Abstract
Axillary artery cannulation for cardiopulmonary bypass has been described previously as a safe and reliable technique, with a low risk of atheroemboli, avoidance of malperfusion in aortic dissection and facilitation of selective antegrade cerebral perfusion during hypothermic circulatory arrest. The aim of this study was to document the broad applicability of axillary cannulation and its associated morbidity and identify where it was not possible to use planned axillary cannulation. A retrospective review of a single surgeon's 10-year experience of axillary cannulation using the side-graft technique in 184 consecutive patients (age 22–92 years) in aortic and complex cardiac surgery from July 2002 to June 2012. There were no intraoperative deaths and no major complications related to axillary artery use. There were six postoperative deaths unrelated to axillary artery cannulation. Six patients (3.3%) had minor complications as a direct result of axillary cannulation including seroma, haematoma, chronic pain and pectoralis major muscle atrophy. There were 10 cases where planned axillary cannulation was abandoned, due to inadequate size of the axillary artery in 8 patients and axillary artery dissection and morbid obesity in 1 patient each. Axillary artery cannulation is an ideal arterial inflow site in cases where the ascending aorta is unsuitable as it is safe, reliable and reduces the risks of atheroembolization and malperfusion. Major complications are rare with this meticulous technique and it is our standard practice in complex cardiac and aortic surgery.
