Axillary Approach for Venoarterial Extracorporeal Membrane Oxygenation Cannulation

Abstract

Extracorporeal membrane oxygenation support (ECMO) is a form of mechanical circulatory support that is used in patients with severe dysfunction of heart or lung or both. Depending on whether it is venovenous or venoarterial support, it can temporarily substitute for circulation and ventilation while the underlying cause is addressed. Traditional approach for cannulation usually involves the femoral vessels. This is due to the easy accessibility, larger lumen of vessels, and physician expertise and training in femoral approach. However, in certain circumstances like critical lower extremity ischemia, crush injury or trauma to lower extremity, and lower extremity infections (like necrotizing fasciitis), this approach is not practical. In these situations, axillary vasculature provides a good substitute for ECMO cannulation.

Ethical Dilemma: Should Continuous Intravenous Drug Use Affect Appropriate Management in Prosthetic Valve Endocarditis?

“…For patients who are in refractory shock (septic and cardiogenic combined), some form of mechanical circulatory support may be required. There have been case reports of valve replacement procedures including surgeries being performed under these supports [17,18]. Each invasive modality of treatment has some implications in the form of short-and long-term complications.…”
