Dynamic anterior mediastinal mass compression of the superior vena cava during airway stent deployment

Mediastinal masses carry the intrinsic potential for life-threatening perioperative complications that directly impact anesthetic management, since well-recognized cardiopulmonary failure either chronic or acute may occur. A 48-year-old patient with known airway collapse due to an anterior mediastinal mass presents for airway stent insertion, that upon manipulation of the airway, a sudden and reproducible cardiovascular collapse ensued, due to dynamic compression of the superior vena cava, witnessed via endobronchial ultrasound. Close communication with the procedural team before and during manipulation of the patient’s airway plays a paramount role to assure positive clinical outcomes.
