Hypoxemia After Endobronchial Valve Deployment for Persistent Air Leak

Area of Science:

• Pulmonology
• Anesthesiology
• Interventional Bronchoscopy

Background:

• Persistent air leaks are a challenging clinical problem, often requiring advanced interventions.
• Endobronchial valves (EBVs) are FDA-approved for lung-volume reduction and increasingly used for persistent air leaks.
• Anesthesiologists must understand the pathophysiology of patients undergoing EBV procedures for safe anesthetic management.

Purpose of the Study:

• To discuss the use of endobronchial valves (EBVs) in managing persistent air leaks.
• To highlight the importance of anesthesiologist awareness regarding EBV patient populations.
• To present a case necessitating EBV removal due to complications.

Main Methods:

• Review of endobronchial valve systems available in the US (Spiration Valve System, Zephyr Valve).
• Discussion of FDA approvals and compassionate use exemptions for EBVs.
• Case presentation of a patient requiring EBV removal due to persistent hypoxemia after transthoracic needle aspiration.

Main Results:

• Endobronchial valves are a viable option for persistent air leaks refractory to conservative therapy.
• EBV placement carries potential side effects requiring careful consideration.
• In this case, EBV removal was necessary due to persistent hypoxemia.

Conclusions:

• Anesthesiologists need to be aware of the pathophysiology associated with EBV use.
• Safe and effective anesthetic techniques are crucial during EBV placement and removal.
• Patient selection and monitoring are vital for optimizing outcomes with EBVs.
