Background: The aim of this study is to describe surgical findings, treatment and outcome of spontaneous pneumothorax (SP) secondary to suspected migrating vegetal foreign body (MVFB).

Methods: This retrospective study included dogs with computed tomography (CT) consistent with SP suspected to be secondary to MVFB that underwent thoracic surgery. They were divided into two groups according to whether CT identified (group 1) or only suspected (group 2) an MVFB. Read More

POCUS - Thoracic Sonography in Times of Corona: What Sonographing Family Physicians Should Examine When performing chest sonography of patients with symptoms such as respiratory infection, dyspnea and chest pain, the primary goal is to find or exclude significant diagnoses such as pneumothorax, pleural effusion, pulmonary edema, tumors, pulmonary emboli, etc. as the cause of the symptoms. If infection with SARS-CoV-2 is present, COVID-19 pneumonia can be confirmed or excluded as the cause of the symptoms with a high degree of probability based on the sonographic signs. Read More

Secondary spontaneous pneumothorax associated with pulmonary Mycobacterium avium complex (MAC) infection is often difficult to treat. Pneumothorax associated with pulmonary MAC is characterized by a large fistula with a cavity or bronchodilation, and pleural thickening due to pleurisy. Herein, we report two cases of pneumothorax with pulmonary MAC successfully treated by minimally invasive thoracoscopic intra-fistula filling with a suture closure method. Read More

Background: Trauma is the leading cause of death in young adults up to the age of 45 years. Hemothorax is a frequent consequence of penetrating thoracic trauma, and is usually associated with pneumothorax and pneumoderma. Intercostal arterial bleeding or intrathoracic hemorrhage occurs after penetrating thoracic trauma, and uncontrolled bleeding is the main cause of death. Read More

There is a paucity of studies on the correlation between chest radiograph and ultrasound (US) in children. Our objective was to study the correlation between bedside chest radiograph and ultrasound findings in 413 children with 1002 episodes of chest radiograph and US enrolled for a prospective, double-blinded observational study in a multidisciplinary paediatric intensive care unit. Weighted statistic for agreement was different for right and left lungs and varied from 50% for left pleural effusion to 98% for right pneumothorax. Read More

Objective: This study was designed to explore the diagnostic value of multi-slice spiral CT (MSCT) scanning in lung compression ratio of patients with pulmonary contusion complicated by pneumothorax or hydropneumothorax.

Methods: Seventy-eight patients with pulmonary contusions complicated by pneumothorax or hydropneumothorax treated in the Department of Emergency Surgery of our hospital were examined by CT and X-ray, and the diagnostic value of these two methods was observed. The correlation of lung compression ratio measured by multiplanar reconstruction (MPR) and volume rendering (VR) with W/D ratio was studied, and the formula between VR-measured lung compression ratio and W/D ratio was constructed using a one-variable linear regression equation.

Background: Microwave ablation of lung nodules may provide a faster, larger and more predictable ablation zone than other energy sources, while bronchoscopic transbronchial ablation has theoretical advantage of fewer pleural-based complications than percutaneous approach. Our study aims to determine whether the novel combination of bronchoscopic approach and microwave ablation in management of lung nodules is technically feasible, safe and effective.

Methods: This is a retrospective analysis of a single center experience in electromagnetic navigation bronchoscopy microwave ablation in hybrid operating room. Read More

Although US of the lungs is increasingly used clinically, diagnostic radiologists are not routinely trained in its use and interpretation. Lung US is a highly sensitive and specific modality that aids in the evaluation of the lungs for many different abnormalities, including pneumonia, pleural effusion, pulmonary edema, and pneumothorax. This review provides an overview of lung US to equip the diagnostic radiologist with knowledge needed to interpret this increasingly used modality. Read More

Pneumothorax, the accumulation of air between the visceral and parietal pleurae, represents a potentially serious cause of chest pain in patients presenting to the emergency department. While there are known risk factors for spontaneous pneumothorax, in rare cases dry needling and acupuncture, forms of complementary and alternative medicine, have been known to result in pneumothorax. We present a case of a 38-year-old healthy female who presented with acute onset of pleuritic chest pain to the Emergency Department. Read More
