Subclavian artery approach for insertion of intra-aortic balloon.

Subperiosteal clavicular resection for access to the subclavian artery is described. In those patients requiring intra-aortic balloon placement in the nonsurgical setting, such an approach provides a reasonably benign alternative when aortoiliac atherosclerosis prevents the usual retrograde femoral placement. Little morbidity or functional compromise is associated with clavicular wedge resections, and the anatomic availability of a large artery without the need for major surgical maneuvers in these gravely ill patients is a distinct advantage.
