Case report: Spontaneous hemothorax following anticoagulation for microthrombi in severe COVID pneumonia.

Background: Anticoagulant therapy has become a hallmark of treatment for critically ill COVID patients. Gastrointestinal and intracranial hemorrhage are known major complications of anticoagulation, but spontaneous hemothorax is a rare event, particularly in the absence of pre-existing structural lung disease, vascular malformations, or genetic bleeding diatheses. Herein is a case of spontaneous hemothorax following anticoagulation for microthrombi in a patient with acute hypoxic respiratory failure due to Covid pneumonia. Case presentation: A 49 year old male with hypertension, asthma, and obesity was admitted for acute hypoxic respiratory failure due to Covid pneumonia. He was treated with dexamethasone, baricitinib, and therapeutic enoxaparin as empiric therapy for severe COVID disease. He subsequently developed a massive right hemothorax with associated hemorrhagic shock, which required initiation of massive transfusion protocol, vasopressor support and mechanical ventilation. No clear etiology for the hemothorax was determined upon investigations. The patient eventually improved and was discharged to a skilled nursing facility on chronic oxygen therapy. Conclusions: Various mechanisms have been proposed for the development of non-traumatic hemothoraces, including tearing of adhesions and rupture of vascularized bullae. Such explanations find support in radiologic and pathologic studies of pleural changes in Covid pneumonia, and likely played a role in the hemorrhage experienced by our patient.

MULTIPLE RIB FRACTURES, PLEURAL EFFUSION AND RIGHT-SIDED DIAPHRAGMATIC HERNIATION OF THE COLON INTO THE CHEST ASSOCIATED WITH CHRONIC COUGH AFTER COVID-19.

Rib fractures are an infrequent consequence of severe cough. In some patients, undetected rib fractures can lead to life-threatening outcomes. The case of a 73-year-old man who presented with shortness of breath and a worsening dry cough from a SARS-CoV-2 infection for 4 weeks is described. In the emergency department, he was found to be hypoxic and hypotensive. Imaging studies revealed a large right pleural effusion, multiple rib fractures, and right-sided herniation of the colon into the chest. He was admitted to the cardiothoracic intensive care unit where he underwent a flexible bronchoscopy, right video-assisted thoracoscopic surgery, evacuation of a haemothorax, complete decortication, and repair of a diaphragmatic hernia. This case is an unusual presentation of an amalgamation of rare complications resulting from an unrelenting, poorly controlled SARS-CoV-2 infection cough that prompted rapid recognition and swift action. LEARNING POINTS: Physical examination and plain radiography frequently miss costal arch fractures if no bone pathology or history of trauma is present.Controlling cough is important, and decreases the chances of complications and rupture of organs.New-onset chest pain with a background of chronic cough makes cough-induced rib fracture a probable differential diagnosis. Pleural effusion in a patient presenting with cough and a rib fracture should make clinicians suspect haemothorax.

Spontaneous hemothorax in a 48-year-old man with COVID-19 acute respiratory distress syndrome.

A 48-year-old man presented with gradually worsening dyspnea three days after testing positive for COVID-19. He was admitted to the intensive care unit on maximum high flow nasal cannula settings and subsequently intubated for hypoxic respiratory failure due to COVID-19 pneumonia. Two weeks into the patient's hospital course, he unexpectedly developed worsening hypotension with multiple vasopressor requirements. Labs revealed an unexpected hemoglobin drop from 12.5 to 7.9 g/dL. Chest radiograph showed near complete opacification of the right hemithorax concerning for hemothorax. This case presentation describes a rare phenomenon of spontaneous hemothorax in a patient with COVID-19.

Spontaneous hemothorax in a 10-year-old boy with COVID-19.

Spontaneous hemothorax occurs in the absence of trauma or iatrogenic causes. Etiologies of spontaneous hemothorax in children include connective tissue disease, neoplasia and coagulopathy, which is associated with thromboembolic events. We present the case of a 10-year-old chronic hemodialysis patient with spontaneous hemothorax with a concurrent COVID-19 infection.

Pulmonary arteriovenous malformation and inherent complications with solitary lung nodule biopsy-literature overview and case report.

Pulmonary arteriovenous malformation, also known as an arteriovenous fistula, is typically a congenital disease caused by structural deficiencies, particularly the lack of capillary wall development, leading to the abnormal dilation of the pulmonary capillaries. The majority of pulmonary arteriovenous malformation cases are associated with Rendu-Osler-Weber syndrome, also known as hereditary hemorrhagic telangiectasia. Pulmonary arteriovenous malformation rarely occurs due to chest trauma. Pulmonary arteriovenous malformations are long-lasting and often first diagnosed in adults. More than two-thirds of pulmonary arteriovenous malformation lesions are found in the lower lung lobe and the subpleural area, and the vast majority of cases present with the monofocal form. The initial diagnosis is often based on the identification of a solitary pulmonary nodule. However, a solitary nodule detected on chest computed tomography that is not correctly diagnosed as pulmonary arteriovenous malformation, even after intravenous contrast injection, can lead to the performance of a transthoracic biopsy. Biopsy of pulmonary arteriovenous malformations can lead to stroke occurrence, during which the patient often presents with severe pleural bleeding, which can have lifelong consequences if not immediately treated. We report a case of pulmonary arteriovenous malformation that was discovered incidentally in an adult patient who underwent non-contrast computed tomography. Misdiagnosis occurred, and transthoracic lung biopsy was performed. Complications were discovered late, and the patient underwent surgical pulmonary arteriovenous malformation removal and was treated for hemothorax.

Spontaneous tension hemothorax in a severe COVID-19 patient receiving ECMO therapy: The other side of COVID-19-associated coagulopathy.

As opposed to widely recognized Coronavirus Disease 2019 (COVID-19)-associated thrombotic events, the unusual but serious bleeding complications in COVID-19 patients are worth-mentioned. Here, we describe a 44-year-old man afflicted by COVID-19 pneumonia with acute respiratory distress syndrome (ARDS) and submassive pulmonary embolism. The patient's condition initially improved with the prescription of ECMO, tocilizumab, and hemoadsorption, however, he later developed spontaneous tension hemothorax, which is considered rare but devastating in the setting of COVID-19. While the exact pathogenesis of COVID-19-associated bleeding events remains poorly understood, we aim to highlight the other aspect of coagulation dysfunction potentially caused by COVID-19.

Hemopneumothorax as an Unusual and Delayed Complication of Coronavirus Disease 2019 Pneumonia: A Case Report.

The increasing number of studies published on coronavirus disease 2019 (COVID-19) pneumonia has improved our knowledge of the disease itself and its complications. Despite a considerable number of publications on COVID-19 pneumonia-associated pneumothorax, no article on spontaneous hemopneumothorax has been found in the English-language literature. According to published case reports, pneumothorax generally occurs in hospitalized patients during treatment, whereas cases that arise in the late period after discharge are exceptional. Herein, we present a case of spontaneous hemopneumothorax occurring as a late complication of COVID-19 pneumonia on day 17 after discharge.

Spontaneous massive hemothorax as a complication of necrotizing pneumonia in a patient with severe acute respiratory syndrome coronavirus 2 induced acute respiratory distress syndrome: a case report.

BACKGROUND: We present an unusual bleeding complication in a patient with severe acute respiratory distress syndrome in coronavirus disease 2019. CASE PRESENTATION: The patient, a 63-year-old Caucasian man, received venovenous extracorporeal membrane oxygenation support after rapid deterioration of lung function on day 6 after admission to hospital. After initial stabilization on lung protective ventilation and prone positioning, he started to develop mild bleeding complications until he went into occult profound hemorrhagic shock. Causative was a massive hemothorax of the right hemithorax with mediastinal shifting due to spontaneous bleeding from a pulmonal artery in a heavily remodeled right inferior lobe. Histopathological examination of the resected tissue showed signs of an organizing fibrinous pneumonia with focal parenchyma necrosis. After surviving a massive bleeding event caused by necrotizing pneumonia, the patient made a swift recovery and was discharged to rehabilitation 31 days after initial hospital admission. CONCLUSIONS: The combination of severely elevated inflammatory markers and pulmonary hemorrhage should arouse suspicion of necrotizing pneumonia. In necrotizing pneumonia, the possibility of severe intrathoracic bleeding complications should be kept in mind if it comes to sudden deterioration of the patient.

Hemothorax after oocyte retrieval in a patient with a history of COVID-19: a case report.

Spontaneous hemothorax is a rare disorder characterized by pleural fluid hematocrit greater than 50% of the peripheral blood hematocrit without natural or iatrogenic trauma to the lungs or pleural space. Since the first case of COVID-19, more than 85 million cases have been confirmed and most patients have sustained symptoms after more than six months of acute infection. This paper reports the case of a 38-year-old woman without signs of endometriosis and a history of COVID-19 infection who developed spontaneous hemothorax after oocyte retrieval. Three months before undergoing assisted reproductive technology (ART) treatment, the patient had a symptomatic COVID-19 infection with a negative PCR test and a positive IgG test four weeks after the onset of symptoms. Controlled ovarian stimulation and oocyte retrieval were conducted uneventfully. Two hours after oocyte retrieval, the patient developed nausea and mild hypogastric pain. Ten hours after the procedure, the patient went to the emergency department with abdominal pain. Chest computed tomography scans revealed moderate right pleural effusion and laminar left pleural effusion. Since the patient had respiratory symptoms, the choice was made to drain the pleural fluid. Fluid analysis confirmed the patient had right hemothorax (400 mL). After drainage, the patient's clinical and imaging signs improved gradually without complications. The patient was asymptomatic one week after the procedure.

Rare findings of spontaneous hemothorax and small subpleural lung hematoma in a COVID-19 patient: A case report.

Hemothorax (HT) and pulmonary hematoma represent rare complications of anticoagulant therapy. We present a rare case of a 53-year-old man with COVID-19 pneumonia who showed, in a follow-up computed tomography (CT) scan 13 days after hospitalization, a left HT and a small hyperdense area in a subpleural location and compatible with a small subpleural hematoma. This patient was being treated with a subcutaneous administration of low-molecular-weight heparin (100UI/kg/BID). No vascular malformations were visualized on the CT pulmonary angiography. Herein, we report the first case of both a spontaneous HT and a lung subpleural hematoma in a COVID-19 patient, probably caused by anticoagulant therapy.

[Successful treatment of a geriatric COVID-19 patient with severe chest trauma : An interdisciplinary case report]. / Erfolgreiche Behandlung des schweren Thoraxtraumas einer geriatrischen COVID-19-Patientin : Ein Fallbericht von interdisziplinärer Bedeutung.

The coronavirus disease 2019 (COVID-19) has spread rapidly worldwide and leads to high morbidity and mortality. Clinical experience regarding the surgical management in COVID-19 patients is limited. We report the interdisciplinary approach in a COVID-19 patient with severe thoracic trauma and pulmonary symptoms, who was admitted to the emergency unit after blunt chest trauma with dislocated serial rib fractures and concomitant hemothorax.

Thoracic surgery outcomes for patients with Coronavirus Disease 2019.

OBJECTIVE: As the Coronavirus Disease 2019 pandemic continues, appropriate management of thoracic complications from Coronavirus Disease 2019 needs to be determined. Our objective is to evaluate which complications occurring in patients with Coronavirus Disease 2019 require thoracic surgery and to report the early outcomes. METHODS: This study is a single-institution retrospective case series at New York University Langone Health Manhattan campus evaluating patients with confirmed Coronavirus Disease 2019 infection who were hospitalized and required thoracic surgery from March 13 to July 18, 2020. RESULTS: From March 13 to August 8, 2020, 1954 patients were admitted to New York University Langone Health for Coronavirus Disease 2019. Of these patients, 13 (0.7%) required thoracic surgery. Two patients (15%) required surgery for complicated pneumothoraces, 5 patients (38%) underwent pneumatocele resection, 1 patient (8%) had an empyema requiring decortication, and 5 patients (38%) developed a hemothorax that required surgery. Three patients (23%) died after surgery, 9 patients (69%) were discharged, and 1 patient (8%) remains in the hospital. No healthcare providers were positive for Coronavirus Disease 2019 after the surgeries. CONCLUSIONS: Given the 77% survival, with a majority of patients already discharged from the hospital, thoracic surgery is feasible for the small percent of patients hospitalized with Coronavirus Disease 2019 who underwent surgery for complex pneumothorax, pneumatocele, empyema, or hemothorax. Our experience also supports the safety of surgical intervention for healthcare providers who operate on patients with Coronavirus Disease 2019.
