The comet-tail artifact. An ultrasound sign of alveolar-interstitial syndrome.
Lichtenstein D, Mézière G, Biderman P, Gepner A, Barré O. Lichtenstein D, et al. Among authors: gepner a. Am J Respir Crit Care Med. 1997 Nov;156(5):1640-6. doi: 10.1164/ajrccm.156.5.96-07096. Am J Respir Crit Care Med. 1997. PMID: 9372688
In a prospective study, we examined 250 consecutive patients in a medical intensive care unit: 121 patients with radiologic alveolar-interstitial syndrome (disseminated to the whole lung, n = 92; localized, n = 29) and 129 patients without radiologic evidence of alv …

A-lines and B-lines: lung ultrasound as a bedside tool for predicting pulmonary artery occlusion pressure in the critically ill.
Lichtenstein DA, Mezière GA, Lagoueyte JF, Biderman P, Goldstein I, Gepner A. Lichtenstein DA, et al. Among authors: gepner a. Chest. 2009 Oct;136(4):1014-1020. doi: 10.1378/chest.09-0001. Chest. 2009. PMID: 19809049
The A-line is a horizontal artifact indicating a normal lung surface. The B-line is a kind of comet-tail artifact indicating subpleural interstitial edema. ...We defined A-predominance as a majority of anterior A-lines and B-predom …

Ultrasound diagnosis of alveolar consolidation in the critically ill.
Lichtenstein DA, Lascols N, Mezière G, Gepner A. Lichtenstein DA, et al. Among authors: gepner a. Intensive Care Med. 2004 Feb;30(2):276-281. doi: 10.1007/s00134-003-2075-6. Epub 2004 Jan 13. Intensive Care Med. 2004. PMID: 14722643
OBJECTIVE: Alveolar consolidation is a basic concern in critically ill patients. Radiography is not a precise tool, and referral to CT raises problems (transport, irradiation). ...SETTING: The medical ICU of a university-affiliated teaching hospital. PATIENTS …

Ultrasound diagnosis of occult pneumothorax.
Lichtenstein DA, Mezière G, Lascols N, Biderman P, Courret JP, Gepner A, Goldstein I, Tenoudji-Cohen M. Lichtenstein DA, et al. Among authors: gepner a. Crit Care Med. 2005 Jun;33(6):1231-8. doi: 10.1097/01.ccm.0000164542.86954.b4. Crit Care Med. 2005. PMID: 15942336
Among 302 analyzable controls, 65 had absent lung sliding, 16 of them showed an A line sign, and none showed a lung point. For the diagnosis of occult pneumothorax, the abolition of lung sliding alone had a sensitivity of 100% and a specificity of 78%. …

The "lung point": an ultrasound sign specific to pneumothorax.
Lichtenstein D, Mezière G, Biderman P, Gepner A. Lichtenstein D, et al. Among authors: gepner a. Intensive Care Med. 2000 Oct;26(10):1434-40. doi: 10.1007/s001340000627. Intensive Care Med. 2000. PMID: 11126253
OBJECTIVE: We studied an ultrasound sign, the fleeting appearance of a lung pattern (lung sliding or pathologic comet-tail artifacts) replacing a pneumothorax pattern (absent lung sliding plus exclusive horizontal lines) in a particular location of the chest …

The comet-tail artifact: an ultrasound sign ruling out pneumothorax.
Lichtenstein D, Mezière G, Biderman P, Gepner A. Lichtenstein D, et al. Among authors: gepner a. Intensive Care Med. 1999 Apr;25(4):383-8. doi: 10.1007/s001340050862. Intensive Care Med. 1999. PMID: 10342512 Clinical Trial.
Horizontal artifacts had a sensitivity and a negative predictive value of 100% and a specificity of 60% for the diagnosis of pneumothorax. Horizontal artifacts and absent lung sliding, when combined, had a sensitivity and a negative predictive v …

The "sinusogram", a real-time ultrasound sign of maxillary sinusitis.
Lichtenstein D, Biderman P, Mezière G, Gepner A. Lichtenstein D, et al. Among authors: gepner a. Intensive Care Med. 1998 Oct;24(10):1057-61. doi: 10.1007/s001340050716. Intensive Care Med. 1998. PMID: 9840240
OBJECTIVE: To describe a real-time ultrasound sign, the visualization of the cavity and the walls of the maxillary sinus ("sinusogram"), and to assess its correlation with total opacity of the sinus. ...SETTING: The medical ICU of a university-affiliated hospital. P …
