Delayed Spontaneous Pneumothorax in a Previously Healthy Nonventilated COVID-19 Patient.

Spontaneous pneumothorax is a serious and life-threatening complication of SARS-CoV-2 pneumonia. It most commonly occurs during the acute phase of the disease in patients with pre-existing lung disease (e.g. emphysema, bronchiectasis, cystic fibrosis, etc.) and in patients who require oxygen supplementation in any form (low-flow oxygen therapy, high-flow non-invasive or mechanical invasive or mechanical invasion). A rare case of a 52-year-old patient with a spontaneous pneumothorax who developed four weeks after PCR SARS-CoV-2 positivity was described. Interestingly, the patient did not have any factors that the literature considered risky for the development of this complication. During the acute phase of the disease, his condition did not require hospitalization. Imaging examinations could not clarify the cause of pneumothorax. With this case report, we want to point out the fact that spontaneous pneumothorax, as a rare and life-threatening complication of COVID-19 infection, may develop during recovery, and it is necessary to think about this complication in the differential diagnosis of dyspnoea.

A Secondary Spontaneous Pneumothorax in a Patient with COVID-19: Case report.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus, represents an unprecedented global threat. We report a 78-year-old male patient who presented to the Emergency Department at a tertiary care hospital in Muscat, Oman, in June 2020 with a one-day history of right chest pain and severe breathlessness. The patient was an ex-smoker and known to have idiopathic pulmonary fibrosis (IPF) with two previous pneumothoraces in the left lung. On presentation, the patient was breathless with an oxygen saturation of 90% on room air. Chest X-ray demonstrated bilateral lung infiltrates and right-sided pneumothorax. The patient tested positive for SARS CoV 2. A chest drain was placed which resulted in good resolution of the pneumothorax. The patient's condition improved remarkably and he was discharged after 17 days of hospitalisation. To the best of the authors' knowledge, this was the first case of pneumothorax reported in a patient infected with COVID-19 who was known to have underlying IPF.

One-year follow-up-case report of secondary tension pneumothorax in a COVID-19 pneumonia patient.

PURPOSE: The Coronavirus Disease 2019 (COVID-19) may result not only in acute symptoms such as severe pneumonia, but also in persisting symptoms after months. Here we present a 1 year follow-up of a patient with a secondary tension pneumothorax due to COVID-19 pneumonia. CASE PRESENTATION: In May 2020, a 47-year-old male was admitted to the emergency department with fever, dry cough, and sore throat as well as acute chest pain and shortness of breath. Sputum testing (polymerase chain reaction, PCR) and computed tomography (CT) confirmed infection with the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). Eleven days after discharge, the patient returned to the emergency department with pronounced dyspnoea after coughing. CT showed a right-sided tension pneumothorax, which was relieved by a chest drain (Buelau) via mini open thoracotomy. For a period of 3 months following resolution of the pneumothorax the patient complained of fatigue with mild joint pain and dyspnoea. After 1 year, the patient did not suffer from any persisting symptoms. The pulmonary function and blood parameters were normal, with the exception of slightly increased levels of D-Dimer. The CT scan revealed only discrete ground glass opacities (GGO) and subpleural linear opacities. CONCLUSION: Tension pneumothorax is a rare, severe complication of a SARS-CoV-2 infection but may resolve after treatment without negative long-term sequelae. LEVEL OF EVIDENCE: V.

Acute atraumatic peri-arrest tension gastrothorax presenting to the emergency department.

A 71-year-old woman was brought in by ambulance to the emergency department with sudden-onset difficulty in breathing whilst shopping at a large UK retail shopping centre. She had no respiratory history and portable chest X-ray revealed a huge gastrothorax, secondary pneumothorax and mediastinal shift. Clinical deterioration with haemodynamic instability required urgent decompression. Successful needle decompression followed by tube thoracostomy improved patient condition with no further complications. Surgical repair was performed but was delayed by COVID-19. This case provides a rare presentation of an acute life-threatening tension gastrothorax with difficult management considerations. A review of the management options is undertaken.

Delayed Spontaneous Bilateral Pneumothorax in a Previously Healthy Nonventilated COVID-19 Patient.

BACKGROUND: The novel coronavirus disease 2019 (COVID-19) is a recent viral outbreak that has rapidly spread to multiple countries worldwide. Little is known about COVID-19 infection-related complications. CASE REPORT: We report a patient who developed spontaneous bilateral pneumothorax after a recent COVID-19 infection. To our knowledge, this is the first reported case of spontaneous bilateral pneumothorax in a patient with recent confirmed severe acute respiratory syndrome coronavirus-2 infection without any risk factors for pneumothorax and who had not received positive pressure ventilation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: There may be a possible correlation between a recent COVID-19 infection and the development of spontaneous pneumothorax. The diagnosis of spontaneous pneumothorax should be considered in any patient with known or suspected recent COVID-19 infection who presents with new acute symptoms consistent with pneumothorax or sudden clinical deterioration.

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.

Spontaneous pneumothorax: An emerging complication of COVID-19 pneumonia.

Spontaneous Pneumothorax in the setting of coronavirus disease 19 (COVID-19) has been rarely described and is a potentially lethal complication. We report our institutional experience. Patients with confirmed COVID-19 who were admitted at 5 hospitals within the Inova health system between February 21 and May 2020 were included in the study. We identified 1619 patients, 22 patients (1.4%) developed spontaneous pneumothorax during their hospitalization without evidence of traumatic injury.

COVID-19 pneumonia and pneumothorax: case series.

Barotrauma is a commonly reported complication in critically ill patients with ARDS caused by different etiologies, it's rate is reported to be around %10. Pneumothorax/pneumomediastinum in COVID-19 patients seem to be more common and have different clinical characteristics. Here we report 9 patients who had pneumothorax and/or pneumomediastinum during their stay in the ICU. Patients who were admitted to ICU between March 2020 and December 2020, were reviewed for presence of pneumothorax, pneumomediastinum and subcutaneous emphysema during their ICU stay. Demographic characteristics, mechanical ventilation settings, documented ventilation parameters, outcomes were studied. A total of 161 patients were admitted to ICU during the study period, 96 were invasively ventilated. Nine patients had developed pneumothorax, pneumomediastinum and/or subcutaneous emphysema during their admission. Five of them were men and median age was 66.6 years. All patients were intubated and mechanically ventilated. All patients were managed conservatively. One patient was discharged from ICU, the others were lost due to other complications related to COVID-19. Upon detection of pneumothorax and/or mediastinum all patients were managed conservatively by limiting their PEEP and maximum inspiratory pressures and were followed by daily chest X-rays (CXR) for detection of any progress. None of the patients showed increase in size of their pneumothorax and/or pneumomediastinum. Hemodynamically instability due to pneumothorax and/or pneumomediastinum was not observed in any of the patients. Tension pneumothorax was not observed in any of the patients. Most common reason for death was sepsis due to secondary bacterial infections. Acute deterioration with rapid oxygen desaturation or palpation of crepitation over thorax and neck in a COVID-19 patient should prompt a search for pneumothorax or pneumomediastinum. Conservative management may be an option as long as the patients are stable.

Cavitary lung lesions and pneumothorax in a healthy patient with active coronavirus-19 (COVID-19) viral pneumonia.

Severe respiratory sequelae drive morbidity-associated with coronavirus 2019 (COVID-19) disease. We report a case of COVID-19 pneumonia complicated by cavitary lesions and pneumothorax in a young healthy male. Pneumothorax management with catheter thoracostomy and rapid resolution of the cavitary lesions are described. An extensive work-up for other causes a cavitation was negative and the temporal correlation of the cavities with COVID-19 infection plus their rapid resolution suggest a direct relationship. We propose a mechanism for cavitation secondary to microangiopathy, a cause of cavitation in the vasculitides and a known feature of COVID-19.

Spontaneous Pneumothorax: A Complication of Coronavirus Disease 2019 (COVID-19) Patients.

BACKGROUND: At present, the coronavirus disease 2019 (COVID-19) is spreading all over the world. The occurrence of spontaneous pneumothorax in these patients might be higher than the fact, and we should pay high clinical attention to them. METHOD: Data regarding clinical investigation, laboratory investigation, diagnosis, and treatment measures of 21 COVID-19 patients with spontaneous pneumothorax from January to March of 2020 were collected and analyzed in this study. RESULTS: Seven patients had a history of basic lung diseases. All patients used different methods of oxygen therapy before the occurrence of spontaneous pneumothorax according to the severity of the COVID-19, including 18 patients with ventilator-assisted breathing, 2 patients with bilevel positive airway pressure assisted breathing, and 1 patient with mask oxygen inhalation. All patients were confirmed cases of COVID-19 by chest CT (computed tomography) and virus nucleic acid detection and were found to have spontaneous pneumothorax through physical examination, bedside X-ray, and/or bedside ultrasound. 13 of 21 patients combined with pleural effusion at the same time. All the patients underwent closed thoracic drainage for spontaneous pneumothorax and the pleural effusion, if any. Nine patients died, and 12 patients recovered smoothly. CONCLUSION: Spontaneous pneumothorax might be an overlooked complication of COVID-19 patients and may be associated with poor prognosis.

Pneumothorax in patients with coronavirus disease 2019 pneumonia with invasive mechanical ventilation.

OBJECTIVES: Our goal was to evaluate the prevalence of and risk factors for pneumothorax in patients with invasive mechanical ventilation in the intensive care unit (ICU) diagnosed with coronavirus disease 2019 pneumonia. METHODS: The prevalence of pneumothorax was retrospectively reviewed in 107 patients diagnosed with coronavirus disease 2019 pneumonia and treated in an ICU in Turkey between 11 March 2020 and 30 April 2020. RESULTS: The patients were aged 19-92 years; 37 (34.6%) were women. Pneumothorax developed in 8 (7.5%) of the intubated patients. Four (50%) of the patients with pneumothorax and 68 (68.7%) of those without it died. In the univariable logistic regression analysis of the presence of comorbid diseases (P = 0.91), positive end-expiratory pressure (P = 0.18), compliance (P = 0.93), peak pressure (P = 0.41) and the Horowitz index (P = 0.13) did not show statistically significant effects in increasing the risk of pneumothorax. CONCLUSIONS: There was no significant increase or decrease in the risk of pneumothorax in patients treated with invasive mechanical ventilation after the diagnosis of coronavirus disease 2019-related pneumonia/acute respiratory distress syndrome. However, consideration of the risk of pneumothorax in these individuals may have the potential to improve the prognoses in such settings.

Management of Persistent Pneumothorax With Thoracoscopy and Bleb Resection in COVID-19 Patients.

Several studies have been published describing the clinical and radiographic findings of coronavirus disease 2019-related pneumonia. Therefore, there is currently a lack of pathologic data on its effects in intubated patients. Pneumothorax may occur rarely and results from a combination of fibrotic parenchyma and prolonged high-pressure ventilation. Chest drainage represents first-line treatment. However, in cases of persistent pneumothorax, thoracoscopy and bleb resection may be feasible options to reduce air leak and improve ventilation. This report describes the cases of 2 patients with coronavirus disease 2019 who were successfully treated with thoracoscopy, bleb resection, and pleurectomy for persistent pneumothorax.

Spontaneous pneumothorax as unusual presenting symptom of COVID-19 pneumonia: surgical management and pathological findings.

BACKGROUND: Spontaneous pneumothorax has been reported as a possibile complication of novel coronavirus associated pneumonia (COVID-19). We report two cases of COVID-19 patients who developed spontaeous and recurrent pneumothorax as a presenting symptom, treated with surgical procedure. An insight on pathological finding is given. CASE PRESENTATION: Two patients presented to our hospital with spontaneous pneumothorax associated with Sars-Cov2 infection onset. After initial conservative treatment with chest drain, both patients had a recurrence of pneumothorax during COVI-19 disease, contralateral (patient 1) or ipsilateral (patient 2) and therefore underwent lung surgery with thoracoscopy and bullectomy. Intraoperative findings of COVID-19 pneumonia were parenchymal atelectasis and vascular congestion. Lung tissue was very frail and prone to bleeding. Histological examination showed interstitial infiltration of lymphocytes and plasma cells, as seen in non specific interstitial pneumonia, together with myo-intimal thicknening of vessels with blood extravasation and microthrombi. CONCLUSIONS: Although rarely, COVID-19 may present with spontaneous pneumothorax. Lung surgery for pneumothorax in COVID-19 patients can be safely and effectively performed when necessary.
