothorax is one type of bleeding and is very rare and dangerous. Several cases of hemothorax subsequent to liver biopsy have been documented, primarily attributed to injury of the intercostal artery or inferior phrenic artery and a few resulting from lung tissue damage; however, no previous case report of hemothorax caused by injury of musculophrenic artery after liver biopsy has been reported. CASE PRESENTATION: A 45-year-old native Chinese woman diagnosed with primary biliary cirrhosis due to long-term redness in urination and abnormal blood test indicators was admitted to our hospital for an ultrasound-guided liver biopsy to clarify pathological characteristics and disease staging. A total of 2 hours after surgery, the patient complained of discomfort in the right chest and abdomen. Ultrasound revealed an effusion in the right thorax and hemothorax was strongly suspected. The patient was immediately referred to the interventional department for digital subtraction angiography. Super-selective angiography of the right internal thoracic artery was performed which revealed significant contrast medium extravasation from the right musculophrenic artery, the terminal branch of the internal thoracic artery. Embolization was performed successfully. The vital signs of the patient were stabilized after the transarterial embolization and supportive treatment. CONCLUSION: This case draws attention to the musculophrenic artery as a potential source of hemorrhage after percutaneous liver biopsy.

BACKGROUND: Pulmonary arteriovenous malformation (PAVM), also known as pulmonary arteriovenous fistula, is a rare vascular developmental anomaly. Most cases of PAVM are associated with hereditary hemorrhagic telangiectasia (HHT). Hemothorax associated with PAVM is even rarer, and management concerning this complication still challenges. CASE PRESENTATION: A 55-year-old man with sudden onset of dyspnea and chest pain was admitted to our hospital. He had a medical history of epistaxis, intraperitoneal germ cell tumor and PAVM. Chest unenhanced CT revealed the left-sided pleural effusion together with partial passive atelectasis and gradual increase at the interval of six days. Diagnostic thoracocentesis further revealed hemorrhagic effusion. CT angiography (CTA) showed tortuously dilated lumen of the left lower pulmonary artery and PAVM with the formation of aneurysm. Due to his family's refusal of surgery, the patient underwent transcatheter embolization therapy. However, the left pleural effusion did not significantly reduce and there was a slow drop in hemoglobin value even after interventional treatment, indicating the possibility of ongoing active bleeding. Eventually, the patient received lobectomy of the left lower lobe with a satisfactory outcome. CONCLUSIONS: Massive hemothorax resulting from PAVM rupture into the pleural space can lead to fatal outcomes. CTA can accurately diagnose this pathologic condition. Transcatheter embolization is frequently used in the treatment of PAVM, but it may be challenging to achieve the desirable effect in patients with hemothorax. Combined with our case and literature review, direct radical surgery can lead to a successful outcome when PAVM complicated with hemothorax and a large diameter of the draining vein.

Intercostal artery (ICA) injury and bleeding are well-known complications of thoracic procedures and trauma; however, spontaneous ICA bleeding is a rare condition usually associated with specific underlying disorders that typically lead to the weakening of vasculature. Herein, we present a 42-year-old male with a history of Buerger's disease who developed spontaneous bleeding of the second left ICA after undergoing lower limb angioplasty. The bleeding was complicated by a large hemothorax and retropleural hematoma, resulting in hemorrhagic shock that necessitated massive transfusion, embolization, and eventual thoracotomy with evacuation.
ABSTRACT
Introduction: Military working dogs (MWDs) are essential for military operations in a wide range of missions. With this pivotal role, MWDs can become casualties requiring specialized veterinary care that may not always be available far forward on the battlefield. Some injuries such as pneumothorax, hemothorax, or abdominal hemorrhage can be diagnosed using point of care ultrasound (POCUS) such as the Global FAST® exam. This presents a unique opportunity for artificial intelligence (AI) to aid in the interpretation of ultrasound images. In this article, deep learning classification neural networks were developed for POCUS assessment in MWDs. Methods: Images were collected in five MWDs under general anesthesia or deep sedation for all scan points in the Global FAST® exam. For representative injuries, a cadaver model was used from which positive and negative injury images were captured. A total of 327 ultrasound clips were captured and split across scan points for training three different AI network architectures: MobileNetV2, DarkNet-19, and ShrapML. Gradient class activation mapping (GradCAM) overlays were generated for representative images to better explain AI predictions. Results: Performance of AI models reached over 82% accuracy for all scan points. The model with the highest performance was trained with the MobileNetV2 network for the cystocolic scan point achieving 99.8% accuracy. Across all trained networks the diaphragmatic hepatorenal scan point had the best overall performance. However, GradCAM overlays showed that the models with highest accuracy, like MobileNetV2, were not always identifying relevant features. Conversely, the GradCAM heatmaps for ShrapML show general agreement with regions most indicative of fluid accumulation. Discussion: Overall, the AI models developed can automate POCUS predictions in MWDs. Preliminarily, ShrapML had the strongest performance and prediction rate paired with accurately tracking fluid accumulation sites, making it the most suitable option for eventual real-time deployment with ultrasound systems. Further integration of this technology with imaging technologies will expand use of POCUS-based triage of MWDs.
ABSTRACT
OBJECTIVE: The mini-open lateral retropleural (MO-LRP) approach is an effective option for surgically treating thoracic disc herniations, but the approach raises concerns for pneumothorax (PTX). However, chest tube placement causes insertion site tenderness, necessitates consultation services, increases radiation exposure (requires multiple radiographs), delays the progression of care, and increases narcotic requirements. This study examined the incidence of radiographic and clinically significant PTX and hemothorax (HTX) after the MO-LRP approach, without the placement of a prophylactic chest tube, for thoracic disc herniation. METHODS: This study was a single-institution retrospective evaluation of consecutive cases from 2017 to 2022. Electronic medical records were reviewed, including postoperative chest radiographs, radiology and operative reports, and postoperative notes. The presence of PTX or HTX was determined on chest radiographs obtained in all patients immediately after surgery, with interval radiographs if either was present. The size was categorized as large (≥ 3 cm) or small (< 3 cm) based on guidelines of the American College of Chest Physicians. PTX or HTX was considered clinically significant if it required intervention. RESULTS: Thirty patients underwent thoracic discectomy via the MO-LRP approach. All patients were included. Twenty patients were men (67%), and 10 (33%) were women. The patients ranged in age from 25 to 74 years. The most commonly treated level was T11-12 (n = 11, 37%). Intraoperative violation of parietal pleura occurred in 5 patients (17%). No patient had prophylactic chest tube placement. Fifteen patients (50%) had PTX on postoperative chest radiographs; 2 patients had large PTXs, and 13 had small PTXs. Both patients with large PTXs had expansion on repeat radiographs and were treated with chest tube insertion. Of the 13 patients with a small PTX, 1 required 100% oxygen using a nonrebreather mask; the remainder were asymptomatic. One patient, who had no abnormal findings on the immediate postoperative chest radiograph, developed an incidental HTX on postoperative day 6 and was treated with chest tube insertion. Thus, 3 patients (10%) required a chest tube: 2 for expanding PTX and 1 for delayed HTX. CONCLUSIONS: Most patients who undergo thoracic discectomy via the MO-LRP approach do not develop clinically significant PTX or HTX. PTX and HTX in this patient population should be treated with a chest tube only when there are postoperative clinical and radiographic indications.

Traumatic hemothorax is typically easy to diagnose because of the distinct onset of trauma with significant complaints such as severe chest pains. However, in elderly patients, the clinical symptoms are less clear and the frequent use of antithrombotic therapy may prolong the bleeding from a minor fracture. We report a case of traumatic hemothorax from an isolated thoracic vertebral fracture in an elderly patient on anticoagulant and antiplatelet therapy. A 91-year-old male on anticoagulant and antiplatelet therapy was admitted to our hospital with a complaint of persistent hemoptysis after a fall. A computed tomography (CT) demonstrated a worsening right hemothorax and thoracic vertebral fracture without lung or diaphragm injury, rib fracture, or contrast medium extravasation. The patient was taken to the operating room for the exploratory thoracoscopy and evacuation of the hemothorax without a preoperative diagnosis of the bleeding source. The bleeding was from the transverse laceration of the 10th thoracic vertebra exposed to the pleural space. The minor bleeding from the cancellous bone was prolonged, possibly due to the use of anticoagulant and antiplatelet therapy, which was not identified as contrast medium extravasation on chest CT before surgery. In cases of hemothorax with an unclear bleeding source, a vertebral fracture could be considered a source of bleeding even without any signs of bone dislocation or contrast medium extravasation on a CT scan.
ABSTRACT
Background The thoracic ultrasound (TUS) is a monitoring tool that has gained worldwide popularity in various scenarios, offering the opportunity for dynamic, bedside evaluations. Recent studies indicate that the use of TUS enables the diagnosis of pathologies resulting from blunt chest trauma (BCT), yielding favorable outcomes. This study aimed to compare the utility of TUS versus chest radiography (CXR) in diagnosing pulmonary pathologies resulting from closed-chest traumas. Methodology A prospective cross-sectional study was conducted with a sample of 58 patients diagnosed with BCT who sought emergency care at the "Dr. Luis Razetti" University Hospital in Barcelona, Venezuela, from November 2023 to January 2024. Results Of the patients, 75.9% (n = 44) were male, with an average age of 37.8 years (standard deviation = 18.4 years). Injuries were reported in 8.6% (n = 5) of the patients, including 60% (n = 3) pneumothorax and 40% (n = 2) hemothorax. Ultrasound results coincided with CXR in 94.8% (n = 55) of the cases, with a Cohen's kappa coefficient of 0.9 (95% confidence interval (CI) = 0.642-1.0). TUS demonstrated higher sensitivity than CXR (100% vs. 60%) for detecting hemothorax and pneumothorax in patients with BCT, with an area under the receiver operating characteristic curve of 0.991 (95% CI = 0.968-1.013). Conclusions BCT predominantly occurred in young males, resulting primarily in pneumothorax and hemothorax lesions, detectable with higher sensitivity through TUS compared to CXR. The use of TUS should be considered an essential component of the initial assessment for individuals with BCT.
ABSTRACT
Introduction: Pseudoaneurysm, or false aneurysm, is a clinical entity caused by rupture of the arterial wall, leading to blood leakage that is confined by sorroundig tissue. Massive hemothorax constitutes a life-threatening condition demanding timely and accurate medical response. Case report: A puerperal presented with a massive hemothorax precipitated by a traumatic cesarean section due to hemorrhage from a pseudoaneurysm of the left internal thoracic artery. Initial treatment involved a sternotomy, followed by a conclusive therapy via angioembolization. Conclusion: Precise assessment, including the measurement and localization of the ITA pseudoaneurysm is crucial to formulate an appropriate therapeutic strategy. Current medial practice favors endovascular embolization as a reliable and minimally invasive alternative to open surgery, establishing ir as the treatment of choice.
ABSTRACT
Introduction and importance: COVID-19 has been widely spread in the last 2 years. Hemothorax is considered one of the rarest complications of COVID-19. Case presentation: The authors herein report a case of a 52-year-old patient of COVID-19 that was complicated with abrupt massive hemothorax with hemodynamic instability. Emergent thoracostomy drained almost 4500 ml of blood within 48 h. Thoracoscopy was also performed draining an additional 2000 ml of blood and clots. No further bleeding occurred. Unfortunately, the patient died of septic shock and multiorgan dysfunction. Clinical discussion: Hemothorax has been reported in seven patients with COVID-19 in the medical literature. Six patients had severe infection with veno-venous extra-corporeal membranous oxygenation (VV-ECMO), and the seventh patient had necrotizing pneumonia. To our knowledge, this represents the first patient of an abrupt massive hemothorax in a COVID-19 patient just before recovery. Conclusion: Post-COVID-19 hemothorax should be suspected in severe cases with sudden clinical deterioration and evidence of pleural effusion.
ABSTRACT
PURPOSE: The aim of this case report is to report that delayed hemothorax is possible after anterior vertebral body tethering (aVBT) and to illustrate the course of treatment. METHODS: We present a 15-year-old boy with adolescent idiopathic scoliosis who underwent an anterior thoracoscopic assisted vertebral body tethering who developed a massive right-sided hemothorax 12 days post-operatively. A chest tube was placed to drain the hemothorax and later required embolectomy with tissue plasminogen activator (TPA) to drain the retained hemothorax. RESULTS: At 1 month follow up post discharge the patient was asymptomatic, and radiograph did not demonstrate evidence of residual hemothorax and scoliosis. We have followed this patient for 5 years postoperative and he continues to do well clinically and radiographically. CONCLUSIONS: Pulmonary complications are a known drawback of anterior thoracoscopic spinal instrumentation. Delayed hemothorax is possible after aVBT. In the case of a retained hemothorax, chest tube treatment with TPA is a safe and effective method of embolectomy.
