Rounded atelectasis of the lung is well described in medical literature, but still difficult to diagnose. Since lesions give no clinical symptoms in patients, radiologists are often the first to recognize the round lesion in an X-ray picture or a CT scan. Rounded atelectasis is an atypical form of lung collapse that usually occurs adjacent to scarred pleura and can be mistaken for lung cancer. ...

Atelectasis was reported as a favorable prognostic sign of pulmonary carcinoma; however, the underlying mechanism in those patients is not known. In this study, we aimed to investigate prospectively the potential impact of atelectasis and/or obstructive pneumonitis (AO) on survival and the relation between atelectasis and some laboratory blood parameters. The study was conducted on 87 advanced ...

INTRODUCTION Although radiation therapy (RT) is an effective treatment for malignant atelectasis, its accurate delivery is challenging because of difficulty differentiating between tumor and atelectatic lung. Furthermore, reexpansion of lung during treatment repositions tumor and normal structures necessitating replanning to ensure treatment accuracy. Facilitating lung reexpansion before initia...

Background Atelectasis and poorly ventilated lung areas are negative consequences of general anesthesia observed in adult as well as in children. The reported incidence of this anesthesia-induced atelectasis in children is high and comes from 83 % to almost 100 %. The diagnosis of this entity is difficult to do at the bedside; they are commonly small and mostly invisible to standard chest X-ray...

A preliminary assessment of the effectiveness of the Bartlett-Edwards incentive spirometer was made using it as part of the post-operative treatment of 34 patients after open-heart surgery. Its effects on atelectasis were assessed by measuring vital capacity, arterial oxygen tensions, clinical signs and radiological changes. It was found that vital capacity fell after surgery to 41.5 per cent o...

Introduction. The aim of the study was to assess changes of regional ventilation distribution at the level of the 3rd intercostal space in the lungs of morbidly obese patients as a result of general anaesthesia and laparoscopic surgery as well as the relation of these changes to lung mechanics. We also wanted to determine if positive end-expiratory pressure of 10 cm H2O prevents the expected at...

Round atelectasis is a benign inflammatory condition most frequently observed in patients with asbestos exposure but it can also result from a variety of chronic pleural diseases like infection. It has not previously been described in sarcoidosis. We report the occurrence of round atelectasis in four previously diagnosed sarcoidosis patients who were under follow up at our outpatient clinic. Th...

Pulmonary atelectasis in children was often found to have cleared soon after diagnostic bronchoscopy. Re-ventilation occurred even in children in whom the collapse had resisted the usual methods of treatment during preceding weeks or months. It was, therefore, decided to bronchoscope every child with pulmonary collapse provided the collapse was known to have existed for more than five weeks. In...

Postoperative atelectasis should be avoided in surgical patients with impaired pulmonary function. Nasal high-flow (NHF) therapy delivered by the Optiflow™ system (Fisher & Paykel Healthcare Ltd., Auckland, New Zealand) is a new, simple device that supplies heated and humidified oxygen gas at >30 L/min via a large-bore nasal cannula. We herein describe a case in which respiratory support with N...
