[Linear endobronchial ultrasound as the initial diagnostic tool in patients with indications of mediastinal disease].

Background And Objective: Linear endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has proven useful for sampling mediastinal masses and nodes and for staging lung cancer. The aim of this study was to assess the usefulness of this diagnostic tool in patients with indications of mediastinal disease that could not be diagnosed by noninvasive methods or white light bronchoscopy.

Patients And Methods: All patients undergoing linear EBUS-TBNA for the diagnosis of mediastinal masses and/or adenopathy at our endoscopy unit were included in the study.

[Severe pulmonary hypertension and Takayasu arteritis].

Takayasu arteritis is an inflammatory disease that affects large vessels, especially the aorta and its branches. The clinical features of the disease depend on which arteries are affected. Although pulmonary artery involvement is common, only rarely is this the main clinical manifestation.
