Drs. Kaley El-Arab and Brandon Friedman are Emergency Medicine Residents at Carolinas Medical Center and interested in medical education and Critical Care. They have teamed with Ms. Emily Lipitz a PA with the Sanger Heart & Vascular Institute. Along with the guidance of Dr. Michael Gibbs, a notable Professor of Emergency Medicine, and Dr. John Symanski, a cardiologist from the Sanger Heart & Vascular Institute, they aim to help augment our understanding of emergent imaging of implanted devices. Follow along with the EMGuideWire.com team as they post these educational, self-guided radiology slides. This set will cover:

2. Disclosures
This ongoing imaging interpretation series is proudly sponsored by the
Emergency Medicine Residency Program at Carolinas Medical Center.
Sanger Heart & Vascular clinicians provide expert Cardiology input.
The goal is to promote widespread mastery of imaging interpretation.
There is no personal health information [PHI] within, and all ages have
been changed to protect patient confidentiality.
7. Extracorporeal Membrane Oxygenation (ECMO)
Definition: Extracorporeal mechanism for extended cardiac and pulmonary
support for individuals whose heart and lungs are unable to provide adequate
gas exchange or perfusion to sustain life.
Indication: Acute, severe reversible respiratory or cardiac failure with a high
risk of death that is refractory to conventional therapies.
Types of ECMO:
V-V = veno-venous
V-A = veno-arterial
10. V-V ECMO
Support for severe pulmonary failure (w/o cardiac failure).
Clinical Conditions Appropriate For V-V ECMO
• Pneumonia
• ARDS
• Acute GVHD
• Pulmonary contusion
• Smoke inhalation
• Status asthmaticus
• Airway obstruction
• Aspiration
• Bridge to lung transplant
• Drowning
11. Figure 2: V-V ECMO
Central venous blood is drained and
oxygenated blood is returned to the
right atrium. This technique requires
adequate perfusion by the heart.
12. V-V ECMO – Femoro-Jugular Cannulation
Figure 3: Femoro-Jugular Cannulation
Dual cannula systems drains blood from
the IVC through femoral access and
returns oxygenated blood to the right
atrium via internal jugular access.
13. V-V ECMO – Femoro-Femoral Cannulation
Figure 3: Femoro-Femoral Cannulation
Dual cannula system drains blood from
the IVC through femoral access and
returns oxygenated blood to the right
atrium via the opposite femoral vein.
14. V-V ECMO – Single Lumen Cannulation
Figure 4: Single Cannula System
A single dual-lumen catheter drains
blood from the SVC and IVC through
small ports and returns blood to the
right atrium through a parallel port,
requiring a single point of access.
