Inter- and intra-observer variability of radial-endobronchial ultrasound image interpretation for peripheral pulmonary lesions.

Background: Radial probe endobronchial ultrasound (R-EBUS) is often utilized in guided bronchoscopy for the diagnosis of peripheral pulmonary lesions. R-EBUS probe positioning has been shown to correlate with diagnostic yield, but overall diagnostic yield with this technology has been inconsistent across the published literature. Currently there is no standardization for R-EBUS image interpretation, which may result in variability in grading concentricity of lesions and subsequently procedure performance.

Localization of Peripheral Pulmonary Lesions Using a Method of Computed Tomography-Anatomic Correlation and Radial Probe Endobronchial Ultrasound Confirmation.

Rationale: Peripheral pulmonary lesions requiring a diagnosis continue to present challenges to clinicians. One significant barrier is the inability to reliably locate peripheral lesions by bronchoscopic approaches. Multiplanar computed tomographic (CT) scan reconstruction is available to most physicians and provides axial, coronal, and sagittal images that may be used to estimate target lesion location and guide bronchoscopists during procedures.

Pleural Myiasis Associated With Pleural Angiosarcoma.

Myiasis refers to a parasitic infestation of vertebrate mammals by dipterous larvae (maggots) of higher flies. Infections in humans typically occur in tropical and subtropical regions, regions with limited medical access, and areas with poor hygiene and living conditions. Infestations in humans have been described in subcutaneous, nasal, ocular, oropharyngeal, and orotracheal cases; however, reports of pulmonary myiasis in humans in the United States and other developed countries are extremely rare.

Radial probe endobronchial ultrasound for peripheral pulmonary lesions. A 5-year institutional experience.

Rationale: Technological advances have improved the ability of bronchoscopists to access peripheral pulmonary lesions for tissue sampling. Radial probe endobronchial ultrasound (EBUS) provides real-time feedback to guide biopsies of peripheral lesions, thereby potentially improving diagnostic yield over conventional bronchoscopy.

Objectives: We assessed the overall diagnostic yield of peripheral bronchoscopy using radial probe EBUS for peripheral pulmonary lesions, as well as factors that might influence the diagnostic yield, such as radial ultrasound view, lesion size, and ability to locate the peripheral lesion.

Idiopathic subglottic stenosis: an evolving therapeutic algorithm.

Objectives/hypothesis: Idiopathic subglottic stenosis (ISS) is a rare type of airway stenosis of unclear etiology. Open resection, while effective, remains a complex surgery and requires a hospital stay. Endoscopic management is often preferred but has historically been associated with a high recurrence rate.

Managing iatrogenic pneumothorax and chest tubes.

Iatrogenic pneumothorax has become an increasingly recognized complication of routine outpatient procedures, such as transthoracic needle biopsies of the lung and transbronchial lung biopsies. Patients with clinically significant pneumothorax are typically managed with evacuation via a percutaneously placed catheter or chest tube. Tube thoracotomy and chest tube management have traditionally been performed by cardiothoracic surgeons; however, with the increasing number of interventional radiologists and interventional pulmonologists, more chest tubes are being placed by specialists who do not admit and manage patients in the hospital setting.

Aortic tumor or mobile thrombus?

Isolated large mobile mass in the thoracic aorta can be due to thrombus or, rarely, aortic tumor. We report the case of a 61-year-old man with no history of medical problems presenting with neurologic deficits and in whom a large mobile echogenic mass in the distal aortic arch was found with transesophageal echocardiography. Given his few cardiovascular risk factors and absence of other systemic symptoms, he received anticoagulant therapy.
