Bronchoscopy does not have a major role in the management of PVOD but it may be performed to rule out other lung diseases in cases of an atypical presentation. Hyperemia of the small airway mucosa with vascular engorgement in the form of bright red, longitudinal streaks has been reported. The trachea and main bronchi may be spared because the venous drainage of the central airways is into bronchial veins, which are not involved. Bronchoalveolar lavage may suggest chronic alveolar hemorrhage.

Transbronchial lung biopsy is contraindicated because of the presence of pulmonary hypertension and the risk of excessive bleeding.
