An unusual complication related to axillary artery cannulation for acute type A aortic dissection repair

Abstract

Axillary artery cannulation is a safe, feasible and reliable method for acute type A dissection repair. Axillary artery cannulation has several advantages, including antegrade perfusion of the aorta and selective unilateral perfusion of brain. With increased preference of this technique, problems and complication are more commonly encountered. We report right shoulder dislocation as an unusual complication of axillary cannulation in this letter. Cardiopulmonary bypass (CPB) via the axillary artery has become an alternative perfusion site, especially in acute aortic dissections.[1] The complications of axillary artery cannulation include embolization, brachial plexus injury, wound hematomas, and infection.[1-3] We report the case of a right shoulder dislocation as an unusual complication of axillary cannulation.
