Background:
Central airway obstruction near the right upper lobe (RUL) airway orifice poses a dilemma for the clinician. Maintaining ventilation to the right middle and right lower lobes is of utmost importance. However, preserving ventilation to the RUL is desirable as well especially in patients with significant dyspnea.
Case Presentation:
In this case report, we describe telescoping 2 covered self-expanding hybrid stents to relieve airway obstruction while maintaining RUL ventilation.
Conclusions:
Review of current literature revealed several additional documented approaches to overcome this challenge. The choice of intervention needs to be deliberated based on the available stents, delineation of the airway obstruction, and the patient's anatomy.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
