Lobar Quantification by Ventilation/Perfusion SPECT/CT in Patients with Severe Emphysema Undergoing Lung Volume Reduction with Endobronchial Valves.

Respiration 2019;98(3):230-238. Epub 2019 Jun 5.

Department of Clinical Physiology, Nuclear Medicine and PET, Rigshospitalet, University Hospital of Copenhagen, Copenhagen, Denmark,

Background: Endoscopic lung volume reduction (ELVR) therapy using one-way valves is used to treat chronic obstructive pulmonary disease patients with severe heterogeneous emphysema. A successful treatment results in atelectasis of the treated pulmonary lobe with subsequent reduction of ventilation (V) and perfusion (Q).

Objective: We evaluated the effects of ELVR on the targeted lobe using a new 3-dimensional ventilation and perfusion (V/Q) single-photon emission computed tomography (SPECT)/computed tomography (CT) analysis, which allows for simultaneous semi-automatic lobar pulmonary quantification of volume, ventilation and perfusion, on the first consecutive patients treated with ELVR at Rigshospitalet, Denmark.

Acute Lobar Atelectasis.

Authors:
John J Marini

Chest 2019 05 5;155(5):1049-1058. 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.

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

Allergic bronchopulmonary aspergillosis presenting as lobar or total lung collapse.

Pneumonol Alergol Pol 2015 ;83(2):144-50

Department of Respiratory Allergy and Applied Immunology, National Centre of Respiratory Allergy, Asthma and Immunology, India.

Introduction: Allergic bronchopulmonary aspergillosis (ABPA) is a T-helper cell 2 (Th2) mediated hypersensitive lung disorder in response to Aspergillus that usually affects asthmatic and cystic fibrosis (CF) patients. ABPA rarely presents as lung collapse and such kind of presentation is very rare in non asthmatic patients. We are presenting a series of three cases in which ABPA presented as lobar or total lung collapse. 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
