Chest Tube Size Selection: Evaluating Provider Practices, Treatment Efficacy, and Complications in Management of Thoracic Trauma.

BACKGROUND: The standard for managing traumatic pneumothorax (PTX), hemothorax (HTX), and hemopneumothorax (HPTX) has historically been large-bore (LB) chest tubes (>20-Fr). Previous studies have shown equal efficacy of small-bore (SB) chest tubes (≤19-Fr) in draining PTX and HTX/HPTX. This study aimed to evaluate provider practice patterns, treatment efficacy, and complications related to the selection of chest tube sizes for patients with thoracic trauma. METHODS: A retrospective chart review was performed on adult patients who underwent tube thoracostomy for traumatic PTX, HTX, or HPTX at a Level 1 Trauma Center from January 2016 to December 2021. Comparison was made between SB and LB thoracostomy tubes. The primary outcome was indication for chest tube placement based on injury pattern. Secondary outcomes included retained hemothorax, insertion-related complications, and duration of chest tube placement. Univariate and multivariate analyses were performed. RESULTS: Three hundred and forty-one patients were included and 297 (87.1%) received LB tubes. No significant differences were found between the groups concerning tube failure and insertion-related complications. LB tubes were more frequently placed in patients with penetrating MOI, higher average ISS, and higher average thoracic AIS. Patients who received LB chest tubes experienced a higher incidence of retained HTX. DISCUSSION: In patients with thoracic trauma, both SB and LB chest tubes may be used for treatment. SB tubes are typically placed in nonemergent situations, and there is apparent provider bias for LB tubes. A future randomized clinical trial is needed to provide additional data on the usage of SB tubes in emergent situations.

Acupuncture-Induced Hemothorax with Hypovolemic Shock: A Case Report.

This report describes a very rare but life-threatening complication that occurred in a 43-year-old woman after an acupuncture (AC) for lumbago. The patient presented to the emergency department displaying symptoms indicative of shock. Physical examination revealed the absence of breath sounds on the right thoracic side, further investigations indicated the presence of a hemothorax. Emergency surgery was performed to evacuate the hemothorax and control bleeding from two intercostal veins. Although AC is often considered a gentle form of medicine, it is important to recognize that it can occasionally result in severe complications, especially when acupoints are used on the thorax.

Massive haemothorax and haemorrhagic shock due to cervical vascular injury caused by a seat belt.

A woman in her 50s was transported to our hospital after experiencing a road traffic crash that led to a massive haemothorax and haemorrhagic shock due to a cervical vascular injury caused by the seat belt. Contrast-enhanced CT of the chest showed extravascular leakage of the contrast medium from the vicinity of the right subclavicular area and fluid accumulation in the thoracic cavity. The patient was intubated, and a thoracic drainage catheter was placed. She underwent angiography and embolisation of the right costocervical trunk, right thyrocervical trunk and right suprascapular artery using a gelatine sponge and 25% N-butylcyanoacrylate-Lipiodol. She was extubated on the second day after stabilisation of the respiratory and circulatory status. In cases where the bleeding vessel is known and an emergency thoracotomy can serve as a backup, embolisation by interventional radiology should be considered the initial treatment approach.

Efficacy and safety of transcatheter arterial embolization for hemodynamically unstable bleeding after percutaneous transthoracic needle biopsy.

PURPOSE: To evaluate the safety and efficacy of transcatheter arterial embolization (TAE) in controlling hemodynamically unstable bleeding following a percutaneous transthoracic needle biopsy (PTNB). METHODS: A total of seven patients (four men and three women; mean age, 62 ± 12 years) who received TAE for post-PTNB bleeding between May 2007 and March 2022 were included. The observed types of bleeding were hemothorax (n = 3), hemoptysis (n = 2), and a combination of both (n = 2). In patients with active bleeding, the technical success of TAE was defined as superselective embolization of the target artery with no active bleeding visible on post-TAE angiography. Clinical success was defined as sustained cessation of bleeding without hemodynamic instability, requirement of repeat TAE, or the need for post-TAE hemostatic surgery during the initial admission. The metrics analyzed included technical and clinical success rates, complications, and 30-day mortality. RESULTS: All seven patients achieved technical success, with a clinical success rate of 86% (6/7). Six patients were discharged alive, while one patient died of respiratory failure accompanied by hemothorax 19 days post-biopsy. The angiographic findings associated with bleeding were contrast media extravasation or pseudoaneurysm (n = 3) and vascular hypertrophy with tortuosity (n = 2). The implicated bleeding arteries included the intercostal artery (n = 2), bronchial artery (n = 2), and internal thoracic artery (n = 1). In two cases, no clear bleeding foci were identified; nonetheless, prophylactic embolization was performed on the right intercostal artery (n = 1) and right intercostobronchial trunk (n = 1). The embolic agents utilized included microcoils (n = 1), gelatin sponge particles (n = 2), polyvinyl alcohol (PVA) with gelatin sponge particles (n = 1), PVA with microcoils (n = 1), microcoils with gelatin sponge particles (n = 1), and microcoils with n-butyl-2-cyanoacrylate and gelatin sponge particles (n = 1). The 30-day mortality rate was 14% (1/7). No ischemic complications related to TAE were observed. CONCLUSION: The study suggests that TAE is safe and effective for controlling hemodynamically unstable bleeding following a PTNB.

Spontaneous large volume hemothorax managed with a small-bore chest tube.

A 67-year-old male with metastatic lung cancer presented with acute shortness of breath and increasing oxygen requirements. He had a decreasing hemoglobin for which he required red blood cell transfusions. His chest X-ray showed near complete white-out of the left lung. Bedside ultrasound (Handheld Sonostar C4PL) showed a large pleural effusion with swirling echogenic material suggestive of plankton sign. The pleural effusion was aspirated and showed frank blood, after which a small-bore chest tube (SBCT) was inserted. A total of 3200 mL of blood was drained with the SBCT. There was complete clearance of the pleural space, and no further blood product transfusions were needed. This case highlights that conservative management can be considered in patients with spontaneous hemothorax due to metastatic disease.

Outcomes of Pigtail Catheter Placement versus Chest Tube Placement in Adult Thoracic Trauma Patients: A Systematic Review and Meta-Analysis.

INTRODUCTION: A debate currently exists regarding the efficacy of pigtail catheters vs chest tubes in the management of thoracic trauma. This meta-analysis aims to compare the outcomes of pigtail catheters vs chest tubes in adult trauma patients with thoracic injuries. METHODS: This systematic review and meta-analysis were conducted using PRISMA guidelines and registered with PROSPERO. PubMed, Google Scholar, Embase, Ebsco, and ProQuest electronic databases were queried for studies comparing the use of pigtail catheters vs chest tubes in adult trauma patients from database inception to August 15th, 2022. The primary outcome was the failure rate of drainage tubes, defined as requiring a second tube placement or VATS, unresolved pneumothorax, hemothorax, or hemopneumothorax requiring additional intervention. Secondary outcomes were initial drainage output, ICU-LOS, and ventilator days. RESULTS: A total of 7 studies satisfied eligibility criteria and were assessed in the meta-analysis. The pigtail group had higher initial output volumes vs the chest tube group, with a mean difference of 114.7 mL [95% CI (70.6 mL, 158.8 mL)]. Patients in the chest tube group also had a higher risk of requiring VATS vs the pigtail group, with a relative risk of 2.77 [95% CI (1.50, 5.11)]. CONCLUSIONS: In trauma patients, pigtail catheters rather than chest tubes are associated with higher initial output volume, reduced risk of VATS, and shorter tube duration. Considering the similar rates of failure, ventilator days, and ICU length-of-stay, pigtail catheters should be considered in the management of traumatic thoracic injuries. STUDY TYPE: Systematic Review and meta-analysis.

Primary Pulmonary Synovial Sarcoma with Hemothorax: a Case Report.

Background: Synovial sarcoma is a rare and aggressive soft tissue malignancy most commonly arises from periarticular tissue of the extremities. Although several cases in the literature have reported different origins, primary pulmonary synovial sarcoma (PPSS) is an exceedingly rare and underrecognized entity, accounting for 0.5% of all lung malignancies. Clinical presentation includes chest pain, dyspnea, cough, and hemoptysis. The finding of hemothorax is a rare presentation and was barely reported in the literature. Due to its rarity and aggressive nature, the optimal treatment is unclear, while the mainstay remains surgical resection with chemo- and/or radiation therapy. Objective: To report a case of hemorrhagic effusion subsequently diagnosed with primary pulmonary synovial sarcoma with the main objective of enriching the literature regarding this rare malignancy. Case report: A 52-year-old male smoker with a background of coronary artery disease, hypertension, and diabetes mellitus was referred to our hospital. The patient presented with a history of chest pain, dyspnea, and massive right-sided pleural effusion. Laboratory investigations were unremarkable except for anemia. Chest x-ray showed a complete opacity on the right lower zone with right-sided pleural effusion. Thoracentesis was done and revealed hemorrhagic exudative effusion. Computed tomography (CT) scan showed a right heterogeneous lung mass compressing the medial segment of the middle lobe. Subsequently, the patient underwent bronchoscopy, which showed compression and edema on the right middle lobe bronchus with traces of blood coming from the right lower lobe. The patient underwent a right posterolateral thoracotomy, a fungating mass eroding the medial segment of the middle lobe was resected that was diagnosed as high-grade primary pulmonary synovial sarcoma. Radiotherapy was instituted. The patient died after two years due to recurrence. Conclusion: PPSS is an aggressive disease with poor prognostic outcomes, and Its presentation is almost similar to other lung malignancies. Meanwhile, there is no definitive management guideline, and most management depends on surgical resection if feasible with adjuvant chemo-radiation therapy.

Transcatheter arterial embolization for hemothorax caused by spinal fracture without arterial injury: a case report and review of the literature.

BACKGROUND: Spinal fractures rarely cause hemothorax, and no treatment consensus has been reached. Conservative treatment is generally selected in cases without arterial injury, but there have been some reports of uncontrolled bleeding. Here we report a case of hemothorax caused by spinal fracture without arterial injury treated with transcatheter arterial embolization. CASE PRESENTATION: An 88-year-old Japanese woman with back pain was diagnosed with hemothorax due to bleeding from an unstable fracture of the tenth thoracic vertebra. Contrast-enhanced computed tomography revealed no obvious arterial injury. We performed transcatheter arterial embolization of the bilateral tenth intercostal arteries to prevent rebleeding. The hemothorax did not worsen until surgical spinal fixation 9 days post-transcatheter arterial embolization, and she was discharged 30 days after admission. CONCLUSION: Transcatheter arterial embolization for hemothorax caused by spinal fractures without obvious arterial injury may be a useful bridge to spinal fixation.

The Volume of Thoracic Irrigation Is Associated With Length of Stay in Patients With Traumatic Hemothorax.

INTRODUCTION: Irrigation of the thoracic cavity at tube thoracostomy (TT) placement may decrease the rate of a retained hemothorax (RHTX); however, other resource utilization outcomes have not yet been quantified. This study evaluated the association of thoracic irrigation during TT with the length of stay and outcomes in patients with traumatic hemothorax (HTX). METHODS: A retrospective chart review was performed of adult patients receiving a TT for HTX at a single, urban Level 1 Trauma Center from January 2019 to December 2020. Those who underwent irrigation during TT at the discretion of the trauma surgeon were compared to a control of standard TT without irrigation. Death within 30 d, as well as TTs, placed at outside hospitals, during traumatic arrest or thoracic procedures, and for isolated pneumothoraces were excluded. The primary outcome was the length of stay as hospital-free, ICU-free, and ventilator-free days (30-day benchmark). Subgroup analysis by irrigation volume was conducted using one-way ANOVA testing with P < 0.05 considered statistically significant. RESULTS: Eighty-two (41.4%) of 198 patients underwent irrigation during TT placement. Secondary interventions, thoracic infections, and TT duration were not statistically different in the irrigated cohort. Hospital-free and ICU-free days were higher in the irrigated patients than in the controls. Groups irrigated with ≥1000 mL had significant more hospital-free days (P = 0.007) than those receiving less than 1000 mL. CONCLUSIONS: Patients with traumatic HTX who underwent thoracic irrigation at the time of TT placement had decreased hospital and ICU days compared to standard TT placement alone. Specifically, our study demonstrated that patients irrigated with a volume of at least 1000 mL had greater hospital-free days compared to those irrigated with less than 1000 mL.

Predictors of Readmission Following Treatment for Traumatic Hemothorax.

INTRODUCTION: Retained-hemothorax after trauma can be associated with prolonged hospitalization, empyema, pneumonia, readmission, and the need for additional intervention. The purpose of this study is to reduce patient morbidity associated with retained-hemothorax by defining readmission rates and identifying predictors of readmission after traumatic hemothorax. METHODS: The Nationwide Readmission Database for 2017 was queried for patients with an index admission for traumatic hemothorax during the first 9 mo of the year. Deaths during the index admission were excluded. Data collected includes demographics, injury mechanism, outcomes and interventions including chest tube, video-assisted thoracoscopic surgery, and thoracotomy. Chest-related readmissions (CRR) were defined as hemothorax, pleural effusion, pyothorax, and lung abscess. Univariate and multivariate analysis were used to identify predictors of readmission. RESULTS: There were 13,903 patients admitted during the study period with a mean age of 53 ± 21, 75.2% were admitted after blunt versus 18.3% penetrating injury. The overall 90-day readmission rate was 20.8% (n = 2896). The 90-day CRR rate was 5.7% (n = 794), with 80.5% of these occurring within 30 d. Of all CRR, 62.3% (n = 495) required an intervention (chest tube 72.7%, Thoracotomy 26.9%, video-assisted thoracoscopic surgery 0.4%). Mortality for CRR was 6.2%. Predictors for CRR were age >50, pyothorax or pleural effusion during the index admission and discharge to another healthcare facility or skilled nursing facility. CONCLUSIONS: Majority of CRR after traumatic hemothorax occur within 30 d of discharge and frequently require invasive intervention. These findings can be used to improve post discharge follow-up and monitoring.

Acute Presentation of a High-Grade Myxofibrosarcoma Originating in the Thoracic Wall: A Case Report.

We report the first case of a patient with myxofibrosarcoma (MFS) who presented acutely with a rib fracture and developed a rapidly expanding loculated hemothorax after chest trauma. The patient was taken to the operating room for evacuation of hemothorax, and samples and biopsy specimens were taken for cytologic and pathologic examination. Final report with immunohistochemical staining showed a high-grade MFS. After the procedure, there was clinical and radiological improvement, and the patient was followed up as an outpatient. Myxofibrosarcoma is a very rare and aggressive connective tissue neoplasm with variable presentations. Surgical resection is the preferred treatment. Prompt diagnosis and adequate management of these tumors are important to reduce their high local recurrence and distant metastasis rates. Therefore, it is important to be aware of its common and uncommon presentations.

Time to diagnosis of acute complications after cardiovascular implantable electronic device insertion and optimal timing of discharge within the first 24 hours.

BACKGROUND: More than 3 million cardiovascular implantable electronic devices (CIEDs) are implanted annually. There are minimal data regarding the timing of diagnosis of acute complications after implantation. It remains unclear whether patients can be safely discharged less than 24 hours postimplantation. OBJECTIVE: The purpose of this study was to determine the precise timing of acute complication diagnosis after CIED implantation and optimal timing for same-day discharge. METHODS: A retrospective cohort analysis of adults 18 years or older who underwent CIED implantation at a large urban quaternary care medical center between June 1, 2015, and March 30, 2020, was performed. Standard of care included overnight observation and chest radiography 6 and 24 hours postprocedure. Medical records were reviewed for the timing of diagnosis of acute complications. Acute complications included pneumothorax, hemothorax, pericardial effusion, lead dislodgment, and implant site hematoma requiring surgical intervention. RESULTS: A total of 2421 patients underwent implantation. Pericardial effusion or cardiac tamponade was diagnosed in 13 patients (0.53%), pneumothorax or hemothorax in 19 patients (0.78%), lead dislodgment in 11 patients (0.45%), and hematomas requiring surgical intervention in 5 patients (0.2%). Of the 48 acute complications, 43 (90%) occurred either within 6 hours or more than 24 hours after the procedure. Only 3 acute complications identified between 6 and 24 hours required intervention during the index hospitalization (0.12% of all cases). CONCLUSION: Most acute complications are diagnosed either within the first 6 hours or more than 24 hours after implantation. With rare exception, patients can be considered for discharge after 6 hours of appropriate monitoring.

Massive hemothorax in a pregnant patient with neurofibromatosis type 1.

BACKGROUND: Reports of spontaneous hemothorax in patients with neurofibromatosis type 1 are scarce despite the severe complication. We herein present the first case of hemothorax in a neurofibromatosis type 1 patient during pregnancy and discuss the difficulty associated with its diagnosis and treatment. CASE PRESENTATION: A 39-year-old female at 34 weeks gestation presented with sudden left back pain and dyspnea. Chest radiography revealed massive left pleural effusion. Computed tomography showed bleeding from the intercostal artery. Although the patient appeared hemodynamically stable, the fetus was in a critical condition. Emergency caesarean section was performed within 1 hour. Subsequently, we performed endovascular coil embolization of the intercostal artery. While this intensive treatment saved the patient, her fetus could not be rescued. CONCLUSIONS: Patients with neurofibromatosis type 1 may develop massive hemothorax without gross lesions. In late pregnancy, sufficient infusion and quick hemostasis are essential and can be lifesaving.

Successful Transcatheter Arterial Embolization for Hemothorax from a Spontaneous Rupture of Hepatocellular Carcinoma Metastasis to the Chest Wall in an Elderly Patient.

An 87-year-old man with hepatocellular carcinoma (HCC) presented with right-sided chest pain. Computed tomography revealed right bloody pleural effusion and an extravasation from an arterially enhanced mass in the right seventh posterior intercostal space. These findings indicated hemothorax from a rupture of HCC metastasis to the chest wall. Angiography of the intercostal arteries confirmed a hypervascular tumor, and transcatheter arterial embolization resulted in hemostasis. He was discharged with palliative care and remains alive after 9 months. Although hemothorax represents an unusual, life-threatening complication of HCC, our case suggests that transcatheter treatment can achieve hemostasis and a favorable survival even in elderly patients.

Management of simple and retained hemothorax: A practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: Traumatic hemothorax poses diagnostic and therapeutic challenges both acutely and chronically. A working group of the Eastern Association for the Surgery of Trauma convened to formulate a practice management guideline for traumatic hemothorax. METHODS: We formulated four questions: whether tube thoracostomy vs observation be performed, should pigtail catheter versus thoracostomy tube be placed to drain hemothorax, should thrombolytic therapy be attempted versus immediate thoracoscopic assisted drainage (VATS) in retained hemothorax (rHTX), and should early VATS (≤4 days) versus late VATS (>4 days) be performed? A systematic review was undertaken from articles identified in multiple databases. RESULTS: A total of 6391 articles were identified, 14 were selected for guideline construction. Most articles were retrospective with very low-quality evidence. We performed meta-analysis for some of the outcomes for three of the questions. CONCLUSIONS: For traumatic hemothorax we conditionally recommend pigtail catheters, in hemodynamically stable patients. In patients with rHTX, we conditionally recommend VATS rather than attempting thrombolytic therapy and recommend that it should be performed early (≤4 days).

Randomized Clinical Trial of 14-French (14F) Pigtail Catheters versus 28-32F Chest Tubes in the Management of Patients with Traumatic Hemothorax and Hemopneumothorax.

INTRODUCTION: Traditional management of traumatic hemothorax/hemopneumothorax (HTX/HPTX) has been insertion of large-bore 32-40 French (Fr) chest tubes (CTs). Retrospective studies have shown 14Fr percutaneous pigtail catheters (PCs) are equally effective as CTs. Our aim was to compare effectiveness between PCs and CTs by performing the first randomized controlled trial (RCT). We hypothesize PCs work equally as well as CTs in management of traumatic HTX/HPTX. METHODS: Prospective RCT comparing 14Fr PCs to 28-32Fr CTs for management of traumatic HTX/HPTX from 07/2015 to 01/2018. We excluded patients requiring emergency tube placement or who refused. Primary outcome was failure rate defined as retained HTX or recurrent PTX requiring additional intervention. Secondary outcomes included initial output (IO), tube days and insertion perception experience (IPE) score on a scale of 1-5 (1 = tolerable experience, 5 = worst experience). Unpaired Student's t-test, chi-square and Wilcoxon rank-sum test were utilized with significance set at P < 0.05. RESULTS: Forty-three patients were enrolled. Baseline characteristics between PC patients (N = 20) and CT patients (N = 23) were similar. Failure rates (10% PCs vs. 17% CTs, P = 0.49) between cohorts were similar. IO (median, 650 milliliters[ml]; interquartile range[IR], 375-1087; for PCs vs. 400 ml; IR, 240-700; for CTs, P = 0.06), and tube duration was similar, but PC patients reported lower IPE scores (median, 1, "I can tolerate it"; IR, 1-2) than CT patients (median, 3, "It was a bad experience"; IR, 3-4, P = 0.001). CONCLUSION: In patients with traumatic HTX/HPTX, 14Fr PCs were equally as effective as 28-32Fr CTs with no significant difference in failure rates. PC patients, however, reported a better insertion experience. www.ClinicalTrials.gov Registration ID: NCT02553434.
