Innominate artery cannulation in aortic surgery: A systematic review

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Surgery

Background:

• The innominate artery is an alternative cannulation site for cardiopulmonary bypass in thoracic aortic surgery.
• Establishing cardiopulmonary bypass and cerebral perfusion are critical in complex aortic procedures.

Purpose of the Study:

• To systematically review the safety and efficacy of innominate artery cannulation in thoracic aortic surgery.
• To evaluate the outcomes of patients undergoing aortic surgery with innominate artery cannulation.

Main Methods:

• Systematic literature search of PubMed, Embase, Scopus, and Ovid databases.
• Inclusion of studies utilizing innominate artery cannulation for cardiopulmonary bypass and cerebral perfusion in thoracic aortic surgery.
• Data review up to September 2018.

Main Results:

• 36% of 2,290 patients had acute type A aortic dissection.
• Surgical procedures included aortic root, ascending/hemi-arch, and total aortic arch replacement.
• Postoperative stroke rate was 1.25%, temporary neurological deficit was 4.8%, and 30-day mortality was 2.7%.

Conclusions:

• Innominate artery cannulation is a safe technique for thoracic aortic surgery.
• It serves as a reliable route for cardiopulmonary bypass and cerebral perfusion in selected cases.
