Acute Lobar Atelectasis.

Authors:
John J Marini

Chest 2018 Dec 5. Epub 2018 Dec 5.

Pulmonary & Critical Care Medicine Divisions, Regions Hospital & University of Minnesota, Minneapolis/St. Paul, MN. Electronic address:

Lobar atelectasis (or collapse) is an exceedingly common, rather predictable, and potentially pathogenic companion to many forms of acute illness, postoperative care, and chronic debility. Readily diagnosed by using routine chest imaging and bedside ultrasound, the consequences from lobar collapse may be minor or serious, depending on extent, mechanism, patient vulnerability, abruptness of onset, effectiveness of hypoxic vasoconstriction, and compensatory reserves. Measures taken to reduce secretion burden, assure adequate secretion clearance, maintain upright positioning, reverse lung compression, and sustain lung expansion accord with a logical physiologic rationale.

Predictors of clinical outcome in emphysema patients with atelectasis following endoscopic valve therapy: A retrospective study.

Respirology 2016 10 1;21(7):1255-61. Epub 2016 Jun 1.

Member of the German Center for Lung Research, Heidelberg, Germany.

Background And Objective: The aim of endoscopic valve therapy in patients with emphysema is complete lobar atelectasis of the most emphysematous lobe. However, even after the radiological advent of atelectasis, great variability in clinical outcomes can be observed.

Methods: The baseline clinical measures (vital capacity (VC), forced expiratory flow in 1 s (FEV1 ), residual volume (RV) and 6-min walk test (6-MWT)) and computed tomography variables (low attenuation volume (LAV) of the target lobe, LAV% of the target and the ipsilateral untreated lobe and LAV of the target lobe to LAV of the target lung and to LAV of the total lung) of 77 patients with complete atelectasis following valve therapy were retrospectively examined to determine their impact on patient´s outcome (changes in VC, FEV1 , RV and 6-MWT from baseline to the time of atelectasis).

Bronchoscopic lung volume reduction with endobronchial valves for patients with heterogeneous emphysema and intact interlobar fissures (the BeLieVeR-HIFi study): a randomised controlled trial.

Lancet 2015 Sep 23;386(9998):1066-73. Epub 2015 Jun 23.

NIHR Respiratory Disease, Biomedical Research Unit at the Royal Brompton and Harefield NHS Foundation Trust, and Imperial College London, London, UK. Electronic address:

Background: Lung volume reduction surgery improves survival in selected patients with emphysema, and has generated interest in bronchoscopic approaches that might achieve the same effect with less morbidity and mortality. Previous trials with endobronchial valves have yielded modest group benefits because when collateral ventilation is present it prevents lobar atelectasis.

Methods: We did a single-centre, double-blind sham-controlled trial in patients with both heterogeneous emphysema and a target lobe with intact interlobar fissures on CT of the thorax. Read More

Middle lobe syndrome: a rare presentation of allergic bronchopulmonary aspergillosis.

Eur Ann Allergy Clin Immunol 2014 Jul;46(4):147-51

Department of Respiratory Medicine, Vallabhbhai Patel Chest Institute, University of Delhi, Delhi 110 007, India. Current affiliation: Department of Respiratory Medicine, Mata Chanan Devi Hospital, New Delhi, India.

Allergic bronchopulmonary aspergillosis (ABPA) is a disease predominantly seen in susceptible asthmatic subjects, due to a hypersensitivity phenomenon caused by colonisation of the airways by Aspergillus species. Although collapse, both lobar and segmental due to mucoid impaction, is not uncommon in ABPA, a middle lobe syndrome (MLS) secondary to ABPA is rather an uncommon association. We report this rare and unusual clinical presentation in a 36-year-old male, who presented for evaluation of a "non resolving pneumonia". Read More

Defeating the pores of Kohn.

Asian Cardiovasc Thorac Ann 2014 Jan;22(1):102-4

Department of Surgery, Prince of Wales Hospital, The Chinese University of Hong Kong, Hong Kong SAR.

In the treatment of emphysema with an endobronchial valve, entire lobar treatment is important in achieving adequate atelectasis. This case illustrates that without treatment of the entire lobe, it can fail to collapse even after several years, leading to treatment failure. Intralobar collateral ventilation through the pores of Kohn is demonstrated in this case, as endobronchial valve blockage of the remaining patent anterior segment resulted in the desired atelectasis and significant improvements in pulmonary function.

[Manifestations of lobar atelectasis on chest x-rays and correlation with computed tomography findings].

Radiologia 2014 May-Jun;56(3):257-67. Epub 2013 Nov 17.

Servicio de Radiodiagnóstico, Hospital Universitario Vall d'Hebron, Barcelona, España.

Atelectasis is an important indicator of potentially severe underlying disease that must be diagnosed as early as possible. One of the most common mechanisms is the reabsorption of air distal to respiratory tract obstruction. The chest x-ray is an excellent tool to diagnose atelectasis, and it is especially useful for ruling out central bronchial obstructions (e. Read More

Fetal MRI correlates with postnatal CT angiogram assessment of pulmonary anatomy in tetralogy of Fallot with absent pulmonary valve.

Congenit Heart Dis 2014 Jul-Aug;9(4):E105-9. Epub 2013 May 22.

Pediatric Cardiology, Lucile Packard Children's Hospital, Stanford University, Palo Alto, Calif, USA.

In tetralogy of Fallot with absent pulmonary valve, pulmonary stenosis and regurgitation results in significant pulmonary artery dilatation. Branch pulmonary artery dilatation often compresses the tracheobronchial tree, causing fluid trapping in fetal life and air trapping and/or atelectasis after birth. Prenatal diagnosis predicts poor prognosis, which depends on the degree of respiratory insufficiency from airway compromise and lung parenchymal disease after birth. Read More

Quantifying heterogeneity in emphysema from high-resolution computed tomography: a lung tissue research consortium study.

Acad Radiol 2013 Feb 30;20(2):181-93. Epub 2012 Oct 30.

Department of Internal Medicine, Division of Pulmonary and Critical Care Medicine, University of Texas Southwestern Medical Center, 5323 Harry Hines Blvd., Dallas, TX 75390-9034, USA.

Rationale And Objectives: To quantify spatial distribution of emphysema using high-resolution computed tomography (HRCT), we applied semiautomated analysis with internal attenuation calibration to measure regional air volume, tissue volume, and fractional tissue volume (FTV = tissue/[air + tissue] volume) in well-characterized patients studied by the Lung Tissue Research Consortium (LTRC).

Methods: HRCT was obtained at supine end-inspiration and end-expiration, and prone end-inspiration from 31 patients with mild, moderate, severe, or very severe emphysema (stages II-V, forced expiratory volume at 1 second >75%, 51%-75%, 21%-50% and ≤20% predicted, respectively). Control data were from 20 healthy non-smokers (stage I). Read More

Lobar collapse demystified: the chest radiograph with CT correlation.

Postgrad Med J 2012 Jun 25;88(1040):335-47. Epub 2012 Jan 25.

Radiology Department, University Hospital Aintree, Lower Lane, Liverpool L9 7AL, UK.

Collapse of a lobe of a lung is an important indicator of a range of conditions, including malignancy. Clinical symptoms and signs may suggest a diagnosis of lobar collapse; however, it is often diagnosed, and always needs to be confirmed, with radiological examination. The radiological signs may be subtle, difficult to interpret and sometimes confusing to both clinicians and radiologists. Read More

Predicting the need for palliative thoracic radiation after first-line chemotherapy for advanced nonsmall cell lung carcinoma.

Cancer 2012 May 20;118(10):2744-51. Epub 2011 Sep 20.

Department of Radiation Oncology, University of North Carolina, Chapel Hill, NC, USA.

Background: The objective of this secondary analysis was to identify patients with selected stage IIIB/IV nonsmall cell lung carcinoma and good performance status who were at high risk for requiring subsequent palliative thoracic radiotherapy after initial treatment with first-line chemotherapy.

Methods: The authors conducted a pooled analysis of patients at a single institution who enrolled onto 10 prospective phase 2 and 3 clinical trials that involved first-line, platinum-based chemotherapy. Baseline lung-related characteristics before trial enrollment were analyzed as possible prognostic factors for freedom from pulmonary events (defined either as subsequent thoracic radiation or as a new collapsed lung, which is an indication for thoracic radiation).

Surgical technique of lower lobe lung transplantation.

Ann Thorac Surg 2011 Aug;92(2):e39-42

Department of Cardiovascular Surgery, University Heart Center Hamburg, Hamburg, Germany.

Among patients with end-stage lung disease awaiting lung transplantation, pediatric and small adult patients have a significantly lower chance of getting size-matched pulmonary grafts in time because of the severe scarcity of small donors. It is our strategy to perform lobar lung transplantations in small recipients with restrictive pulmonary disease once their clinical status demands urgent transplantation. Here we describe our surgical technique and discuss the benefits and risks of this procedure. Read More
