Vascular Complications in Patients with ECMO Support after Cardiac Surgery

Area of Science:

• Cardiovascular Surgery
• Critical Care Medicine
• Biomedical Engineering

Background:

• Vascular complications are a significant concern in patients requiring extracorporeal membrane oxygenation (ECMO) after cardiac surgery.
• Understanding the risks associated with different ECMO cannulation techniques is crucial for patient outcomes.

Purpose of the Study:

• To compare vascular complications between percutaneous and open femoral incision techniques for VA-ECMO cannulation in post-cardiotomy patients.
• To evaluate the impact of cannulation method on thromboembolic events, bleeding, hematomas, and infections.

Main Methods:

• Retrospective analysis of 84 post-cardiotomy patients undergoing VA-ECMO via peripheral cannulation.
• Comparison of vascular complications between percutaneous (n=52) and open femoral incision (n=32) ECMO placement groups.
• Statistical analysis of complication rates, including thromboembolism, hematomas, bleeding, leakage, wound infections, and revisions.

Main Results:

• Percutaneous ECMO placement showed a significantly higher incidence of vascular thromboembolism and hematomas (p < 0.05).
• Open femoral incision technique was associated with significantly more bleeding and leakage (p = 0.04).
• No significant differences were observed in wound infections or inguinal revisions between the groups. Mortality from vascular ischemia was 81.2%.

Conclusions:

• The open technique for VA-ECMO cannulation may offer a lower risk of thromboembolic events and hematomas compared to the percutaneous approach.
• The percutaneous technique may be associated with a higher risk of bleeding and leakage.
• Both cannulation methods demonstrated comparable outcomes regarding overall in-hospital mortality and wound infections.
