Cannulation of the ascending aorta for cardiopulmonary bypass. Experience with 9,000 cases

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Cardiac Anesthesia

Background:

• Ascending aortic cannulation is a critical step in cardiopulmonary bypass.
• Ensuring safe and effective arterial return is paramount for patient outcomes.
• Minimizing complications associated with cannulation techniques is an ongoing surgical goal.

Purpose of the Study:

• To review the Cleveland Clinic's extensive experience with ascending aortic cannulation.
• To evaluate the safety and efficacy of this technique in a large patient cohort.
• To discuss the technical aspects, potential pitfalls, and complications of ascending aortic cannulation.

Main Methods:

• Retrospective review of over 9,000 patients undergoing ascending aortic cannulation.
• Analysis of complication rates, including dissection and other adverse events.
• Discussion of surgical technique, contraindications, and management strategies.

Main Results:

• Over 9,000 patients have undergone ascending aortic cannulation for arterial return.
• A single lethal dissection occurred in the entire patient cohort.
• Related complications were found to be minimal, highlighting the technique's safety.

Conclusions:

• Ascending aortic cannulation is a highly safe and effective method for arterial return in cardiac surgery.
• The technique is associated with a very low rate of severe complications.
• This communication provides valuable insights into the successful application and management of ascending aortic cannulation.
