In recent years, the placement of endovascular stent-graft prostheses has gained increasing popularity as a low-risk, less-invasive, and less-traumatic procedure for thoracic aortic aneurysm (TAA) compared with traditional surgical intervention.1 Similarly, technical developments have facilitated stent implantation to restore airway patency in patients with airway obstruction.2
We describe a case of recurrent respiratory insufficiency caused by compression of the tracheobronchial tree by an extensive TAA in which we used a multistep endobronchial-endovascular technique.
Clinical Summary
A 78-year-old man with a history of TAA was admitted to the emergency department because of recurrence of respiratory failure. He was unconscious, with cyanosis and severe hypertension (220/120 mm Hg). On thoracic examination, wheezes were heard at the lower third of the left lung. Arterial blood gas analysis revealed an arterial oxygen partial pressure of 40 mm Hg, a carbon dioxide partial pressure of 120 mm Hg, and a pH value of 6.93. The patient was intubated and mechanically ventilated. Preoperative chest radiography and computed tomography showed a large aortic aneurysm with compression of the tracheobronchial tree (Figure 1). Fiberoptic bronchoscopy confirmed extrinsic compression of the trachea just proximal to the carina and a significant narrowing of
